OBIEE 11.1.1 - How to Enable Caching in Internet Information Services (IIS) 7.0+

- by Ahmed A

Follow these steps to configure static file caching and content expiration if you are using IIS 7.0 Web Server with Oracle Business Intelligence. Tip: Install IIS URL Rewrite that enables Web administrators to create powerful outbound rules. Following are the steps to set up static file caching for IIS 7.0+ Web Server: 1. In “web.config” file for OBIEE static files virtual directory (ORACLE_HOME/bifoundation/web/app) add the following highlight in bold the outbound rule for caching:<?xml version="1.0" encoding="UTF-8"?><configuration> <system.webServer> <urlCompression doDynamicCompression="true" /> <rewrite> <outboundRules> <rule name="header1" preCondition="FilesMatch" patternSyntax="Wildcard"> <match serverVariable="RESPONSE_CACHE_CONTROL" pattern="*" /> <action type="Rewrite" value="max-age=604800" /> </rule> <preConditions> <preCondition name="FilesMatch"> <add input="{RESPONSE_CONTENT_TYPE}" pattern="^text/css|^text/x-javascript|^text/javascript|^image/gif|^image/jpeg|^image/png" /> </preCondition> </preConditions> </outboundRules> </rewrite> </system.webServer></configuration>2. Restart IIS.

Creating and using VM Groups in VirtualBox

- by Fat Bloke

With VirtualBox 4.2 we introduced the Groups feature which allows you to organize and manage your guest virtual machines collectively, rather than individually. Groups are quite a powerful concept and there are a few nice features you may not have discovered yet, so here's a bit more information about groups, and how they can be used.... Creating a group Groups are just ad hoc collections of virtual machines and there are several ways of creating a group: In the VirtualBox Manager GUI: Drag one VM onto another to create a group of those 2 VMs. You can then drag and drop more VMs into that group; Select multiple VMs (using Ctrl or Shift and click) then select the menu: Machine...Group; or press Cmd+U (Mac), or Ctrl+U(Windows); or right-click the multiple selection and choose Group, like this: From the command line: Group membership is an attribute of the vm so you can modify the vm to belong in a group. For example, to put the vm "Ubuntu" into the group "TestGroup" run this command: VBoxManage modifyvm "Ubuntu" --groups "/TestGroup" Deleting a Group Groups can be deleted by removing a group attribute from all the VMs that constitute that group. To do this via the command-line the syntax is: VBoxManage modifyvm "Ubuntu" --groups "" In the VirtualBox Manager, this is more easily done by right-clicking on a group header and selecting "Ungroup", like this: Multiple Groups Now that we understand that Groups are just attributes of VMs, it can be seen that VMs can exist in multiple groups, for example, doing this: VBoxManage modifyvm "Ubuntu" --groups "/TestGroup","/ProjectX","/ProjectY" Results in: Or via the VirtualBox Manager, you can drag VMs while pressing the Alt key (Mac) or Ctrl (other platforms). Nested Groups Just like you can drag VMs around in the VirtualBox Manager, you can also drag whole groups around. And dropping a group within a group creates a nested group. Via the command-line, nested groups are specified using a path-like syntax, like this: VBoxManage modifyvm "Ubuntu" --groups "/TestGroup/Linux" ...which creates a sub-group and puts the VM in it. Navigating Groups In the VirtualBox Manager, Groups can be collapsed and expanded by clicking on the carat to the left in the Group Header. But you can also Enter and Leave groups too, either by using the right-arrow/left-arrow keys, or by clicking on the carat on the right hand side of the Group Header, like this: . ..leading to a view of just the Group contents. You can Leave or return to the parent in the same way. Don't worry if you are imprecise with your clicking, you can use a double click on the entire right half of the Group Header to Enter a group, and the left half to Leave a group. Double-clicking on the left half when you're at the top will roll-up or collapse the group. Group Operations The real power of Groups is not simply in arranging them prettily in the Manager. Rather it is about performing collective operations on them, once you have grouped them appropriately. For example, let's say that you are working on a project (Project X) where you have a solution stack of: Database VM, Middleware/App VM, and a couple of client VMs which you use to test your app. With VM Groups you can start the whole stack with one operation. Select the Group Header, and choose Start: The full list of operations that may be performed on Groups are: Start Starts from any state (boot or resume) Start VMs in headless mode (hold Shift while starting) Pause Reset Close Save state Send Shutdown signal Poweroff Discard saved state Show in filesystem Sort Conclusion Hopefully we've shown that the introduction of VM Groups not only makes Oracle VM VirtualBox pretty, but pretty powerful too. - FB

jtreg update, March 2012

- by jjg

There is a new update for jtreg 4.1, b04, available. The primary changes have been to support faster and more reliable test runs, especially for tests in the jdk/ repository. [ For users inside Oracle, there is preliminary direct support for gathering code coverage data using jcov while running tests, and for generating a coverage report when all the tests have been run. ] -- jtreg can be downloaded from the OpenJDK jtreg page: http://openjdk.java.net/jtreg/. Scratch directories On platforms like Windows, if a test leaves a file open when the test is over, that can cause a problem for downstream tests, because the scratch directory cannot be emptied beforehand. This is addressed in agentvm mode by discarding any agents using that scratch directory and starting new agents using a new empty scratch directory. Successive directives use suffices _1, _2, etc. If you see such directories appearing in the work directory, that is an indication that files were left open in the preceding directory in the series. Locking support Some tests use shared system resources such as fixed port numbers. This causes a problem when running tests concurrently. So, you can now mark a directory such that all the tests within all such directories will be run sequentially, even if you use -concurrency:N on the command line to run the rest of the tests in parallel. This is seen as a short term solution: it is recommended that tests not use shared system resources whenever possible. If you are running multiple instances of jtreg on the same machine at the same time, you can use a new option -lock:file to specify a file to be used for file locking; otherwise, the locking will just be within the JVM used to run jtreg. "autovm mode" By default, if no options to the contrary are given on the command line, tests will be run in othervm mode. Now, a test suite can be marked so that the default execution mode is "agentvm" mode. In conjunction with this, you can now mark a directory such that all the tests within that directory will be run in "othervm" mode. Conceptually, this is equivalent to putting /othervm on every appropriate action on every test in that directory and any subdirectories. This is seen as a short term solution: it is recommended tests be adapted to use agentvm mode, or use "@run main/othervm" explicitly. Info in test result files The user name and jtreg version info are now stored in the properties near the beginning of the .jtr file. Build The makefiles used to build and test jtreg have been reorganized and simplified. jtreg is now using JT Harness version 4.4. Other jtreg provides access to GNOME_DESKTOP_SESSION_ID when set. jtreg ensures that shell tests are given an absolute path for the JDK under test. jtreg now honors the "first sentence rule" for the description given by @summary. jtreg saves the default locale before executing a test in samevm or agentvm mode, and restores it afterwards. Bug fixes jtreg tried to execute a test even if the compilation failed in agentvm mode because of a JVM crash. jtreg did not correctly handle the -compilejdk option. Acknowledgements Thanks to Alan, Amy, Andrey, Brad, Christine, Dima, Max, Mike, Sherman, Steve and others for their help, suggestions, bug reports and for testing this latest version.

How do I deal with a third party application that has embedded hints that result in a sub-optimal execution plan in my environment?

- by Maria Colgan

I have gotten many variations on this question recently as folks begin to upgrade to Oracle Database 11g and there have been several posts on this blog and on others describing how to use SQL Plan Management (SPM) so that a non-hinted SQL statement can use a plan generated with hints. But what if the hint is supplied in the third party application and is causing performance regressions on your system? You can actually use a very similar technique to the ones shown before but this time capture the un-hinted plan and have the hinted SQL statement use that plan instead. Below is an example that demonstrates the necessary steps. 1. We will begin by running the hinted statement 2. After examining the execution plan we can see it is suboptimal because of a bad join order. 3. In order to use SPM to correct the problem we must create a SQL plan baseline for the statement. In order to create a baseline we will need the SQL_ID for the hinted statement. Easy place to get it is in V$SQL. 4. A SQL plan baseline can be created using a SQL_ID and DBMS_SPM.LOAD_PLANS_FROM_CURSOR_CACHE. This will capture the existing plan for this SQL_ID from the shared pool and store in the SQL plan baseline. 5. We can check the SQL plan baseline got created successfully by querying DBA_SQL_PLAN_BASELINES. 6. When you manually create a SQL plan baseline the first plan added is automatically accepted and enabled. We know that the hinted plan is poorly performing plan so we will disable it using DBMS_SPM.ALTER_SQL_PLAN_BASELINE. Disabling the plan tells the optimizer that this plan not a good plan, however since there is no alternative plan at this point the optimizer will still continue to use this plan until we provide a better one. 7. Now let's run the statement without the hint. 8. Looking at the execution plan we can see that the join order is different. The plan without the hint also has a lower cost (3X lower), which indicates it should perform better. 9. In order to map the un-hinted plan to the hinted SQL statement we need to add the plan to the SQL plan baseline for the hinted statement. We can do this using DBMS_SPM.LOAD_PLANS_FROM_CURSOR_CACHE but we will need the SQL_ID and PLAN_HASH_VALUE for the non-hinted statement, which we can find in V$SQL. 10. Now we can add the non-hinted plan to the SQL plan baseline of the hinted SQL statement using DBMS_SPM.LOAD_PLANS_FROM_CURSOR_CACHE. This time we need to pass a few more arguments. We will use the SQL_ID and PLAN_HASH_VALUE of the non-hinted statement but the SQL_HANDLE of the hinted statement. 11. The SQL plan baseline for our statement now has two plans. But only the newly added plan (SQL_PLAN_gbpcg3f67pc788a6d8911) is enabled and accepted. This tells the Optimizer that this is the plan it should use for this statement. We can confirm that the correct plan (non-hinted) will be selected for the statement from now on by re-executing the hinted statement and checking its execution plan.

