Calling IMS HP Pointer Checker

Use the IMS Database Recovery Facility ADD control statement PC keyword to indicate that you require the single step hash pointer checking function.

HALDB primary indexes and ILDSs are not hash checked by IMS Database Recovery Facility because IMS HP Pointer Checker does not allow for hash pointer checking on HALDB primary indexes and ILDSs. Therefore, IMS HP Pointer Checker is not called for primary indexes and ILDSs after DFSPREC0 rebuilds them.

If you want pointer checking by IMS HP Pointer Checker done, ensure that all logically-related data sets are available to IMS Database Recovery Facility by specifying the PC() keyword on the corresponding ADD commands.

If the logically-related data sets are not available, then IMS HP Pointer Checker returns multiple pointer errors to the IMS Database Recovery Facility primary address space. This can be acceptable if, for example, you only want the Free Space Report from IMS HP Pointer Checker.
