To determine the cause of a Telnet client session hang,
the following is needed:
- Information about what was seen at the client screen
- VTAM® buffer trace of the local device LU
- VTAM internal trace (if the error appears to be in VTAM)
- VTAM TSO trace of the user ID issuing Telnet
- GTF trace of SVC93 and SVC94 (TGET/TPUT)
- Telnet client trace
- Dump of the TSO user’s address space
- TCP/IP packet trace and CTRACE with TELNET option on remote host (if possible)
The preceding list of documentation is a complete list that includes documentation needed to resolve most types of hangs. All of the indicated data might not be needed for each occurrence of a hang. The following analysis section provides information about what types of data might be needed through each diagnostic step.
