CTTIDB – Check logical integrity of the Media database

The CTTIDB utility checks the logical integrity of the Media database (MDB) and Stacking database (STK), and checks the relationships between

• index entries and data records
• the high and low level entries in the index file
• records and fields

Note:The CTTIDB utility checks the logical integrity of the database, while the IOADIG utility checks the integrity of the physical structure of the database without referring to its logical data.

When the CTTIDB utility finishes running, it also provides Media Database, Stacking Database, and Trace file statistical information. This includes file size, usage percent, and record type attributes.

Note: If you had previously implemented Dynamic Stacking (by setting DYNSTK to Y in the CTTPARM member), the CTTIDB utility also performs checks on the Stacking Database.
