Making IMS and IMSRDR procedures accessible to z/OS

The IMS and IMSRDR procedures initiate the IMS control program region and message regions. Users can copy the sample procedures to IMS.PROCLIB from IMS.SDFSPROC and must add them to SYS1.PROCLIB.

z/OS® with JES2 or JES3: Concatenate IMS.PROCLIB with SYS1.PROCLIB, or move the following procedures to SYS1.PROCLIB:

• IMS
• IMSRDR
• DBC
• DBRC address space procedure
• DL/I address space procedure
• DXRJPROC - IRLM procedure
• DFSMPR
• DFSWTnnn

The IMS PROCLIB data set should be in the master catalog, otherwise, ensure that the volume serial number and unit are on the DD statement. If this is not done, JES2 is unable to initialize.

Any dependent region jobs (IMSMSG, IMSWTnnn) to be specified in the IMS /START REGION command must be added to IMS.JOBS.
