Subject [jira] Resolved: (OPENJPA-945) Cache synchronizing in multipele javm on single machine
Date Thu, 17 Feb 2011 04:18:24 GMT


Michael Dick resolved OPENJPA-945.

    Resolution: Won't Fix

I'm afraid we don't have access to the kodo RemoteCommitProvider, and can't fix any issues
with it. 

If you can reproduce with OpenJPA's remote commit provider we can take a look, but for kodo
support you'll have to contact Oracle.

> Hi,
>       I am using two managed servers in a cluster in same machine.For Cache synchronization
across multiple JVM I tried to use the following settings in persistance.xml.
>   <property name="kodo.RemoteCommitProvider" value="tcp(Addresses=">
> But when i deploy this application into cluster in one of the manged server i am getting
a socket connection error.I think it is because of the two manged server in cluster is in
same mechine.Both server trying to listen on the same default port. I could able to make it
work when i used two managers in to different machine.But from the documentation i can not
figure out how i can configure TCP option for remote commit provider in the case of same machine
with multiple jvm. I also tried with
>     <property name="kodo.RemoteCommitProvider" value="wls-cluster"/>
>  this also work fine when they are in two different machine but not working when they
are in same machine.
>  I could not figure out the remote commit provider for multiple jvm and same machine.
> can anyone please help me.....
> thanks and regards
