Hi All,
I have spent the last week going through the setup of our cluster
configuration, and I think I might have an issue with its
configuration
and
need your help in rectifying it.
Ok here is a little bit of history... The system has been running
absolutely
fine for quite some time and we have been seeing issues only
lately. The
current configuration is:
1. Two servers - each running JBoss 4.2.2
2. Jackrabbit JCA has been deployed on each node. The
applications access
JCR via JNDI / RMI lookups
3. Each instance has its own home directory, but the workspace
content is
on
a shared NAS.
4. The repository uses a hybrid of FileStore and DBStore
(information
available in the files)
Now, for some time I keep having occasional issues of content being
available from one node and not being available from another
node. I keep
seeing exceptions like:
Caused by: javax.jcr.RepositoryException: failed to resolve name of

From all the reading that I have been doing, I am guessing this
is a case
of
broken search indexes (please correct me if I am wrong). If that
is the
case, then how do I go about cleaning up this mess? I guess I am
extreme
novice and am not sure about the guy who set this up in the first
place,
but
any help on this front would be greatly appreciated.
Thanks,
Rogue
p.s.: Sorry for the HTML mail.
