BPEL Performance tips

Tips for Increasing BPEL Performance: Logging: Set Audit Level to Production Disable sensor and composite audit collection.(This may not be possible when BAM is being used. So, use JMS based BAM data insertion instead) Increase the Invoke Threads ( if there are more invokes than Callbacks), increase Engine Threads ( if there are lots of … Continue reading

How to change the Endpoint for Services in SOA 11g

Use Case: Consider the situation where the MDS contains Concrete WSDLs and all the Services use the MDS Service endpoints for communication (request/response and callbacks).  I had such a situation when the F5 that was used to route the SOA Services in a cluster was not routing the nodes of the cluster properly. HowTo: First, … Continue reading

I. Overview OSB 11g R1 does not have DVM support. Now this is perfectly fine for clients who are using DVMs as part of the SOA Composites. But considering the fact that Oracle Mediator 11g has DVM functionality, and that many clients would have a migration path from Mediator based artifacts to OSB 11g, this … Continue reading

Importing SOA 11g standard XPath Functions into OSB 11g

Ok, so heres the problem. OSB 11g and SOA 11g XPath functions are not in Sync.  So, XSLTs that were developed in SOA 10g cannot be used directly in OSB 11g. One of the strong cases for this is the migration of all ESB based artifacts to OSB artifacts. One of the easiest  ways of … Continue reading

XQuery and XSLT Maps

XSLT used to be everywhere prior to OSB. Now, everyone wants to us XQuery over XSLT for various reasons ranging from the highly controversial better performance and better Code Maintainability. Personally, I feel that XQuery is more procedure driven i.e. you-tell-what-you-want-to-do and hence easier and quicker to script than XSLT which is intuitive and more … Continue reading