Weblogic 10.3.4 (PS3) nodemanager wont start?

- by angelo.santagata

Hi all, well Im back from Australia and one of the things which happened was Oracle announced the PS3 release of oracles SOA & Webcenter products have been released. Now I normally use pre-installed images but I always like to install the products at least once that way I get to see its installation caveats.. Here’s one. Installation on Windows 7 64bit, 64bit JVM, generic weblogic Server installer. All worked fine, EXCEPT I cant start the node manager, I get the following error <08-Feb-2011 17:16:48> <INFO> <Loading domains file: D:\products\wls1034\WLSERV~1.3\common\NODEMA~1\nodemanager.domains> <08-Feb-2011 17:16:48> <SEVERE> <Fatal error in node manager server> weblogic.nodemanager.common.ConfigException: Native version is enabled but nodemanager native library could not be loaded at weblogic.nodemanager.server.NMServerConfig.initProcessControl(NMServerConfig.java:249) at weblogic.nodemanager.server.NMServerConfig.<init>(NMServerConfig.java:190) at weblogic.nodemanager.server.NMServer.init(NMServer.java:182) at weblogic.nodemanager.server.NMServer.<init>(NMServer.java:148) at weblogic.nodemanager.server.NMServer.main(NMServer.java:390) at weblogic.NodeManager.main(NodeManager.java:31) Caused by: java.lang.UnsatisfiedLinkError: D:\products\wls1034\wlserver_10.3\server\native\win\32\nodemanager.dll: Can't load IA 32-bit .dll on a AMD 64-bit platform at java.lang.ClassLoader$NativeLibrary.load(Native Method) at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1803) at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1728) at java.lang.Runtime.loadLibrary0(Runtime.java:823) at java.lang.System.loadLibrary(System.java:1028) at weblogic.nodemanager.util.WindowsProcessControl.<init>(WindowsProcessControl.java:17) at weblogic.nodemanager.util.ProcessControlFactory.getProcessControl(ProcessControlFactory.java:24) at weblogic.nodemanager.server.NMServerConfig.initProcessControl(NMServerConfig.java:247) ... 5 more Ok it appears that the node manager has gotten confused and thinks this is a 32bit install of Weblogic Server whereas it is the 64bit install.. Might have been something I did, or didnt do, on installation (e.g. –d64 on the jvm command line), however the workaround is pretty easy. 1. Create a file called nodemanager.properties in %WL_HOME%\common\nodemanager on my machine it was D:\products\wls1034\wlserver_10.3\common\nodemanager 2. Add the following line to it NativeVersionEnabled=false 3. And start it up!, this will force it not to use .DLL files and use emulation/non native methods instead..

My Doors - Why Standards Matter to Business

- by Brian Dayton

"Standards save money." "Standards accelerate projects." "Standards make better solutions." What do these statements mean to you? You buy technology solutions like Oracle Applications but you're a business person--trying to close the quarter, get performance reviews processed, negotiate a new sourcing contract, etc. When "standards" come up in presentations and discussions do you: - Nod your head politely - Tune out and check your smart phone - Turn to your IT counterpart and say "Bob's all over this standards thing, right Bob?" Here's why standards matter. My wife wants new external doors downstairs, ones that would get more light into the rooms. Am I OK with that? "Uhh, sure...it's a little dark in the kitchen." - 24 hours ago - wife calls to tell me that she's going to the hardware store and may look at doors - 20 hours ago - wife pulls into driveway, informs me that two doors are in the back of her station wagon, ready for me to carry - 19 hours ago - I re-discovered the fact that it's not fun to carry a solid wood door by myself - 5 hours ago - Local handyman, who was at our house anyway, tells me that the doors we bought will likely cost 2-3x the material cost in installation time and labor...the doors are standard but our doorways aren't We could have done more research. I could be more handy. Sure. But the fact is, my 1951 house wasn't built with me in mind. They built what worked and called it a day. The same holds true with a lot of business applications. They were designed and architected for one-time use with one use-case in mind. Today's business climate is different. If you're going to use your processes and technology to differentiate your business you should have at least a working knowledge of: - How standards can benefit your business - Your IT organization's philosophy around standards - Your vendor's track-record around standards...and watch for those who pay lip-service to standards but don't follow through The rallying cry in most IT organizations today is "learn more about the business, drop the acronyms." I'm not advocating that you go out and learn how to code in Java. But I do believe it will help your business and your decision-making process if you meet IT ½...even ¼ of the way there. Epilogue: The door project has been put on hold and yours truly has to return the doors to the hardware store tomorrow.

Chrome Web Browser Messages: Some Observations

- by ultan o'broin

I'm always on the lookout for how different apps handle errors and what kind of messages are shown (I probably need to get out more), I use this 'research' to reflect on our own application error messages patterns and guidelines and how we might make things better for our users in future. Users are influenced by all sorts of things, but their everyday experiences of technology, and especially what they encounter on the internet, increasingly sets their expectations for the enterprise user experience too. I recently came across a couple of examples from Google's Chrome web browser that got me thinking. In the first case, we have a Chrome error about not being able to find a web page. I like how simple, straightforward messaging language is used along with an optional ability to explore things a bit further--for those users who want to. The 'more information' option shows the error encountered by the browser (or 'original' error) in technical terms, along with an error number. Contrasting the two messages about essentially the same problem reveals what's useful to users and what's not. Everyone can use the first message, but the technical version of the message has to be explicitly disclosed for any more advanced user to pursue further. More technical users might search for a resolution, using that Error 324 number, but I imagine most users who see the message will try again later or check their URL again. Seems reasonable that such an approach be adopted in the enterprise space too, right? Maybe. Generally, end users don't go searching for solutions based on those error numbers, and help desk folks generally prefer they don't do so. That's because of the more critical nature of enterprise data or the fact that end users may not have the necessary privileges to make any fixes anyway. What might be more useful here is a link to a trusted source of additional help provided by the help desk or reputable community instead. This takes me on to the second case, this time more closely related to the language used in messaging situations. Here, I first noticed by the using of the (s) approach to convey possibilities of there being one or more pages at the heart of the problem. This approach is a no-no in Oracle style terms (the plural would be used) and it can create translation issues (though it is not a show-stopper). I think Google could have gone with the plural too. However, of more interest is the use of the verb "kill", shown in the message text and as an action button label. For many writers, words like "kill" and "abort" are to be avoided as they can give offense. I am not so sure about that judgment, as really their use cannot be separated from the context. Certainly, for more technical users, they're fine and have been in use for years, so I see no reason to avoid these terms if the audience has accepted them. Most end users too, I think would find the idea of "kill" usable and may even use the term in every day speech. Others might disagree--Apple uses a concept of Force Quit, for example. Ultimately, the only way to really know how to proceed is to research these matter by asking users of differing roles and expertise to perform some tasks, encounter these messages and then make recommendations based on those findings for our designs. Something to do in 2011!

