DFS3631E MSC=Y IS SPECIFIED BUT NO SYSID IS DEFINED.
Explanation
MSC=Y is specified in the IMS execution parameters, but no MSC system identifiers (SYSIDs) are assigned to the IMS system. At least one SYSID must be assigned to the IMS system when MSC=Y is specified in the IMS execution parameters.
System action
IMS initialization terminates with abend 565.
User response
Assign at least one SYSID to the IMS system or specify MSC=N in the IMS execution parameters. When the changes are complete, cold start IMS.
Assign a SYSID to the IMS system by specifying the SYSID parameter in the MSC section of the DFSDFxxx PROCLIB member.
Alternatively, you can assign a SYSID to the IMS system by coding the MSNAME macro as input during the IMS stage-1 system definition process. The stage-1 input must also include an MSPLINK macro and an MSLINK macro.
