Use the context option in the Status Monitor of the Operations Console to activate or deactivate session message limits on
selected systems or to change the threshold. The setting is changed both in-memory and in the
repository definition.
About this task
The
Session Message Limit option allows you to automatically respond
to the failure of an IMS™ Connect system by balancing the number
of TCP/IP sessions directed to each remaining live IMS Connect
system. The
Limit threshold specifies the maximum number of input messages
for a persistent session. When the threshold is reached, the session is closed by
IMS Connect
Extensions with the expectation that the remote client will create a
new session. Session balance is gradually restored as the existing session expires and new sessions
are routed to the IMS Connect with the lowest session
totals.
The Read Exit Msg Cnt field on the Sessions
tab displays the number of input messages received so far by the session.
Procedure
To implement automatic session re-balancing, perform the following steps:
- Right-click on an IMS Connect system and select from the context menu.
- Under Session Message Limit:
- To activate session message limiting, select Active. In the
Limit threshold field, specify the number of input messages a persistent
session can receive before it will be closed. This value must be between 1 and 999999.
