  • XBRL US Conference Highlights

    - by john.orourke(at)oracle.com
    Back in early November I had an opportunity to attend the XBRL US National Conference in Philadelphia.  At the event, XBRL US announced that Oracle had joined the initiative, so I had a chance to participate in a press conference and attend a number of sessions.  Oracle joined XBRL US so we can stay ahead of the standard and leverage it in our products, and to help drive awareness with customers and improve adoption of XBRL. There were roughly 250 attendees at the event, about half of which were vendors and consultants and the rest financial reporting staff from corporate filers.  Event sponsors included Ernst & Young, SWIFT and Fujitsu.  There were also a number of XBRL technology and service providers exhibiting at the conference.  On Monday Nov. 8th, the XBRL US Steering Committee meetings and Annual Members meeting and reception were held.  At the Annual Members meeting the big news was that current XBRL US President, Mark Bolgiano, is moving to a new position at Howard Hughes Medical Center.  Campbell Pryde, who had led the Taxonomy Development for XBRL US, is taking over as XBRL US President. Other items that were highlighted at the members meeting included: The US GAAP XBRL taxonomy is being used by over 1500 SEC filers and has now been handed over to the FASB to maintain and enhance 16 filer training events were held in 2010 XBRL Global Magazine was launched Corporate Actions proposal was submitted to the SEC with SWIFT in May XBRL Labs for iPhone, XBRL US Consistency Suite launched ISO 2022 Corporate Actions Alignment with XBRL achieved The XBRL Credit Rating taxonomy was accepted Tuesday Nov. 9th included Keynotes, General Sessions, Innovation Workshop for Governments and Securities Professionals, and an Opening Reception.  General sessions included: Lessons Learned from the SEC's rollout of XBRL.  More than 18,000 errors were identified in reviews of filings between June 2009 and September 2010.  Most of these related to negative values being used where they shouldn't have.  Also, the SEC feels there are too many taxonomy extensions being created - mostly in the Cash Flow Statements.  They emphasize using existing elements in the US GAAP taxonomy and advise filers not to  create extensions to improve the visual formatting of XBRL filings. Investors and XBRL - Setting the Standard for Data Quality.  In this panel discussion, the key learning was that CFA's, academics and the financial community are not using XBRL as expected.  The issues raised include the  accuracy and completeness of filings, number of taxonomy extensions, and limited number of tools available to help analyze XBRL data.  Another big issue that was raised is the lack of historic results in XBRL - most analysts need 10 quarters of historic data.  On the positive side, XBRL has the potential to eliminate re-keying of data and errors here and can improve analytic capabilities for financial analysts once more historic data is available and more companies are providing detailed tagging of their filings. A US Roadmap for XBRL Financial Reporting.  This was a panel discussion featuring Jeff Neumann(SEC), Campbell Pryde(XBRL US), and Louis Matherne(FASB).  Key points included the fact that XBRL is currently used by 1500 companies, with 8000 more companies coming in 2011.  XBRL for Mutual Fund Reporting will start in 2011 for 8000 funds, and a Credit Rating Taxonomy has now been submitted for review.  The XBRL tagging/filing process is improving each quarter - more education is helping here.  The FASB is looking at extensions to date, and potential additions to US GAAP taxonomy, while the SEC is evaluating filings for accuracy, consistency in tagging, and tools for analyzing data.  The big news is that the FASB 2011 US GAAP Taxonomy has been completed and reviewed by SEC.  The 2011 US GAAP Taxonomy supports new FASB accounting standards issued since 2009, has new taxonomy elements for certain industries (i.e airlines) and the elimination of 500 concepts.  (meaning they can't be used going forward but are still supported for historical comparison)  The 2011 US GAAP Taxonomy will be available for usage with Q2 2011 SEC filings.  More information about this can be found on the FASB web site.  http://www.fasb.org/home Accounting Firms and XBRL.  This session covered the Role of Audit Firms, which includes awareness and education, validation of XBRL filings, and in-house transition planning.  The main advice provided was that organizations should document XBRL mapping process, perform peer comparisons, and risk assessments on a regular basis. Wednesday Nov. 10th included more Keynotes, General Sessions on Corporate Actions, and XBRL Essentials Workshop Training for corporate filers.  The XBRL Essentials Training included: Getting Started Once you Have the Basics Detailed Footnote Tagging and Handling Tables Quality Control and Trust in the XBRL Process Bringing XBRL In-House:  What are the Options, What should you consider? The US GAAP Financial Reporting Taxonomy - Overview of the 2011 release The XBRL Essentials Training was well-attended with about 80 people.  This included a good overview of the SEC's XBRL mandate, limited liability issue, tagging levels, recommended planning process, internal vs. outsourced approach, and how to manage service providers.  I learned a lot from the session on detailed tagging.  This is the requirement that kicks in during a company's second year of XBRL filing with the SEC and applies to financial statements, footnotes and disclosures (it does not apply to MD&A, executive communications and other information).  The review of the Linkbase model, or dimensional table structure, was very interesting and can be complex to understand.  The key takeaway here is that using dimensional tables in XBRL filings can help limit the number of taxonomy extensions that are required.  The slides from this session are posted on the XBRL US web site. (http://xbrl.us/events/Pages/archive.aspx) For me, the main summary points and takeaways from the XBRL US conference are: XBRL for financial reporting has turned the corner and gone mainstream - with 1500 companies currently using it and 8000 more coming in 2011 The expected value is not being achieved by filers or consumers of XBRL data - this will improve when more companies are filing in XBRL, more history is available, and more software tools are available for analysis (hmm, sounds like an opportunity for Oracle) XBRL is becoming the global standard for all business communications beyond just the financials - i.e. adoption for mutual funds, corporate actions and others planned for the future If you would like to learn more about XBRL and the various training programs, services and software tools that are available check out the XBRL US web site and even better - become a member.  Here's a link:  http://xbrl.us/Pages/default.aspx

