Why RMI-IIOP?
Why use WMQ Workflow JAVA agent?
Performance? Scalability? JAVA-hungry?
Please advise!

haha, well , I should re-define my question.
Why not LOCAL_LOCATOR?
Why don't let MQ as a middleman in between App Server and MQWF?
Any good reason to use JNDI_LOCATOR?

For sure LOC locator policy can be used when the application server runs on a machine that has MQSeries installed.
This is the recommended locator policy - it uses MQSeries between the Application Server (acting as MQWF Client) and MQWF Server.
In this case the agent is local, embedded in the JNI layer (MQWF code is C/C++ based)

Only in cases when MQSeries is not available on the machine where the application server is running.
In this case the application server (acting as MQWF client) uses RMI over IIOP to communicate with a remote agent.
The Java agent can run either a different machine that has MQWF Client with Queue Manager or on the server machine.
Not recommended because the performance and scalability are not as good as the configuration using LOC locator policy. |

Thanks dsim, got it!
It means except money for MQ license and JAVA-hunger, no really good reason to use JNDI_LOCATOR. Right!

MQ license shouldn't be an issue: as i know MQWF comes with MQSeries licenses included for each 'Client with Queue Manager'.
