CTTIDB Execution Modes

The CTTIDB utility operates in the following major execution modes:

• CHECK

  In CHECK mode the CTTIDB utility

  • checks the logical integrity of the databases
  • issues error messages if inconsistencies are detected
• REPAIR

  In REPAIR mode the CTTIDB utility

  • checks the logical integrity of the databases
  • issues error messages if inconsistencies are detected
  • generates CTTMUP input control statements to correct the found errors
  • writes CTTMUP control statements to the &OLPREFT.MTU file.

Note: Not all errors reported by CTTIDB can be repaired in REPAIR mode.
In addition, even for those errors that can be repaired, you may need to run CTTIDB in REPAIR mode and then run CTTMUP several times, until CTTIDB no longer reports any errors. This is because the REPAIR mode does not create CTTMUP control statements that are able to repair all reported errors in the Media Database in a single execution.
