----------------------
> Failover Mechanism not working with Remote Auxillary Cache
> ----------------------------------------------------------
>
> Key: JCS-192
> URL: https://issues.apache.org/jira/browse/JCS-192
> Project: Commons JCS
> Issue Type: Bug
> Components: RMI Remote Cache
> Affects Versions: jcs-1.3, jcs-2.2
> Reporter: Amol D
> Priority: Critical
> Attachments: StackTrace.txt
>
>
> Currently we are using RMI Remote caching and individually i can connect to
> both the servers indiviadually for example in client if i set
> jcs.auxiliary.RFailover.attributes.FailoverServers=127.0.0.1:5556
> or
> jcs.auxiliary.RFailover.attributes.FailoverServers=127.0.0.1:5555
> then caching works fine
> Further i connect my l client to both the servers as below
> jcs.auxiliary.RFailover.attributes.FailoverServers=127.0.0.1:5556,127.0.0.1:5555
>
> In this case whenever i cache it always gets added to Primary Server
> (127.0.0.1:5556) and in case Primary server goes down Caching should be based
> on Failover server (127.0.0.1:5555) however it is not happening . In case
> Primary goes down client gets a connection to secondary server
> (127.0.0.1:5555) is made as per below logs
> 12:42:32.748 [main] INFO
> org.apache.commons.jcs.auxiliary.remote.RemoteCacheManager - Looking up
> server
> [//127.0.0.1:5555/org.apache.commons.jcs.engine.behavior.ICacheServiceNonLocal|https://issues.apache.org/127.0.0.1:5555/org.apache.commons.jcs.engine.behavior.ICacheServiceNonLocal]
> 12:42:32.783 [main] INFO
> org.apache.commons.jcs.auxiliary.remote.RemoteCacheManager - Server found:

> -6827216959955041134]]]]]
> However when i add a new element to JCS Cache in this case it is not
> reflected so failover seems to be not working as there are no memory hits .
> Attaching a StackTrace of log from client please provide a fix for this
> Similar behavior is seen even with JCS 1.3 version
