• ArchBeat Link-o-Rama Top 10 for December 9-15, 2012

  - by Bob Rhubart

  You click, we listen. The following list reflects the Top 10 most popular items posted on the OTN ArchBeat Facefbook page for the week of December 9-15, 2012. DevOps Basics II: What is Listening on Open Ports and Files – WebLogic Essentials | Dr. Frank Munz "Can you easily find out which WebLogic servers are listening to which port numbers and addresses?" asks Dr. Frank Munz. The good doctor has an answer—and a tech tip. Using OBIEE against Transactional Schemas Part 4: Complex Dimensions | Stewart Bryson "Another important entity for reporting in the Customer Tracking application is the Contact entity," says Stewart Bryson. "At first glance, it might seem that we should simply build another dimension called Dim – Contact, and use analyses to combine our Customer and Contact dimensions along with our Activity fact table to analyze Customer and Contact behavior." SOA 11g Technology Adapters – ECID Propagation | Greg Mally "Many SOA Suite 11g deployments include the use of the technology adapters for various activities including integration with FTP, database, and files to name a few," says Oracle Fusion Middleware A-Team member Greg Mally. "Although the integrations with these adapters are easy and feature rich, there can be some challenges from the operations perspective." Greg's post focuses on technical tips for dealing with one of these challenges. Podcast: DevOps and Continuous Integration In Part 1 of a 3-part program, panelists Tim Hall (Senior Director of product management for Oracle Enterprise Repository and Oracle’s Application Integration Architecture), Robert Wunderlich (Principal Product Manager for Oracle’s Application Integration Architecture Foundation Pack) and Peter Belknap (Director of product management for Oracle SOA Integration) discuss why DevOps matters and how it changes development methodologies and organizational structure. Good To Know - Conflicting View Objects and Shared Entity | Andrejus Baranovskis Oracle ACE Director Andrejus Baranovskis shares his thoughts -- and a sample application -- dealing with an "interesting ADF behavior" encountered over the weekend. Cloud Deployment Models | B. R. Clouse Looking out for the cloud newbies... "As the cloud paradigm grows in depth and breadth, more readers are approaching the topic for the first time, or from a new perspective," says B. R. Clouse. "This blog is a basic review of cloud deployment models, to help orient newcomers and neophytes." Service governance morphs into cloud API management | David Linthicum "When building and using clouds, the ability to manage APIs or services is the single most important item you can provide to ensure the success of the project," says David Linthicum. "But most organizations driving a cloud project for the first time have no experience handling a service-based architecture and don't see the need for API management until after deployment. By then, it's too late." Oracle Fusion Middleware Security: Password Policy in OAM 11g R2 | Rob Otto Rob Otto continues the Oracle Fusion Middleware A-Team "Oracle Access Manager Academy" series with a detailed look at OAM's ability to support "a subset of password management processes without the need to use Oracle Identity Manager and LDAP Sync." Understanding the JSF Lifecycle and ADF Optimized Lifecycle | Steven Davelaar Could you call that a surprise ending? Oracle WebCenter & ADF Architecture Team (A-Team) member learned a lot more than he expected while creating a UKOUG presentation entitled "What you need to know about JSF to be succesful with ADF." Expanding on requestaudit - Tracing who is doing what...and for how long | Kyle Hatlestad "One of the most helpful tracing sections in WebCenter Content (and one that is on by default) is the requestaudit tracing," says Oracle Fusion Middleware A-Team architect Kyle Hatlestad. Get up close and technical in his post. Thought for the Day "There is no code so big, twisted, or complex that maintenance can't make it worse." — Gerald Weinberg Source: SoftwareQuotes.com

• 13 Lösungen für eine höhere Sicherheit in einer Oracle Datenbank (Best Practices)

  - by C.Muetzlitz

  Externe Einflüsse wie Gesetze fordern die IT auf, (unsere) Daten zu schützen. Doch wie prüft man die eingestellte Sicherheit einer Oracle Datenbank überhaupt? Ist die geforderte Sicherheit ausreichend umgesetzt und zwar im Idealfall entsprechend dem notwendigen Schutzbedarf? Wann haben Sie eigentlich die Sicherheit Ihrer Oracle Datenbank das letzte Mal überprüft? Und noch besser gefragt, kennen Sie die Bedrohungen und die davon abgeleiteten Risiken? Alles Fragen deren Antworten ein verantwortlicher Anwendungsbesitzer sofort parat haben sollte oder sehen Sie das anders? Wie kann man sich am besten vor Bedrohungen schützen? Die einzige richtige Antwort auf diese Frage ist, durch Informationen und daraus abgeleitetes Wissen. Nun umfassen Informationen und das darin versteckte Wissen wahrscheinlich sehr viele Quellen. D.h. es wird immer schwieriger sich das richtige Wissen anzueignen und dieses Wissen für den Schutz von Daten und Datenbanken anzuwenden.Betrachtet man die Oracle Datenbank, dann empfehle ich zwei wesentliche Bereiche, die man tun muss bzw. wissen sollte. Die Best Practices Lösungen kennen, die man implementieren sollte und teilweise muss, um gute Sicherheit zu garantieren.Ich nenne diesen Bereich „13 Lösungen für eine höhere Sicherheit in einer Oracle Datenbank (Best Practices)“ Wie sieht der wirkliche Sicherheitszustand einer Oracle Datenbank aus.Diesen Bereich nenne ich „Check Oracle DB Security“ In diesem Beitrag möchte ich Sie nun in die Grundlagen einer guten Oracle Datenbank Sicherheit einführen und Sie befähigen, den Sicherheitszustand Ihrer Datenbank selber bestimmen zu können. 13 Lösungen für eine höhere Sicherheit in einer Oracle Datenbank (Best Practices)“  Password-Management aktiveren:Seien Sie sich bewusst, dass schwache Passwords eine hohe Bedrohung bedeuten. Aktivieren Sie ein vernünftiges Password Management Kennen Sie den Funktionsumfang Ihrer aktuellen Datenbank Version, auch die Funktionen, die nicht mehr unterstützt werden.Der "New Feature und Upgrade Guide" sollte eine Pflichtlektüre werden. Implementieren Sie eine passende Mindestsicherheit.Oracle liefert hier viele Vorgaben. Haben Sie das Rollen- und Account Management im GriffHier geht es um eine kontrollierte Privilegien-Vergabe (Least Privileg), eine Zwecktrennung im Account Management und eine andauernde Überprüfung des Rollenmanagements und Zugriffskonzepts Sicheres Datenbank Link Konzept implementierenGerade im Bereich der Datenintegration werden wiederholt DB Links in der Datenbank konfiguriert. Diese Links eröffnen u.U. unkontrollierte Zugriffe auf entfernte Datenbanken. Tracken Sie den Zugriff und setzen Sie ein sicheres DB Link Konzept um. Oracle liefert hier die entsprechenden Vorgaben. Definieren Sie Schutz-Policies für Ihre Anwendungen.Hierunter fällt z.B. ein richtiges Anwendungs-Owner und Anwendungs-User Setup Implementieren Sie den notwendigen Datenschutz für wichtige DatenKennen Sie die Daten, die geschützt werden müssen und schützen Sie diese angemessen. Kontrollieren Sie den Ressourcenverbrauch in Ihrer Datenbank Implementieren Sie eine sinnvolle Zwecktrennung in der DatenbankAuch bei der Datenbank ist es sinnvoll eine Zwecktrennung zu implementieren. Schalten Sie eine sinnvolle und gesetzeskonforme Protokollierung ein.Gesetze erfordern das und Oracle gibt eine Mindestprotokollierung vor. Implementieren Sie Prozesse, die den guten Zustand der Datenbank erhalten Führen Sie regelmäßige Health- Checks durchOracle liefert z.B. mit dem Enterprise Manager eine vollständige Library. Definieren Sie ein funktionierendes Patch-ManagementKennen Sie die Critical Patch Updates und handeln Sie falls notwendig. Check Oracle DB Security oder wer den Sicherheitszustand nicht kennt, wird auch keine Maßnahmen ergreifen Den Sicherheitszustand einer Oracle Datenbank zu überprüfen, ist sehr wichtig. Hierfür kann man verschiedene Anwendungen nutzen, die im Markt erhältlich sind. Eine gute Entscheidung wäre z.B. den Oracle Enterprise Manager (Cloud Control) mit dem Lifecycle Management zu nutzen, der periodisch den Sicherheitszustand für Sie ermittelt. Eine manuelle Überprüfung ist auch möglich, erfordert aber tiefes Wissen. Doch auch trotz der hohen Wissensanforderung ist ein Verstehen, wie man eine Oracle Datenbank manuell auf Sicherheit überprüft, wichtig. Vertrauen Sie nicht mehr auf Vermutungen, sondern nehmen Sie die Sicherheit Ihrer Datenbank ernst und lernen Sie den realen Zustand Ihrer Datenbank kennen. Wissen über reale Zustände und Wissen über geeignete Konzepte schützen. Erst dann können Sie entscheiden, welche Maßnahmen tatsächlich notwendig sind.