Hidden exceptions

- by user12617285

Occasionally you may find yourself in a Java application environment where exceptions in your code are being caught by the application framework and either silently swallowed or converted into a generic exception. Either way, the potentially useful details of your original exception are inaccessible. Wouldn't it be nice if there was a VM option that showed the stack trace for every exception thrown, whether or not it's caught? In fact, HotSpot includes such an option: -XX:+TraceExceptions. However, this option is only available in a debug build of HotSpot (search globals.hpp for TraceExceptions). And based on a quick skim of the HotSpot source code, this option only prints the exception class and message. A more useful capability would be to have the complete stack trace printed as well as the code location catching the exception. This is what the various TraceException* options in in Maxine do (and more). That said, there is a way to achieve a limited version of the same thing with a stock standard JVM. It involves the use of the -Xbootclasspath/p non-standard option. The trick is to modify the source of java.lang.Exception by inserting the following: private static final boolean logging = System.getProperty("TraceExceptions") != null; private void log() { if (logging && sun.misc.VM.isBooted()) { printStackTrace(); } } Then every constructor simply needs to be modified to call log() just before returning: public Exception(String message) { super(message); log(); } public Exception(String message, Throwable cause) { super(message, cause); log(); } // etc... You now need to compile the modified Exception.java source and prepend the resulting class to the boot class path as well as add -DTraceExceptions to your java command line. Here's a console session showing these steps: % mkdir boot % javac -d boot Exception.java % java -DTraceExceptions -Xbootclasspath/p:boot -cp com.oracle.max.vm/bin test.output.HelloWorld java.util.zip.ZipException: error in opening zip file at java.util.zip.ZipFile.open(Native Method) at java.util.zip.ZipFile.(ZipFile.java:127) at java.util.jar.JarFile.(JarFile.java:135) at java.util.jar.JarFile.(JarFile.java:72) at sun.misc.URLClassPath$JarLoader.getJarFile(URLClassPath.java:646) at sun.misc.URLClassPath$JarLoader.access$600(URLClassPath.java:540) at sun.misc.URLClassPath$JarLoader$1.run(URLClassPath.java:607) at java.security.AccessController.doPrivileged(Native Method) at sun.misc.URLClassPath$JarLoader.ensureOpen(URLClassPath.java:599) at sun.misc.URLClassPath$JarLoader.(URLClassPath.java:583) at sun.misc.URLClassPath$3.run(URLClassPath.java:333) at java.security.AccessController.doPrivileged(Native Method) at sun.misc.URLClassPath.getLoader(URLClassPath.java:322) at sun.misc.URLClassPath.getLoader(URLClassPath.java:299) at sun.misc.URLClassPath.getResource(URLClassPath.java:168) at java.net.URLClassLoader$1.run(URLClassLoader.java:194) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at sun.misc.Launcher$ExtClassLoader.findClass(Launcher.java:229) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at java.lang.ClassLoader.loadClass(ClassLoader.java:295) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:247) java.security.PrivilegedActionException at java.security.AccessController.doPrivileged(Native Method) at sun.misc.URLClassPath$JarLoader.ensureOpen(URLClassPath.java:599) at sun.misc.URLClassPath$JarLoader.(URLClassPath.java:583) at sun.misc.URLClassPath$3.run(URLClassPath.java:333) at java.security.AccessController.doPrivileged(Native Method) at sun.misc.URLClassPath.getLoader(URLClassPath.java:322) ... It's worth pointing out that this is not as useful as direct VM support for tracing exceptions. It has (at least) the following limitations: The trace is shown for every exception, whether it is thrown or not. It only applies to subclasses of java.lang.Exception as there appears to be bootstrap issues when the modification is applied to Throwable.java. It does not show you where the exception was caught. It involves overriding a class in rt.jar, something should never be done in a non-development environment.

Countdown of Top 10 Reasons to Never Ever Use a Pie Chart

- by Tony Wolfram

Pie charts are evil. They represent much of what is wrong with the poor design of many websites and software applications. They're also innefective, misleading, and innacurate. Using a pie chart as your graph of choice to visually display important statistics and information demonstrates either a lack of knowledge, laziness, or poor design skills. Figure 1: A floating, tilted, 3D pie chart with shadow trying (poorly)to show usage statistics within a graphics application. Of course, pie charts in and of themselves are not evil. This blog is really about designers making poor decisions for all the wrong reasons. In order for a pie chart to appear on a web page, somebody chose it over the other alternatives, and probably thought they were doing the right thing. They weren't. Using a pie chart is almost always a bad design decision. Figure 2: Pie Chart from an Oracle Reports User Guide A pie chart does not do the job of effectively displaying information in an elegant visual form. Being circular, they use up too much space while not allowing their labels to line up. Bar charts, line charts, and tables do a much better job. Expert designers, statisticians, and business analysts have documented their many failings, and strongly urge software and report designers not to use them. It's obvious to them that the pie chart has too many inherent defects to ever be used effectively. Figure 3: Demonstration of how comparing data between multiple pie charts is difficult. Yet pie charts are still used frequently in today's software applications, financial reports, and websites, often on the opening page as a symbol of how the data inside is represented. In an attempt to get a flashy colorful graphic to break up boring text, designers will often settle for a pie chart that looks like pac man, a colored spinning wheel, or a 3D floating alien space ship. Figure 4: Best use of a pie chart I've found yet. Why is the pie chart so popular? Through its constant use and iconic representation as the classic chart, the idea persists that it must be a good choice, since everyone else is still using it. Like a virus or an urban legend, no amount of vaccine or debunking will slow down the use of pie charts, which seem to be resistant to logic and common sense. Even the new iPad from Apple showcases the pie chart as one of its options. Figure 5: Screen shot of new iPad showcasing pie charts. Regardless of the futility in trying to rid the planet of this often used poor design choice, I now present to you my top 10 reasons why you should never, ever user a pie chart again. Number 10 - Pie Charts Just Don't Work When Comparing Data Number 9 - You Have A Better Option: The Sorted Horizontal Bar Chart Number 8 - The Pie Chart is Always Round Number 7 - Some Genius Will Make It 3D Number 6 - Legends and Labels are Hard to Align and Read Number 5 - Nobody Has Ever Made a Critical Decision Using a Pie Chart Number 4 - It Doesn't Scale Well to More Than 2 Items Number 3 - A Pie Chart Causes Distortions and Errors Number 2 - Everyone Else Uses Them: Debunking the "Urban Legend" of Pie Charts Number 1 - Pie Charts Make You Look Stupid and Lazy

JCP Awards 10 Year Retrospective

- by Heather VanCura

As we celebrate 10 years of JCP Program Award recognition in 2012, take a look back in the Retrospective article covering the history of the JCP awards. Most recently, the JCP awards were celebrated at JavaOne Latin America in Brazil, where SouJava was presented the JCP Member of the Year Award for 2012 (won jointly with the London Java Community) for their contributions and launch of the Global Adopt-a-JSR Program. This is also a good time to honor the JCP Award Nominees and Winners who have been designated as Star Spec Leads. Spec Leads are key to the Java Community Process (JCP) program. Without them, none of the Java Specification Requests (JSRs) would have begun, much less completed and become implemented in shipping products. Nominations for 2012 Start Spec Leads are now open until 31 December. The Star Spec Lead program recognizes Spec Leads who have repeatedly proven their merit by producing high quality specifications, establishing best practices, and mentoring others. The point of such honor is to endorse the good work that they do, showcase their methods for other Spec Leads to emulate, and motivate other JCP program members and participants to get involved in the JCP program. Ed Burns – A Star Spec Lead for 2009, Ed first got involved with the JCP program when he became co-Spec Lead of JSR 127, JavaServer Faces (JSF), a role he has continued through JSF 1.2 and now JSF 2.0, which is JSR 314. Linda DeMichiel – Linda thus involved in the JCP program from its very early days. She has been the Spec Lead on at least three JSRs and an EC member for another three. She holds a Ph.D. in Computer Science from Stanford University. Gavin King – Nominated as a JCP Outstanding Spec Lead for 2010, for his work with JSR 299. His endorsement said, “He was not only able to work through disputes and objections to the evolving programming model, but he resolved them into solutions that were more technically sound, and which gained support of its pundits.” Mike Milikich – Nominated for his work on Java Micro Edition (ME) standards, implementations, tools, and Technology Compatibility Kits (TCKs), Mike was a 2009 Star Spec Lead for JSR 271, Mobile Information Device Profile 3. David Nuescheler – Serving as the CTO for Day Software, acquired by Adobe Systems, David has been a key player in the growth of the company’s global content management solution. In 2002, he became Spec Lead for JSR 170, Content Repository for Java Technology API, continuing for the subsequent version, JSR 283. Bill Shannon – A well-respected name in the Java community, Bill came to Oracle from Sun as a Distinguished Engineer and is still performing at full speed as Spec Lead for JSR 342, Java EE 7, as an alternate EC member, and hands-on problem solver for the Java community as a whole. Jim Van Peursem – Jim holds a PhD in Computer Engineering. He was part of the Motorola team that worked with Sun labs on the Spotless VM that became the KVM. From within Motorola, Jim has been responsible for many aspects of Java technology deployment, from an independent Connected Limited Device Configuration (CLDC) and Mobile Information Device Profile (MIDP) implementations, to handset development, to working with the industry in defining many related standards. Participation in the JCP Program goes well beyond technical proficiency. The JCP Awards Program is an attempt to say “Thank You” to all of the JCP members, Expert Group Members, Spec Leads, and EC members who give their time to contribute to the evolution of Java technology.

