In SAS 9, to control the priority that spawned tasks create in
SAS/Connect or Integration Technologies spawners on z/OS, in WLM
(WorkLoadManager) you should establish the various service classes
for USS (Unix System Services) (i.e. OMVSLO, OMVSMED, OMVSHI).
In the USS shell script for SAS/Connect or Integration Technologies, set
the environment variable _BPX_ACCT_DATA to one of the WLM service
classes.

Example of lines to add to the USS shell script:

#
#  Use the account data to place SAS in the correct WLM service class
#
export _BPX_ACCT_DATA=OMVSMED

The spawned processes are under control of OMVS workload.

NOTE: This also applies to the Intelligence Platform Servers
   (Workspace, StoredProcess, Connect)