• SQL SERVER – Configuring Interactive Cleansing Suggestion Min Score for Suggestions in Data Quality Services (DQS) – Sensitivity of Suggestion

  - by pinaldave

  Earlier I talked about what kind of questions, I do not like when I get asked. Today we will go over the question which I like when I get asked the same. One of the reader practices various steps in my earlier blog post Step by Step Guide to Beginning Data Quality Services in SQL Server 2012 – Introduction to DQS. While reading the blog post he noticed that Data Quality Services is not providing very helpful suggestions. He wrote an email to me about it. Let us go over his email. “Pinal, I noticed in one of your images that DQS is not providing very helpful suggestions. First of all DQS should be able to make intelligent guesses and make the necessary correction by itself. If it cannot do the same, in that case, it should give us intelligent suggestions but in the image included here, I see the suggestions are not there as well. Why is it so? Would you please tell me how to increase the numbers of suggestion? I do understand this may not be preferable solution in many case but all the business cases go on it depends. There are cases when the high sensitivity required and there are cases when higher sensitivities are not required. I would like to seek your help here. –Sriram MD” This is indeed a great question. I see that Sriram understands that every system is different and every application has a different need. I will not have to tell him this most important concept. The question is about how to change the sensitivity of suggestions for correction in DQS. Well, this option is available under the configuration tab in the DQS client. Once you click on Configuration you will see the following screen. Click the Tab of General Settings. You will see the section of Interactive Cleansing. Under this second there is the first option of “Min score for suggestions”. As this is set to 0.7 every suggestion which matches 0.7 probabilities or higher probability are displayed under the suggestion tab. You can see in the following image that there is no suggestion as the min score for suggestions is set to 0.7 and there is no record which qualifies to that much confidence. Now let us change the value of Min Score for suggestion to 0.5. The lower value increased the confidence of DQS to give further suggestion to values which are over 0.5. However, in our case the suggestions which it provides are also accurate. This may not be true for your sample. Every sample is different so you should manually review it before approving them. I guess, this is a simple blog post to demonstrate how to change the confidence value for the suggestions which Data Quality Services provides. Use this feature with care and always tune it according to your datasets and record diversity.

• Workflow versioning

  - by Nitra

  I believe I have a fundamental misunderstanding when it comes to workflow engines which I would appreciate if you could help me sort out. I'm not sure if my misunderstanding is specific to the workflow engine I'm using, or if it's a general misunderstanding. I happen to use Windows Workflow Foundation (WWF). TLDR-version WWF allows you to implement business processes in long-running workflows (think months or even years). When started, the workflows can't be changed. But what business process can't change at any time? And if a business process changes, wouldn't you want your software to reflect this change for already started 'instances' of the business process? What am I missing? Background In WWF you define a workflow by combining a set of activites. There are different types of activities - some of them are for flow control, such as the IfElseActivity and the WhileActivty while others allows you to perform actual tasks, such as the CodeActivity wich allows you to run .NET code and the InvokeWebServiceActivity which allows you to call web services. The activites are combined to a workflow using a visual designer. You pretty much drag-and-drop activities from a toolbox to a designer area and connect the activites to each other. The workflow and activities have input paramters, output parameters and variables. We have a single workflow which sometimes runs in a matter of a few days, but it may run for 5-6 months. WWF takes care of persisting the workflow state (what activity are we currently executing, what are the variable values and so on). So far I think WWF makes sense. Some people will prefer to implement a software representation of a business process using a visual designer over writing all of it in code. So what's the issue then? What I don't really get is the following: WWF is designed to take care of long-running workflows. But at the same time, WWF has no built-in functionality which allows you to modify the running workflows. So if you model a business process using a workflow and run that for 6 months, you better hope that the business process does not change. Because if it do, you'll have to have multiple versions of the workflow executing at the same time. This seems like a fundamental design mistake to me, but at the same time it seems more likely that I've misunderstood something. For us, this has had some real-world effects: We release new versions every month, but some workflows may run for a year. This means that we have several versions of the workflow running in parallell, in other words several versions of the business logics. This is the same as having many differnt versions of your code running in production in the same system at the same time, which becomes a bit hard to understand for users. (depending on on whether they clicked a 'Start' button 9 or 10 months ago, the software will behave differently) Our workflow refers to different types of entities and since WWF now has persisted and serialized these we can't really refactor the entities since then existing workflows can't be resumed (deserialization will fail We've received some suggestions on how to handle this When we create a new version of the workflow, cancel all running workflows and create new ones. But in our workflows there's a lot of manual work involved and if we start from scratch a lot of people has to re-do their work. Track what has been done in the workflow and when you create a new one skip activites which have already been executed. I feel that this alternative may work for simple workflows, but it becomes hairy to automatically figure out what activities to skip if there's major refactoring done to a workflow. When we create a new version of the workflow, upgrade old versions using the new WWF 4.5 functionality for upgrading workflows. But then we would have to skip using the visual designer and write code to inject activities in the right places in the workflow. According to MSDN, this upgrade functionality is only intended for minor bug fixes and not larger changes. What am I missing?

• A story of Murphy&ndash;my technical issues at TechDays Switzerland #chtd

  - by Laurent Bugnion

  I had two sessions at the recent Swiss TechDays. While the first one (Advanced Development for Windows Phone 8) went extremely well (I think), I had a very annoying technical issue in the beginning of my second session. First let me add that I talked to Microsoft about that and I hope they will change a few things in the room assignment for next year. My two sessions were one right after the other, with only 15 minutes break to change room. I don’t mind having two sessions so close from each other, but I would really like them to be in the same room in order to avoid having to move my laptops (plural, that will become important later) and redoing the tech check. That being said, I am guilty of not checking where my talks would be before the day before the conference, and when I did notice, it was too late to change it. After my first session, I quickly moved to the other room and setup my main laptop, a Dell Precision. We tested the video output (VGA) and didn’t notice anything special. The projectors are using a fairly high resolution (kudos to the Basel conference center for not having old school 1024x768 projectors anymore, that makes Blend really hard to demo ;) but since everything went great during the first talk, I was not worried. In fact I even had some time to chat with some early attendees about my Microsoft Surface and the Samsung Slate 7, which I had carried with me in addition to the Precision. I just thought it would be nice to show the hardware that Windows 8 can run on, without thinking any further. When the session started, I immediately noticed that the main screen was not showing anything. I thought I had just forgotten to switch to “duplicate” for the video output, and did that with a quick Win-P. However it didn’t “hold”. After 2 seconds, it reverted back to a black display for my attendees. Then I started to really worry. We tried everything, switching from VGA to HDMI, changing the resolution, setting the projector as primary display, but nothing did the trick. The projector was just refusing to show my screen. Now, to show you how despaired I started to be, I even considered using the “extend” setting (which worked just fine), and to use one of the feedback monitors on the floor but really it was super cumbersome. Eventually, my last resort arrived: I started my Samsung Slate 7, which by chance has Visual Studio 12 and Blend 5 installed, plugged the HDMI projector in the dock (yes, I had the dock with me, which I usually don’t!), connected it to internet (had to enter a long password for that), loaded the source code from my main machine using a USB stick and…. finally started to give my presentation. All in all I think we lost about 10 minutes. Amongst the most horrible minutes of my whole life, truly (yes I am blessed, I didn’t have that many horrible minutes in my life ;) I really want to apologize to my attendees. We joked a bit during the attempts to resolve the issue, the reactions I had after the session were all very nice and sympathetic. Only a handful of people left my session while I was having the issues, and I really don’t blame them (who knew how long the problem would last!!). But still, I probably talked at more than 60 sessions over the years, and this was by far my most painful moment. What did I learn? So what did I learn from this? Well from now on I will always have my slate ready with the latest source code, internet connection and every tool I might need during the presentation. This way, if I detect even a hint that the Precision might not work, I will just switch to the Slate. The experience of presenting on the slate is actually not bad at all, it is just a bit slow for my taste, but it does work. By the way, I will be posting the code and slides for my sessions very soon, I just need to “clean it and zip it”. Stay tuned, and thanks again for your patience in that horrible circumstance.