  • SQL Developer: Describe versus Ctrl+Click to Open Database Objects

    - by thatjeffsmith
    In yesterday’s post I talked about you could use SQL Developer’s Describe (SHIFT+F4) to open a PL/SQL Package at your cursor. You might get an error if you try to describe this… If you actually try to describe the package as you see it in the above screenshot, you’ll get an error: Doh! I neglected to say in yesterday’s post that I was highlighting the package name before I hit SHIFT+F4. This works just fine, but it will work even better in our next release as we’ve fixed this issue. Until then, you can also try the Ctrl+Hover with your mouse. For PL/SQL calls you can open the source immediately based on what you’re hovering over with your mouse cursor. You could try this with “dbms_output.put_line(” too Ctrl+Click, It’s not just for PL/SQL If you don’t like the floating describe windows you get when you do a SHIFT+F4 on a database object, the ctrl+click will work too. Instead of opening a normal ‘hover’ panel, you’ll be taken directly to the object editor for that table, view, etc. Go ahead and try it right now. Paste this into your worksheet, then ctrl+click with your mouse over the table name: select * from scott.emp And now you know, the rest of the story.

  • E-Business Integration with SSO using AccessGate

    - by user774220
    Moving away from the legacy Oracle SSO, Oracle E-Business Suite (EBS) came up with EBS AccessGate as the way forward to provide Single Sign On with Oracle Access Manager (OAM). As opposed to AccessGate in OAM terminology, EBS AccessGate has no specific connection with OAM with respect to configuration. Instead, EBS AccessGate uses the header variables sent from the SSO system to create the native user-session, like any other SSO enabled web application. E-Business Suite Integration with Oracle Access Manager It is a known fact that E-Business suite requires Oracle Internet Directory (OID) as the user repository to enable Single Sign On. This is due to the fact that E-Business Suite needs to be registered with OID to for Single Sign On. Additionally, E-Business Suite uses “orclguid” in OID to map the Single Sign On user with the corresponding local user profile. During authentication, EBS AccessGate expects SSO system to return orclguid and EBS username (stored as a user-attribute in SSO user store) in two header variables USER_ORCLGUID and USER_NAME respectively. Following diagram depicts the authentication flow once SSO system returns EBS Username and orclguid after successful authentication: Topic to brainstorm: EBS AccessGate as a generic SSO enablement solution for E-Business Suite AccessGate Even though EBS AccessGate is suggested as an integration approach between OAM and Oracle E-Business Suite, this section attempts to look at EBS AccessGate as a generic solution approach to provide SSO to Oracle E-Business Suite using any Web SSO solution. From the above points, the only dependency on the SSO system is that it should be able to return the corresponding orclguid from the OID which is configured with the E-Business Suite. This can be achieved by a variety of approaches: By using the same OID referred by E-Business Suite as the Single Sign On user store. If SSO System is using a different user store then: Use DIP or OIM to synch orclsguid from E-Business Suite OID to SSO user store Use OVD to provide an LDAP view where orclguid from E-Business Suite OID is part of the user entity in the user store referred by SSO System

