> When configuring number of MDBs concurrently processing messages, two parameters needs to be considered
>   *  mdb-strict-max-pool - The number of MDB instances available to concurrently receive messages from the JCA RA's sessions - configured in EJB subsystem
>   *  maxSession - The number of sessions the JCA RA can use concurrently to consume messages - configured by MDB Activation config property
> Maximal number of concurrently processed messages equals to minimal value of these parameters.
> In case number of MDBs needs to be adjusted, admin needs to update/check both parameters (located in different places)
> It would be nice to align size of mdb-strict-max-pool and maxSession activation config property.
> If maxSession is not specified, size of mdb-strict-max-pool should be used.
> *Admin story* : because of performance reasons, I need to tweak number of concurrently running MDBs. Now I need to configure two separate parameters located in different places, and in large majority of cases it is best to set them to same value
