Improve performance and maintenance of heavily used SOA composites by Cattle Crew

As stated in a previous post, heavily used transient BPEL processes should be configured with some well-defined parameters in order to avoid storing too much data in the database, thus optimizing performance.

However, even if BPEL processes inside the composite are configured this way, data of other components like mediators and the composite itself are all stored in the database. How much information is stored can be influenced by the audit level setting. As of documentation, the audit levels are defined as follows:

  • Off: No composite instance tracking and payload tracking information is collected. No more composite instances can be created. No logging is performed. Note that disabling logging and the display of instances in Oracle Enterprise Manager Fusion Middleware Control Console can result in a slight performance increase for processing instances. Instances are created, but are not displayed.
  • Development: Enables both composite instance tracking and payload detail tracking. However, this setting may impact performance. This level is useful largely for testing and debugging purposes.
  • Production: Composite instance tracking is collected, but the Oracle Mediator service engine does not collect payload details and the BPEL process service engine does not collect payload details for assign activities (payload details for other BPEL activities are collected). This level is optimal for most normal production operations.

faultsGenerally, the SOA Infrastructure audit level is set to Production or Development - depending on the environment – and the composites are set to inherit this audit level. In case of an intensively used composite this means that a lot of data is persisted in the database.
The audit level, however, can be overridden for every composite. Since the data from the transient, short-lived composites is not needed, the setting Off for the relevant composite should be an interesting option to consider. Three questions must be answered:

  • How much information is persisted from the composite instance?
  • How much information is persisted from the component instances inside the composite?
  • What happens in case of an error?

BPM 11g JDeveloper IDE PS5 Bug for Process ExecData by Andrejus Baranovskis

I was hitting ugly BPM 11g JDeveloper IDE PS5 bug recently. This bug is strange, because is reproduced just after JDeveloper restart for the working process. Imagine you have valid BPM process, everything works well - restart JDeveloper and suddenly BPM process is corrupted. In my specific scenario I was referencing system attribute from BPM execData - execData object is suddenly lost after JDeveloper restart. I don't have solution for this yet, just want to share with you the use case for this BPM 11g JDeveloper IDE PS5 bug.
Sample application (SimpleProcess.zip) contains BPM process with one basic Human Task activity: When you create Human Task activity - execData object is available in Data Associations. Read the full article here.
