Cross Check utility

The Cross Check utility provides a z/OS batch utility program to cross check the content of the following IMS components:

• ACB libraries
• DBD libraries
• PSB libraries
• RECON members

When checking an ACB library, the Cross Check utility not only analyzes and reports on the contents of an ACB library, but also compares the DMB and PSB members in an ACB library to corresponding members in a DBD or PSB library. All ACB members are checked for currency versus their counterparts in a DBD or PSB library, which allows you to be aware of DBDs or PSBs that are more current than their corresponding ACB library members.

When checking a DBD library, the Cross Check utility verifies that each DBD with an external reference to another DBD is valid, such as checking that the externally referenced DBD is in the DBD library.

When checking a PSB library, the Cross Check utility verifies that there is a DBD in the DBD library for each DBD referenced by a PSB.

When checking a RECON data set, the Cross Check utility verifies that there is a DBD in the DBD library for each DBD defined in the RECON.
