Database Software

Hello Everyone,

                          I am having problems with cloning an oracle  database (11gr2) using Rman. I have completed all the steps and the process fails during the duplicate process. The clonning is being done from one unix  server to another . These are the steps I have completed so far

1. I created a pfile from the spfile on the target database and moved it to the new server.
2. edited the new(init.ora) file to include the new database name and parameters
3. created all the necessary directories.
4. edited the listener.ora and tnsnames.ora files respectively
5. created the password file on the clone server
6. Took a full backup of the database.

These are the issues I am currently facing.

• I'm unable to connect to the clone database (connect sys /as sysdba) without using a password
• Rman connect auxiliary / does not work without me specifying the sid name.
• below is the sysout when the process fails.

RMAN> run {
2> allocate auxiliary channel c1 device type disk;
3> allocate channel c2 device type disk;
4> duplicate target database to 'IVDBLAB';
5> }

using target database control file instead of recovery catalog
allocated channel: c1
channel c1: SID=298 device type=DISK

allocated channel: c2
channel c2: SID=432 device type=DISK
