Or you can echo the password in as the start of a pipeline.

I think that if you start rman with the password on the command line like below, the password will be visible via the process list (ps or pargs). To avoid this, you should modify the script so that the connection to the database or repository is done in the rman script itself.

I have not had the chance to test it, so I reserve the right to be mistaken.

Well, you must use a decryptable encryption for this to work, but you could always call RMAN like this:

CATALOG_PASSWORD=`decrypt_command encrypted_password_file`

rman target / catalog catalog_user/${CATALOG_PASSWORD}_at_SID script ...

Where the decrypt_command is a command that returns a cleartext password from the 'encrypted_password_file'. It's not the best solution as anyone with execute permissions on decrypt_command and/or read permissions on encrypted_password_file would be able to access the cleartext password. But then again,in several cases security guidelines are not about security, but about compliance.

I have the following commands in a batch file scheduled for daily execution:

set oracle_sid=mydatadb
rman target / catalog mycatusr/mycatpwd_at_mycatdb script Daily_Backup >> backup.log

My organization requires the catalog password (mycatpwd) above to be encrypted and not stored as clear text in any other file or environment variable. How can I still use this batch file for scheduled backups without providing a clear text password?

The only option I can think of is to compile the commands into a binary executable. Any other ideas besides that?

Thanks in advance.
