PCIDs

A PCID is an eight-byte field placed in the BIND, UNBIND, and other SNA requests to help an LU distinguish one session from another. It is required when you are running parallel sessions.

A PCID is also known as a session identifier (SID) in VTAM displays. For each session, VTAM prompts you to note the primary or secondary node and displays the Session ID (SID) in hex. This SID is the PCID. If a trace of the BIND is taken, the PCID vector is towards the end.

The following VTAM operator command lists all sessions generated for that LU:
