Maximum Heap Size in Java 5

843829Jan 12 2007 — edited Jan 12 2007
When migrating an application from JDK1.4.2_12 to JDK1.5.0_10,it was seen that the max. heap size that was set using -Xmx had to be reduced from 1.5 GB to 1.3 GB on a win32 machine inorder to create JVM successfully. Any pointers to what in Java 5.0 could have brought about this change is highly appreciated.

(Please note that I understand how heap size allocation works w.r.t virtual memory on win32.)

Restart OAAM instance. Best would be to shut down all OAAM instances, then update the password using EM before starting the OAAM instances again.

I updated the QA_OAAM schema password in this path: weblogic domain/oam_domain/Security/credentials/oaam Map/oaam_db_key and restarted everything.  However, the QA_OAAM db account is still locked.

Where else do I need to update the password?

Thanks

I also unlocked the database account after restarting the oaam managed servers.

My issue has been resolved.

We updated the pwd in the database (to make sure we have the right pwd).

We updated the pwd in weblogic admin console/Service/Data Sources (for all 3 OAAM related data sources).

Shutdown all OAAM admin and managed servers

Logged into the database to unlock the oaam database account

Restarted the oaam admin server (monitor the oaam db account connection using sql developer) in weblogic

Restarted the oaam managed server in weblogic (monitor the oaam db account connection using sql developer).

Once all managed servers are up and running and the oaam db account is not locked, then the issue has been resolved.
