Problem: WO application instances deployed via JavaMonitor (JM) are

Troubleshooting: Restarting the servers does nothing.
Within JM, deleting the configured application and re-configuring each
instance does nothing. The app instances are still unable to turn ON.
Running the apps via terminal works. Hence, the frameworks and woa
files are
not the issue.
Current Solution: The above behaviour indicates that there is a
problem with Java
Monitor's configuration file; SiteConfig.xml. This file is located in
/Library/WebObjects/Configuration/SiteConfig.xml. I hesitate to say
that the
file is corrupt because it can be opened and the config details appear
correct. However, deleting this file, restarting JM and
reconfiguring each
app and their instances solves the problem.
This solution is not ideal since you must manually reconfigure each
and
every app - which is painful if you have over 5 apps and 15
instances to
configure.
I don't know why/if SiteConfig.xml is getting corrupted, but it might
be worthwhile to do the following:
1) set things up in JavaMon as you'd like it
2) copy SiteConfig.xml to SiteConfig.xml.bak
3) next time you think SiteConfig.xml is corrupted, diff it against
this backup copy: diff SiteConfig.xml SiteConfig.xml.bak
That will at least show you the differences.
However, it seems unlikely that it is getting corrupted. Is there
anything useful in /var/log/webobjects.log?
