hi all
Nice KB, which solved our issue. Main two things I have to recreate in Oracle integration....
1. tnsnames.ora resolvation - we have create a tnsnames.ora in network\admin\ path of oracle database.
2. make sure that oracle integration is happening with same user name of Oracle databse which the RMAN is running under.
say in Oracle database the rman is running under xxyy user same we have to create a user in HP DP CM xxyy user name under admin group.
Thanks all....:)
