Sites using the CA product MIM that performs cross system resource
serialization may receive the following contention message:

MII1038 <jobname1> CONTENTION WITH <jobname2> OWNS EXCL  ON XXXX
MII1039 <jobname1> NEEDS EXCL SYSDSN   SASUSER

If SAS does not find an allocation of the DDNAME SASUSER (as is
typically the case in batch), SAS tries to assign a library, by data
set name, using the value of the SASUSER option as the data set name.
If SASUSER is not defined as a catalog alias on the system, this
results in a dynamic allocation request with the following parms.
Processing this dynamic allocation request may result in a SYSDSN
enqueue request with a DSN of "SASUSER".

            ddname=SASUSER
            dsn=SASUSER
            disp=OLD

Circumvention: Put a //SASUSER DD to a small temporary data set in
the SAS cataloged procedure with a suggested minimum SPACE of 3 tracks.
