Oracle released the Oracle Enterprise Manager Cloud Administration Guide 12c Release 1 (12.1.0.1) documentation. It is part of the Enterprise Manager Cloud Control Documentation.
Enterprise Manager Cloud Control is system management software that delivers centralized monitoring, administration, and life-cycle management functionality for the complete IT infrastructure, including systems running Oracle and non-Oracle technologies.
While the NoSQL Database Community Edition still waits for final license approval, Oracle has released it’s NoSQL Database, Enterprise Edition 1.1.100. The download is available on OTN.
The Oracle NoSQL Database is a distributed key-value database. It is designed to provide highly reliable, scalable and available data storage across a configurable set of systems that function as storage nodes.
The documentation page is still rather empty. However Technical Overview and a Data Sheet are already available.
Oracle NoSQL is a key offering in Oracle’s portfolio of Big Data products. The product is based on the Java version of Berkeley DB, an open source database used in embedded systems.
Update
Whitehorses published the results of their Oracle Forms Survey on their blog. I’ll share three remarkable results. Please read the whole post on their blog:
- Over 30% is still running Client – Server (Forms 4.5 or 6i).
- Over 50% doesn’t consider upgrading their unsupported version.
- When replacing Oracle Forms APEX is the most considered alternative.
The results are mostly in line with the findings in Germany (on which the survey was based).
Recently I wanted to share a VirtualBox Appliance with a colleague. So I tried to export the created appliance. Unfortunate this failed with a:
VBoxManage.exe: error: Code VBOX_E_FILE_ERROR (0x80BB0004) – File not accessible or erroneous file contents (extended info not available)
So I thought why not just copy it… Oh wait, first compact it to save some space and time using VBoxManage modifyvdi some.vdi compact:
>VBoxManage modifyvdi Windows7.vdi compact
0%...10%...20%...30%...40%...50%...60%...70%...80%...
Progress state: VBOX_E_FILE_ERROR
VBoxManage.exe: error: Code VBOX_E_FILE_ERROR (0x80BB0004) - File not accessible or erroneous file contents (extended info not available)
When I tried to copy or zip the file there were errors accessing it. Somehow the VirtualBox Appliance was still running fine. The files that make up the appliance weren’t locked.
Use CHKDSK
My laptop (the host of the appliance) is is running Windows7 and I decide to run chkdsk and found:
CHKDSK controleert de bestandsgegevens (stap 4 van 5)...
Leesfout met status 0xc0000185 op offset 0x17410c9000 voor 0x10000 bytes.
Leesfout met status 0xc0000185 op offset 0x17410d6000 voor 0x1000 bytes.
Er zijn beschadigde clusters in bestand 37907 met naam \Users\ppvdbeek\VIRTUA~2\Windows7\Windows7.vdi vervangen.
This is Dutch stating that there were bad sectors in the vdi file that had to be corrected. After that I could run the appliance, compact the disk and export the appliance successful.
On Linux you could use fsck (for “file system check”) in a similar case.
When you are using Oracle ESB 10g and encounter the message No WebService Provider is registered at this URL when testing a web service from the ESB Console try the following:
EM OC4J_SOA
Verify the ESB web service providers are generated correctly in ESB runtime (known as the esb-rt):
- Login into Enterprise Manager
- Go to the Application Server Control
- Click OC4J_SOA oc4j instance
- Click Web Services tab
- Verify the deployed web services are listed here, and test that services.
In case there are no web service from the ESB runtime (esb-rt) the service providers were not generated correctly, restart ESB-RT:
- Click OC4J_SOA oc4j instance
- Click the Applications tab
- Expand Middleware Services, ESB and esb-dt
- Check the esb-rt and click the restart button
Now check the j2ee/_instance_name_/log/*/oc4j/log.xml to see if the ESB application has started correctly. Verify that ESB-RT application is initialized correctly by searching for ‘ESB bootstrap: Runtime initialized‘ message in the log file. If you also restarted the ESB-DT, verify that ESB DT application is initialized correctly by searching for ‘ESB bootstrap: Repository initialized‘ message in the log file. And finally check that the ESB web service providers were generated correct (see above).
Some notes and dump of thoughts on the second day of the SOA and E20 Partner Community Forum. A day filled with interesting breakout sessions. Some of them were discussing roadmaps and future developments in the stack, and thus subjective to an NDA.
SOA platform
Again after this session I came to the conclusion that in my opinion BAM is used too little.