  • Windows Azure Evolution &ndash; Deploy Web Sites (WAWS Part 3)

    - by Shaun
    This is the sixth post of my Windows Azure Evolution series. After talked a bit about the new caching preview feature in the previous one, let’s back to the Windows Azure Web Sites (WAWS).   Git and GitHub Integration In the third post I introduced the overview functionality of WAWS and demonstrated how to create a WordPress blog through the build-in application gallery. And in the fourth post I covered how to use the TFS service preview to deploy an ASP.NET MVC application to the web site through the TFS integration. WAWS also have the Git integration. I’m not going to talk very detailed about the Git and GitHub integration since there are a bunch of information on the internet you can refer to. To enable the Git just go to the web site item in the developer portal and click the “Set up Git publishing”. After specified the username and password the windows azure platform will establish the Git integration and provide some basic guide. As you can see, you can download the Git binaries, commit the files and then push to the remote repository. Regarding the GitHub, since it’s built on top of Git it should work. Maarten Balliauw have a wonderful post about how to integrate GitHub to Windows Azure Web Site you can find here.   WebMatrix 2 RC WebMatrix is a lightweight web application development tool provided by Microsoft. It utilizes WebDeploy or FTP to deploy the web application to the server. And in WebMatrix 2.0 RC it added the feature to work with Windows Azure. First of all we need to download the latest WebMatrix 2 through the Web Platform Installer 4.0. Just open the WebPI and search “WebMatrix”, or go to its home page download its web installer. Once we have WebMatrix 2, we need to download the publish file of our WAWS. Let’s go to the developer portal and open the web site we want to deploy and download the publish file from the link on the right hand side. This file contains the necessary information of publishing the web site through WebDeploy and FTP, which can be used in WebMatrix, Visual Studio, etc.. Once we have the publish file we can open the WebMatrix, click the Open Site, Remote Site. Then it will bring up a dialog where we can input the information of the remote site. Since we have our publish file already, we can click the “Import publish settings” and select the publish file, then we can see the site information will be populated automatically. Click OK, the WebMatrix will connect to the remote site, which is the WAWS we had deployed already, retrieve the folders and files information. We can open files in WebMatrix and modify. But since WebMatrix is a lightweight web application tool, we cannot update the backend C# code. So in this case, we will modify the frontend home page only. After saved our modification, WebMatrix will compare the files between in local and remote and then it will only upload the modified files to Windows Azure through the connection information in the publish file. Since it only update the files which were changed, this minimized the bandwidth and deployment duration. After few seconds we back to the website and the modification had been applied.   Visual Studio and WebDeploy The publish file we had downloaded can be used not only in WebMatrix but also Visual Studio. As we know in Visual Studio we can publish a web application by clicking the “Publish” item from the project context menu in the solution explorer, and we can specify the WebDeploy, FTP or File System for the publish target. Now we can use the WAWS publish file to let Visual Studio publish the web application to WAWS. Let’s create a new ASP.NET MVC Web Application in Visual Studio 2010 and then click the “Publish” in solution explorer. Once we have the Windows Azure SDK 1.7 installed, it will update the web application publish dialog. So now we can import the publish information from the publish file. Select WebDeploy as the publish method. We can select FTP as well, which is supported by Windows Azure and the FTP information was in the same publish file. In the last step the publish wizard can check the files which will be uploaded to the remote site before the actually publishing. This gives us a chance to review and amend the files. Same as the WebMatrix, Visual Studio will compare the files between local and WAWS and determined which had been changed and need to be published. Finally Visual Studio will publish the web application to windows azure through WebDeploy protocol. Once it finished we can browse our website.   FTP Deployment The publish file we downloaded contains the connection information to our web site via both WebDeploy and FTP. When using WebMatrix and Visual Studio we can select WebDeploy or FTP. WebDeploy method can be used very easily from WebMatrix and Visual Studio, with the file compare feature. But the FTP gives more flexibility. We can use any FTP client to upload files to windows azure regardless which client and OS we are using. Open the publish file in any text editor, we can find the connection information very easily. As you can see the publish file is actually a XML file with WebDeploy and FTP information in plain text attributes. And once we have the FTP URL, username and password, when can connect to the site and upload and download files. For example I opened FileZilla and connected to my WAWS through FTP. Then I can download files I am interested in and modify them on my local disk. Then upload back to windows azure through FileZilla. Then I can see the new page.   Summary In this simple and quick post I introduced vary approaches to deploy our web application to Windows Azure Web Site. It supports TFS integration which I mentioned previously. It also supports Git and GitHub, WebDeploy and FTP as well.   Hope this helps, Shaun All documents and related graphics, codes are provided "AS IS" without warranty of any kind.

