Use EDGUTIL to perform these tasks:
- Create the control data set control record in an empty VSAM data
set described in Creating or updating the control data set control record.
- Update an existing control data set control record described in Creating or updating the control data set control record.
- Verify control data set information to diagnose errors in the
control data set described in Verifying the contents of the control data set.
- Check that control data set information about a volume's status
and the library in which it resides are consistent with the TCDB information,
and optionally the library manager database information described
in Verifying the control data set and tape configuration database. You can optionally generate control statements
to enable mismatches to be synchronized at a later time using the
EDGSPLCS utility. The control statements always include the "Q" verify
request option to enable serialization of the return to scratch processing
performed by EDGSPLCS.
- Synchronize the TCDB information and library manager information
for system-managed volumes with information in the DFSMSrmm control
data set that is described in Synchronizing the contents of the control data set
- Detect consistency errors in control data set information created
during conversion activities and fix the errors that were detected.
Run the mend function against a VSAM copy of the control data set
as the first step in fixing a production control data set. The mend
function should only be used with guidance from IBM Support Center
to determine the underlying cause of any errors in the control data
set. See Mending the control data set for restrictions that you should be
aware of when you use the mend function.
- Enable selected functions:
You can run multiple copies of EDGUTIL (on the same system or on
different systems), and each copy can process a different subset of
volumes. If you use each copy to process a different subset of volumes,
you can potentially reduce the time to complete processing of all
volumes. See SYSIN file for VERIFY and MEND processing for additional information
on running multiple copies of the EDGUTIL utility.