2014 Conferences - JFokus, JavaLand & GeeCon!

- by Heather VanCura

There has been a delay in publishing these past event summaries from early 2014--JFokus in February, JavaLand in March, and GeeCon in May. As we plan for Devoxx UK next week, I found these summaries that did not make it past 'draft' stage. We had some great successes with the first three events of 2014, a Java developer conference trifecta! Participation topics included Java, the JCP program overall and the Adopt-a-JSR programs. First up in February was JFokus in Stockholm. The energy and talent in Stockholm is amazing and the conference organizers do a stellar job running it and welcoming the speakers of this event. I enjoyed the city walk and speaker dinner, as well as many opportunities to interact with conference speakers and attendees, both during and after the conference hours. Reza Rehman invited me to speak during his Java EE 7 lab session about the Adopt-a-JSR program, and I gave a quickie session on the JCP and Adopt-a-JSR. There was also a late night Birds of a Feather (BoF) session held jointly with Cecelia Borg, Martijn Verburg and Reza Rehman. This was an interactive conversation with a focus on the Java EE community survey results and encouraging more community participation and collaboration in Java development. The Java 8 keynote by Georges Saab and Mark Reinhold was also very entertaining, I was sorry to miss FOSDEM happening the previous weekend this year in Brussels, but I hope to attend in 2015. Favorite take home gift -- Lambdas cap! In March, the inaugural version of the JavaLand conference happened inside Phantasialand, an amusement park in Germany. Markus Eisele suggested having an Early Adopters area at the conference, which I was keen to implement. In 2013 at Devoxx Belgium we held some activities in the Hackergaren area around Lambdas and Java EE 7, so this was a great opportunity to expand on a more interactive conference format and Andreas Badelt from the program committee helped in the planning for this area. Daniel Bryant and Mani Sarkar from the London Java Community led some general Adopt-a-JSR discussions and AdoptOpen JDK activities. JCP Spec Leads, Anatole Tresch from Credit Suisse, leading JSR 354, Money & Currency API, and Ed Burns from Oracle, leading JSR 344, JavaServer Faces 2.2, attended to engage with conference attendees on their JSRs. Favorite - Stephen Chin's roller coaster video. In May, GeeCon in Krakow was anther awesome conference! The conference organizers were warm and welcoming and I enjoyed time getting to know the other speakers at the event. There was a JCP and Adopt-a-JSR participation session as well as a moderated panel session on Early Adopters. We had an amazing panel -- Daniel Bryant, Arun Gupta, Tomasz Borek , and Peter Lawrey. The panel discussed the Adopt-a-JSR and Adopt OpenJDK program, and how the participants work together to get involved and contribute to both the Java SE and Java EE platforms. If was an interesting discussion and sparked some new ideas on how Java User Groups in Poland and around the world can contribute in a significant and meaningful way to create better and more practical Java standards today and in the future. Favorite take home gift - GeeCon mug! These were some of the highlights of the events--looking forward to Devoxx UK next week. I will publish these details tomorrow!

OEG11gR2 integration with OES11gR2 Authorization with condition

- by pgoutin

Introduction This OES use-case has been defined originally by Subbu Devulapalli (http://accessmanagement.wordpress.com/). Based on this OES museum use-case, I have developed the OEG11gR2 policy able to deal with the OES authorization with condition. From an OEG point of view, the way to deal with OES condition is to provide with the OES request some Environmental / Context Attributes. Museum Use-Case All painting in the museum have security sensors, an alarm goes off when a person comes too close a painting. The employee designated for maintenance needs to use their ID and disable the alarm before maintenance. You are the Security Administrator for the museum and you have been tasked with creating authorization policies to manage authorization for different paintings. Your first task is to understand how paintings are organized. Asking around, you are surprised to see that there isno formal process in place, so you need to start from scratch. the museum tracks the following attributes for each painting 1. Name of the work 2. Painter 3. Condition (good/poor) 4. Cost You compile the list of paintings Name of Painting Painter Paint Condition Cost Mona Lisa Leonardo da Vinci Good 100 Magi Leonardo da Vinci Poor 40 Starry Night Vincent Van Gogh Poor 75 Still Life Vincent Van Gogh Good 25 Being a software geek who doesn’t (yet) understand art, you feel that price(or insurance price) of a painting is the most important criteria. So you feel that based on years-of-experience employees can be tasked with maintaining different paintings. You decide that paintings worth over 50 cost should be only handled by employees with over 20 years of experience and employees with less than 10 years of experience should not handle any painting. Lets us start with policy modeling. All paintings have a common set of attributes and actions, so it will be good to have them under a single Resource Type. Based on this resource type we will create the actual resources. So our high level model is: 1) Resource Type: Painting which has action manage and the following four attributes a) Name of the work b) Painter c) Condition (good/poor) d) Cost 2) To keep things simple lets use painting name for Resource name (in real world you will try to use some identifier which is unique, because in future we may end up with more than one painting which has the same name.) 3) Create Resources based on the previous table 4) Create an identity attribute Experience (Integer) 5) Create the following authorization policies a) Allow employees with over 20 years experience to access all paintings b) Allow employees with 10 – 20 years of experience to access painting which cost less than 50 c) Deny access to all paintings for employees with less than 10 year of experience OES Authorization Configuration We do need to create 2 authorization policies with specific conditions a) Allow employees with over 20 years experience to access all paintings b) Allow employees with 10 – 20 years of experience to access painting which cost less than 50 c) Deny access to all paintings for employees with less than 10 year of experience We don’t need an explicit policy for Deny access to all paintings for employees with less than 10 year of experience, because Oracle Entitlements Server will automatically deny if there is no matching policy. OEG Policy The OEG policy looks like the following The 11g Authorization filter configuration is similar to : The ${PAINTING_NAME} and ${USER_EXPERIENCE} variables are initialized by the "Retrieve from the HTTP header" filters for testing purpose. That's to say, under Service Explorer, we need to provide 2 attributes "Experience" & "Painting" following the OES 11g Authorization filter described above.

Lease Accounting Closed for Comment

- by Theresa Hickman

December 15, 2010 marked the last day to send public comments to FASB and IASB on lease accounting. June 2011 is the deadline for the final consideration of the Leases Exposure Draft that will be given to standard setters in order to create a new lease accounting standard. Landlords, lessees, retailers, airlines industry, etc. are all worried right now about the changes to lease accounting. They feel the changes will be too costly and complex without adding significant improvement to the quality and relevance of financial statements. In a nutshell, IASB and FASB want to abolish operating leases where the lessee records the periodic payments as an expense over time. The proposed changes will mean that the accounting for leases will move from the P&L and hit both the lessee's and lessor's balance sheets. For companies that occupy a lot of property, this could significantly increase their liabilities not to mention front-load much of the costs that they were able to spread out over time before. Why are IASB and FASB doing this? Their goal is to have consistent accounting for both the lessees and lessors with higher quality financial statements. Leasing is one of four major projects being undertaken by the IASB and FASB in order to complete convergence between US GAAP and IFRS. I spoke to our resident accounting expert Seamus Moran about this to better understand how this might impact accounting software. He reminded me that the proposed changes to both US GAAP and IFRS in respect to leases are "proposed." It is still inappropriate to account for leases the way they are being proposed and we still need to account for them in accordance to the current regulations, which is what current accounting software programs, such as E-Business Suite Release 12.1 and prior and PeopleSoft Enterprise support. The FASB (US GAAP) and IASB (IFRS) exposure drafts (EDs) that outline the proposal were published. The FASB edition was published on August 17th, with comments due by December 15th. The IASB edition was published on the same date, and comments were due in London on the same date. Exposure drafts are the method both the FASB and the IASB use to solicit General Acceptance, the "GA" in GAAP. Both Boards will consider the input they have received, and perhaps revise the proposal. The proposal has come in for some criticism, both from the finance houses and the uses of the leased assets. There is, given the opposition to it, an excellent chance that the Leasing proposal will be modified or rewritten. We will know this in about six months, the usual time it takes for the FASB and IASB to digest the comments they receive. If they feel the proposal has General Acceptance, they will issue the final Standard at that time; if not, they will issue a revised proposal with another year of comment of drafting. Oracle participates in the standard setting process and is fully aware of the leasing proposal. We have designs that would reflect the proposal in hand. These designs will be finalized when the proposal is finalized. It is likely that customers will develop new financial arrangements if the proposal is finalized, and we are working with customers and partners to stay in touch with people's business responses to the proposal. The IASB and FASB are aware that ERP companies will have to revise their software, and that the companies filing results under IFRS or under US GAAP will have to implement such software. The form and timing of the release of the updated software will depend on the schedule of the take up of the new standard, the complexity of the standard, and the releases supported at the time the standard becomes effective.

