Scenario RTE06: Deleting a runtime environment

Edit online

Occasionally, you may want to delete an entire runtime environment (RTE). For example, you may want to decomission a test RTE, or an ICAT RTE that you have converted to PARMGEN.

About this task

There are two means of deleting an RTE: from the List of Runtime Environments (RTEs) panel, and from the Access PARMGEN Utilities panel.

From the List of Runtime Environments (RTEs) panel you delete any RTE except the currently selected RTE. From the Access PARMGEN Utilities panel, you can delete only the currently selected RTE.

All the libraries are deleted, except for the persistent data store libraries. These libraries are deliberately not deleted to accommodate another Tivoli Enterprise Monitoring Server in another runtime environment that uses the same sysplex-level persistent datastore libraries.

If you think you might want to recreate the RTE at another time, back up the WK* work libraries. Backing up the work libraries means that you can easily recreate the RTE by running the $PARSE job to recreate the runtime members and jobs and then submitting the appropriate batch jobs to complete the setup of the RTE.

Procedure

To delete an RTE from the Runtime Environments (RTEs) panel, complete the following steps.
1. Enter a question mark (?) in the RTE_NAME field on the Workflow main panel.
  The Runtime Environments (RTEs) panel is displayed.
2. Type D next to the name of the RTE or RTEs that you want to delete, then press Enter.
  A message is displayed warning you that the RTE is about to be deleted without possibility of recovery.
3. Press Enter to delete the RTE.
To delete an RTE from the Access PARMGEN Utilities panel, complete the following steps.
1. Enter UTIL on the command line of any Workflow panel.
  The Access PARMGEN Utilities panel is displayed.
2. Select Delete RTE: %RTE_NAME% (option 25)
  A message is displayed warning you that the RTE is about to be deleted without possibility of recovery.
3. Press Enter to delete the RTE.
