Re: [foxboro] Operator Action Journal


Yes the entries can be increased to 9999, but there are some problems
(not-documented) associated with that.

Once upon a time we were using 9999 operator action & 999 system monitor
messages. But what happened was once in a while, say after every half hour
or so, the AW idle time used to goto zero. The culprit was sqlturbo eating
more than 80% of cpu time.

Then it came from this list as well as Foxboro that Legacy Historian has
some problems in handling these many messages.

So probably you could observe your CPU loading for a couple of hours & if
it's fine, it's fine.

If you would do a search for "0% Idle Time On AW51B" you will find the
links to the archive on Cassandra for the previous discussions on the
subject. There is one mail in particular by Mr. Stephen written on April
19, 2002 that discusses quite a lot.

Why do you say it saves only 500 entries? I'm still using the legacy
historian, and the configurator allows me 4 digits for the Maximum Number
of
Messages so I put in 9999 for the opraction message group.

Here's a snippet of my script to grab things out of the OAJ. You'll have to
come up with the $YY, $MM, and $DD variables yourself (man date), but this
is the basis for what you want to do. Change the start and end time for the
second daily execution.

HIST=hst04a                          # change to the proper historian
OAJGEN=/usr/foxbin/oajgen            # the Ace report script
TMPFILE=/tmp/oajtempfile             # temp output file
STRTIME="$YY-$MM-$DD 00:00"          # start time is 00:00 today
ENDTIME="$YY-$MM-$DD 11:59"          # end time is 11:59
# run the Ace report job to produce the report
$OAJGEN $TMPFILE $HIST '*' '*' '*' "$STRTIME" "$ENDTIME"