Social Technology and the Potential for Organic Business Networks

- by Michael Snow

Guest Blog Post by: Michael Fauscette, IDCThere has been a lot of discussion around the topic of social business, or social enterprise, over the last few years. The concept of applying emerging technologies from the social Web, combined with changes in processes and culture, has the potential to provide benefits across the enterprise over a wide range of operations impacting employees, customers, partners and suppliers. Companies are using social tools to build out enterprise social networks that provide, among other things, a people-centric collaborative and knowledge sharing work environment which over time can breakdown organizational silos. On the outside of the business, social technology is adding new ways to support customers, market to prospects and customers, and even support the sales process. We’re also seeing new ways of connecting partners to the business that increases collaboration and innovation. All of the new "connectivity" is, I think, leading businesses to a business model built around the concept of the network or ecosystem instead of the old "stand-by-yourself" approach. So, if you think about businesses as networks in the context of all of the other technical and cultural change factors that we're seeing in the new information economy, you can start to see that there’s a lot of potential for co-innovation and collaboration that was very difficult to arrange before. This networked business model, or what I've started to call “organic business networks,” is the business model of the information economy.The word “organic” could be confusing, but when I use it in this context, I’m thinking it has similar traits to organic computing. Organic computing is a computing system that is self-optimizing, self-healing, self-configuring, and self-protecting. More broadly, organic models are generally patterns and methods found in living systems used as a metaphor for non-living systems.Applying an organic model, organic business networks are networks that represent the interconnectedness of the emerging information business environment. Organic business networks connect people, data/information, content, and IT systems in a flexible, self-optimizing, self-healing, self-configuring, and self-protecting system. People are the primary nodes of the network, but the other nodes — data, content, and applications/systems — are no less important.A business built around the organic business network business model would incorporate the characteristics of a social business, but go beyond the basics—i.e., use social business as the operational paradigm, but also use organic business networks as the mode of operating the business. The two concepts complement each other: social business is the “what,” and the organic business network is the “how.”An organic business network lets the business work go outside of traditional organizational boundaries and become the continuously adapting implementation of an optimized business strategy. Value creation can move to the optimal point in the network, depending on strategic influencers such as the economy, market dynamics, customer behavior, prospect behavior, partner behavior and needs, supply-chain dynamics, predictive business outcomes, etc.An organic business network driven company is the antithesis of a hierarchical, rigid, reactive, process-constrained, and siloed organization. Instead, the business can adapt to changing conditions, leverage assets effectively, and thrive in a hyper-connected, global competitive, information-driven environment.To hear more on this topic – I’ll be presenting in the next webcast of the Oracle Social Business Thought Leader Webcast Series - “Organic Business Networks: Doing Business in a Hyper-Connected World” this coming Thursday, June 21, 2012, 10:00 AM PDT – Register here

My Dog, Cross-Channel Shopping, and Fusion SCM

- by Kathryn Perry

A guest post by Mark Carson, Director, Oracle Fusion Supply Chain Management I was walking my dog Max in an open space behind my house. As we tromped through the tall weeds I remembered it is tick season and that I should get Max some protection. While he sniffed merrily in the tick infested brush, I started shopping in the middle of an open field on my phone. I thought it would be convenient to pick up the tick medicine from a pet store on the way home. Searching the pet store website I saw that they had the medicine, but there was no information on whether the store had any in stock and there were no options for shipping it to the store for pickup. I could return it, but not pick it up which seamed kind of odd. I really didn't feel like making calls to the local stores to find out if they had it. Since the product is popular, I tried one of the large 'everything' stores. Browsing its website I could see that it could be shipped to me, shipped to the store for free, and that the store nearest to me had it in stock. Needless to say, this store became a better option. This experience is a small example of why retailers, distributors, and manufactures have placed a high priority on enabling 'cross-channel commerce.' Shoppers like you and me expect to be able to search, compare, buy and return products on-line and over the phone using a variety of devices including PDAs, tablets and in-store kiosks. The pet store lost my business because its web channel had limited information about its stores. I have spoken with many customers and prospects about cross-channel commerce. They all realize the business implications and urgency behind cross-channel commerce but recognize there are challenges to enable it. New and existing applications must be integrated together globally through a consistent cross-channel business process. Integration is required between applications that provide the initial shopping experience and delivery applications associated with warehouses, stores, and partners. The enablement must be accomplished in a flexible way to react to fast-changing product portfolios and new acquisitions, while at the same time minimizing costs through reuse of existing systems. Meanwhile, the business must continue to grow and decision makers need to balance new capability with peak seasons. The challenges above are not unique to retail. Any customer in any industry who has multiple points for capturing orders and multiple points for fulfilling orders will face these challenges. With this in mind, we had a unique opportunity in Fusion SCM to re-think how to build a set of modular and flexible applications in the order management space that would make these challenges easier to conquer. The results are Fusion Distributed Order Orchestration and Global Order Promising. These applications can help companies, such as the pet store, enable true cross-channel commerce. The apps provide highly adaptable and flexible business processes to automate order orchestration across multiple cross-channel systems. They also show a global view of supply across warehouses, stores, and partners for real-time availability and more accurate order promising. Additional capability includes a standards-based integration framework for seamless execution and the ability to reuse existing systems for faster and lower cost implementations. OK, that was a mouthful of features and benefits. As Max waited to cross the street (he can do basic math too), I wondered if he could relate. He does not care about leash laws, pick-up courtesy, where he can/can't walk, what time of day it is, or even ticks. He does not care about how all these things could make walking complicated. He just wants to walk. Similarly, customers just want to shop and companies just want to make it easier to sell and deliver. You can learn more about Distributed Order Orchestration and Global Order Promising in cross-channel here.

HPCM 11.1.2.2.x - HPCM Standard Costing Generating >99 Calc Scipts

- by Jane Story

HPCM Standard Profitability calculation scripts are named based on a documented naming convention. From 11.1.2.2.x, the script name = a script suffix (1 letter) + POV identifier (3 digits) + Stage Order Number (1 digit) + “_” + index (2 digits) (please see documentation for more information (http://docs.oracle.com/cd/E17236_01/epm.1112/hpm_admin/apes01.html). This naming convention results in the name being 8 characters in length i.e. the maximum number of characters permitted calculation script names in non-unicode Essbase BSO databases. The index in the name will indicate the number of scripts per stage. In the vast majority of cases, the number of scripts generated per stage will be significantly less than 100 and therefore, there will be no issue. However, in some cases, the number of scripts generated can exceed 99. It is unusual for an application to generate more than 99 calculation scripts for one stage. This may indicate that explicit assignments are being extensively used. An assessment should be made of the design to see if assignment rules can be used instead. Assignment rules will reduce the need for so many calculation script lines which will reduce the requirement for such a large number of calculation scripts. In cases where the scripts generates exceeds 100, the length of the name of the 100th calculation script is different from the 99th as the calculation script name changes from being 8 characters long and becomes 9 characters long (e.g. A6811_100 rather than A6811_99). A name of 9 characters is not permitted in non Unicode applications. It is “too long”. When this occurs, an error will show in the hpcm.log as “Error processing calculation scripts” and “Unexpected error in business logic “. Further down the log, it is possible to see that this is “Caused by: Error copying object “ and “Caused by: com.essbase.api.base.EssException: Cannot put olap file object ... object name_[<calc script name> e.g. A6811_100] too long for non-unicode mode application”. The error file will give the name of the calculation script which is causing the issue. In my example, this is A6811_100 and you can see this is 9 characters in length. It is not possible to increase the number of characters allowed in a calculation script name. However, it is possible to increase the size of each calculation script. The default for an HPCM application, set in the preferences, is set to 4mb. If the size of each calculation script is larger, the number of scripts generated will reduce and, therefore, less than 100 scripts will be generated which means that the name of the calculation script will remain 8 characters long. To increase the size of the generated calculation scripts for an application, in the HPM_APPLICATION_PREFERENCE table for the application, find the row where HPM_PREFERENCE_NAME_ID=20. The default value in this row is 4194304. This can be increased e.g. 7340032 will increase this to 7mb. Please restart the profitability service after making the change.

