EXAMINE

The EXAMINE command analyzes and reports on the structural integrity of the index and data components of a key-sequenced data set cluster (KSDS) and of a variable-length relative record data set cluster (VRRDS). In addition, EXAMINE can analyze and report on the structural integrity of the basic catalog structure (BCS) of a catalog.

See z/OS DFSMS Using Data Sets for more information on KSDSs and VRRDSs. See How to Run Examine and Understanding Message Hierarchy in z/OS DFSMS Managing Catalogs for more information on BCSs.

See DIAGNOSE for information on the DIAGNOSE command, which inspects the contents of a VVDS or a BCS and looks for logical synchronization errors.

Recommendation: For increased integrity checking, use EXAMINE on the highest available release. Before using EXAMINE with a catalog or data set that has been closed improperly (as a result of a CANCEL, ABEND or system error), use the VERIFY RECOVER command. For more information, see VERIFY.

The syntax of the EXAMINE command is:
