Hi,
I'm trying to get Terracotta working to cluster my Lucene
RAMDirectory index while using the Compass/Lucene Grails plugin. I've
dug into compass to find that it manages the RAMDirectory objects in
this class: org.compass.core.lucene.engine
.store.RAMLuceneSearchEngineStore and manages each subindex RAMDirectory in a java.util.HashMap called ramIndexes.
I've been trying to set
org.compass.core.lucene.engine.store.RAMLuceneSearchEngineStore.ramIndexes
as a root in Terracotta (I'm a rookie here!), but no matter what I do I
can't get past the UnlockedSharedObjectException exception. I've tried
using coarse named locks though I'm not sure if I'm setting it up
directory. I thought I'd ask here first...
Is it possible to have this as a root and have Terracotta
manage it if the code around it is not synchronized and the data
structure (HashMap) is not synchronized? If so can you point me to how
to configure it? I've tried already on my own for five hours to get it
working but just can't get past it.
Thanks!
Mike
