Some 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…)
Years ago, when I worked as an Application Support Analyst for a big triple-A Bank, I got acquainted with the BEA product stack.
One of those products was BEA Tuxedo, at that time at the release of 6. I worked at a settlements project, and Tuxedo was used for as distributed transaction processing, to process settlements an clearing messageg from the bank to an international Clearing an Settlements Project, called CLS. It used the SWIFT network to connect; CLSÂ was an international and timezone independent settlements and clearance platform to overcome timezone and bankrupt issues, and prevent a domino effect when an important bank in the chain becomes bankrupt.
Tuxedo is a transaction processing system or transaction-oriented middleware, or enterprise application server for a variety of systems and programming languages.
Tuxedo was designed for high availability and to provideÂ scalable applications to support a lotÂ transactions per second on commonly available distributed systems. It was developed and designed by AT&TÂ if that required online transaction processing (OLTP) capabilities.
Tuxedo is aÂ message routing and queuing system. Requests are sent to named services More >
While working on the challenge to publish a message to a JMS Queue in a remote WebLogic Server from within the Oracle Database – using a Java Stored Procedure – I came across a few things that I would like to record for future reference. Note that unfortunately I have not [yet?] succeeded in making that JMS publication work.
The things I would like to record here are:
- using JDeveloper to developer and load Java Classes and create PL/SQL Wrappers for them
- using the loadjava command line utility to load (the classes in) JAR files into the database
- using the ojvmjava command line utility to try out the classes that have been loaded into the Oracle database directly (which allows us to get access to the console output and the stacktraces when exceptions occur)
If anyone has pointers for my main challenge: publishing a message onto a WebLogic Queue, I would be most interested because even with a lot of help from a lot of (virtual, cyber if not imaginary) friends I have not been able to pull it off. In fact, at this point I am not even able to initialize a JNDI context in a Java Stored Procedure (JSP) through a connection with a remote WLS server.
The Oracle BPM Worklist app is a part of the Oracle SOA Suite. Working with the Worklist app is very annoying, because the default timeout is very short (seconds!). So after getting a cup of coffee or reading a mail you have to login again. Solving this problem seems quite easy by increasing the session timeout in your (generated) ADF human task or in the worklist app in the weblogic console, but it all doesn’t work. The solution for this annoying issue is quite easy, once you know where and how. Here is the trick. (more…)
There are many ways of starting and stopping your Oracle WebLogic 11g Â environments, You can stop your Admin and Managed Server Instances through the Adminsitration console, use the the start and stop scripts shipped with the Oracle WebLogic software and domain creation, or use a tool like WLST to manipulate your entire environment.
In this blog I will Â use the different kinds of techniques to stop and start your Oracle WebLogic Server environment, even in case of a physical host reboot (planned or unplanned)
For this I used the common UNIX shell scripting in combination with WLST
I am presenting later today on the Oracle Fusion Middleware Forum (Spoorwegmuseum, Utrecht). The topic of today’s presentation is cloud computing – especially Platform as a Service – and how WebLogic provides the Platform in the cloud.