Two Candidates + One Job = Two Different Outcomes

- by david.talamelli

Recruiters have always headhunted (sidenote: I do not like this word, in general I think the type of people who use the phrase “headhunting” are the ones who are trying to sound more important than what they likely are). Any serious Recruiter engages in direct recruiting activity, it is part and parcel of the business it is not something unique. With the uptake in Social Media the past 4-5 years, we have seen an increase in the number of Recruiters proactively reaching out to people about job opportunities. We have also seen this activity increase across all levels of hire, from help desk roles to C-Level Executives. While getting approached about a role can be a nice boost to a person’s ego, do not let it give you an inflated sense of entitlement. It is The way that people handle themselves during these calls and subsequent interviews will have a large impact on their potential to land that job. Last week I spoke to two very different candidates, both about the same position and both with very different outcomes. On paper, Candidate #1 looked fantastic; they ticked many of the boxes that we were looking for. The person is working at global IT company and working in a similar role as the one we were hiring for but not in as senior as the role we had. This role would have been the perfect step to getting involved in more complex work for the person. Candidate #2 had less polished IT experience, ticked some of the boxes we were looking for and on paper in comparison to Candidate #1 was not as close a fit as Candidate #1 was. It seemed like I was comparing apples and oranges. After speaking to both candidates it turns out I was comparing apples and oranges except the person better suited for our role was not the one I was expecting it would be. The first candidate on paper looked great – they had the experience we were looking for and appeared to be just right for the role, but after talking to them, they gave me the impression that they thought the world owed them. The impression I was left with was that they did not equate success with hard work, they seemed more interested in “what is in it for me”. Rather than having a proper conversation with me, I was often cut off and asked to hurry it up when explaining our business, what we are doing, etc... . This person seemed more interested in the job title and money than how rather than think about ways to make the role successful. Candidate #2 who had limited experience, made up for any perceived lack of experience and them some with a demonstrated motivation to succeed and do the things needed to make that happen. Candidate #2 made a great first impression, they did not seem afraid of hard work and demonstrated a “team player” attitude. In talking to them they kept me engaged, listened and asked thoughtful questions that made me think this is the type of person who creates their own luck and who would thrive in a place like Oracle. Skills, capabilities, experience and a good resume can certainly get your foot in the door, but the wrong attitude or approach to work can close those opportunities just as easily. On the other hand, hard work, effort and a genuine work ethic may help open those doors that would otherwise closed for you. A resume with all the credentials gets you in the front door but that is just the beginning of the process. It is not how we start the race that is important, it’s how things end that matter most.

Wisdom Lies in Collaborative Power and Intelligence

- by kellsey.ruppel

By Alakh Verma, Director, Platform Technology Solutions In my recent blog posts, I shared insights on Predictive Analytics (Will Predictive Analytics at 'Speed of Thoughts' Help Businesses?), Real Time Decisions (How critical are Real Time decisions in business today?) and their significance in our lives in general and in businesses today. In the current business paradigm shift- with evolutionary social business, it is paramount that businesses look for wisdom in collaborative power and intelligence and equip their employees with the tools to engage with one another. There is an old time saying that 5 sticks tied together are stronger and unable to break as opposed to an individual stick. We have recently witnessed the power of ordinary people uniting together and fought collaboratively using Facebook and Twitter to topple down dictators in Tunisia, Egypt and Libya—and are threatening absolute rule in Syria. And an India one man’s (Anna Hazare) campaign against corruption went viral, bringing thousands to the streets in support. As anyone who has worked in a sizeable organization knows, there is no guarantee that the organization as a whole will perform efficiently and achieve its goals, even if each employee is individually efficient and every team has a high level of productivity. To achieve enterprise productivity, it is necessary not only for individuals and groups to “do things right” by working productively but also for the enterprise as a whole to “do the right things” - form the right teams, make the right decisions, allocate resources correctly, and effectively coordinate activities across the entire organization. Most organizations fall short of the optimal level of enterprise productivity because of one or more of these reasons, all at a great cost to the business. They are disconnected from themselves with various parts of the organization unintentionally working at cross-purposes with each other. Information that exists is not getting shared or reused. Human talent is not being applied where it is most needed. The same problems are being solved repeatedly by multiple groups. Intelligent collaboration through automated business processes has the ability to alter the course of any important business activity, with a potentially dramatic impact on the financial performance of the business. Whether it is a simple email exchange, a physical or virtual meeting, a task force, or a large-scale project, the activity is inherently collaborative. In fact, collaboration can be defined as the work that takes place among people when a business process is not pre-determining how the work should take place. Collaboration is many things: information sharing, brainstorming, problem solving, best practice negotiation, innovation, coordination of activity, alignment of purpose, and so forth. Collaboration is the “white space” between the business processes; it is the glue that holds an organization together, and the lubricant that allows the machinery to keep running. Real time search and collaborative capabilities of the right people with the right content supported by defined processes will provide unparallel wisdom in the organization in the most competitive business environment today. Interestingly, technologies such as Oracle WebCenter offer these capabilities in our Web based business transactions and compliment in the overall collaborative intelligence and power to truly transform organizations to social businesses.

How to deploy global managed beans

Global managed beans contain helper - or utility - methods like or instead of JSFUtils and ADFUtils. The difference between global managed beans and static helper classes like JSFUtis and ADFUtils is that they are EL accessible, providing reusable functionality that is ready to use on UI components and - if accessed from Java - in other managed beans. For example, the ADF Faces page template (af:pageTemplate) allows you to define attributes for the consuming page to pass in object references or strings into it. It does not have method attributes that allow command components contained in a template to invoke listeners in managed beans and the ADF binding layer, or to execute actions. To create templates that provide global button or menu functionality, like logon, logout, print etc., an option for developers is to deployed managed beans with the ADF Faces page templates. To deploy a managed bean with a page template, create an ADF library from the project containing the template definition and import this ADF library into the target project using the Resource palette. When importing an ADF library, all its content is added to the project, including page template definitions, managed bean sources and configurations. More about page templates http://download.oracle.com/docs/cd/E17904_01/apirefs.1111/e12419/tagdoc/af_pageTemplate.html Another use-case for globally configured managed beans is for creating helper methods to be used in many applications. Instead of creating a base managed bean class that then is extended by all managed beans used in applications, you can deploy a managed bean in a JAR file and add the faces-config.xml file with the managed bean configuration to the JAR's META-INF folder as shown below. Using a globally configured managed bean allows you to use Expression Language in the UI to access common functionality but also use Java in application specific managed beans. Storing the faces-config.xml file in the JAR file META-INF directory automatically makes it available when the JAR file is found in the class path of an application.

Session Sharing with another User on *NIX and Windows

- by Giri Mandalika

Oracle Solaris Since Solaris is not widely known for its graphical interface, let's just focus on sharing a terminal session in read-only mode with another user on the same system. Here is an example. eg., % finger Login Name TTY Idle When Where root Super-User pts/1 Sat 16:57 dhcp-amer-vpn-rmdc-a sunperf ??? pts/2 4 Sat 16:41 pitcher.sfbay.sun.com In this example, two users root and sunperf are connected to the same system from two different terminals pts/1 and pts/2 respectively. If the root user wants to show something to sunperf user -- what s/he is doing in her/his terminal, for example, it can be accomplished with the following command. script -a /dev/null | tee -a <target_terminal eg., # script -a /dev/null | tee -a /dev/pts/2 Script started, file is /dev/null # # uptime 5:04pm up 1 day(s), 2:56, 2 users, load average: 0.81, 0.81, 0.81 # # isainfo -v 64-bit sparcv9 applications crc32c cbcond pause mont mpmul sha512 sha256 sha1 md5 camellia kasumi des aes ima hpc vis3 fmaf asi_blk_init vis2 vis popc 32-bit sparc applications crc32c cbcond pause mont mpmul sha512 sha256 sha1 md5 camellia kasumi des aes ima hpc vis3 fmaf asi_blk_init vis2 vis popc v8plus div32 mul32 # # exit Script done, file is /dev/null After the script .. | tee .. command, sunperf user should be able to see the root user's stdin and stdout contents in her/his own terminal until the script session exits in root user's terminal. Since this kind of sharing is based on capturing and redirecting the contents to the target terminal, the users on the receiving end won't be able to see whatever is being edited on initiators' terminal [using editors such as vi]. Also it is not possible to share the session with any connected user on the system unless the initiator has the necessary permissions and privileges. The script utility records everything printed in a terminal session, while the tee utility replicates the contents of the screen capture on to the standard output of the target terimal. The tee utility does not buffer the output - so, the screen capture from the initiators' terminal appears almost right away in the target terminal. Though I never tested, this technique may work on all *NIX and Linux flavors with little or no changes. Also there might be other ways to accomplish this. [Thanks to Sujeet for sharing this tip] Microsoft Windows Most of the Windows users may rely on VNC services to share a desktop session. Another way to share the desktop session is to use the Remote Desktop Connection (RDC) client. Here are the steps. Connect to the target Windows system using Remote Desktop Connection client Launch Windows Task Manager Navigate to the "Users" tab Find the user session that you want to connect to and have full control over as the other user who is currently holding that session Select the user name in Windows Task Manager, right click and choose the option "Remote Control" A window pops up on the other user's session with the message "<USER is requesting to control your session remotely. Do you accept the request?" Once the other user says "Yes", you will be granted access to that session. Since then both users should be able to see the same screen and even control the session from their respective workstations.

