5250 Connect User’s Guide

Keep Alive actions will be executed multiple times, at intervals defined by the
Keep Alive parameter defined on the Pool Info dialog of the Logon Connection.
The Inactivity Lifetime parameter (just below Keep Alive on the Pool Info dialog)
tells Composer how long it should wait, in the event the connection is not actually
used by a 5250 Terminal Component, before relinquishing the connection.
NOTE: The execution of the Keep Alive actions of a Logon Component will not
cause the Inactivity Lifetime clock to reset in the Logon Connection. Only a 5250
Terminal component’s execution will reset the Inactivity Lifetime. In other words, if
a live connection is never actually used (but is merely kept alive by “Keep Alive”
actions), then it will time out according to the Inactivity Lifetime value in the Pool
Info dialog. But if the connection is used (by a 5250 component) before it times out,
the timer is reset at that point.
The last action inside a Keep Alive block should be an empty but “enabled”
navigation action. If a user disables this last action, animation will not work
properly due to two consecutive empty navigation actions occurring. For example,
if an action in Logon and the first action in Keep Alive are disabled, an error
occurs.
