Deleting runtime MSC resource definitions with the DELETE command

When dynamic resource definition (DRD) is enabled, you can use the DELETE command to delete runtime MSC resource definitions such as MSC physical links, MSC logical links, MSC MSNAMEs, and MSC remote LTERMs.

The MSC resource definitions that you delete dynamically using the DELETE command remain deleted across a warm or emergency restart.

If you are deleting an MSC resource that is stored in the IMSRSC repository, use the DELETE DEFN command to delete the resource from the repository.

Restriction: You cannot delete a runtime resource definition if it is in use. Examples of resources in use include:
  • An MSC physical link, logical link, or logical link path (MSNAME) that is not stopped
  • An MSC remote LTERM that is not stopped
  • An MSC physical link that is referenced by an MSC logical link
  • An MSC logical link that is referenced by an MSC MSNAME
  • An MSC MSNAME that is referenced by an MSC remote LTERM

To delete 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 DELETE command for the type of MSC resource you want to delete. MSC resources must be deleted in the following order: DELETE LTERM, DELETE MSNAME, DELETE MSLINK, DELETE MSPLINK.

    DELETE MSPLINK is rejected if any logical link references it. DELETE MSLINK is rejected if any logical link path (MSNAME) references it. DELETE MSNAME is rejected if any LTERM references it, or if any remote transaction has its system ID (SYSID) values.
