Listed below are the error messages that can occur when SNA Transport intrinsics are being used. They are listed in numerical order according to message number. SNA Transport, itself, does not display these messages: It returns the error number to the SNA service using the intrinsics, and the service can optionally display the message. These messages are not logged; they are written to $STDLIST by the SNA service only.

SNAERR110
MESSAGE

No such deactivation request (UNBIND,DACTLU,DACTPU) received. (SNAERR 110)

CAUSE

An SNA service is trying to send a response to a deactivation request (UNBIND, DACTLU, or DACTPU), but no such deactivation request has been received.

ACTION

The SNA service should examine the situations in which a deactivation response is sent, and verify that a response is sent only after a deactivation request has been received.

SNAERR111
MESSAGE

No such activation request (BIND,ACTLU,ACTPU) received. (SNAERR 111)

CAUSE

An SNA service is trying to send a response to an activation request (BIND, ACTLU, or ACTPU), but no such activation request has been received.

ACTION

The SNA service should examine the situations in which an activation response is sent, and verify that a response is sent only after an activation request has been received.

SNAERR112
MESSAGE

The target parameter passed to iowait is too small. (SNAERR 112)

CAUSE

A target parameter passed in a call to the IOWait intrinsic is too small to receive sense data. The size of the target parameter is checked only when a non-waited call to the SNASendToSSCP intrinsic completes.

SNAERR113
MESSAGE

An error occurred during a switch from CM to NM. (SNAERR 113)

SNAERR115
MESSAGE

Couldn't send BIND on a Secondary LU. (SNAERR 115)

CAUSE

When SNAOpenUser was called to open an LU, the LU was opened as a secondary LU. A secondary LU is not capable of issuing a BIND. However, a call was made to SNASendExpedited, to send a BIND. So, an error occurred.

ACTION

Modify the user program that is calling SNASendExpedited.

SNAERR116
MESSAGE

A waited send intrinsic call was aborted by SNA Transport to avoid a deadlock. (SNAERR 116)

CAUSE

When user data is sent to the remote system, if the pacing window is not open SNA Transport must place the request in its queue. If, at the same time, the remote system sends an expedited request (which is not affected by the pacing window), SNA Transport could hang. To avoid being hung, SNA Transport aborts the previous waited send call and generates this message to warn the user.

ACTION

The user program should handle this situation.
