JDK patching happens with every RU since January 2020

Posted on April 22, 2020 by Mike.Dietrich Patch Recommendation 27

Posted on June 29, 2011 by Mike.Dietrich Oracle Database 11g Parameters 0

Recently one of our new upcoming Oracle Database 11.2 reference customers did upgrade their production database – a huge EBS system – from Oracle 9.2.0.8 to Oracle Database 11.2.0.2. They’ve tested very well, we’ve optimized the upgrade process, the recompilation timings etc.

But once the live upgrade was done it did fail in the JAVA component piece with this error:

begin if
initjvmaux.startstep(‘CREATE_JAVA_SYSTEM’) then

ORA-29553:

ORA-06512: at “SYS.INITJVMAUX”, line 23
