System action

The TCP/IP listener task waits for your reply to the WTOR message.

User response

You can reply RESET, SHUTDOWN, or ABEND, with the following results:
RESET
The communication server TCP/IP listener terminates its current connection and then attempts to re-establish a new one.
SHUTDOWN

cbkid TCP/IP listener exceeded forced reset limit. Communication server terminated with abend code U1012.

Explanation

The communication server cbkid listener, since it was last started, has forced an internal reset more times than is allowed. Because this could be a recursive error, the communication server address space terminates with abend code U1012.

System action

CBKxx1520W

cbkid TCP/IP listener task is not APF authorized. Unable to validate client userids.

Explanation

The communication server cbkid has detected, during TCP/IP listener initialization, that the TCP/IP subtask is not APF-authorized. The TCP/IP subtask needs to be APF-authorized to enable it to perform MVS™ host user ID validation.

System action

The TCP/IP listener continues it initialization. However, it is not able to validate the host user ID and password received for each client workstation request it receives.

User response

Your action depends on whether you want user ID validation on the host for workstation client requests as follows:
  • If you don't require host user ID validation, take no action and ignore this message.
  • If you do require host user ID validation, shut down the communication server, ensure all data sets in the STEPLIB library in the communication server startup procedure are APF-authorized, and then restart the server.

Destination

Console

CBKxx1521W

cbkid Validation of client userid skipped due to lack of APF authorization.

Explanation

The communication server cbkid has received a workstation client request, but the TCP/IP listener is unable to validate the host user ID and password associated with the request. This is because the TCP/IP listener subtask is not APF-authorized (see message CBKxx1520W issued during TCP/IP initialization).

System action

The communication server processes the workstation client request without validating the host user ID or password.

User response

Your action depends on whether you want user ID validation on the host for workstation client requests as follows:
  • If you don't require host user ID validation, take no action and ignore this message.
  • If you do require host user ID validation, shut down the communication server, ensure all data sets in the STEPLIB library in the communication server startup procedure are APF-authorized, and then restart the server.

CBKxx1522W

cbkid Client request rejected. Target CICS region applid did not go through CICS BAC shutdown processing.

Explanation

The communication server has received a workstation administration client request. The target CICS region is not available, and that CICS BAC did not go through normal termination the last time it was active in the target CICS region. The CICS BAC region properties defined for the target CICS region specify that client requests are to be rejected in this situation.

System action

The workstation administration client request is rejected.

User response

Depending on the CICS BAC region properties for the target region, you might have to restart CICS BAC in the region to reset the CICS BAC shutdown flag for the region.
