[rules-users] Two Guvnor instances sharing repository

[Demian Calcaprina]

Hi Guys,

I have two guvnor instances. They are using a mysql db repository. I would
like both to point to the same database.

I configured them both to use the same database in the repository.xml, but
it starting throwing errors and they were not in sync.

Errors are like this

... 13 more

I also tried both instances to also share the repository folder, both this
is failing because it lockes the file
Caused by: javax.jcr.RepositoryException: The repository home
/home/calcacuervo/development appears to be in use since the file named
.lock is locked by another process.

org.apache.jackrabbit.core.util.RepositoryLock.tryLock(RepositoryLock.java:166)


Any idea on how could I do it?

Thanks!
