Re: [foxboro] 0% Idle Time on AW51B


Thanks a lot. I mention one process as such as I picked up from
output of ps -ef.


root      12312     1  0   Mar 22 ?        0:00 
/opt/fox/hstorian/bin/reduction_ctl hist01
root      12313 12312  0   Mar 22 ?        0:01 /opt/informix/lib/sqlturbo root 
5.00.UD1


The other processes which have pid number same to that of ppid
of sqlturbo are as below:

hr_fetch, hist_srv, archiving_ctl, collect_mg, reduction_ctl

There are a total of 5 instances of sqlturbo running. I hope
this is the information that u asked for.


Thanks & regards

A sql_turbo process is being used by another process. You will first have
to
find out which one that is. So if you know the pid of the sql_turbo, find a
process which has this pid as ppid. It's in the field next to pid, when you
do a ps -ef. It's probably one of the historian processes. If you can tell
which process that is i'm more able to help you with this one.

Good Day


I have a AW51B running I/A Series software 6.1, with legacy Historian.

RAM on station is 96MB and swap space is 128MB.


Now the issue is that at certain times, the CPU idle time goes to 0% and
this phenomena is quite periodic, say around every 35-40 minutes for 10-15
minutes.

After going through the processes that were being executed at this instant
found that there is a process sql_turbo which eats upto 90% of the CPU
time.


Can anybody give me a idea what's going on.


Thanks & Regards