  • 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..

  • An introductory presentation about testing with MSTest, Visual Studio, and Team Foundation Server 2010

    - by Thomas Weller
    While it was very quiet here on my blog during the last months, this was not at all true for the rest of my professional life. The simple story is that I was too busy to find the time for authoring blog posts (and you might see from my previous ones that they’re usually not of the ‘Hey, I’m currently reading X’ or ‘I’m currently thinking about Y’ kind…). Anyway. Among the things I did during the last months were setting up a TFS environment (2010) and introducing a development team to the MSTest framework (aka. Visual Studio Unit Testing), some additional tools (e.g. Moq, Moles, White),  how this is supported in Visual Studio, and how it integrates into the broader context of the then new TFS environment. After wiping out all the stuff which was directly related to my former customer and reviewing/extending the Speaker notes, I thought I share this presentation (via Slideshare) with the rest of the world. Hopefully it can be useful to someone else out there… Introduction to testing with MSTest, Visual Studio, and Team Foundation Server 2010 View more presentations from Thomas Weller. Be sure to also check out the slide notes (either by viewing the presentation directly on Slideshare or - even better - by downloading it). They contain quite some additional information, hints, and (in my opinion) best practices.

  • Talend Enterprise Data Integration overperforms on Oracle SPARC T4

    - by Amir Javanshir
    The SPARC T microprocessor, released in 2005 by Sun Microsystems, and now continued at Oracle, has a good track record in parallel execution and multi-threaded performance. However it was less suited for pure single-threaded workloads. The new SPARC T4 processor is now filling that gap by offering a 5x better single-thread performance over previous generations. Following our long-term relationship with Talend, a fast growing ISV positioned by Gartner in the “Visionaries” quadrant of the “Magic Quadrant for Data Integration Tools”, we decided to test some of their integration components with the T4 chip, more precisely on a T4-1 system, in order to verify first hand if this new processor stands up to its promises. Several tests were performed, mainly focused on: Single-thread performance of the new SPARC T4 processor compared to an older SPARC T2+ processor Overall throughput of the SPARC T4-1 server using multiple threads The tests consisted in reading large amounts of data --ten's of gigabytes--, processing and writing them back to a file or an Oracle 11gR2 database table. They are CPU, memory and IO bound tests. Given the main focus of this project --CPU performance--, bottlenecks were removed as much as possible on the memory and IO sub-systems. When possible, the data to process was put into the ZFS filesystem cache, for instance. Also, two external storage devices were directly attached to the servers under test, each one divided in two ZFS pools for read and write operations. Multi-thread: Testing throughput on the Oracle T4-1 The tests were performed with different number of simultaneous threads (1, 2, 4, 8, 12, 16, 32, 48 and 64) and using different storage devices: Flash, Fibre Channel storage, two stripped internal disks and one single internal disk. All storage devices used ZFS as filesystem and volume management. Each thread read a dedicated 1GB-large file containing 12.5M lines with the following structure: customerID;FirstName;LastName;StreetAddress;City;State;Zip;Cust_Status;Since_DT;Status_DT 1;Ronald;Reagan;South Highway;Santa Fe;Montana;98756;A;04-06-2006;09-08-2008 2;Theodore;Roosevelt;Timberlane