• Desktop Applications Versus Web Applications

  Up until the advent of the internet programmers really only developed one type of application used by end-users.  This type of application was called a desktop application. As the name implies, these applications ran strictly from a desktop computer, and were limited by the resources available to the computer. Initially, this type of applications did not need resources outside of the scope of the computer in which they installed. The problem with this type of application is that if multiple end-users need to access the same desktop application, then the application must be installed on the end-user’s computer. In this age of software development security was not as big of a concern as it is today with other types of applications. This is primarily due to the fact that an end-user must have access to the computer where the software is installed in order for them to access the application. In addition, developers could also password protect the application just in case an authorized end-user was able to gain access to the computer. With the birth of the internet a second form of application emerged because developers were trying to solve inherent issues with the preexisting desktop application. One of the solutions to overcome some of the short comings of desktop applications is the web application. Web applications are hosted on a centralized server and clients only need to have network access and a web browser in order to access the application. Because a web application can be installed on a remote server it removes the need for individual installations of the same application on each end-user’s computer.  The main benefits to an application being hosted on a server is increased accessibility to the application due to the fact that nothing has to be installed on a desktop computer for an end-user to be able to access the application. In addition, web applications are much easier to maintain because any change to the application is applied on the server and is inherently applied to any end-user trying to use the application. This removes the time needed to install and maintain individual installations of a desktop application. However with the increased accessibility there are additional costs that are incurred compared to a desktop application because of the additional cost and maintenance of a server hosting the application. Typically, after a desktop application is purchased there are no additional reoccurring fees associated with the application.  When developing a web based application there are additional considerations that must be addressed compared to a desktop application. The added benefit of increased accessibility also now adds a new failure point when trying to gain access to an application. An end-user now must have network connectivity in order to access the application. This issue is not a concern for desktop applications because there resources are typically bound to the computer in which they run. Since the availability of an application is increased with the use of the client-server model in a web based application, additional security concerns now come in to play. As stated before a, desktop application is bound to the accessibility of the end-user to the computer that the application is installed. This is not the case with web based applications because they potentially could have access from anywhere with the proper internet/network connection. Additional security steps are required to insure the integrity of the application and its data. Examples of these steps include and are not limited to the following: Restricted/Password Areas This form of security is used when specific information can only be accessed by end-users based on a set of accessibility rules. IP Restrictions This form of security is used when only specific locations need to access an application. This form of security is applied from within the web server or a firewall. Network Restrictions (Firewalls) This form of security is used to contain access to an application within a specific sub set of a network. Data Encryption This form of security is used transform personally identifiable information in to something unreadable so that it can be stored for future use. Encrypted Protocols (HTTPS) This form of security is used to prevent others from reading messages being sent between applications over a network.

• How to undo a changeset using tf.exe rollback

  - by Tarun Arora

  Technorati Tags: Team Foundation Server 2010,Team Foundation Utilities,TFS2010   Oh no! Did you just check in a changeset in to TFS and realized that you need to roll back the changeset because the changes were suppose to go in a different branch? Or did you just accidently merge a wrong changeset in your release branch? There are several ways to undo the damage, Manual: Yes, we all just hate this word but for the record you could manually rollback the changes. Get Specific version on the branch and chose the changeset prior to the one you checked in. After that check out all the files in the changeset and check them in. During the check in you will receive a conflict. At this point choose ‘Keep local changes’ in the conflict resolution window and check in the files. Automated: Yes, we just love it! TFS comes with a very powerful command line utility ‘tf.exe’ that gives you the ability to rollback the effects of one or more changesets to one or more version-controlled items. This command does not remove the changesets from an item's version history. Instead, this command creates in your workspace a set of pending changes that negate the effects of the changesets that you specify. Syntax tf rollback /toversion:VersionSpec ItemSpec [/recursive] [/lock:none|checkin|checkout] [/version:versionspec] [/keepmergehistory] [/login:username,[password]] [/noprompt] tf rollback /changeset:ChangesetFrom~ChangesetTo [ItemSpec] [/recursive] [/lock:none|checkin|checkout] [/version:VersionSpec] [/keepmergehistory] [/noprompt] [/login:username,[password]]   I’ll explain this with an example. Your workspace is at the location C:\myWorkspace You want to rollback changeset # 145621 C:\Workspace\MyBranch>tf.exe rollback /changeset:145621 /recursive How do i rollback/undo a series of changesets? You can also rollback a range of changesets by using the following C:\Workspace\MyBranch>tf.exe rollback /changeset:145601~145621 /recursive This will check out the files in the version control and you should be able to see them in the pending changes. Go on check them in to undo the specific changeset that you just rolled back. Do you completely want to get rid of the changeset from all future merges between the two branches? /KeepMergeHistory: This option has an effect only if one or more of the changesets that you are rolling back include a branch or merge change. Specify this option if you want future merges between the same source and the same target to exclude the changes that you are rolling back. Errors “If you get the message ‘Unable to determine the workspace.’ You may be able to correct this by running ‘tf worksapces /collection:TeamProjectCollectionUrl’” you are in the wrong directory. Make sure that you run the ‘tf rollback’ command from the directory of your workspace.   Status Exit Code Description 0 The operation rolled back all items successfully. 1 The operation rolled back at least one item successfully but could not roll back one or more items. 100 The operation could not roll back any items.   To use the command you must have the Read, Check Out, and Check In permissions set to Allow. So, have you been in a rollback undo situation before?   Share this post :

• VirtualBox Clone Root HD / Ubuntu / Network issue

  - by john.graves(at)oracle.com

  When you clone a root Ubuntu disk in VirtualBox, one thing that gets messed up is the network card definition.  This is because Ubuntu (as it should) uses UDEV IDs for the network device.  When you boot your new disk, the network device ID has changed, so it creates a new eth1 device.  Unfortunately, this conflicts with the VirtualBox network setup.  What to do? Boot the box (no network) Edit the /etc/udev/rules.d/70-persistent-net.rules Delete the eth0 line and modify the eth1 line to be eth0 --------- Example OLD ----------- # This file was automatically generated by the /lib/udev/write_net_rules # program, run by the persistent-net-generator.rules rules file. # # You can modify it, as long as you keep each rule on a single # line, and change only the value of the NAME= key. # PCI device 0x8086:0x100e (e1000) <-------------------- Delete these two lines SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="08:00:27:d8:8d:15", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0" # PCI device 0x8086:0x100e (e1000) ---Modify the next line and change eth1 to be eth0 SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="08:00:27:89:84:98", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1" .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } ---------------------------------------- --------- Example NEW ----------- # This file was automatically generated by the /lib/udev/write_net_rules # program, run by the persistent-net-generator.rules rules file. # # You can modify it, as long as you keep each rule on a single # line, and change only the value of the NAME= key. # PCI device 0x8086:0x100e (e1000) SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="08:00:27:89:84:98", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0" .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } ----------------------------------------

