While
there is a continuous connection between CONTROL-M EM and Control-M/EM Server, the
communication between CONTROL-M/Server and CONTROL-M/Agent is not constant.
CONTROL-M/Server
is doing the following:
1.
It sends a TRACK_ALL message for each agent that has running jobs every
'Polling Interval' (the default is 15 minutes).
2.
There is no indication that an agent becomes unavailable unless there was a
request to that agent.
While
the agent waits for its time window it does not check if the agent is
available. This will be checked only when the job will be submitted.
3. You can check the Agent status using Control-M Configuration Manager.
What
can I do if my agents become unavailable sometimes?
Solution: Run ctm_menu:
(5)
Parameter Customization -> (4) Parameter Customization for Specific Agent
Platform:
Communication
Timeout (default 120)
Maximum
Retries (default 12)
Increase the timeout
parameters for the agent platforms. The same can be achieved using Control-M Configuration Manager. You can open Agent properties and change the parameters accordingly.
