If you want to make dynamic, temporary check updates, use either:

• SDSF- see Using SDSF to manage checks.
• The MODIFY command - See Cheat sheet: examples of MODIFY hzsproc commands.

You can :

• Take one time only actions against checks, such as:
  • Adding and deleting checks
  • Refreshing checks (deleting one or more checks and then adding all eligible checks)
  • Displaying checks and check history
  • Running checks
• Update check values with changes that last until the next refresh (add) of the check or checks, including:
  • Activating and deactivating checks
  • Updating check values. For example, using SDSF and the MODIFY commands, you can update check values, such as interval, severity, category, or check message routing codes.
  Check values changed this way will last just until the check is refreshed (deleted and added again). The system will not apply the changed values to any new checks that you add later. SDSF or MODIFY commands are great for testing check value updates, but to make permanent changes you should create a policy statement to apply the changes to all refreshed and added checks and persist across IBM® Health Checker for z/OS® restarts. See Creating and maintaining IBM Health Checker for z/OS policies.
