We want to share with you the solution of one of my costumer, trying to build new environment, and after some step, he has got this RMAN error:
RMAN error:
RMAN-08591: warning: invalid archived log deletion policy
Verification:
After check the RMAN configuration policy, we found:
RMAN> SHOW ARCHIVELOG DELETION POLICY;
RMAN configuration parameters for database with db_unique_name ORCL are:
CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON ALL STANDBY;
RMAN>
Note 1: They are configuring the retention policy of the data guard before the creation of the DG solution.
Note 2: If you are not creating the DG solution, may change the archive log deletion policy to make sure forcing a backup before the delete:
Check this:
RMAN> CONFIGURE ARCHIVELOG DELETION POLICY TO BACKED UP 1 TIMES TO DISK;
Enjoy!
