[JBoss Cache: Core Edition] - TCPCacheServer
by lovelyliatroim
Hi Guys,
Was just looking at how this works in the 2.2 version. One thing that struck me when looking at it was that i didnt see the clean up of the at the end of the run method. Maybe its getting called from outside the package but just thought i would mention it cause everything looks to be encapsulated in this class
So heres the run
|
| public void run()
| {
| int op;
| Fqn fqn;
| Object key, val, retval;
| NodeSPI n;
| boolean flag;
| ...........
| }
| output.flush();
| }
| catch (Exception e)
| {
| log.debug(e, e);
| try
| {
| output.writeObject(e);
| output.flush();
| }
| catch (IOException e1)
| {
| log.error(e1, e1);
| }
| }
| }
|
Now was just curious of where the clean up happens, where/who is calling the close() ??
Might be something, might be nothing but was just curious!!
Thanks,
LL

[JBoss Messaging] - Re: High volume usage patterns and best practices

To date I have followed the samples included with JBoss Messaging and am creating a new connection+session+temp_response_queue on a per request basis. It was suggested that some of this is actually an anti-pattern.

Yes, that would certainly constitute an anti-pattern

I fairly quickly run out of memory, and get a 25+% failure rate even at low volumes. I am inclined to believe it is in part due to the way in which I am accessing the queue's and topics.

| I would like advice on the best way to handle the "pooling" of some of these objects (connections and sessions) for reuse. Is this advisable at all? If so, is there solution examples anyone is aware of? I would hate to have to create my own pooling logic with all the inherent issues in high volume systems.

You should have a look at the wiki, docs etc, this is a very common question.
