Validate, compare, map, recover, report and regenerate IMS database and program definitions
Ensure IMS database integrity and consistency
IMS™ Library Integrity Utilities for z/OS® helps to validate, compare, map, recover, report and regenerate many IMS libraries needed for operations. It ensures the ACB (Application Control Block), DBD (Database Description), PSB (Program Specification Block) and MFS (Message Format Service) libraries are consistent and have full integrity.
IMS Library Integrity Utilities for z/OS can map and compare database control blocks in these libraries and can re-create source members from compiled control blocks. There is also a sophisticated graphical user interface that shows the relationships between the IMS database and program definitions.
Avoid corruption caused by using an incorrect database description (DBD).
Confirm that all definitions in an IMS subsystem necessary for database operations are in place.
Compare applicable libraries and report on any differences between them.
Regenerate and recover source control statements for library members.
Features
When an IMS database is loaded with one set of database definitions and then later accessed with another set of database definitions, problems can occur that can result in data integrity issues. The IMS™ Library Integrity Utilities for z/OS® tool can detect these problems before they create serious data integrity problems in IMS production databases. The tool can prevent both IMS batch and online applications problems by verifying the IMS control blocks during database authorization.
IMS Library Integrity Utilities ensures IMS DBD (database) and PSB (application) resources are consistent among key libraries.
The tool helps to guarantee that database relationships and definitions exist when the DBD and PSB are created. It has special functions to ensure that the IMS ACB library is consistent and free of problems. It verifies that all ACB members were created at the same IMS version and release level. It can also create an IMS ACB from the IMS DBD and PSB control blocks.
IMS Library Integrity Utilities verifies the consistency of IMS database and application resources across multiple libraries. The tool can check up to ten libraries at once to ensure consistency between IMS DBD, PSB and ACB definitions and between IMS DBRC DB and DSG records in the RECON datasets. The tool can also compare IMS DBD and PSB control blocks that have the same or different names and reside in the same or different libraries.
IMS Library Integrity Utilities can convert IMS DBD, PSB, MFS and ACB control blocks back into their original source control statements. This capability is useful when the original source libraries can no longer be found and the definitions need to change. The tool can compare IMS Message Format Service (MFS) terminal screen definitions that reside in the same or different IMS MFS libraries.
IMS Library Integrity Utilities can create many reports to help IMS database administrators manage the IMS DBD, PSB, ACB and MFS libraries, the IMS DBRC RECON data set and the IMS Catalog. Reports include detailed mappings of the IMS DBD, PSB and ACB definitions—as well as matrix reports showing the comparisons between multiple database and application libraries. There are also reports that summarize the contents of the IMS DBD, PSB and ACB library datasets.
When the IMS Library Integrity Utilities DBD/PSB Viewer extension is installed with IMS Administration Foundation for z/OS, the user can gain a graphical view of the IMS database and application structures. The IMS DBD and PSB source can be seen as well as the relationships between the IMS DBDs and the logical DBDs and the DBDs and the PSBs.