• At the Java DEMOgrounds - Oracle Java ME Embedded Enables the “Internet of Things”

  - by Janice J. Heiss

  I caught up with Oracle’s Robert Barnes, Senior Director, Java Product Management, who was demonstrating a new product from Oracle’s Java Platform, Micro Edition (Java ME) product portfolio, Oracle Java ME Embedded 3.2, a complete client Java runtime optimized for microcontrollers and other resource-constrained devices. Oracle’s Java ME Embedded 3.2 is a Java ME runtime based on CLDC 1.1 (JSR-139) and IMP-NG (JSR-228).“What we are showing here is the Java ME Embedded 3.2 that we announced last week,” explained Barnes. “It’s the start of the 'Internet of Things,’ in which you have very very small devices that are on the edge of the network where the sensors sit. You often have a middle area called a gateway or a concentrator which is fairly middle to higher performance. On the back end you have a very high performance server. What this is showing is Java spanning all the way from the server side right down towards the type of chip that you will get at the sensor side as the network.” Barnes explained that he had two different demos running.The first, called the Solar Panel System Demo, measures the brightness of the light.  “This,” said Barnes, “is a light source demo with a Cortex M3 controlling the motor, on the end of which is a sensor which is measuring the brightness of the lamp. This is recording the data of the brightness of the lamp and as we move the lamp out of the way, we should be able using the server to turn the sensor towards the lamp so the brightness reading will go higher. This sends the message back to the server and we can look at the web server sitting on the PC underneath the desk. We can actually see the data being passed back effectively through a back office type of function within a utility environment.” The second demo, the Smart Grid Response Demo, Barnes explained, “has the same board and processor and is still using Java ME embedded with a different app on top. This is a demand response demo. What we are seeing within the managing environment is that people want to track the pricing signals of the electricity. If it’s particularly expensive at any point in time, they may turn something off. This demo sets the price of the electricity as though this is coming from the back of the server sending pricing signals to my home.” The demo had a lamp and a fan and it was tracking the price of electricity. “If I set the price of the electricity to go over 5 cents, then the device will turn off,” explained Barnes. “I can go into my settings and, in this case, change the price to 50 cents and we can wait a minus and the lamp will go off. When I change the pricing signal so that it is lower, the lamp will come back on. The key point is that the Java software we have running is the same across all the different devices; it’s a way to build applications across multiple devices using the same software. This is important because it fixes peak loading on the network and can stops blackouts.” This demo brought me back to a prior decade when Sun Microsystems first promoted  Jini technology, a version of Java that would put everything on the network and give us the smart home. Your home would be automated to tell you when you were out of milk, when to change your light bulbs, etc. You would have access to the web and the network throughout your home.It’s interesting to see how technology moves over time – from the smart home to the Internet of Things.

• How to Speed Up Any Android Phone By Disabling Animations

  Android phones — and tablets, too — display animations when moving between apps and screens. These animations look very slick, but they waste time — especially on fast phones, which could switch between apps instantly if not for the animations. Disabling these animations will speed up navigating between different apps and interface screens on your phone, saving you time. You can also speed up the animations if you’d rather see them. Access the Developer Options Menu First, we’ll need to access the Developer Options menu. It’s hidden by default so Android users won’t stumble across it unless they’re actually looking for it. To access the Developer Options menu, open the Settings screen, scroll down to the bottom of the list, and tap the About phone or About tablet option. Scroll down to the Build number field and tap it repeatedly. Eventually, you’ll see a message appear saying “You are now a developer!”. The Developer options submenu now appears on the Settings screen. You’ll find it near the bottom of the list, just above the About phone or About tablet option. Disable Interface Animations Open the Developer Options screen and slide the switch at the top of the screen to On. This allows you to change the hidden options on this screen. If you ever want to re-enable the animations and revert your changes, all you have to do is slide the Developer Options switch back to Off. Scroll down to the Drawing section. You’ll find the three options we want here — Window animation scale, Transition animation scale, and Animator duration scale. Tap each option and set it to Animation off to disable the associated animations. If you’d like to speed up the animations without disabling them entirely, select the Animation .5x option instead. If you’re feeling really crazy, you can even select longer animation durations. You can make the animations take as much as ten times longer with the Animation 10x setting. The Animator duration scale option applies to the transition animation that appears when you tap the app drawer button on your home screen.  Your change here won’t take effect immediately — you’ll have to restart Android’s launcher after changing the Animator duration scale setting. To restart Android’s launcher, open the Settings screen, tap Apps, swipe over to the All category, scroll down, and tap the Launcher app. Tap the Force stop button to forcibly close the launcher, then tap your device’s home button to re-launch the launcher. Your app drawer will now open immediately, too. Now whenever you open an app or transition to a new screen, it will pop up as quickly as possible — no waiting for animations and wasting processing power rendering them. How much of a speed improvement you’ll see here depends on your Android device and how fast it is. On our Nexus 4, this change makes many apps appear and become usable instantly if they’re running in the background. If you have a slower device, you may have to wait a moment for apps to be usable. That’s one of the big reasons why Android and other operating systems use animations. Animations help paper over delays that can occur while the operating system loads the app.

• Lead, Follow, or Get out of the way

  - by Daniel Moth

  This is one of the sayings (attributed to Thomas Paine) that totally resonated with me from the first time I heard it, which was only 3 years ago during some training course at work: "Lead, Follow, or Get out of the way" You'll find many books with this title and you'll find it quoted by politicians and other leaders in various countries at various times... the quote is open to interpretation and works on many levels. To set the tone of what this means to me, I'll use a simple micro example: In any given conversation, you are either leading it or following it, at different times/snapshots of the conversation. If you are not willing or able to lead it, and you are not willing or able to follow it, then you should depart. The bad alternative which this guidance encourages you NOT to do is to stick around and obstruct progress by not following, not leading, and simply complaining or trying to derail the discussion in no particular direction. The same pattern applies at your position/role at work. Either follow your management/leadership team, or try to lead them to what you think is a better place, or change jobs. Don't stick around complaining about the direction things are going, while not actively trying to either change things or make peace with it. In the previous paragraph you can replace the word "your management" with "the people reporting to you" and the guidance still holds. Either lead your direct reports to where you think they should go, or follow their lead, or change jobs. Complaining about folks not taking direction while doing nothing is not a maintainable state. To me this quote is not about a permanent state, it is not about some people always leading and some always following: It is about a role/hat that anybody can play/wear at any given moment. One minute I am leading you, the next I am following you, and the next we are both following someone else and so on... When there is disagreement, debate the different directions for as long as it takes for you to be comfortable that you can either follow or lead. If you don't become comfortable with either of those, get out of the way. Something to remember is that it is impossible to learn how to lead well, without learning how to follow well (probably deserves its own blog entry)... Things go wrong when someone thinks that they must always be leading, or when everybody wants to follow and nobody steps up to lead... Things go wrong when more than one person wants to lead and they don't try to reach agreement on a shared direction, stubbornly sticking to their guns pulling the rest of the team in multiple directions... Things go wrong when more than one person wants to lead and after numerous and lengthy discussions, none of them decides to follow or get out of the way... Things go wrong when people don't want to lead, don't want to follow, and insist on sticking around... While there are a few ways things that can go wrong as enumerated in the previous paragraph, the most common one in my experience is the last one I mentioned. You'll recognize these folks as the ones that always complain about everything that is wrong with their company/product but do nothing about it. Every time you hear someone giving feedback on how something is wrong or suboptimal, ask them "So now that you identified the problem, what do you think the solution is and what are you doing to drive us to that solution?" The next time things start going wrong, step up and remind everyone: Lead, Follow, or Get out of the way. For more perspectives, and for input to help you form your own interpretation, search the web for this phrase to see in what contexts it is being used (bing, google). Finally, regardless of your political views, I hope you can appreciate if only as an example this perspective of someone leading by actually getting out of the way. Comments about this post by Daniel Moth welcome at the original blog.

