Session EJB no pooling in WildFly 9.0.2.final --------------------------------------------- Key: WFLY-6506 URL: https://issues.jboss.org/browse/WFLY-6506 Project: WildFly Issue Type: Bug Components: EJB Affects Versions: 9.0.2.Final Reporter: Ralph Soika After doing some perfomance tests on wildfly 9.0.2.final I recognized that stateless session ejbs are no longer pooled even if the pool settings in standalone.xml are correct. See the following example : {code:java} <subsystem xmlns="urn:jboss:domain:ejb3:3.0"> <session-bean> <stateful default-access-timeout="5000" cache-ref="simple" passivation-disabled-cache-ref="simple"/> <singleton default-access-timeout="5000"/> </session-bean> <pools> <bean-instance-pools> <strict-max-pool name="slsb-strict-max-pool" max-pool-size="32" instance-acquisition-timeout="5" instance-acquisition-timeout-unit="MINUTES"/> <strict-max-pool name="mdb-strict-max-pool" max-pool-size="20" instance-acquisition-timeout="5" instance-acquisition-timeout-unit="MINUTES"/> </bean-instance-pools> </pools> ....... {code} This issue is also discussed in wildfly forum: https://developer.jboss.org/message/954200#954200 In Widfly 8.0 there was the configuration missing. Now the configuration is added. But it had no effect.
