Figure 1 shows the expected flows between
a PEM client and CICS PEM server during an unsuccessful sign-on on a PV connection.
Figure 1. Unsuccessful sign-on—PV connection.
This is the expected sequence of events: - The session between the PEM client logical unit and the CICS PEM server
logical unit is established.
- The PEM client gathers data, and sends data for the sign-on program request
to the server, requesting a reply. The request flow contains BB, CD, FMH5,
and data.
- The CICS PEM server ignores the security fields in the FMH5. It processes
the data to issue the sign on (or sign on with changed password). The request
fails.
- The server does not add the user to the signed-on-from list. If the user
is already on the list, the user is purged from it, and a signoff is scheduled.
- The server sends the error reply and deallocates the session. The reply
flow contains CEB and data.
- The client receives and processes the reply.
- The user is not added to the signed-onto list.
Note: CICS schedules sign-off against the PEM client if a sign-on request
for a userid fails, and that user is in the PV signed on from list. In this
case, CICS sends the sign-off transaction program output data to the PEM client,
where it is processed and the userid removed from the PV signed on to list.
