IRLMNM=name parameter for procedures
Use the IRLMNM=name parameter in procedure to specify the 4-byte z/OS® subsystem name assigned to this IRLM, or the name of the IRLM started by the IMS online or batch system, depending on the procedure type.
IRLM requires a 4-byte name for its internal processing, even though z/OS can accept names with fewer than 4 bytes for subsystem names.
When used with the DXRJPROC procedure, specifies the 4-byte z/OS subsystem name assigned to this IRLM.
When used with the DBBBATCH, DBC, DLIBATCH, IMS, IMSCOBGO, IMSPLIGO, or RDI procedure, specifies the name of the IRLM started by the IMS online or batch system.