• Reducing Deadlocks - not a DBA issue ?

  - by steveh99999

   As a DBA, I'm involved on an almost daily basis troubleshooting 'SQL Server' performance issues. Often, this troubleshooting soon veers away from a 'its a SQL Server issue' to instead become a wider application/database design/coding issue.One common perception with SQL Server is that deadlocking is an application design issue - and is fixed by recoding...  I see this reinforced by MCP-type questions/scenarios where the answer to prevent deadlocking is simply to change the order in code in which tables are accessed....Whilst this is correct, I do think this has led to a situation where many 'operational' or 'production support' DBAs, when faced with a deadlock, are happy to throw the issue over to developers without analysing the issue further....A couple of 'war stories' on deadlocks which I think are interesting :- Case One , I had an issue recently on a third-party application that I support on SQL 2008.  This particular third-party application has an unusual support agreement where the customer is allowed to change the index design on the third-party provided database.  However, we are not allowed to alter application code or modify table structure..This third-party application is also known to encounter occasional deadlocks – indeed, I have documentation from the vendor that up to 50 deadlocks per day is not unusual !So, as a DBA I have to support an application which in my opinion has too many deadlocks - but, I cannot influence the design of the tables or stored procedures for the application. This should be the classic - blame the third-party developers scenario, and hope this issue gets addressed in a future application release - ie we could wait years for this to be resolved and implemented in our production environment...But, as DBAs  can change the index layout, is there anything I could do still to reduce the deadlocks in the application ?I initially used SQL traceflag 1222 to write deadlock detection output to the SQL Errorlog – using this I was able to identify one table heavily involved in the deadlocks.When I examined the table definition, I was surprised to see it was a heap – ie no clustered index existed on the table.Using SQL profiler to see locking behaviour and plan for the query involved in the deadlock, I was able to confirm a table scan was being performed.By creating an appropriate clustered index - it was possible to produce a more efficient plan and locking behaviour.So, less locks, held for less time = less possibility of deadlocks. I'm still unhappy about the overall number of deadlocks on this system - but that's something to be discussed further with the vendor.Case Two,  a system which hadn't changed for months suddenly started seeing deadlocks on a regular basis. I love the 'nothing's changed' scenario, as it gives me the opportunity to appear wise and say 'nothings changed on this system, except the data'.. This particular deadlock occurred on a table which had been growing rapidly. By using DBCC SHOW_STATISTICS - the DBA team were able to see that the deadlocks seemed to be occurring shortly after auto-update stats had regenerated the table statistics using it's default sampling behaviour.As a quick fix, we were able to schedule a nightly UPDATE STATISTICS WITH FULLSCAN on the table involved in the deadlock - thus, greatly reducing the potential for stats to be updated via auto_update_stats, consequently reducing the potential for a bad plan to be generated based on an unrepresentative sample of the data. This reduced the possibility of a deadlock occurring.  Not a perfect solution by any means, but quick, easy to implement, and needed no application code changes. This fix gave us some 'breathing space'  to properly fix the code during the next scheduled application release.   The moral of this post - don't dismiss deadlocks as issues that can only be fixed by developers...

• Migrating a WebLogic Domain from a 32 to a 64 bit JVM/Architecture

  - by adejuanc

  Currently on 32 bit OS which presents a physical constraint when trying to allocate memory. By limit, a 32 bit OS, will not be able to allocate more than 3 GB on a Linux environment, or 2 GB for Windows environment (not considering Physical Address Extension (PAE) implementation, which can increase the maximum allocatable memory). When this limit is reached, a migration to a 64 bit architecture is recommended. Below are the steps on how to install a 64 WebLogic Server version, along with a 64 Bit JVM and then how to migrate the domain to this new environment. Weblogic Server Version: WebLogic Server Version: 10.3.4.0 OS: Linux adejuan-cl.cl.oracle.com 2.6.18-194.el5 #1 SMP Mon Jan 01 22:10:29 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux JVM:java version "1.6.0_22" Java(TM) SE Runtime Environment (build 1.6.0_22-b04) Oracle JRockit(R) (build R28.1.1-13-139783-1.6.0_22-20101206-0136-linux-x86_64, compiled mode) To create migration template: 1. Execute $<WLS_HOME>/wlserver_10.3/common/bin/config_builder.sh 2. Create Domain Template. 3. Select Domain to migrate. 4. Enter the name of template and other info. Click next. 5. Using Add Button, Select libraries you want to add under lib folder. copy jdbc data sources you would like to have under config/jdbc folder. If you want to have log4j configuration, copy log4j.xml under domain_root folder. 6. Select data base for the domain and click next. 7. Enter Admin Server Name and port numbers. Click next. 8. Enter username and password. Click next. Select No if you don want to add users/groups/roles 9. Click next until reach button create. This will create a jar file that is needed for the next action plan. To install and migrate domain to 64 bit architecture. 1. Install JVM Jrockit R28.1.1.13 on environment. (uncompress zip folder on a known location) 2. Go to JRockit_Home/bin and execute $ java -d64 -jar wls1034_generic.jar 3. When prompt, select JRockit JVM in browse menu, and wait for installation to finish. 4. Go to <WLS_HOME>/wlserver_10.3/common/bin and execute $ ./config.sh 5. Select Create a new Weblogic domain 6. Select Base this domain on an existing template and select browse. 7. Select jar file created on previous action plan. 8. Select Name of domain. Maintain in most cases. 9. Select user name and password. Maintain in most cases. 10. Select Jrockit SDK 1.6.0_22 and click next. 11. Confirm all JMS/JDBC/security configuration. 12. On select Optional Configuration, reconfigure if necessary. 13. Check on Configuration summary for all domain configuration. 14. Click on create, to finish up domain import. Note: Always when installing a 64 bit WLS, it's necessary to install first the 64 JVM and then run the generic installer with the -d64 bit option. If this is not performed, the installation will be the 32 default version. For more information, please refer: http://download.oracle.com/docs/cd/E13188_01/jrockit/docs50/dev_faq.html#pae

• Utility to Script SQL Server Configuration

  - by Bill Graziano

  I wrote a small utility to script some key SQL Server configuration information. I had two goals for this utility: Assist with disaster recovery preparation Identify configuration changes I’ve released the application as open source through CodePlex. You can download it from CodePlex at the Script SQL Server Configuration project page. The application is a .NET 2.0 console application that uses SMO. It writes its output to a directory that you specify.  Disaster Planning ScriptSqlConfig generates scripts for logins, jobs and linked servers.  It writes the properties and configuration from the instance to text files. The scripts are designed so they can be run against a DR server in the case of a disaster. The properties and configuration will need to be manually compared. Each job is scripted to its own file. Each linked server is scripted to its own file. The linked servers don’t include the password if you use a SQL Server account to connect to the linked server. You’ll need to store those somewhere secure. All the logins are scripted to a single file. This file includes windows logins, SQL Server logins and any server role membership.  The SQL Server logins are scripted with the correct SID and hashed passwords. This means that when you create the login it will automatically match up to the users in the database and have the correct password. This is the only script that I programmatically generate rather than using SMO. The SQL Server configuration and properties are scripted to text files. These will need to be manually reviewed in the event of a disaster. Or you could DIFF them with the configuration on the new server. Configuration Changes These scripts and files are all designed to be checked into a version control system.  The scripts themselves don’t include any date specific information. In my environments I run this every night and check in the changes. I call the application once for each server and script each server to its own directory.  The process will delete any existing files before writing new ones. This solved the problem I had where the scripts for deleted jobs and linked servers would continue to show up.  To see any changes I just need to query the version control system to show many any changes to the files. Database Scripting Utilities that script database objects are plentiful.  CodePlex has at least a dozen of them including one I wrote years ago. The code is so easy to write it’s hard not to include that functionality. This functionality wasn’t high on my list because it’s included in a database backup.  Unless you specify the /nodb option, the utility will script out many user database objects. It will script one object per file. It will script tables, stored procedures, user-defined data types, views, triggers, table types and user-defined functions. I know there are more I need to add but haven’t gotten around it yet. If there’s something you need, please log an issue and get it added. Since it scripts one object per file these really aren’t appropriate to recreate an empty database. They are really good for checking into source control every night and then seeing what changed. I know everyone tells me all their database objects are in source control but a little extra insurance never hurts. Conclusion I hope this utility will help a few of you out there. My goal is to have it script all server objects that aren’t contained in user databases. This should help with configuration changes and especially disaster recovery.

