DFS3601 EXTERNAL SUBSYSTEM(S) NOT DEFINED. COMMAND REJECTED.
Explanation
The external subsystem was not defined, and the
command was rejected. One of the following errors occurred:
- The external subsystem name specified on the IMS command has not been defined to IMS.
- The SUBSYS keyword was used on a /START, /STOP, /DISPLAY, or /CHANGE command, but IMS was not made aware of the presence of external subsystems using the SSM parameter.
- SSM was specified, but the SSM PROCLIB member contained no valid subsystem definitions.
System action
The command is rejected.
Operator response
Ensure that the subsystem name specified is correct, and reenter the command. If the problem persists, notify the system programmer about the receipt of this message.
Programmer response
Corresponding to the error conditions in
the Explanation, take one of the following actions:
- The subsystem name was defined incorrectly or misspelled in the IMS SSM PROCLIB member. Correct the subsystem name, and update the SSM PROCLIB member.
- Specify the IMS parameter SSM with a valid member name.
- In this case, an IMS abend 3041 occurred previously. This problem is an indication that the subsystem PROCLIB member specified using the SSM execute parameter contains no invalid external subsystem definitions. When there are no subsystems to support, the task (TCB) that supports the subsystem structure is then terminated with abend 3041. Correct the PROCLIB member definitions. If IMS is running when the member is corrected, enter the /START SUBSYS command to cause IMS to read the new definitions and establish subsystem connections.