Drive;Columbus;Louisiana;75677;A;10-05-2009;27-05-2008 3;Andrew;Madison;S Rustle St;Santa Fe;Arkansas;75677;A;29-04-2005;09-02-2008 4;Dwight;Adams;South Roosevelt Drive;Baton Rouge;Vermont;75677;A;15-02-2004;26-01-2007 […] The following graphs present the results of our tests: Unsurprisingly up to 16 threads, all files fit in the ZFS cache a.k.a L2ARC : once the cache is hot there is no performance difference depending on the underlying storage. From 16 threads upwards however, it is clear that IO becomes a bottleneck, having a good IO subsystem is thus key. Single-disk performance collapses whereas the Sun F5100 and ST6180 arrays allow the T4-1 to scale quite seamlessly. From 32 to 64 threads, the performance is almost constant with just a slow decline. For the database load tests, only the best IO configuration --using external storage devices-- were used, hosting the Oracle table spaces and redo log files. Using the Sun Storage F5100 array allows the T4-1 server to scale up to 48 parallel JVM processes before saturating the CPU. The final result is a staggering 646K lines per second insertion in an Oracle table using 48 parallel threads. Single-thread: Testing the single thread performance Seven different tests were performed on both servers. Given the fact that only one thread, thus one file was read, no IO bottleneck was involved, all data being served from the ZFS cache. Read File ? Filter ? Write File: Read file, filter data, write the filtered data in a new file. The filter is set on the “Status” column: only lines with status set to “A” are selected. This limits each output file to about 500 MB. Read File ? Load Database Table: Read file, insert into a single Oracle table. Average: Read file, compute the average of a numeric column, write the result in a new file. Division & Square Root: Read file, perform a division and square root on a numeric column, write the result data in a new file. Oracle DB Dump: Dump the content of an Oracle table (12.5M rows) into a CSV file. Transform: Read file, transform, write the result data in a new file. The transformations applied are: set the address column to upper case and add an extra column at the end, which is the concatenation of two columns. Sort: Read file, sort a numeric and alpha numeric column, write the result data in a new file. The following table and graph present the final results of the tests: Throughput unit is thousand lines per second processed (K lines/second). Improvement is the % of improvement between the T5140 and T4-1. Test T4-1 (Time s.) T5140 (Time s.) Improvement T4-1 (Throughput) T5140 (Throughput) Read/Filter/Write 125 806 645% 100 16 Read/Load Database 195 1111 570% 64 11 Average 96 557 580% 130 22 Division & Square Root 161 1054 655% 78 12 Oracle DB Dump 164 945 576% 76 13 Transform 159 1124 707% 79 11 Sort 251 1336 532% 50 9 The improvement of single-thread performance is quite dramatic: depending on the tests, the T4 is between 5.4 to 7 times faster than the T2+. It seems clear that the SPARC T4 processor has gone a long way filling the gap in single-thread performance, without sacrifying the multi-threaded capability as it still shows a very impressive scaling on heavy-duty multi-threaded jobs. Finally, as always at Oracle ISV Engineering, we are happy to help our ISV partners test their own applications on our platforms, so don't hesitate to contact us and let's see what the SPARC T4-based systems can do for your application! "As describe in this benchmark, Talend Enterprise Data Integration has overperformed on T4. I was generally happy to see that the T4 gave scaling opportunities for many scenarios like complex aggregations. Row by row insertion in Oracle DB is faster with more than 650,000 rows per seconds without using any bulk Oracle capabilities !" Cedric Carbone, Talend CTO.

