CTDDIB – Rebuild Index Component of a User Report List File

The CTDDIB utility is used to rebuild a Control-D User Report List file's index component. The new index component corresponds to information currently contained in the IOA Access Method file's data component. Previous contents of the index component are erased. The main index and alternative index components are rebuilt together or separately.

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

This utility is used when integrity problem is detected in an IOA Access Method file's index component or when an alternative index component is created.

In case of an integrity problem:

• Delete and reallocate the index component.
• Format the index component with the IOADBF utility.
• Rebuild the index component with the CTDDIB utility with parameter ALT=blank/ALL

In case of an alternative index creation:

• Format the index component with the IOADBF utility.
• Activate the alternative index component with the CTDUFANX utility.
• Build the alternative index component with the CTDDIB utility with parameter ALT=ONLY.

Note: This utility marks an alternative index component as ready to use. It causes the alternative index to be used during report search.
