How to Run EXAMINE

During an EXAMINE run, the following considerations for sharing data sets apply:

No users should be open to the data set while EXAMINE runs.
EXAMINE issues the message "IDC01723I ERRORS MAY BE DUE TO CONCURRENT ACCESS" if it detects any errors; the data set might have been open for output during testing. This message does not necessarily indicate that the reported errors are because of concurrent access.
When you run EXAMINE against a catalog, concurrent access might have occurred without the message being issued. Because system access to the catalog can be difficult to stop, you should not run jobs that would cause an update to the catalog.

For further considerations for data set sharing, see Sharing VSAM Data Sets.

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. See Using VERIFY to Process Improperly Closed Data Sets for more information.
