Questions about setting up RMAN parallelism for RAC securely

edited May 26, 2015 1:06PM in Database Backup and Recovery (MOSC) 5 commentsAnswered ✓

Hi, DBAs

These are 11.2 RAC databases on Linux x86_64, all using ASM.  RMAN backup scripts run from the servers using crontab.  Right now, I spread the backup jobs across the nodes of the cluster manually.  I would like to take advantage of dynamic channel allocation to distribute the backup load across the online instances, but securely.

Note 1100443.1 specifies that the RMAN connection to the target database needs to be in this form:

rman target username/password@RACDATABASE

(username/password is for a user with SYSDBA privileges).

If one must use a net service name to connect to the target, instead of just "rman /", then the password must be stored in scripts.  Since this is not very secure, is there a way to enable this feature without having to provide a password?

Howdy, Stranger!
