Running DEDB Pointer Checker

You can run the DEDB Pointer Checker utility to perform complete DEDB integrity verification and generate the complete analysis reports. You can also use this function to correct integrity problems that were detected by a DEDB integrity verification process. The reports generated by the DEDB Pointer Checker utility can be used to effectively manage IMS DEDBs.

There are four main steps in running the DEDB Pointer Checker.

1. Allocate and initialize all permanent data sets required by the DEDB Pointer Checker program. If you want to change the return codes of DEDB Pointer Checker, you need to create the return code user exit routines. This is a preprocess to run the DEDB Pointer Checker program, and is done only once.
2. Run the DEDB Pointer Checker program.
3. Correct integrity problems, if there are any.
4. If necessary, analyze the analysis reports and tune your environment.
