We are upgrading Oracle coherence version from 3.x to 14c (14.1.1-0-1) and are observing higher service mean times for our applications that use coherence cache which lead to low performance.
The coherence cluster configuration we are using is multicast listener and are running performance tests with
- 2 cache servers each running with 3 instances each with storage enabled true
- application processing nodes in the cluster.
For supporting the coherence upgrade, we have also upgraded the
JDK version to 1.8 from 1.6
Ojdbc driver version to ojdbc 8 - 21.6.0.0.1 from ojdbc 14
Any help or directions are greatly appreciated!
Also, any information on how to contact Oracle Coherence Professional Services would be helpful.
