FILE:             Batch User Activity
SAS FILE NAME:    DETAIL.BATPGM01
SOURCE LOCATION:  prefix.MICS.USER.SOURCE(DYSMFEXC)

SEVERITY:  Impacting            (SEVERITY='I')
MANAGEMENT AREA:  Workload      (MGMTAREA='WORKLOAD')

PURPOSE:  Identifies steps with excessive disk mounting
activity.

RATIONALE:  The mounting of a disk volume is both time
consuming and efficiency impacting.  Where possible, you
should consider online storage as an alternative,
particularly for small, frequently used data sets.  In
addition, you should review job control statements to
determine whether all the mounts are necessary.

DEFINITION:  This exception is detected when the number of
disk mounts exceeds the installation-defined value.

EXCEPTION STATEMENTS:  The SAS statements identifying the
exception situation and describing the condition are stored
in the source member named in SOURCE LOCATION and are
described below.

THRESHOLD MODIFICATION:  Modify the value used for mounts as

       appears as:

          WORK > 2
