Hello,
I am getting following error in my application.
avax.ejb.ConcurrentAccessTimeoutException: No instances available in
Stateless Session Bean pool. Waited 30 SECONDS
at
org.apache.openejb.core.stateless.StatelessInstanceManager.getInstance(StatelessInstanceManager.java:226)

org.apache.openejb.core.stateless.StatelessContainer.invoke(StatelessContainer.java:204)

My application is heavily used. Looks like not enough instances of beans.
I saw this post to increase the pool size
https://tomee.apache.org/admin/configuration/containers.html
and changed my configuration as
java.naming.factory.initial=org.apache.openejb.core.LocalInitialContextFactory
openejb.deployments.classpath.ear=false
myApp = new://Container?type=STATELESS
myApp.AccessTimeout = 30 seconds
*myApp.MaxSize = 40*
myApp.MinSize = 0
myApp.StrictPooling = true
myApp.MaxAge = 0 hours
myApp.ReplaceAged = true
myApp.ReplaceFlushed = false
myApp.MaxAgeOffset = -1
myApp.IdleTimeout = 0 minutes
myApp.GarbageCollection = false
myApp.SweepInterval = 5 minutes
myApp.CallbackThreads = 5
myApp.CloseTimeout = 5 minutes
myApp.UseOneSchedulerThreadByBean = false
myApp.EvictionThreads = 1
On the server start up I see
INFO - Configuring Service(id=myApp, type=Container, provider-id=Default
Stateless Container)
DEBUG - Containers : 1
DEBUG - Type Container ID
DEBUG - STATELESS myApp
DEBUG - Deployments : 5
DEBUG - Type Deployment ID
/Question i have is /
How would i know if the bean size is increased ? I don't see any log
message for it.
/Secondly I also see /
DEBUG - Using default 'openejb.tempclassloader.skip=none' Possible values
are: none, annotations, enums, all or NONE or ALL
DEBUG - Using default 'AsynchronousPool.Size=5'
DEBUG - Using default 'AsynchronousPool.CorePoolSize=5'
DEBUG - Using default 'AsynchronousPool.MaximumPoolSize=5'
DEBUG - Using default 'AsynchronousPool.QueueSize=5'
DEBUG - Using default 'AsynchronousPool.KeepAliveTime=60 SECONDS'
DEBUG - Using default 'AsynchronousPool.AllowCoreThreadTimeOut=true'
DEBUG - Using default 'AsynchronousPool.QueueType=linked'. Possible values
are: array, linked, priority, synchronous
DEBUG - Using default 'AsynchronousPool.OfferTimeout=30 SECONDS'
DEBUG - Using default 'AsynchronousPool.ShutdownWaitDuration=1 MINUTES'
What's the AsynchronousPool ???
Please help me to sort this issue?
I'm running into this issues in production.
thanks
Kalyan