• Where should you put constants and why?

  - by Tim Meyer

  In our mostly large applications, we usually have a only few locations for constants: One class for GUI and internal contstants (Tab Page titles, Group Box titles, calculation factors, enumerations) One class for database tables and columns (this part is generated code) plus readable names for them (manually assigned) One class for application messages (logging, message boxes etc) The constants are usually separated into different structs in those classes. In our C++ applications, the constants are only defined in the .h file and the values are assigned in the .cpp file. One of the advantages is that all strings etc are in one central place and everybody knows where to find them when something must be changed. This is especially something project managers seem to like as people come and go and this way everybody can change such trivial things without having to dig into the application's structure. Also, you can easily change the title of similar Group Boxes / Tab Pages etc at once. Another aspect is that you can just print that class and give it to a non-programmer who can check if the captions are intuitive, and if messages to the user are too detailed or too confusing etc. However, I see certain disadvantages: Every single class is tightly coupled to the constants classes Adding/Removing/Renaming/Moving a constant requires recompilation of at least 90% of the application (Note: Changing the value doesn't, at least for C++). In one of our C++ projects with 1500 classes, this means around 7 minutes of compilation time (using precompiled headers; without them it's around 50 minutes) plus around 10 minutes of linking against certain static libraries. Building a speed optimized release through the Visual Studio Compiler takes up to 3 hours. I don't know if the huge amount of class relations is the source but it might as well be. You get driven into temporarily hard-coding strings straight into code because you want to test something very quickly and don't want to wait 15 minutes just for that test (and probably every subsequent one). Everybody knows what happens to the "I will fix that later"-thoughts. Reusing a class in another project isn't always that easy (mainly due to other tight couplings, but the constants handling doesn't make it easier.) Where would you store constants like that? Also what arguments would you bring in order to convince your project manager that there are better concepts which also comply with the advantages listed above? Feel free to give a C++-specific or independent answer. PS: I know this question is kind of subjective but I honestly don't know of any better place than this site for this kind of question. Update on this project I have news on the compile time thing: Following Caleb's and gbjbaanb's posts, I split my constants file into several other files when I had time. I also eventually split my project into several libraries which was now possible much easier. Compiling this in release mode showed that the auto-generated file which contains the database definitions (table, column names and more - more than 8000 symbols) and builds up certain hashes caused the huge compile times in release mode. Deactivating MSVC's optimizer for the library which contains the DB constants now allowed us to reduce the total compile time of your Project (several applications) in release mode from up to 8 hours to less than one hour! We have yet to find out why MSVC has such a hard time optimizing these files, but for now this change relieves a lot of pressure as we no longer have to rely on nightly builds only. That fact - and other benefits, such as less tight coupling, better reuseability etc - also showed that spending time splitting up the "constants" wasn't such a bad idea after all ;-)

• Taking HRMS to the Cloud to Simplify Human Resources Management

  - by HCM-Oracle

  By Anke Mogannam With human capital management (HCM) a top-of-mind issue for executives in every industry, human resources (HR) organizations are poised to have their day in the sun—proving not just their administrative worth but their strategic value as well.  To make good on that promise, however, HR must modernize. Indeed, if HR is to act as an agent of change—providing the swift reallocation of employees  and the rapid absorption of employee data required for enterprises to shift course on a dime—it must first deal with the disruptive change at its own front door. And increasingly, that means choosing the right technology and human resources management system (HRMS) for managing the entire employee lifecycle. Unfortunately, for most organizations, this task has proved easier said than done. This is because while much has been written about advances in HRMS technology, until recently, most of those advances took the form of disparate on-premises solutions designed to serve very specific purposes. Although this may have resulted in key competencies in certain areas, it also meant that processes for core HR functions like payroll and benefits were being carried out in separate systems from those used for talent management, workforce optimization, training, and so on. With no integration—and no single system of record—processes were disconnected, ease of use was impeded, user experience was diminished, and vital data was left untapped.  Today, however, that scenario has begun to change, and end-to-end cloud-based HCM solutions have moved from wished-for innovations to real-life solutions. Why, then, have HR organizations been so slow in adopting them? The answer—it would seem—is, “It’s complicated.” So complicated, in fact, that 45 percent of the respondents to PwC’s “Annual HR Technology Survey” (for 2013) reported having no formal HR software roadmap, and 40 percent stated that they “did not know” whether their organizations would be increasing their use of cloud or software as a service (SaaS) for HR.  Clearly, HR organizations need help sorting through the morass of HR software options confronting them. But just as clearly, there’s an enormous opportunity awaiting those that do. The trick will come in charting a course that allows HR to leverage existing technology while investing in the cloud-based solutions that will deliver the end-to-end processes, easy-to-understand analytics, and superior adaptability required to simplify—and add value to—every aspect of employee management. The Opportunity therefore is to cut costs, drive Innovation, and increase engagement by moving to cloud-based HCM.  Then you will benefit from one Interface, leverage many access points, and  gain at-a-glance insight across your entire workforce. With many legacy on-premises HR systems not being efficient anymore and cloud-based, integrated systems that span the range of HR functions finally reaching maturity, the time is ripe for moving core HR to the cloud. Indeed, for the first time ever there are more HRMS replacement initiatives than HRMS upgrade initiatives under way, and the majority of them involve moving to the cloud per Cedar Crestone’s 2013-2014 HRMS survey. To learn how you can launch your own cloud HCM initiative and begin using HR to power the enterprise, visit Oracle HRMS in the Cloud and Oracle’s new customer 2 cloud program.

• The Three-Legged Milk Stool - Why Oracle Fusion Incentive Compensation makes the difference!

  - by Richard Lefebvre

  During the London Olympics, we were exposed to dozens of athletes who worked with sports psychologists to maximize their performance. Executives often hire business psychologists to coach their teams to excellence. In the same vein, Fusion Incentive Compensation can be used to get people to change their sales behavior so we can make our numbers. But what about using incentive compensation solutions in a non-sales scenario to drive change? Recently, I was working an opportunity where a company was having a low user adoption rate for Salesforce.com, which was causing problems for them. I suggested they use Fusion Incentive Comp to change the reps' behavior. We tossed around the idea of tracking user adoption by creating a variable bonus for reps based on how well they forecasted revenues in the new system. Another thought was to reward the reps for how often they logged into the system or for the percentage of leads that became opportunities and turned into revenue. A new twist on a great product. Fusion CRM's Sweet Spot I'm excited about the sales performance management (SPM) tools in Fusion CRM. This trio of Incentive Compensation, Territory Management, and Quota Management sets us apart from the competition because Oracle is the only vendor that provides all three of these capabilities on a single tech stack, in a single application, and with a single look and feel. The niche vendors offer standalone territory or incentive compensation solutions, but then the customer has to custom build the other tools and can end up with a Frankenstein-type environment. On average, companies overpay sales commissions by three to eight percent. You calculate that number for a company the size of Oracle for one quarter and it makes a pretty air-tight financial case for using SPM tools to figure accurate commissions. Plus when sales reps get the right compensation, they can be out selling rather than spending precious time figuring out what they didn't get paid or looking for another job. And one more thing ... Oracle knows incentive comp. We have been a Gartner Market Scope leader in this space for the last five years. Our solution gets high marks because of its scalability and because of its interoperability with other technologies. And now that we're leading with Fusion, our incentive compensation offering includes the innovations that the Fusion team built, plus enhancements from the E-Business Suite Incentive Comp team. It's a case of making a good thing even better. (See product video.) The "Wedge" Apps In a number of accounts that I'm working on, there is a non-Oracle CRM system of record. That gives me the perfect opportunity to introduce the benefits of our SPM tools and to get the customer using Fusion. Then the door is wide open for the company to uptake more of Fusion CRM, especially since all the integrations they need are out of the box. I really believe that implementing this wedge of SPM tools is the ticket to taking market share away from other vendors. It allows us to insert ourselves in an environment where no other CRM solution in the market has the extending capabilities of Fusion. Not Just Your Usual Suspects Usually the stakeholders that I talk to for Territory Management are tightly aligned with the sales management team. When I sell the quota planning tool, I'm talking to finance people on the ERP side of the house who are measuring quotas and forecasting revenue. And then Incentive Comp is of most interest to the sales operations people, and generally these people roll up to either HR or the payroll department. I think of our Fusion SPM tools as a three-legged stool straddling an organization's Sales, Finance, and HR departments. So when you're prospecting for opportunities -- yes, people with a CRM perspective will be very interested -- but don't limit yourselves to that constituency. You might find stakeholders in accounting, revenue planning, or HR compensation teams. You just might discover, as I did at United Airlines, that the HR organization is spearheading the CRM project because incentive compensation is what they need ... and they're the ones with the budget.

