Oracle SOA Suite 11g & WebLogic 11g: automatic start after reboot
1In an previous post I discussed the stop start automated mechanism already, but now I developed a procedure how to automatically startup a complete Oracle SOA Suite 11g after a reboot.
The following components which are involved are:
- Database Instance
- TNS Listener
- Nodemanager
- AdminServer
- SOA Suite Managed server including soa-infra application
The following scripts are used:
- dbora : init service file to stop start the database and listenere during startup
- soa_rc: init service file to start WebLogic and the SOA Suite during startup
UKOUG 2011 – Drag, Drop and other Stuff. Using your Database as a File Server
0Last Thuesday, Mark Drake, Senior Product Manager and I, delivered a good presentation during UKOUG in Birmingham about how to use your database, via XMLDB functionality, as a file server. The presentation demonstrated as well how you could extent the “standaard” file server (aka your database) functionality with features like, WebDAV driven ACL Security and XDB Repository Events, which enable you to automatically trigger event driven actions based on, for example, file naming, content, creator or others.
You can find the presentation on Slideshare or enjoy it here.

Using your Database as a File Server View more presentations from Marco GralikeDuring the demonstration in the second half of the presentation, we demonstrated how you can automatically consume the EXIF and KML information embedded in pictures to use it with the Google Earth API. All the code used for this Google Earth demonstration, and more, can be found on the Oracle XMLDB Sample Code page.
Have fun trying it out and if there any questions, post them on the OTN Oracle XMLDB forum.
WebLogic 12c released!
3At December the 1st, 2011, Oracle announced it’s new major release, the 12c release. As Oracle added the i (internet) at its 8 release, the g(gridcomputing) at its 10 release, now the focus will be on the c(cloudcomputing).
Many new features come out of the fact that Oracle has made its key application server ready for the cloud, that is, ready for to run on enigineered systems, in fact its own Exalogic machine, Oracle’s solution for implementing the cloud.
So let’s take a look what this new release brings us, in this blogpost. There are several new features available in the 12c
New or enhanced WebLogic 12c features- JAVA EE 6 support all kinds of JEE6 specifications are implemented like :
- JSF 2.0,Java Servlets 3.0 JPA 2.0 and EJB 3.1.
- Managed Beans 1.0
- WebLogic 12c also supports supports Java SE 7 (and Java SE 6).
- Java language optimizations and Internationalization
- Client and server support
- SSL/TLS 1.2 in JSSE to support JAVA Socket Transport security
- Converged Java VM:JRockit and HotSpot are  incorporated with the best features from both.The JVM convergence will be a multi-year process, which was confirmed during my presence at Oracle’s Publisher Seminar 2011 during
UKOUG 2011: Using your Database as a Fileserver
0UKOUG 2011 is nearby and one of the coolest things in Oracle 11g and onwards is, IMHO, a functionality called XDB Repository Events. Most of you probably know that based on XMLDB functionality in the database, the database also can be used in a File server kind of way by enabling the XDB Repository HTTP/FTP or WebDav functionality via DBMS_XDB. XDB Repository Events are a kind of “triggers” that enable you to automatically trigger/do something based on the events triggered in this file/folder environment. For example, it is possible to automatically create duplicate files in the XDB Repository or secure them. Other possibilities are to read the content of such a file and insert that content, on the fly during the copy/paste action, into a relational table.
Most APEX enthousiast know of the PL/SQL Gateway, which is a small part of the functionality that is called the XDB Protocol Listener. Besides PL/SQL support, it also enables you to secure your data, as mentioned, trigger actions based, for example on MIME type, mount your database as a Logical Volume (currently only via WebDAV, eg. DAVFS) of your operating system. The XDB Protocol Listener can support your own solutions based More >
Oracle WebLogic 12c has been announced
0Yesterday I received the announcement of the new Oracle WebLogic 12c, on the 1st of December 2012. You can register for a webcast on
So, what’s there to be expected. Personally I think WebLogic has been made Exalogic ready, according to Mike Lehmann, Director of Product Management for Oracle WebLogic.
Some of the few features I expect:
More  Exalogic features like:- Parallel muxers with Java NIO APIs for low-level I/O based operations
- An optimized work scheduler providing improvements to the Increment Advisor used to manage the size of WebLogic Server’s Self-Tuning Thread Pool
- “Lazy” de-serialization of session data on the replica server until required.
- Multiple replication channels for synchronous in-memory session replication between servers in a WebLogic cluster
- Adjustments for supporting the  Infiniband and SDP
Timeouts in Oracle SOA Suite 11g
6Some time ago… at a Oracle SOA 11g project, we had to call an external webservice which took 1 to 5 minutes to respond. The composite calling this webservice was called by another composite from a BPEL process. As you might guess, we got an timeout resulting in faulted instances. Increasing the timeout time wasn’t as easy as I expected, because it’s not one timeout setting that had to be increased, but a total of five timeout settings! To document this for myself in case I run into it again and to help others with the same problem I’ve wrote it down in this blogpost. If you are searching for how to increase the session timeout of the BPM worklist, go to this blogpost. (more…)
