MCU/Main Memory Overview
PARM=2 Causes the current contents of MEMLOG to be printed on the
output device after which the file is deleted from the
system. (This is the only way to remove the MEMLOG file
fram the system and normally only the system manager would
use this PARM value.)
MEMTIMER (MEMTIMER.PUB.SYS) is the utility program which allows
the user to modify the interval of time between successive memory
log updates. The normal default interval is 60 minutes. This
interval provides the average installation with an adequate log
of the memory system. For other reasons, it may be desirable to
modify the interval to allow increased monitoring of the memory
per formance. It is the function of MEMTIMER to modify the time
interval. MEMTIMER alters the current timing interval to a new
value and terminates the current interval. This causes MEMLOGP
to update the memory log file immediately and periodically
thereafter according to the new interval specified. A new timing
interval is specified through the PARM parameter of the RUN com-
mand. There is no user dialogue with MEMTIMER. The PARM value
is given as a positive integer greater than zero which represents
the number of seconds between log file updates. To begin memory
logging at 10 second intervals, the following RUN command would
be entered:
:RUN MEMTIMERiPARM=lO
To return logging to the default interval (60 minutes), the fol-
lowing
RUN
command would be entered:
:RUN MEMTIMERiPARM=3600
Three error conditions are detected by MEMTIMER. If the PARM
pararne ter of the RUN command is equal to or less than zero, then
MEMTIMER will terminate after printing the following message:
**
INVALID PARM (DELAY) VALUE
**
The current time interval remains unchanged.
If MEMLOGP has been terminated, then MEMTIMER will terminate it-
self after printing:
**
MEMORY LOGGING PROCESS NOT ACTIVE
**
In this case there is no timing interval update.
If MEMLOGP is currently updating the memory log file, the follow-
ing message will appear:
**
MEMLOGP TIMER ENTRY NOT FOUND
**
In this case, the timing interval will be updated. MEMTIMER
should be run again to ensure that MEMLOGP will recognize the
updated interval immediately. Note that the default timing in-
terval will become the current timing interval each time the sys-
