1. Use INDI:ATE LOAD to display system load conditions.
2. Use INDICATE USER to display the total amount of certain resources
used by your virtual machine durinq the current terminal session. Use the INDICATE USER command before and after the execution of a pLogLam to indicate the execution characteristics of that program
in teLms of the resources used. 01-nn Q2-nn STORAGE-nnn% RATIO-nn.n is a smoothed value that indicates the percentage of time

INDICATE STORAGE-nnn% RATIO-nn.n is a measurement of the use of real storage. It is a
smoothed ratio of the sum of the estimated working sets
of the users in queue 1 and queue 2 (the runlist) to the
number of paqeable pages in the system, expressed as a
percentage. Because the criterion for allowing a user on
the eligible list to enter a queue is that at least 15
percent of his working set size must fit in the available
page frames, the value of STORAGE can be more than 100 percent.
indicates the scheduler contention ratio; RATIO is a
smoothed measure of the contention for real storage, and
is defined as RATIO=(E+M) 1M. M is the number of users in
queue 1 and queue 2 (the runlist), and E is the number of
users waiting to be allocated real storage by the
scheduler and, therefore, temporarily resident in the
scheduler's eligible lists. Thus, RATIO is the ratio of
active users to users being serviced, and is 1.0 for
optimum response. Optimum response occurs when enough
storage is available to accommodate all active users,
assuminq the processor can process their commands. If E
and M are both 0, the value of RATIa is set to 1.0. Values of FATIO=1.5 and M=10 mean that users are in the
eligible lists waiting for the scheduler to allocate real
storage to them, and that the full discrimination ability
of the biased scheduler may be exercisea upon them. PAGES: RES-nnnn WS-nnnn READS=nnnnnn WRITES=nnnnnn DISK-nnnn DRUM-nnnn VTIME=mmm:ss TTIME=mmm:ss SIO=nnnnnn RDR-nnnnnn PPT-nnnnnn PCH-nnnnnn