• Rotating WebLogic Server logs to avoid large files using WLST.

  - by adejuanc

  By default, when WebLogic Server instances are started in development mode, the server automatically renames (rotates) its local server log file as SERVER_NAME.log.n.  For the remainder of the server session, log messages accumulate in SERVER_NAME.log until the file grows to a size of 500 kilobytes.Each time the server log file reaches this size, the server renames the log file and creates a new SERVER_NAME.log to store new messages. By default, the rotated log files are numbered in order of creation filenamennnnn, where filename is the name configured for the log file. You can configure a server instance to include a time and date stamp in the file name of rotated log files; for example, server-name-%yyyy%-%mm%-%dd%-%hh%-%mm%.log.By default, when server instances are started in production mode, the server rotates its server log file whenever the file grows to 5000 kilobytes in size. It does not rotate the local server log file when the server is started. For more information about changing the mode in which a server starts, see Change to production mode in the Administration Console Online Help.You can change these default settings for log file rotation. For example, you can change the file size at which the server rotates the log file or you can configure a server to rotate log files based on a time interval. You can also specify the maximum number of rotated files that can accumulate. After the number of log files reaches this number, subsequent file rotations delete the oldest log file and create a new log file with the latest suffix.  Note: WebLogic Server sets a threshold size limit of 500 MB before it forces a hard rotation to prevent excessive log file growth. To Rotate via WLST : #invoke WLSTC:\>java weblogic.WLST#connect WLST to an Administration Serverawls:/offline> connect('username','password')#navigate to the ServerRuntime MBean hierarchywls:/mydomain/serverConfig> serverRuntime()wls:/mydomain/serverRuntime>ls()#navigate to the server LogRuntimeMBeanwls:/mydomain/serverRuntime> cd('LogRuntime/myserver')wls:/mydomain/serverRuntime/LogRuntime/myserver> ls()-r-- Name myserver-r-- Type LogRuntime-r-x forceLogRotation java.lang.Void :#force the immediate rotation of the server log filewls:/mydomain/serverRuntime/LogRuntime/myserver> cmo.forceLogRotation()wls:/mydomain/serverRuntime/LogRuntime/myserver> The server immediately rotates the file and prints the following message: <Mar 2, 2012 3:23:01 PM EST> <Info> <Log Management> <BEA-170017> <The log file C:\diablodomain\servers\myserver\logs\myserver.log will be rotated.

• Why won't my Broadcom BCM4312 LP-PHY work with the STA driver?

I could try again but I remember rebooting and it still said this. What's funny is it found wireless networks during the Ubuntu setup/installation, I don't remember if I got it to connect or not though. I think it kept asking for a password when I put it in (yes it was right I showed password and looked at it) so I just ignored it. But right now the Enable Wireless option in the top right is just gone, it's just Enable Networking and I'm on ethernet on this HP Pavilion dv4-1435dx right here. If I run rfkill list it shows: 0: hp-wifi: Wireless LAN Soft blocked: no Hard blocked: no It was hard blocked at the beginning but unblocking it makes no change. Also it's a touch sensitive button, and it appears to be always orange no matter if it's enabled or not because when I touch it the hard blocked changes between yes and no in rfkill list. I think it was blue for a minute at one point. What is going on?!?! Help me! Lol, thanks for any and all of your time guys. Oh yeah this is Ubuntu 12.10 fresh install.

• Minimum team development sizes

  - by MarkPearl

  Disclaimer - these are observations that I have had, I am not sure if this follows the philosophy of scrum, agile or whatever, but most of these insights were gained while implementing a scrum scenario. Two is a partnership, three starts a team For a while I thought that a team was anything more than one and that scrum could be effective methodology with even two people. I have recently adjusted my thinking to a scrum team being a minimum of three, so what happened to two and what do you call it? For me I consider a group of two people working together a partnership - there is value in having a partnership, but some of the dynamics and value that you get from having a team is lost with a partnership. Avoidance of a one on one confrontation The first dynamic I see missing in a partnership is the team motivation to do better and how this is delivered to individuals that are not performing. Take two highly motivated individuals and put them together and you will typically see them continue to perform. Now take a situation where you have two individuals, one performing and one not and the behaviour is totally different compared to a team of three or more individuals. With two people, if one feels the other is not performing it becomes a one on one confrontation. Most people avoid confrontations and so nothing changes. Compare this to a situation where you have three people in a team, 2 performing and 1 not the dynamic is totally different, it is no longer a personal one on one confrontation but a team concern and people seem more willing to encourage the individual not performing and express their dissatisfaction as a team if they do not improve. Avoiding the effects of Tuckman’s Group Development Theory If you are not familiar with Tuckman’s group development theory give it a read (http://en.wikipedia.org/wiki/Tuckman's_stages_of_group_development) In a nutshell with Tuckman’s theory teams go through these stages of Forming, Storming, Norming & Performing. You want your team to reach and remain in the Performing stage for as long as possible - this is where you get the most value. When you have a partnership of two and you change the individuals in the partnership you basically do a hard reset on the partnership and go back to the beginning of Tuckman’s model each time. This has a major effect on the performance of a team and what they can deliver. What I have seen is that you reduce the effects of Tuckman's theory the more individuals you have in the team (until you hit the maximum team size in which other problems kick in). While you will still experience Tuckman's theory with a team of three, the impact will be greatly reduced compared to two where it is guaranteed every time a change occurs. It's not just in the numbers, it's in the people One final comment - while the actual numbers of a team do play a role, the individuals in the team are even more important - ideally you want to keep individuals working together for an extended period. That doesn't mean that you never change the individuals in a team, or that once someone joins a team they are stuck there - there is value in an individual moving from team to team and getting cross pollination, but the period of time that an individual moves should be in month's or years, not days or weeks. Why? So why is it important to know this? Why is it important to know how a team works and what motivates them? I have been asking myself this question for a while and where I am at right now is this… the aim is to achieve the stage where the sum of the total (team) is greater than the sum of the parts (team members). This is why we form teams and why understanding how they work is a challenge and also extremely stimulating.

• Customer owes me half my payment. Should I take ownership of his AWS account for charging? How?

