It is possible ... depends on the kind of exception and how you want to process it further ( I mean the design of the flow and corresponding logic ) ..

one of the way would be at places where exceptions are expected , use try catch nodes and one can suitably modify message flow design to handle different situations ..

By using transaction properties provided by some of the nodes one can design their flows to excecute completely only if no exceptions occur or take exceptions as normal and keep processing the trasactions ( Message Flows ) ...

Or wire up Failure or Catch terminals on existing nodes (if applicable)

Looks like there is way in ESQL.

Look for Exit and Continue handlers:
