IAS console does not show new 10.1.4.0.1 version after upgrade from 10.1.2.0.2:

This is a problem on all platforms. Oracle says that this is expected behavior. The reason for this being, that OID, SSO and OCA have been upgraded to 10.1.4.0.1 but the core 10g application server components still remain at 10.1.2.0.2. This is reported by bug 6125035. The work around for this is to manually change the version number in the $ORACLE_HOME/config/ias.properties file to 10.1.4.0.1 and bounce iasconsole.
