If the database was backed up with a third-party product, do the following steps to recover the database:
  1. Restore the database from a valid backup.
    A valid backup requires that
    all
    data sets comprising the database were backed up, and the database was not updated during the backup.
  2. Use SARTDR TADD to add
    View
    backup tapes created since the backup used for Step 1.
  3. Use SARTDR TLOAD to load generations needed for production.
  4. Restart the
    View
    archival task and resume operation.
COPY Disk-to-Disk
Perform the following procedure to recover the database from a media problem:
  1. Run the SARDBASE utility ADDDS function to create a database on alternate DASD.
  2. Run the SARDBASE utility COPY function to copy the data from the old (damaged) database into the new database.
    You can run SARBCH LIST on the old and new databases, to account for any data that were lost in the process.
  3. If necessary, you can restore lost data from backup tapes using SARTDR TADD.
    The output from SARBCH LIST shows the tape sequence number for each SYSOUT. The tape sequence number is part of the last qualifier of the tape data set name, used by SARTDR TADD.
    Notes: 
    If many SYSOUTs are missing, you can save time by using SARDBASE RESTORE as an alternative to SARTDR TADD.
  4. Restart the
    View
    archival task and resume operation.
