OCI-64739
Cause
The recovery window golad was not available for the current set of backups. The recovery window goal in the protection policy indicates a desire to be able to restore and recover to any point in time within that range. This is not possible given the current set of backups. Possible reasons are missing archive log backups, missing data file backups or lack of reserved disk space.
Action
Ensure that backups are done regularly. Ensure that your disk reserved space value is set high enough to support your goals. Query RA_DATABASE view for DISK_RESERVED_SPACE and RECOVERY_WINDOW_SPACE parameters and compare these two parameters to ensure enough space has been provisioned to meet your goals. However, you may use the DBMS_RA.UPDATE_PROTECTION_POLICY procedure to increase the DISK_RESERVED_SPACE value to ensure additional backups are saved. Also, check for KEEP backups consuming space on the disk and decide if they should be moved to tape or other disk storage.