  • Be Careful When Referencing SPList.Items

    - by Brian Jackett
    Be very careful how you reference your SPListItem objects through the SharePoint API.  I’ll say it again.  Be very careful how you reference your SPListItem objects through the SharePoint API.  Ok, now that you get the point that this will be a “learn from my mistakes and don’t do unsmart things like I did” post, let’s dig into what it was that I did poorly. Scenario     For the past year I’ve been building custom .Net applications that are hosted through SharePoint.  These application involve a number of SharePoint lists, external databases, custom web parts, and other SharePoint elements to provide functionality.  About two weeks ago I received a message from one of our end users that a custom application was performing slowly.  Specifically performance was slow when users were performing actions that interacted with the primary SharePoint list storing data for that app. The Problem     I took a copy of the production site into a dev environment to investigate the code that was executing.  After attaching the debugger and running through the code I quickly found pieces of code referencing SPListItem objects (like below) that were performing very poorly: SPListItem myItem = SPContext.Current.Web.Lists["List Name"].Items.GetItemById(value); // do updates on SPListItem retrieved     As it turns out the SPList I was referencing was fairly large at ~1000 items and weighing in over 150 MB.  You see the problem with my above code is that I retrieved the SPListItem by first (unnecessarily) going through the Items member of the list.  As I understand it, when doing so the executing code will attempt to resolve that entity and pull it from the database and into RAM (all 150 MB.)  This causes the equivalent of a 50 car pile up in terms of performance with a single update taking more than 15 seconds. The Solution     The solution is actually quite simple and I wish I had realized this during development.  Instead of going through the Items member it is possible to call GetItemById(…) directly on the SPList as in the example below: SPListItem myItem = SPContext.Current.Web.Lists["List Name"].GetItemById(value); // do updates on SPListItem retrieved     After making this simple change performance skyrocketed and updates were back to less than a second.   Conclusion     When given the option between two solutions, usually the simplest is the best solution.  In my scenario I was adding extra complexity going through the API the long way around to get to the objects I needed and it ended up hurting performance greatly.  Luckily we were able to find and resolve the performance issue in a relatively short amount of time.  Like I said at the beginning of the post, learn from my mistakes and hope it helps you.         -Frog Out   Image linked from http://www.freespirit.com/files/IMAGE/COVER/LARGE/BeCarefulSafe.jpg

  • SQL Azure Pricing

    - by kaleidoscope
    Microsoft’s pricing for SQL Server in the cloud, SQLAzure has been announced: $9.99   per month for 0 – 1GB $99.99 per month up to 10GB. There’s currently a 10GB maximum size cap for SQLAzure. For larger data storage needs, you’ll need to break the databases into smaller sizes. Scaling SQL Azure Applications If you think you’re going to need 100GB in the near term, it probably makes sense to break your application up into multiple separate databases from the get-go (10 x $9.99 = $99.99 anyway) and just make really sure none of the individual databases exceed 10GB. Beep Beep, Back That Database Up The bandwidth costs for SQL Azure are $.15 per GB of outbound bandwidth.  Assuming that you don’t compress the data before you pull it out of the cloud, that means daily backups of a 1GB database will add another $4.50 per month, and a 10GB database will add another $45/month.  Daily backups will cost about half of what your monthly service charges cost. It’s not completely clear from the press release, but if Microsoft follows Amazon’s pricing model, bandwidth between the Microsoft cloud services will not incur a cost.  That would mean it might make sense to spin up an Windows Azure computing application for $.12 per hour, use that application to compress your SQL Azure database, and then send the compressed data off to Azure storage for backup.  That would eliminate the data in/out costs, and minimize the Azure storage costs ($.15/GB).  Database administrators would back up their SQL Azure data to Azure Storage, keep a history of backups there, and restore them to SQL Azure faster when needed. Of course, there’s no native backup support in SQL Azure, and it’s not clear whether Windows Azure will include tools like SQL Server Integration Services.

  • Oracle Announces Availability of Oracle Exaskeleton with Extreme Scale

    - by Bruce Tierney
    The World’s First Human Scale Body Surface (HSBS) Designed to Toughen Spineless Wimps April 1, 2012 Building on the success of Oracle Exalogic, Oracle Exadata, and Oracle Exalytics, Oracle today announced the general availability of Oracle Exaskeleton, toughening up spineless wimps across the globe through the introduction of extreme scalability over the human body leveraging a revolutionary new technology called Human Scale Body Surface (HSBS). First Customer Ship (FCS) was received by the little known and mostly unsuccessful superhero Awkwardman. After applying Oracle Exaskeleton with extreme scale, he has since rebranded himself as Aquaman. Said Aquaman, “I used to feel so helpless in my skin…now I feel like…well…a highly scaled Engineered System thanks to Oracle!” Thousand of meek and mild individuals eagerly lined up outside Oracle Corporation’s Redwood Shores office to purchase the new Oracle Exaskeleton, with the hope of finally gaining the spine they never had. Unfortunately for the individuals, a bully was spotted allegedly kicking the sand covering the beaches of Redwood Shores into the still spineless Exaskeleton hopefuls. Supporting Quotes “Industry analysts are inquiring if Oracle Exaskeleton is a radical departure from Oracle’s traditional enterprise focus into new markets”, said Oracle representative Sabrina Twich, “Oracle has extensive expertise in unified backbone solutions for application infrastructures…this is simply a new port to the human body combining our Business Intelligence (BI) and RDBC (Remote Direct Brain Cell) technologies.” “With this release of Oracle Exaskeleton, Oracle has redefined scalability. Software and hardware vendors had it all wrong” said the Director of Oracle Exaskeleton, “Scalability for hardware is like…um…you know…so scale-ful. No, wait…can I say that again? I didn’t get that right…Scalability is hardware-on-demand with public and private…hybrid clouds, no…<long pause>…Scalability for… nevermind, I don’t want to be in this stupid press release anyway” Releases An upcoming Oracle Exaskeleton service pack release will include a new datasheet with an extensive library of three-letter acronyms (TLAs) as well as the introduction of more four-letter acronyms (FLAs) since technologies vendors have used up almost all of the 17,576 TLA permutations (TLAPs). About Oracle Oracle engineers hardware and software to work together in the cloud and in your data center. It would be an amazing coincidence if any of this is true in some secret Oracle lab, but I doubt it. Trademarks Really…you’re still reading this? Cool!

