We are doing pre-production testing aganist a weblogic version 9.2 cluster with several nodes on each of 3 machines. Whenever a new ear is deployed with no cluster restart, the application performance degrades quickly and drastically over time. But if the cluster is restarted before a new ear is started or made active...the application performance is better.
But in the case of a non-clustered enviornment, we observed that the application server does not need a restart after every a new ear deployment.
So the questions are:
- Does the weblogic cluster need to be restarted for every new deployment?
- Is there any other setting that is missing in the cluster setup??
Your valuable input and time is highly appreciated.
Thanks in advance.
