Using In-Memory SOA to Improve System Performance

You can leverage the Coherence cache associated with WebLogic Server to run your non-transactional business processes in memory. This improves performance and scalability for these business processes, as read and write operations are performed out of the cache. Database performance and management also improves, as the costs associated with continuous disk reads and writes are significantly reduced.

Note:

This SOA Suite feature is part of Oracle Integration Continuous Availability. See the Oracle Fusion Middleware Licensing Information for more details on Oracle SOA Suite for Middleware Options.

In-memory SOA enables short-running processes to live in memory. The process state gets written to the database only when faulted, or at regular, deferred intervals using a write-behind thread. The BPEL state information is dehydrated and rehydrated to/from the Coherence cache.

Enable In-Memory SOA

Enable In-Memory SOA through: SOA Administration > common properties > inMemoryEnvironment.

The WLST Script is /net/slc07yxw/scratch/share/wlst/enableInMemory.py (it assumes server is running at default port 7001. userid: weblogic password:weblogic1. Make a copy and update it for your environment).

connect('weblogic', 'weblogic1') custom() cd('oracle.as.soainfra.config/oracle.as.soainfra.config:name=soa-infra,type=SoaInfraConfig,Application=soa-infra') 
set('InMemoryEnvironment', true) 
exit()
