BALANCE
BALANCE optimizes overall performance by balancing among CPU time, sort elapsed time, and I/O activity to SORTIN, SORTOUT and SORTWK. If you want to emphasize one performance measure at the possible expense of others, use CPU, ELAP, or IO. See CPU, ELAP, and IO, below. Note that these options and BALANCE are all mutually exclusive.
ENHANCED
When ENHANCED=YES, MFX collects enhanced trace data and prints it to a dynamically allocated $ORTDIAG file if there is a qualifying event such as an ABEND (except B37, D37, E37, 04E, 13E or 722), or when a memory message (WER039A, WER153A, WER314A, WER391A) is issued.
When ENHANCED=NO, MFX does not collect enhanced trace data.
When ENHANCED=FORCE, MFX collects enhanced trace data and prints it to a dynamically allocated $ORTDIAG file in any case.
