About this task
You can use Process Manager to
monitor for specific exception conditions when a flow
is run, and specify handlers to run automatically if those exceptions
occur.
You can monitor a flow for the following exceptions:
- Overrun—the flow runs longer than it should
- Underrun—the
flow runs for an abnormally short time
- The flow has
exit code—the flow ends with a particular exit code
- Number
of unsuccessful jobs—a particular number of jobs in the flow are unsuccessful
Procedure
- From the Action menu,
select Add Flow Attribute, or right-click in
a blank section of the flow definition and select Flow
Attribute, and select the Exception Handlers tab.
The Flow Attribute dialog box appears.
- On the
Exception Handling tab, click Add.
- In the Exception type field, select
the exception you want to handle.
- If you chose Runs
more than..., in the Expected run time field,
specify the maximum time, in minutes, the flow can run before it should
be killed.
If you chose Runs less than...,
in the Expected run time field, specify the
minimum time, in minutes, the flow can run before it should be rerun.
If you chose the flow has exit code, in the Value field,
choose the operator and value that best define the exit code requirement.
For example, greater than 5.
If you chose number of unsuccessful jobs, in
the Value field, choose the operator and value
that best define the requirement. For example, greater than 3.
- In the Action field,
select the appropriate exception handler. In most cases, however,
the appropriate exception handler is selected for you, as follows:
If
you monitor for this exception...

handler is used...

- Click OK. The exception
handling specification is added to the list.
- Repeat
steps 2 through 6 until you have finished specifying exceptions to
handle. Click OK.
