HPUX : MWA startup troubleshooting

If MWA is not working, MeasureWare processes "scopeux", "perflbd" and "midaemon"

1. run "mwa start", after that check whether all monitored
MeasureWare processes are running:


# mwa start
# ps -e | grep -e scopeux -e perflbd -e midaemon

You should see the output like this :

20948 ? 0:00 perflbd
20940 ? 0:00 scopeux
20937 ? 0:00 midaemon

If you can see "perflbd","scopeux" and "midaemon" processes in the output, stop
here.

If you can not see any of the 3 processes, go to the following steps.

2. Stop all MeasureWare process

1). stop measure process

# mwa stop

2). stop ttd process

# ttd -k


3). Sometimes the above 2 steps can not stop all measureware processes.
Verify this with command "ps -ef grep /opt/perf", if any measureware
processes still running, kill them.

For example :

# ps -ef |grep perf
root 1657 1 0 Apr 15 ? 124:28 /opt/perf/bin/perflbd
#
# kill 1657

If the above "kill" command can not kill the process, please try it with
option "- 9"

# kill -9 1657

3. backup all performance data

For example :


# mkdir /var/adm/perf/datafile/old_logs

cp -p /var/opt/perf/datafiles/logappl /var/adm/perf/datafile/old_logs
cp -p /var/opt/perf/datafiles/logdev /var/adm/perf/datafile/old_logs
cp -p /var/opt/perf/datafiles/logglob /var/adm/perf/datafile/old_logs
cp -p /var/opt/perf/datafiles/logindex /var/adm/perf/datafile/old_logs
cp -p /var/opt/perf/datafiles/logproc /var/adm/perf/datafile/old_logs

or you can backup the above files to some other directory you want to.

If the log files are too huge, please also gzip the backup files.

4. Zero-size all performance data

> /var/opt/perf/datafiles/logappl
> /var/opt/perf/datafiles/logdev
> /var/opt/perf/datafiles/logglob
> /var/opt/perf/datafiles/logindex
> /var/opt/perf/datafiles/logproc

5. Start MWA again

# mwa start

6. Ensure all monitored process are running :

# ps -eaf |grep -e scopeux -e perflbd -e midaemon ; date

You should see the output like this :

20948 ? 0:00 perflbd
20940 ? 0:00 scopeux
20937 ? 0:00 midaemon

If you can see "perflbd","scopeux" and "midaemon" process in the output,
you are good here
