Troubleshooting the TSO Command Interface Utility

Follow the suggested guidelines to diagnose the following common errors associated with invoking the TSO Command Interface Utility:

S047 Abends

If MIMTSO is installed as a command processor, then verify that the MIMTSO module is in a LINKLST library.

If MIMTSO is called from a CLIST, then verify that:

If MIMTSO is installed as a command processor or as a called program, then verify that:

Incomplete Command Responses

The HIBFREXT and BUFRSIZE parameters found in SYS1.PARMLIB(TSOKEYxx) regulate the number of command data you may receive in a TSO session. The total lines you can receive at any one time are equal to the HIBFREXT value divided by the BUFRSIZE value. The total line output can vary due to timing considerations when a user presses the Enter key while messages are being sent to the TSO session. BUFRSIZE=132 and HIBFREXT=6600 gives you a 50-line maximum.

No Output When Using MIMTSO as a Command Processor

Verify that the your TSO PROFILE specifies INTERCOM rather than NOINTERCOM in your TSO user profile. You can check your profile values by issuing the TSO PROFILE command.

'Invalid Command' Message from TSO or ISPF

If MIMTSO is a command processor, then verify that the MIMTSO program is in an APF-authorized loadlib that is being search through LINKLIST processing.

'Insufficient Authority' Messages

For z/OS commands issued through CA MIC, use the CA MIC LINK command to assign authority levels for TSO users. For all CA MIM components, you can change command authority for each TSO user from the default INFO authority by using the MIMCMDXT exit routine.

'CA MIM is not active'

The CA MIM address space needs to be ACTIVE with a valid CMDPREFIX that can be set with the MIMINIT CMDPREFIX statement or the SETOPTION MIM CMDPREFIX command. CMDPREFIX=NONE cannot be specified.

Note: For more information, see the CA MIM Statement and Command Reference Guide.
