Updating runtime MSC resource definitions with the UPDATE command

When dynamic resource definition (DRD) is enabled for MSC resources, you can update runtime MSC resources in an online IMS system by using the IMS type-2 UPDATE commands, UPDATE MSLINK, UPDATE MSNAME, and UPDATE MSPLINK.

You cannot update a resource if it is in use.

The resource definitions that you update by using the UPDATE commands are not saved across a cold start unless you export the definitions to the IMSRSC repository or code the changes to the MSC resources into stage-1 system definition macros.

To update runtime MSC resource definitions:

Procedure

  1. Check for work in progress by using a QRY LTERM , QRY MSLINK, QRY MSNAME, or QRY MSPLINK command and either wait for the work to finish or address the work in progress.
  2. Issue the UPDATE command for the type of MSC resource you want to update.