In real life, we are willing to pay a price for performance –i.e. to have information at our fingertips. We have run into customers opting to store a document folder path as a document metadata field. They have their reasons, half of the ECM community will agree with them, and the other half would raise an eye brow. In the end, they are getting creative to achieve their document management goals. The below steps outlines how to create a Global Rule that would store a document’s folder path in a custom metadata field: Create a Global Rule via Configuration Manager > Rules Tab > Add Then check “Is global rule with priority”. Then check “Use rule activation condition”. The go to “Edit” and check the actions for this Script Properties: Then click OK, and the following rule activation condition will appear: Then Goto to the Fields Tab and add a Rule Field: Select the target Custom Metadata Field and click Ok, then check the “Is derived field”, then “Edit”, then go to the Custom Tab in the Script Properties window and enter the below custom script: <$if #active.dCollectionPath$> <$dprDerivedValue=#active.dCollectionPath$> <$else$> <$dprDerivedValue=#active.xCollectionIDPath$> <$endif$> For more information on the dCollectionPath property, check Section 8.2 Folder Services from the Oracle® Fusion Middleware Services Reference Guide for Oracle Universal Content Management 11g Release 1 (11.1.1) http://docs.oracle.com/cd/E21043_01/doc.1111/e11011/c08_folders002.htm The above rule will keep the Custom Metadata Field updated with the Folder Path information when a document is checked in via the Content Server (CS) Web Interface or the Desktop Integration Suite (DIS).

