Sense code 08010000 received with CINIT failure

Problem statement

A CINIT request fails with the sense code 08010000 if an application rejects a terminal logon request by issuing the CLSDST macroinstruction.

Common symptoms

The following message is displayed:

IST663I request REQUEST FAILED, SENSE=08010000

The logon from a terminal fails with the USS message USSMSG07.

Probable cause

When an SLU logs on to an application, VTAM® builds a CINIT RU and schedules the LOGON exit routine for the application PLU. If the application is not prepared to accept a session with this SLU, it rejects the logon by issuing a CLSDST macroinstruction. If the application does not supply sense code information about the CLSDST, VTAM builds a negative CINIT response with the sense code 08010000. In many cases, the application will also issue a message indicating the reason for the logon rejection.

User response

Check the message log for a message indicating a failure for this application. Run a buffer trace on the application name to see whether the CINIT passed to the application. The VTAM internal trace with the API option contains data about the LOGON exit and the CLSDST macroinstruction.
