ORA-64738

guaranteed copy suspended for database string

Cause

One of the following operations was performed resulting in the database using more than its allotted disk space:

  • UPDATE_DB lowering the DISK_SPACE_RESERVE value.
  • UPDATE_PROTECTION_POLICY setting the guaranteed_copy parameter to YES
  • DELETE_SBT_LIBRARY where backup data for the given database existed.

New backup requests may be stalled until the system can recompute the safety of allowing additional backup data or backup data may be lost.


Action

This event can be avoided by ensuring backups are written to tape in a timely manner. Conversely, one should avoid the activities listed in the Cause statement when backups are not being written to tape in a timely manner.
