I am trying to restore oracle XE by clicking (run as administrator) Restore Database from Start menu -> All Programms ->Oracle Database 10g Express Edition. After entering yes to the confirmation question the error messages appear.
Messages are:
RMAN-00554: Initialization of internal recovery manager package failed
RMAN-04005: error from target database:
ORA-12560: TNS:protocol adapter error
Error: Restore of the database failed.RMAN Error- could not startup dummy instance.

The tnsnames.ora file is in place,the OracleServiceXE and OracleXETNSListener services are running and I am able to connect to xe with sqlplus. What is strange is this problem happened to me a few days ago, after I restarted the machine for a few times it workd and I was able to rstore.This time I couldn't make it work at all.
If it helps,I am running win 7 and I have Oracle 10g client and Oracle 11g client installed on my machine.
Thanks in advance for your reply.

  • Ok, one of my colleagues had this idea to uninstall the oracle express and install it again and that solved my problem! I still don't know the cause, but I am able to restore the db after reinstalling oracle xe. – Silvia Feb 10 '10 at 20:55

    You could put your solution in an "answer" and accept it if you want - future generations will thank you :) – Jeffrey Kemp Feb 11 '10 at 00:41

Is your database server configured for DHCP? If so, you'll need to install the Microsoft Loopback Adapter. Your reinstallation may have just temporarily made the problem go away.
