CPU usage by threads started by infinispan?

[amalrajvinoth]

Dear all,

CPU usage by  threads started by infinispan ?

how to find out what are the threads currently running in ISPN?

i'm using following code.

it's looks like, the threads that are shown below are only from JGROUPS.

is it correct? if anyother way.pl let me know.

is it possible to reduce the no of threads?

          Thread.getAllStackTraces()

it gives following output in 2 node cluster having 2 caches instances one for repl, and another for invalidation.

node 1 (started first):

        No of current Alive Threads : 21

thanks.

Please someone answer the above Question & the below.

[1]. is the No of threads started by ISPN definite or it can be increased at runtime?

     what is the standard no of threads per cachemanager?

[2] . If I want to create namedcache programatically with custom config, How to do it?

thanks.

[amalrajvinoth]

Guys, please help me to find the answer for above Questions?

You can control the threads used by tuning the various executors.  See http://docs.jboss.org/infinispan/4.2/apidocs/config.html#ce_global_asyncTransportExecutor

Regarding creating named caches programmatically, see the API methods on EmbeddedCacheManager.
