We were doing OAM 11gR2ps2 to OAM 11gr2Ps3. We also upgraded JDK as part of this upgrade.After that we got errors while starting admin server.

Since we upgraded Java from java version "1.7.0_67" to java version "1.7.0_121".We had to do few additional steps.
As per oracle the cause is "The SSL MD5withRSA support is deprecated as of JDK 1.7 release 95. So the old key/certificate stores when used with later JDK version (ex: 7u101) user started seeing the above reported error."
Solution:
copy old cacerts from old JDK-HOME/jre/lib/security directory to the new JDK-HOME/jre/lib/security directory.
