Hi guys
I am facing a problem when trying to get the state from cache in a 2-clustered cache
enviroment. What a I get from the node which is starting and trying to get the state from
another node in the cluster is:
2008-03-10 11:01:20,630 WARN [org.jboss.system.ServiceController] Problem starting
service jboss.cache:service=ServicesDataCache
| org.jboss.cache.CacheException: Initial state transfer failed: Channel.getState()
returned false
As I saw in http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossCacheTroubleshooting I
increased the InitialStateRetrievalTimeout parameter in the cache configuration file and
everything worked fine.
Then, I wanted to test setting the parameter FetchInMemoryState to false so I could test a
different solution (in my case, I do not care using a cold loading cache) What I got from
this test is that some cache attributes (around 55000) were transferred to the cache that
is starting (there are around 90000 attributes in the other node)
Perhaps, I am missing some configuration parameter. I am using Jboss Cache 1.4.1.SP8 and
JbossAS 4.2.2.GA. Here is my cache config file:
