Performance issue when Instance running in Cluster

edited Mar 22, 2015 10:00AM in Database - RAC/Scalability (MOSC) 4 commentsAnswered

Hello All,

I  have an environment of Oracle 2 node RAC on Solaris Sparc 5.10 64bit.  There is a performance issue on the nodes when running on Clusters.

I mean if I stop PROD2 instance and run the application using the PROD (PROD1) service , it works fine.

If I stop the PROD1 instance and run the application using the PROD (PROD2 instance) services, it works fine.

The issue is here:

If I start the PROD1 & PROD2 instances and run the jobs/application pointing to either PROD1 , PROD2 or PROD. The performance is very bad.

Example is :

In standalone the application job completes in 2 hrs 30 minutes.

Howdy, Stranger!
