IMS Database Repair Facility features and benefits

IMS Database Repair Facility helps you view and change IMS databases. It can be run in interactive or batch mode.

When you run IMS Database Repair Facility in interactive mode, you can accomplish the following tasks:

• Repair database pointers and data.
• Navigate around the database to look for additional problems to verify that no additional repairs are needed.
• Undo recent changes.
• Save time when you repair pointers and data in your IMS databases that use VSAM and OSAM access methods. You can fix only the piece of data in error, rather than forcing you to back out the entire batch of changes that included the bad data.
• Interactively step through your database to look for additional incorrect pointers or data, which provides more reliability.
• Save time and prevent further errors by using the backout capabilities if an incorrect change was made while you use IMS Database Repair Facility.

When you run IMS Database Repair Facility in batch mode, you can accomplish the following tasks:

• Repair both IMS and non-IMS VSAM and OSAM data set pointers and data.
• Verify data before IMS Database Repair Facility modifies it, thus preventing the inadvertent modification of the wrong data.
• Produce a Control Statements and Messages report that documents changes you make.
• Repair VSAM data sets, thus saving you time.

By using the ILK Repair utility together with the HD Pointer Checker utility of IMS HP Pointer Checker, you can repair corrupted HALDB partition reorganization numbers, duplicate ILKs, and potentially duplicate ILKs in HALDB databases. All the databases that are logically related and PSINDEX databases are also repaired.