Process Power to the People that Create Engagement

- by Michael Snow

Organizations often speak about their engagement problems as if the problem is the people they are trying to engage - employees, partners, customers and citizens. The reality of most engagement problems is that the processes put in place to engage are impersonal, inflexible, unintuitive, and often completely ignorant of the population they are trying to serve. Life, Liberty and the Pursuit of Delight? How appropriate during this short week of the US Independence Day Holiday that we're focusing on People, Process and Engagement. As we celebrate this holiday in the US and the historic independence we gained (sorry Brits!) - it's interesting to think back to 1776 to the creation of that pivotal document, the Declaration of Independence. What tremendous pressure to create an engaging document and founding experience they must have felt. "On June 11, 1776, in anticipation of the impending vote for independence from Great Britain, the Continental Congress appointed five men — Thomas Jefferson, John Adams, Benjamin Franklin, Roger Sherman, and Robert Livingston — to write a declaration that would make clear to people everywhere why this break from Great Britain was both necessary and inevitable. The committee then appointed Jefferson to draft a statement. Jefferson produced a "fair copy" of his draft declaration, which became the basic text of his "original Rough draught." The text was first submitted to Adams, then Franklin, and finally to the other two members of the committee. Before the committee submitted the declaration to Congress on June 28, they made forty-seven emendations to the document. During the ensuing congressional debates of July 1-4, 1776, Congress adopted thirty-nine further revisions to the committee draft. (http://www.constitution.org) If anything was an attempt for engaging the hearts and minds of the 13 Colonies at the time, this document certainly succeeded in its mission. ...Their tools at the time were pen and ink and parchment. Although the final document would later be typeset with lead type for a printing press to distribute to the colonies, all of the original drafts were hand written. And today's enterprise complains about using "Review and Track Changes" at times. Can you imagine the manual revision control process? or lack thereof? Collaborative process? Time delays? Would implementing a better process have helped our founding fathers collaborate better? Declaration of Independence rough draft below. One of many during the creation process. Great comparison across multiple versions of the document here. (from http://www.ushistory.org/): While you may not be creating a new independent nation, getting your employees to engage is crucial to your success as a company in today's world. Oracle WebCenter provides the tools that power engagement. Employees that have better tools for communication, collaboration and getting their job done are more engaged employees. Better engaged employees create more engaged customers and partners. 12.00 Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 -"/ /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman","serif"; mso-fareast-font-family:"Times New Roman";}

It happens only at Devoxx ...

- by arungupta

After attending several Java conferences world wide, this was my very first time at Devoxx. Here are some items I found that happens only at Devoxx ... Pioneers of theater-style seating - This not only provides comfortable seating for each attendee but the screens are very clearly visible to everybody in the room. Intellectual level of attendees is very high - Read more explanation on the Java EE 6 lab blog. In short, a lab, 1/3 of the content delivered at Devoxx 2011, could not be completed at other developer days in more than 1/3 the time. Snack box for lunches - Even though this suits well to the healthy lifestyle of multiple-snacks-during-a-day style but leaves attendees hungry sooner in the day. The longer breaks before the next snack in the evening does not help at all. Fortunately, Azure cupcakes and Android ice creams turned out to be handy. I finally carried my own apple :-) Wrist band instead of lanyard - The good part about this is that once tied to your hand then you are less likely to forget in your room. But OTOH you are a pretty much a branded conference attendee all through out the city. It was cost effective as it costed 20c as opposed to 1 euro for the lanyard. Live streaming from theater #8 (the biggest room) on parleys.com All talks recorded and released on parleys.com over next year. This allows attendees to not to miss any session and watch replay at their own leisure. Stephan promised to start sharing the sessions by mid December this year. No need to pre-register for a session - This is true for most of the conferences but bigger rooms (+ overflow room for key sessions) provide sufficient space for all those who want to attend the session. And of course all sessions are available on parleys.com anyway! Community votes on whiteboard - Devoxx attendees gets a chance to vote on topics ranging from their favorite non-Java language, operating system, or love from Oracle. Captured pictures at the end of Day 2 are shown below. Movie on the last but one night - This year it was The Adventures of Tintin and was lots of fun. Fries with mayo - This is a typical Belgian thing. Guys going in ladies room to avoid the long queues ... wow! Tweet wall everywhere and I mean literally everywhere, in rooms, hallways, front desk, and other places. The tweet picking algorithm was not very clear as I never saw my tweet appear on the wall ;-) You can also watch it at wall.devoxx.com. Cozy speaker dinner with great food and wine List of parallel and upcoming sessions displayed on the screen - This makes the information more explicit with the attendees. REST API with multiple mobile clients - This API is also used by some other conferences as well. And there always is iphone.devoxx.com. Steering committee members were recognized multiple times. The committee members were clearly identifiable wearing red hoodies. The wireless SSID was intuitive "Devoxx" but hidden to avoid some crap from Microsoft Windows. All of 9000 addresses were used up most of the times with each attendee having multiple devices. A 1 GB fibre optic cable was stretched to Metropolis to support the required network bandwidth. Stephan is already planning to upgrade the equipment and have a better infrastructure next year. Free water, soda, juice in a cooler Kinect connected to TV screens so that attendees can use their hands to browse through the list of sesssions. #devoxxblog, #devoxxwomen, #devoxxfrance, #devoxxgreat, #devoxxsuggestions And Devoxx attendees are called Devoxxians ... how cool is that ? :-) What other things do you think happen only at Devoxx ? And now the pictures from the community whiteboard: And a more complete album (including bigger pics of community votes) is available below:

The Connected Company: WebCenter Portal - Feedback - Analytics and Polls

- by Michael Snow

Evernote Export body, td { }Guest Post by: Mitchell Palski, Staff Sales Consultant The importance of connecting peers has been widely recognized and socialized as a critical component of employee intranets. Organizations are striving to provide mediums for sharing knowledge and improving awareness across their enterprise. Indirectly, the socialization of your enterprise should lead to cost savings and improved product/service quality. However, many times the direct effects of connecting an organization’s leadership with its employees are overlooked. Oracle WebCenter Portal can help you bridge that gap by gathering implicit and explicit feedback. Implicit Feedback Through Usage Analytics Analytics allows administrators to track and analyze WebCenter Portal traffic and usage. Analytics provides the following basic functionality: Usage Tracking Metrics: Analytics collects and reports metrics of common WebCenter Portal functions, including community and portlet traffic. Behavior Tracking: Analytics can be used to analyze WebCenter Portal metrics to determine usage patterns, such as page visit duration and usage over time. User Profile Correlation: Analytics can be used to correlate metric information with user profile information. Usage tracking reports can be viewed and filtered by user profile data such as country, company or title. Usage analytics help measure how users interact with website content – allowing your IT staff and business analysts to make informed decisions when planning development for your next intranet enhancement. For example: If users are not accessing your Announcements page and missing critical information that they need to be aware of, you may elect to use graphical links on the home page to direct more users to that page. As a result, the number of employee help-requests to HR decreases. If users are not accessing your News page to read recent articles, you may elect to stop spending as much time updating the page with new stories and cut costs in your communications department. You notice that there is a high volume of users accessing the Employee Dashboard page so your organization decides to continue making personalization enhancements to the page and investing in the Portal tool that most users are accessing. Usage analytics aren’t necessarily a new concept in the IT industry. What sets WebCenter Portal Analytics apart is: Reports are tailored for WebCenter specific tools Report can be easily added to a page as simple as a drag-and-drop Explicit Feedback Through Polls WebCenter Portal users can create, edit, take, and analyze online polls. With polls, you can survey your audience (such as their opinions and their experience level), check whether they can recall important information, and gather feedback and metrics. How many times have you been involved in a requirements discussion and someone has asked a question similar to “Well how do you know that no one likes our home page?” and the response is “Everyone says they hate it! That’s all anyone complains about.” No one has any measurable, quantifiable metric to gauge user satisfaction. Analytics measure usage, but your organization also needs to measure the quality of your portal as defined by the actual people that use it. With that information, your leadership can make informed decisions that will not only match usage patterns but also relate to employees on a personal level. The end result is a connection between employees and leadership that gives everyone in the organization a sense of ownership of their Portal rather than the feeling of development decisions being segregated to leadership only. Polls can be created and edited through the Poll Manager: Polls and View Poll Results can easily be added to a page through drag-and-drop. What did we learn? Being a “connected” company doesn’t just mean helping employees connect with each other horizontally across your enterprise. It also means connecting those employees to the decisions that affect their everyday activities. Through WebCenter Portal Usage Analytics and Polls, any decision that is made to remove a Portal page, update a Portal page, or develop new Portal functionality, can be justified by quantifiable metrics. Instead of fielding complaints and hearing that your employees don’t have a voice, give those employees a voice and listen!

