According to this JBoss EAP 5 (JBoss AS 6) documentation: 根据这个JBoss EAP 5（JBoss AS 6）文档：
https://access.redhat.com/site/documentation/en-US/JBoss_Enterprise_Application_Platform/5/html/Performance_Tuning_Guide/sect-Performance_Tuning_Guide-Message_Driven_Beans.html https://access.redhat.com/site/documentation/en-US/JBoss_Enterprise_Application_Platform/5/html/Performance_Tuning_Guide/sect-Performance_Tuning_Guide-Message_Driven_Beans.html
You need to take care of two concepts 你需要处理两个概念
- Pool Size: This pool is named StrictMaxPool and the default values is 15. It must be configurated on JBoss config files (read link) 池大小：此池名为StrictMaxPool，默认值为15.必须在JBoss配置文件上配置（读取链接）
Session Size: This is the parameter configured according to the standard with the following annotations:
会话大小：这是根据标准配置的参数，带有以下注释： @ActivationConfigProperty(propertyName="minSessions" , propertyValue="25") @ActivationConfigProperty(propertyName="maxSessions" , propertyValue="50")
Where minSession and maxSessions are the number of instances created by JBoss. 其中minSession和maxSessions是JBoss创建的实例数。 But if the StrictMaxPool is set to 15 then you cannot create more than 15 instances although you configure maxSessions to 50 但是，如果StrictMaxPool设置为15，那么虽然您将maxSessions配置为50，但您无法创建超过15个实例
For JBoss EAP 6 (JBoss AS 7) the pool is named mdb-strict-max-pool and their default max pool size is 20. 对于JBoss EAP 6（JBoss AS 7），该池名为mdb-strict-max-pool ，其默认最大池大小为20。
