[JBoss Cache: Core Edition] - Re: What is the definition of Node in treecache? Passive?

by bstansberry＠jboss.com

Perhaps the eviction thread is not running frequently enough? The maxNodes config is not a hard limit, i.e. the cache doesn't use the thread trying to insert node 30,001 to evict a node first in order to stay under the limit. There's a separate eviction thread (runs every 5 secs by default) that does it. That said 97,000 versus a limit of 30,000 is a big difference.

[Performance Tuning] - Re: JBoss Performance Problems with SPECjAppServer2004

by PeterJ

We have run specjappserver with injection rates in the high hundreds, using MySQL as the database, so it is possibly. How many connections are you allowing in MySQL? Both the database and the *-ds.xml file must agree on the max number of connections, and I recommend setting both min and max connections to the same value. Also, I think that you need to set close you the IR*8 because each request will need a connection. Also, have you seen: http://www.jboss.org/community/docs/DOC-11980 http://www.jboss.org/community/wiki/SPECjAppServer2002 View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4224099#4224099 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4224099

[JBossWS] - Re: Error in Invoking Webservice

by PeterJ

And you didn't do a search of the forums on "setProperty"? If you did, you might have found various posts like these: http://www.jboss.org/index.html?module=bb&op=viewtopic&t=152460 http://www.jboss.org/index.html?module=bb&op=viewtopic&t=147781 http://www.jboss.org/index.html?module=bb&op=viewtopic&t=102355 (my take on why this happens is on the second page) Basically - you are JDK6 but you did not download the JDK6-variant of JBoss AS.

[JBoss Cache: Core Edition] - Re: What is the definition of Node in treecache? Passive?

by yangju

Well, sometimes we see in production that the total number of objects cached is far more than what we defined for max node number in treecache.xml. We deploy hibernate session factory as mbean and turns on the session factory statistics so we can watch all the caching behavior. In one particular case, the max node in the treecache.xml is 30,000 but we saw the total objects cached is 97,000. The jvm eventually got outofmemory error and we had to restarted jboss. Althought this is rare case, we constantly observe that the total number objects cached outnumbers the max node number by a small amount. Is this expected behavior? Why tree cache does not follow the max node that we defined? Thanks.

[JBoss Cache: Core Edition] - Re: Resource cleanup upon eviction -- change in behaviour in

by bstansberry＠jboss.com

The EJB3 SFSB caching code does something similar to what you describe with 1.4. See the nodePassivate method in [1] (it's inside the ClusteredStatefulCacheListener inner class). The technique used there was added in direct response to the issue you report [2]. Summary of what it does: 1) Use a CacheListener; you're right, it's less hacky. 2) Use TreeCache's public DataNode peek(Fqn fqn) not public Object peek(Fqn fqn, Object key). The latter calls into the interceptor chain causing your problem; the former does not. 3) Once you have the DataNode you can call DataNode's public Object get(Object key). This is all hacky, but...