  • Integrating Coherence & Java EE 6 Applications using ActiveCache

    - by Ricardo Ferreira
    OK, so you are a developer and are starting a new Java EE 6 application using the most wonderful features of the Java EE platform like Enterprise JavaBeans, JavaServer Faces, CDI, JPA e another cool stuff technologies. And your architecture need to hold piece of data into distributed caches to improve application's performance, scalability and reliability? If this is your current facing scenario, maybe you should look closely in the solutions provided by Oracle WebLogic Server. Oracle had integrated WebLogic Server and its champion data caching technology called Oracle Coherence. This seamless integration between this two products provides a comprehensive environment to develop applications without the complexity of extra Java code to manage cache as a dependency, since Oracle provides an DI ("Dependency Injection") mechanism for Coherence, the same DI mechanism available in standard Java EE applications. This feature is called ActiveCache. In this article, I will show you how to configure ActiveCache in WebLogic and at your Java EE application. Configuring WebLogic to manage Coherence Before you start changing your application to use Coherence, you need to configure your Coherence distributed cache. The good news is, you can manage all this stuff without writing a single line of code of XML or even Java. This configuration can be done entirely in the WebLogic administration console. The first thing to do is the setup of a Coherence cluster. A Coherence cluster is a set of Coherence JVMs configured to form one single view of the cache. This means that you can insert or remove members of the cluster without the client application (the application that generates or consume data from the cache) knows about the changes. This concept allows your solution to scale-out without changing the application server JVMs. You can growth your application only in the data grid layer. To start the configuration, you need to configure an machine that points to the server in which you want to execute the Coherence JVMs. WebLogic Server allows you to do this very easily using the Administration Console. In this example, I will call the machine as "coherence-server". Remember that in order to the machine concept works, you need to ensure that the NodeManager are being executed in the target server that the machine points to. The NodeManager executable can be found in <WLS_HOME>/server/bin/startNodeManager.sh. The next thing to do is to configure a Coherence cluster. In the WebLogic administration console, go to Environment > Coherence Clusters and click in "New". Call this Coherence cluster of "my-coherence-cluster". Click in next. Specify a valid cluster address and port. The Coherence members will communicate with each other through this address and port. Our Coherence cluster are now configured. Now it is time to configure the Coherence members and add them to this cluster. In the WebLogic administration console, go to Environment > Coherence Servers and click in "New". In the field "Name" set to "coh-server-1". In the field "Machine", associate this Coherence server to the machine "coherence-server". In the field "Cluster", associate this Coherence server to the cluster named "my-coherence-cluster". Click in "Finish". Start the Coherence server using the "Control" tab of WebLogic administration console. This will instruct WebLogic to start a new JVM of Coherence in the target machine that should join the pre-defined Coherence cluster. Configuring your Java EE Application to Access Coherence Now lets pass to the funny part of the configuration. The first thing to do is to inform your Java EE application which Coherence cluster to join. Oracle had updated WebLogic server deployment descriptors so you will not have to change your code or the containers deployment descriptors like application.xml, ejb-jar.xml or web.xml. In this example, I will show you how to enable DI ("Dependency Injection") to a Coherence cache from a Servlet 3.0 component. In the WEB-INF/weblogic.xml deployment descriptor, put the following metadata information: <?xml version="1.0" encoding="UTF-8"?> <wls:weblogic-web-app xmlns:wls="http://xmlns.oracle.com/weblogic/weblogic-web-app" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd http://xmlns.oracle.com/weblogic/weblogic-web-app http://xmlns.oracle.com/weblogic/weblogic-web-app/1.4/weblogic-web-app.xsd"> <wls:context-root>myWebApp</wls:context-root> <wls:coherence-cluster-ref> <wls:coherence-cluster-name>my-coherence-cluster</wls:coherence-cluster-name> </wls:coherence-cluster-ref> </wls:weblogic-web-app> As you can see, using the "coherence-cluster-name" tag, we are informing our Java EE application that it should join the "my-coherence-cluster" when it loads in the web container. Without this information, the application will not be able to access the predefined Coherence cluster. It will form its own Coherence cluster without any members. So never forget to put this information. Now put the coherence.jar and active-cache-1.0.jar dependencies at your WEB-INF/lib application classpath. You need to deploy this dependencies so ActiveCache can automatically take care of the Coherence cluster join phase. This dependencies can be found in the following locations: - <WLS_HOME>/common/deployable-libraries/active-cache-1.0.jar - <COHERENCE_HOME>/lib/coherence.jar Finally, you need to write down the access code to the Coherence cache at your Servlet. In the following example, we have a Servlet 3.0 component that access a Coherence cache named "transactions" and prints into the browser output the content (the ammount property) of one specific transaction. package com.oracle.coherence.demo.activecache; import java.io.IOException; import javax.annotation.Resource; import javax.servlet.ServletException; import javax.servlet.annotation.WebServlet; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import com.tangosol.net.NamedCache; @WebServlet("/demo/specificTransaction") public class TransactionServletExample extends HttpServlet { @Resource(mappedName = "transactions") NamedCache transactions; protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { int transId = Integer.parseInt(request.getParameter("transId")); Transaction transaction = (Transaction) transactions.get(transId); response.getWriter().println("<center>" + transaction.getAmmount() + "</center>"); } } Thats it! No more configuration is necessary and you have all set to start producing and getting data to/from Coherence. As you can see in the example code, the Coherence cache are treated as a normal dependency in the Java EE container. The magic happens behind the scenes when the ActiveCache allows your application to join the defined Coherence cluster. The most interesting thing about this approach is, no matter which type of Coherence cache your are using (Distributed, Partitioned, Replicated, WAN-Remote) for the client application, it is just a simple attribute member of com.tangosol.net.NamedCache type. And its all managed by the Java EE container as an dependency. This means that if you inject the same dependency (the Coherence cache named "transactions") in another Java EE component (JSF managed-bean, Stateless EJB) the cache will be the same. Cool isn't it? Thanks to the CDI technology, we can extend the same support for non-Java EE standards components like simple POJOs. This means that you are not forced to only use Servlets, EJBs or JSF in order to inject Coherence caches. You can do the same approach for regular POJOs created for you and managed by lightweight containers like Spring or Seam.
