CTTBIX – Rebuild Media database index

The CTTBIX utility rebuilds the index file for the Media database. The new index file corresponds to information currently contained in the Media database data file.

Note: The index file to be rebuilt must be allocated and formatted prior to activating the utility.

Run the CTTBIX utility only if Control-M/Tape is down or suspended. For further information, see "Table 329CTTBIX EXEC Parameters".

Use this utility

• when the amount of space remaining for the existing index file is insufficient

  In this case

  1. Delete the index file.
  2. Redefine and format the index file with the required amount of space, using the IOADBF utility.
  3. Rebuild the index file.
• for performance improvement
• after recovery
• after converting volumes from other tape management systems (for example, CA-1, CA-TLMS) to Control-M/Tape
