The online change function

There are two variations of the online change function: local online change and global online change.

Use the local online function change to make online changes to IMS resources for one IMS.

Use the global online change function to coordinate online changes to IMS resources across all IMS systems in an IMSplex.

Note: When the IMS management of ACBs is enabled, the online change function does not support changing ACBs. Instead, pending ACB changes are activated in online IMS systems by using the IMPORT DEFN SOURCE(CATALOG) command. For more information, see Online changes in managed-ACB environments.