Observing flow control idle time in TCP

- by user12820842

Previously I described how to observe congestion control strategies during transmission, and here I talked about TCP's sliding window approach for handling flow control on the receive side. A neat trick would now be to put the pieces together and ask the following question - how often is TCP transmission blocked by congestion control (send-side flow control) versus a zero-sized send window (which is the receiver saying it cannot process any more data)? So in effect we are asking whether the size of the receive window of the peer or the congestion control strategy may be sub-optimal. The result of such a problem would be that we have TCP data that we could be transmitting but we are not, potentially effecting throughput. So flow control is in effect: when the congestion window is less than or equal to the amount of bytes outstanding on the connection. We can derive this from args[3]-tcps_snxt - args[3]-tcps_suna, i.e. the difference between the next sequence number to send and the lowest unacknowledged sequence number; and when the window in the TCP segment received is advertised as 0 We time from these events until we send new data (i.e. args[4]-tcp_seq = snxt value when window closes. Here's the script: #!/usr/sbin/dtrace -s #pragma D option quiet tcp:::send / (args[3]-tcps_snxt - args[3]-tcps_suna) = args[3]-tcps_cwnd / { cwndclosed[args[1]-cs_cid] = timestamp; cwndsnxt[args[1]-cs_cid] = args[3]-tcps_snxt; @numclosed["cwnd", args[2]-ip_daddr, args[4]-tcp_dport] = count(); } tcp:::send / cwndclosed[args[1]-cs_cid] && args[4]-tcp_seq = cwndsnxt[args[1]-cs_cid] / { @meantimeclosed["cwnd", args[2]-ip_daddr, args[4]-tcp_dport] = avg(timestamp - cwndclosed[args[1]-cs_cid]); @stddevtimeclosed["cwnd", args[2]-ip_daddr, args[4]-tcp_dport] = stddev(timestamp - cwndclosed[args[1]-cs_cid]); @numclosed["cwnd", args[2]-ip_daddr, args[4]-tcp_dport] = count(); cwndclosed[args[1]-cs_cid] = 0; cwndsnxt[args[1]-cs_cid] = 0; } tcp:::receive / args[4]-tcp_window == 0 && (args[4]-tcp_flags & (TH_SYN|TH_RST|TH_FIN)) == 0 / { swndclosed[args[1]-cs_cid] = timestamp; swndsnxt[args[1]-cs_cid] = args[3]-tcps_snxt; @numclosed["swnd", args[2]-ip_saddr, args[4]-tcp_dport] = count(); } tcp:::send / swndclosed[args[1]-cs_cid] && args[4]-tcp_seq = swndsnxt[args[1]-cs_cid] / { @meantimeclosed["swnd", args[2]-ip_daddr, args[4]-tcp_sport] = avg(timestamp - swndclosed[args[1]-cs_cid]); @stddevtimeclosed["swnd", args[2]-ip_daddr, args[4]-tcp_sport] = stddev(timestamp - swndclosed[args[1]-cs_cid]); swndclosed[args[1]-cs_cid] = 0; swndsnxt[args[1]-cs_cid] = 0; } END { printf("%-6s %-20s %-8s %-25s %-8s %-8s\n", "Window", "Remote host", "Port", "TCP Avg WndClosed(ns)", "StdDev", "Num"); printa("%-6s %-20s %-8d %@-25d %@-8d %@-8d\n", @meantimeclosed, @stddevtimeclosed, @numclosed); } So this script will show us whether the peer's receive window size is preventing flow ("swnd" events) or whether congestion control is limiting flow ("cwnd" events). As an example I traced on a server with a large file transfer in progress via a webserver and with an active ssh connection running "find / -depth -print". Here is the output: ^C Window Remote host Port TCP Avg WndClosed(ns) StdDev Num cwnd 10.175.96.92 80 86064329 77311705 125 cwnd 10.175.96.92 22 122068522 151039669 81 So we see in this case, the congestion window closes 125 times for port 80 connections and 81 times for ssh. The average time the window is closed is 0.086sec for port 80 and 0.12sec for port 22. So if you wish to change congestion control algorithm in Oracle Solaris 11, a useful step may be to see if congestion really is an issue on your network. Scripts like the one posted above can help assess this, but it's worth reiterating that if congestion control is occuring, that's not necessarily a problem that needs fixing. Recall that congestion control is about controlling flow to prevent large-scale drops, so looking at congestion events in isolation doesn't tell us the whole story. For example, are we seeing more congestion events with one control algorithm, but more drops/retransmission with another? As always, it's best to start with measures of throughput and latency before arriving at a specific hypothesis such as "my congestion control algorithm is sub-optimal".

Essbase BSO Data Fragmentation

- by Ann Donahue

Essbase BSO Data Fragmentation Data fragmentation naturally occurs in Essbase Block Storage (BSO) databases where there are a lot of end user data updates, incremental data loads, many lock and send, and/or many calculations executed. If an Essbase database starts to experience performance slow-downs, this is an indication that there may be too much fragmentation. See Chapter 54 Improving Essbase Performance in the Essbase DBA Guide for more details on measuring and eliminating fragmentation: http://docs.oracle.com/cd/E17236_01/epm.1112/esb_dbag/daprcset.html Fragmentation is likely to occur in the following situations: Read/write databases that users are constantly updating data Databases that execute calculations around the clock Databases that frequently update and recalculate dense members Data loads that are poorly designed Databases that contain a significant number of Dynamic Calc and Store members Databases that use an isolation level of uncommitted access with commit block set to zero There are two types of data block fragmentation Free space tracking, which is measured using the Average Fragmentation Quotient statistic. Block order on disk, which is measured using the Average Cluster Ratio statistic. Average Fragmentation Quotient The Average Fragmentation Quotient ratio measures free space in a given database. As you update and calculate data, empty spaces occur when a block can no longer fit in its original space and will either append at the end of the file or fit in another empty space that is large enough. These empty spaces take up space in the .PAG files. The higher the number the more empty spaces you have, therefore, the bigger the .PAG file and the longer it takes to traverse through the .PAG file to get to a particular record. An Average Fragmentation Quotient value of 3.174765 means the database is 3% fragmented with free space. Average Cluster Ratio Average Cluster Ratio describes the order the blocks actually exist in the database. An Average Cluster Ratio number of 1 means all the blocks are ordered in the correct sequence in the order of the Outline. As you load data and calculate data blocks, the sequence can start to be out of order. This is because when you write to a block it may not be able to place back in the exact same spot in the database that it existed before. The lower this number the more out of order it becomes and the more it affects performance. An Average Cluster Ratio value of 1 means no fragmentation. Any value lower than 1 i.e. 0.01032828 means the data blocks are getting further out of order from the outline order. Eliminating Data Block Fragmentation Both types of data block fragmentation can be removed by doing a dense restructure or export/clear/import of the data. There are two types of dense restructure: 1. Implicit Restructures Implicit dense restructure happens when outline changes are done using EAS Outline Editor or Dimension Build. Essbase restructures create new .PAG files restructuring the data blocks in the .PAG files. When Essbase restructures the data blocks, it regenerates the index automatically so that index entries point to the new data blocks. Empty blocks are NOT removed with implicit restructures. 2. Explicit Restructures Explicit dense restructure happens when a manual initiation of the database restructure is executed. An explicit dense restructure is a full restructure which comprises of a dense restructure as outlined above plus the removal of empty blocks Empty Blocks vs. Fragmentation The existence of empty blocks is not considered fragmentation. Empty blocks can be created through calc scripts or formulas. An empty block will add to an existing database block count and will be included in the block counts of the database properties. There are no statistics for empty blocks. The only way to determine if empty blocks exist in an Essbase database is to record your current block count, export the entire database, clear the database then import the exported data. If the block count decreased, the difference is the number of empty blocks that had existed in the database.
