Stateless Session Bean pooling

[ktfan]

By default the slsb-strict-max-pool is set to slsb-strict-max-pool="20", is it the recommended maximum pool size ?

Is there a way to check the number of "live" session bean instances ? I dont see such a feature in the Admin management console.

It's not a recommended size, since each bean in each application would have to tune it accordingly. It's just a default value we setup.

I don't think it's available since the metrics aren't exposed yet. There's some work going on for this here https://issues.jboss.org/browse/AS7-2281

What if I set the slsb-strict-max-pool to a high number, say 1000 to be sure many concurrent request may be run at same time ?

That would depend upon what your slsb is doing. Is it performing database access? Do you have access to 1000 database connections?

[shidani]

So in case of performing database access the slsb-strict-max-pool should be less than or equal to max-pool-size of datasource. is it right?

Yes and no,

yes if you do not want to wait for a DB connection.

no if you can accept to wait for the 'blocking time'

but this depend to the application whether the datasource is used the whole time and how long it is.

It make not a big sense to have lots of getConnection timeouts in the logfile.
