IOADUL – Unload IOA Access Method File Contents

The IOADUL utility is used to unload the record contents of an IOA Access Method file data component a sequential file.

Note: When using the IOADUL utility, consider the following:

• This utility can run in parallel with IOA monitors. It is not necessary to shut down monitors for any INCONTROL product when running this utility.
• IOADUL cannot be used for Control-M/Analyzer files.

This utility is typically run to migrate an IOA Access Method file to another DASD volume. In this case, perform the following steps:

1. Run the IOADUL utility to unload the IOA Access Method file data component’s records to a sequential data set.
2. Allocate and format a new IOA Access Method file on a DASD volume using the IOADBF utility.
3. Run the IOADLD utility to reload the IOA Access Method file data component records from the sequential data set previously produced by the IOADUL utility.
4. Run the appropriate index rebuilding utility to rebuild the IOA Access Method file index component, based on the contents of the data component:
   • For IOA databases, use the IOADBIB utility.
   • For Control-D, use the CTDDIB utility.
   • or the Control-V global index file, use the CTDGBIB utility.
   • For the Control-M/Tape media database, use the CTTBIX utility.
   • For the Control-M/Tape stacking database, use the CTTDBIB utility.
