Return and Error Codes
104706 Tandem Computers Incorporated A–13
27 RC-SESSION-NOT-ALLOCATED
Cause. This indicates that a request was made involving a session that you do not have
allocated. This may be due to the session partner terminating a session that you
opened with the OPEN-SESSION (as opposed to the HLS-OPEN) verb or the session
has been ended by SNAX/HLS because the session partner violated SNA protocol.
Effect. The verb request is rejected.
Recovery. Allocate the session using the HLS-ALLOCATE or OPEN-SESSION verb and
resume activity.
28 RC-CHARMAP-NOT-FOUND
Cause. This indicates that the character map specified in the PROFILE, under which an
attempt has been made to initiate a session, does not exist in the character mapping
file.
Effect. The verb request is rejected.
Recovery. This indicates a configuration error. Use the PEEK command of HLSCOM
to verify that the correct charactermap file is in use by SNAX/HLS. If the correct file is
in use, then the PROFILE record in the RDT file needs to be corrected.
29 RC-RCWT-ALREADY-QUEUED
Cause. This return code indicates that a RECEIVE-CONTROL-WAIT or
RECEIVE-DATA verb request was issued or that send portion of a
SEND-AND-RECEIVE-DATA verb request was complete and SNAX/HLS tried to
honor the receive portion of the request, when a RECEIVE-CONTROL-WAIT verb is
outstanding on the session.
Effect. The verb request is rejected. In the case of the SEND-AND-RECEIVE-DATA
verb, the receive part of the request is rejected.
Recovery. Retry the request once the RECEIVE-CONTROL-WAIT verb request
completes.
This contention may indicate a logic error in your application program.
