system.queueParallelism.maxReceivers overides maxconcurrency in JDBC Receiver

All,

I tested one EOIO interface proxy to JDBC (SQL DATABASE).

Sceario 1: system.queueParallelism.maxReceivers 15

max concurrency 1

Java Nodes 4

JDBC_http://sap.com/xi/XI/SystemRecv 15.

Only the above mentioned interface is executed in teh environment. I know settings max receivers to 15 and JDBC System Recv to 15 as well does not make sense, neverthless I wanted to test the system the way it is handed over to me.

Result: I see 60 delivering messages at the same time i,e 15 System Recv threads on each node are being utilized fully.

Scenario 2:

system.queueParallelism.maxReceivers 15 

max concurrency 6

Java Nodes 4

JDBC_http://sap.com/xi/XI/SystemRecv 15.

Result: still the same result. No effect of changing max concurreny.
