Creating runtime resource definitions or runtime descriptor definitions dynamically
The CREATE commands can be used to add resources dynamically without having to go through the online change process. You can use the CREATE command with the appropriate parameters to define a new runtime resource definition or runtime descriptor definition.
Runtime resource definitions and runtime descriptor definitions that are created by using the CREATE command exist until the next IMS cold start, unless they are deleted by using the DELETE command.
Runtime resource definitions and runtime descriptor definitions created dynamically by using the CREATE command are recoverable across an IMS warm start or an emergency restart. Resources and runtime descriptor definitions are lost if an IMS system is cold started, unless the resource and descriptor definitions were previously exported to a resource definition data set while IMS was running.
The CREATE command can only be issued through the Operations Manager API. The CREATE command can be used in all IMS environments, although some keywords are restricted. For example, you cannot use the CREATE DB command in an IMS DCCTL environment, and you cannot use the CREATE TRAN command in IMS DBCTL environment.
The CREATE command is not valid in an XRF alternate IMS system or an FDBR region.
The CREATE command is only valid if DRD is enabled. To enable DRD, specify MODBLKS=DYN in either the DFSDFxxx or the DFSCGxxx PROCLIB member.
