exists; the field itself contains blanks. You can use the update panel to
change an existing password or add a new password.

The maximum queue time is used only if a queue limit is specified in the Queuelimit field, and then
the time limit is applied only when the queue length has reached the queue
limit value.
- NO
- No
limit on the length of time that allocate requests can remain queued.
- nnnn
- The approximate upper limit on the time that allocate requests can be
queued for a connection that appears to be unresponsive. The number represents

network name of the remote system.

- APPC (LUTYPE6.2 protocol)
- Advanced program-to-program communication, or APPC protocol. This is
the default value for ACCESSMETHOD(VTAM).
- EXCI
- The external CICS interface. Specify this to indicate that this connection
is for use by a non-CICS client program using the external CICS interface.

whether, and how, LU6.2 sessions are recovered on system restart within the
persistent session delay interval.

- All sessions are unbound as out-of-service with no CNOS recovery.
- SYSDEFAULT
- If a failed CICS system is restarted within the persistent session delay
interval, the following actions occur:
- User modegroups are recovered to the SESSIONS RECOVOPTION value.
- The SNASVCMG modegroup is recovered.
- The connection is returned in ACQUIRED state and the last negotiated CNOS
state is returned
- N/A
- The PSRecovery value does not apply to this defintion and should not
be validated.
- Queuelimit
- specifies the maximum number of allocate requests that CICS is to queue
while waiting for free sessions:

the partner system.
- FORCE
