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.
