Merge Process

When you perform a merge operation, following these steps in order:

  1. Terminate all activity against the databases to be merged. Be sure to stop all direct-to-CA View archival activity from the CA Deliver product.
  2. Unload the databases using the UNLOAD function of this utility.
  3. Define a new database (large enough to hold all the data from the input databases) using the ADDDS function of this utility.
  4. Perform the merge function.

    The input unloaded databases are processed twice. The first time, they are scanned to determine how the reset of generation and tape sequence numbers is done; the second time, they are actually loaded to the new, output database.

  5. Verify the successful completion of the merge function.
  6. Run SARINIT to review, add, or change any initialization parameters in the merged database.
  7. Run the SARPAC tape consolidation utility as many times as necessary to copy all the archival tapes to new tapes owned by the merged database.

After you complete Step 6, the newly-created, merged database can be used in production. Step 7 can be run while the database is being used in production.