During the session was raised whether people in the audience were using non-Oracle databases as dehydration store and Meta Data Store. The mainstream is using Oracle as dehydration store. And although it is certified, it is advised to use Oracle as the database for this purpose. On the Application Server, given the maturity of the J2EE platform, there is less discomfort in operations to deploy the SOA Suite on a non-Oracle App Server.
ADF
Only today I found out that there is an interesting JDeveloper 11g extension. The extension validates ADF code quality. Seems an interesting extension to check code quality besides the already available Java tools.
BPM
When comparing BPEL and BPM and looking into when to use what tool, the following was stated: For all things with human interaction BPM is the tool of choice. In integration driven appraoches BPEL is the tool of choice.
In Oracle point of view BPM includes:
without the need for separate platforms.
Example of a custom Spring Java worklist application for Oracle BPM.

Today I attended the first day of the SOA and E2.0 Partner Community Forum. For a detailed agenda of the event check this link. The event with 200 registrations was hosted at Capgemini in Utrecht, The Netherlands.
Tattie picking
The first keynote by Andrew Sutherland had a few great stories that leaded the way to show the rationale behind the Exalogic platform. This included a personal story on “tattie picking”. The larger part was on productisation and gave examples on increasing effiency in IT. One of the ways for the Exalogic platform is the one that is also used by Apple: If you limit the amount of hardware your OS of software stack has to be compliant with, that introduces a better controlled and optimized environment; “If you know the machine you need less code”. This is resulting in several efficiencies. Efficiencies both in the One Time Costs (CTB) and Recurring Costs (RTB).
One of the sound bites that stayed with me was:
The most sticky stack is the least sticky one
Indicating that the stack that is the most open and complying with standards is the one that is most likely to survive…
SOA/ BPM Reference Case
In the Partner SOA/ BPM Reference Case Leon Smiers of Capgemini introduced us to the BPM practise of Capgemini and two of their BPM cases. One of the quotes that I think is very true was:
SOA supports the success of BPM.
Besides that Leon stressed the structure, insight and compliance advantages that BPM efforts deliver. One of the things they learned by doing was the importance of showing BAM to business people. This really enables you to get visibility on a lot of stuff that is under the hood. Besides that it is a catalyst for generating more business value with ideas from the people you are showing BAM to.
WebCenter/ UCM Reference Case
During the WebCenter/ UCM Reference Case Vikram Setia of Infomentum shared great insight on how to deliver an excellent web site using Oracle technology. He did this in a very lively session showing us around a live site and telling what Oracle technologies were used behind the scenes. Besides the UCM and WebCenter stuff there were some cool uses database thingies like:
- Text Clustering
- Thesaurus
- Locator
SOA and BPM 11gR1 PS3 Update
Another intresting session was the SOA and BPM 11gR1 PS3 Update by David Shaffer. Mr Shaffer showed us some of the history and some of the highlight in the current stack. A more detailed dive into the latter will be on day 2 of the conference.
Wednesday’s Breakout Sessions
On the second day I will be attending the following breakout sessions:
- SOA Suite 11g PS3 & OSB
- ADF/WebCenter 11g integration with BPM Suite 11g
- BPM 11g, Whats New
The 2011 edition of Oracle Open World will be from October 2th to 6th. One of the great ways to experience this events is share your knowledge and submit a paper. This window of opportunity closes at midnight on March 27. Find more info on:
While I had to document these steps for a customer that is new to WebLogic Server, I thought why not share these relatively easy steps in a blog post as well. So here they are. The screen shots that come with it are at the bottom.
Create Data Source
- Use a browser to go to the WLS Console, for example
http://somehost:7001/console/login/LoginForm.jsp
- On the home page, click the Data Sources link. You can find it in the Domain Configurations, Services section;
- On the Summary of JDBC Data Sources page click the New button (to change current configuration click the link of the Data Sources you want to change);
- Choose the Name, JNDI Name, and select the Database Type (Oracle). Click Next to confirm and continue;
- Choose the Database Driver. This is depending on the selected Database Type. We used Thin XA for Instance connections for the Data Sources created in the project. Click Next;
- Click Next after you read the Transaction Options;
- Enter the Connection Properties and after that Next to confirm and continue:
- Database Name
- Host Name
- Port
- Database User Name
- Password
- Click the Test Connection button, and if the test succeeded click next;
- On the Select Targets page check for example the AdminServer. Click finish.
More on configuring JDBC on WebLogic Server can be found here (and the PDF on JDBC admin).
