MWA log files not used

[Todd McDaniel_1]

I have a DBA trying to run a command and is getting an error. I have no idea what to do. I created the file logproc and restarted MWA but no avail.

See the error below with the Process parm.

======================

We are using this command but it failed because it cannot open file (in red color).
This works on all servers except chTcfas1.
Do you have any idea what is causing the problem?

Hi Todd,

What does
mwa status
respond with?

Make sure the scope, background daemon & server status entries all have valid PIDS.
Make sure you have at least 1 running rep_server if you have other servers collecting that data.

If there's a problem with one of the services, then check /var/opt/perf/status."service_name" for clues.

HTH,
Jeff

To expand on that...

One of the common problems that MWA encounters is that one of the log* files becomes corrupted & the only way to recover is to stop MWA, cp the file out and/or null it & then restart MWA - checking the status file will show the problem as well as tell you whether the restart was successful or not.

HTH,
Jeff

I have had issue's starting individual agents within mwa.

you can check /var/opt/perf/

then the process' that start have a status log

also in /var/opt/perf/datafiles there are logproc logappl logdev logtran logglob files that can become corrupt - this should be detailed in the status logs

[Todd McDaniel_1]

Are those files automagically created?

If I move out hte file will it be recreated or do I need to touch it?

[Todd McDaniel_1]

I found the problem...

The line that looks like this:

log global application process device=disk,lvm


Didnt have the word "process" in it.... once I stoped the mwa agent, and added it, the file was created.
