Hey all,
I'm struggling to get my remote cache working correctly. My clients can
connect and add listeners to my remote cache server, but my remote cache server
is not publishing any events when a change is made to any of that server's
caches. I think this may be because when the remote cache servlet starts up,
it looks like it parses the cache.ccf file for any existing cache regions to
listen to. With my config, there are none pre-defined. I always use the
default region to create my caches dynamically. I need some way for these
dynamic caches to publish change events to my remote cache server so it can, in
turn, publish those events to my clients.
I've tried such things as adding a Remote Cache to my server's default config
that's connected to the remote cache server at localhost where GetOnly is false
and Receive is false, but have always gotten errors on startup - maybe I was
just configuring it wrong? I've also tried programmatically getting the remote
cache manager whenever I create one of my dynamic disk caches and adding a
listener. This worked for publishing updates, but gets/puts no longer worked.
Thanks in advance for any help or guidance you can provide. My client and
server cache.ccf files are below. If any code I'm using would be helpful, let
me know and I'd be happy to provide it.
