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
EJB an MDB best practices on WebLogic Cluster
2Recently I did an audit on a WebLogic 11g platform of one of our customers. There were many problems with the availability of their JAVA Applications. Some of the problems we’re platform related ( installation, configuration and infrastructure related) but a lot of them already existed in an earlier stage at application programming and configuration level.
So I decided to bundle some tips for JAVA programmers how they should configure their EJB, MDB and Servlet applications when they will be deployed on a WebLogic cluster.
This is an example of a typical EJB application architecture in WebLogic Server:
Some hints and tips:
WLST script to add DataSource and DBAdapter EIS Connection Factory
5Creating a EIS ConnectionFactory in your Database Adapter can be done with the WebLogic Administration Console, but of course this is also “scriptable”. What I needed was a script that created a Data Source with EIS Connection factory bound to the specific datasource.
First I created a properties file, let’s call it DsCf.properties. Everything between <> should be replaced with your own values:

WebLogic 12c: Use JPA in your Web Application
3Where as in WebLogic 11g JPA was not support by default, in WebLogic 12c it is the default persistency provider.JPA 2.0 is part of JAVA EE 6.
I was trying some new JAVA EE 6 features in WebLogic 12c, so here is a is a way to create a Web Application with JPA under WebLogic 12c
Some of the JAVA EE 6 specifications we’re already supported in WebLogic 11g. JPA 2.0 was one of them. Though version 1.0 was the default. 2.0 also worked.Unless an explicit <provider>…</provider> wass specified in the persistence.xml file of a deployed application, WebLogic 11g used OpenJPA/Kodo by default.
The default JPA provider setting is exposed via a new MBean: JPAMBean on the DomainMBean, and persists the configuration into the config.xml file.
Furthermore, you needed to install the patch QWG8 – Enable JPA 2.0 support on WebLogic Server.
To make it work on 11g, you had to use Oracle TopLink as the persistency provider like the image shows you in the WebLogic Admin Console
Now for 12c this is not needed anymore, TopLink will be the default JPA Provider
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