  - by Cawas

  Background They paid me my first half (back in April 15th) before even we could get into an agreement. Very nice of him! Then I've finished the 2 weeks job of setting up the servers, using his AWS credentials he had just bought. I waited for another 2 weeks for everything settling up, and it was all running fine. He did what he needed with his sftp account, everyone were happy. Now, it has been almost 2 months since I've finished the job and I still didn't get the 2nd half. I must assume, it's not much money (about U$400, converted), but it would help me pay the bills at least. Heck, the Amazon bills they are paying are little less than that (for now). Measures I'm wondering how I can go to charge him now. First thought, of course, would be taking everything down and say "pay now, or be doomed". If that's not good enough, then I lost it. I have no contracts and I doubt I could get a law suit in this country for such a low value based only on emails. And I don't really want to get too agressive here - there might be a business chance in the future and I don't want to ruin it. Second though would be just changing the password. But then he probably could gain access again by some recovery means. That's where my question may mainly relay. How can I do it and not leaving any room for recovery from his side? I even got the first AWS "your account was created" mail from himself, showing me I could begin my job, back then. Lastly, do you have any other idea on what I can and what I should do in this case? Responding to Answers Please, consider reading the current answers and comments. This is not a very simple case. I've considered many, many options (including all lawful ones) before considering this ones I've listed here, and I am willing to take the loss and all that. That's not the point. The point is being practical here. I will call him again and talk about it. I will do terrorism on getting lawyers and getting contract. I am ready to go all forth while I have time and energy for it. But, in practice, there is this extra thing I can do to assure myself of the work I've done. I can basically take it back and delete everything! I'd only take his password because I can find no other way to do it within Amazon. Maybe, contacting Amazon and explaining the situation? I don't know. Give me ideas on this technical side! And thank everyone for the attention and helping me clarifying the issue so far! :)

This variable will be posted on the download page by "Hello, " I tried everthing to complete this, and no luck. Thanks in advance for help.

• Should I manage authentication on my own if the alternative is very low in usability and I am already managing roles?

  - by rumtscho

  As a small in-house dev department, we only have experience with developing applications for our intranet. We use the existing Active Directory for user account management. It contains the accounts of all company employees and many (but not all) of the business partners we have a cooperation with. Now, the top management wants a technology exchange application, and I am the lead dev on the new project. Basically, it is a database containing our know-how, with a web frontend. Our employees, our cooperating business partners, and people who wish to become our cooperating business partners should have access to it and see what technologies we have, so they can trade for them with the department which owns them. The technologies are not patented, but very valuable to competitors, so the department bosses are paranoid about somebody unauthorized gaining access to their technology description. This constraint necessitates a nightmarishly complicated multi-dimensional RBAC-hybrid model. As the Active Directory doesn't even contain all the information needed to infer the roles I use, I will have to manage roles plus per-technology per-user granted access exceptions within my system. The current plan is to use Active Directory for authentication. This will result in a multi-hour registration process for our business partners where the database owner has to manually create logins in our Active Directory and send them credentials. If I manage the logins in my own system, we could improve the usability a lot, for example by letting people have an active (but unprivileged) account as soon as they register. It seems to me that, after I am having a users table in the DB anyway (and managing ugly details like storing historical user IDs so that recycled user IDs within the Active Directory don't unexpectedly get rights to view someone's technologies), the additional complexity from implementing authentication functionality will be minimal. Therefore, I am starting to lean towards doing my own user login management and forgetting the AD altogether. On the other hand, I see some reasons to stay with Active Directory. First, the conventional wisdom I have heard from experienced programmers is to not do your own user management if you can avoid it. Second, we have code I can reuse for connection to the active directory, while I would have to code the authentication if done in-system (and my boss has clearly stated that getting the project delivered on time has much higher priority than delivering a system with high usability). Third, I am not a very experienced developer (this is my first lead position) and have never done user management before, so I am afraid that I am overlooking some important reasons to use the AD, or that I am underestimating the amount of work left to do my own authentication. I would like to know if there are more reasons to go with the AD authentication mechanism. Specifically, if I want to do my own authentication, what would I have to implement besides a secure connection for the login screen (which I would need anyway even if I am only transporting the pw to the AD), lookup of a password hash and a mechanism for password recovery (which will probably include manual identity verification, so no need for complex mTAN-like solutions)? And, if you have experience with such security-critical systems, which one would you use and why?

• Fun tips with Analytics

  - by user12620172

  If you read this blog, I am assuming you are at least familiar with the Analytic functions in the ZFSSA. They are basically amazing, very powerful and deep. However, you may not be aware of some great, hidden functions inside the Analytic screen. Once you open a metric, the toolbar looks like this: Now, I’m not going over every tool, as we have done that before, and you can hover your mouse over them and they will tell you what they do. But…. Check this out. Open a metric (CPU Percent Utilization works fine), and click on the “Hour” button, which is the 2nd clock icon. That’s easy, you are now looking at the last hour of data. Now, hold down your ‘Shift’ key, and click it again. Now you are looking at 2 hours of data. Hold down Shift and click it again, and you are looking at 3 hours of data. Are you catching on yet? You can do this with not only the ‘Hour’ button, but also with the ‘Minute’, ‘Day’, ‘Week’, and the ‘Month’ buttons. Very cool. It also works with the ‘Show Minimum’ and ‘Show Maximum’ buttons, allowing you to go to the next iteration of either of those. One last button you can Shift-click is the handy ‘Drill’ button. This button usually drills down on one specific aspect of your metric. If you Shift-click it, it will display a “Rainbow Highlight” of the current metric. This works best if this metric has many ‘Range Average’ items in the left-hand window. Give it a shot. Also, one will sometimes click on a certain second of data in the graph, like this:  In this case, I clicked 4:57 and 21 seconds, and the 'Range Average' on the left went away, and was replaced by the time stamp. It seems at this point to some people that you are now stuck, and can not get back to an average for the whole chart. However, you can actually click on the actual time stamp of "4:57:21" right above the chart. Even though your mouse does not change into the typical browser finger that most links look like, you can click it, and it will change your range back to the full metric. Another trick you may like is to save a certain view or look of a group of graphs. Most of you know you can save a worksheet, but did you know you could Sync them, Pause them, and then Save it? This will save the paused state, allowing you to view it forever the way you see it now.  Heatmaps. Heatmaps are cool, and look like this:  Some metrics use them and some don't. If you have one, and wish to zoom it vertically, try this. Open a heatmap metric like my example above (I believe every metric that deals with latency will show as a heatmap). Select one or two of the ranges on the left. Click the "Change Outlier Elimination" button. Click it again and check out what it does.  Enjoy. Perhaps my next blog entry will be the best Analytic metrics to keep your eyes on, and how you can use the Alerts feature to watch them for you. Steve

• Wireless connection works but the internet is too slow to use in Ubuntu 11.04

  - by Garrin

  The internet is so slow as to be unusable. And I'm not being picky. Even after minutes I can't get my Google home page to load. I tried installing a package through apt-get and was getting rates between 0 and a few hundred bytes/s. That's bytes, not kilobytes! Mostly 0 however (no exaggeration, it spends large amounts of time stalled). And I would go to a speed test web site of some kind but I can't since nothing will load. Briefly put, the laptop I am using was connected to two wireless networks while using Ubuntu 11.04 without any issues before this. It was also connected to a wired network without any issues. It dual boats Windows 7 which has never had any issues, not even with the current wireless network. Just to be clear, on the current wi-fi network, Windows 7 encounters no issues (speedtest.net puts the network speed at 1mb/s) but my network connection in Ubuntu 11.04 is so slow as to literally be unusable. I am unfamiliar with the router except for the fact that it boasts a Rogers logo (that's a large ISP/cable provider in Canada for those not familiar with the land of igloos and polar bears). I am far from the router and some desktop widget I use tells me the signal strength is at 58% (it seems fairly reliable and this would appear to match up with the filled bars in the network icon). I should also mention I'm just renting a room in this house so I'm not the network administrator and while I can access the 192.168.0.1 router page, the password wasn't set to 'password' so it's not much use to me. Here are a bunch of commands I ran which don't tell me a whole lot but I thought might be more instructive to the wise around here: lspci (just showing my network card): 05:00.0 Network controller: Atheros Communications Inc.
