Hi Andy,
there are many different ways to obtain the workload name. The probably
simplest is to issue a Sysevent REQ(F)ASD against the space and find the
workload name in the IRARASD as RASDWKLD.

Hi Kees,
sorry, there is no way to classify based on the existence/specification of a
work qualifier.
On z/OS V2.1 you could simplify your rules by creating a scheduling environment
group but it would still require that the group specification includes all your
scheduling environments.
Horst
Miklos,
it depends on the qualifier what variables are filled in. We intend to add
commentary to provide that information.
In the meantime, SYS1.SAMPLIB(IRAEN55S) has a sample exit that you may find
useful.
