Hi all;
i have implemented an integration message flow in two scenarios as follows :

Quote:

Scenario 1 :
TCPIPSERVER INPUT => TCPIPSERVER RECEIVE => TCPIPSERVER OUTPUT

Quote:

Scenario 2 :
TCPIPSERVER INPUT => TCPIPSERVER RECEIVE => CICSREQUEST => TCPIPSERVER OUTPUT

The WMB runtime and CICS server are both at the same machine.
Also suppose there is some compute nodes between the above nodes but the main consideration is this :
There is a client mutithread application pomping messages to the socket server flow (TCPIPSERVERINPUT node). When looping back to itself, i mean when there is no CICSREQUEST node available (Scenario 1) , the Client makes as many socket as it needs and the resource statistics shows that the TCPIPSERVER nodes have the same open connections as the client needs. But when i participate the CICSREQUEST node (Scenario 2) , the open connection shown by the TCPIPSERVER nodes in the resource statistics does not satisfy the client and it has variable behaviour. If i could open 100 concurrent sockets in the previous scenario, in this case it falls down to 13~17 open connections. The cpu has 40~50 %idle time and there is a total memory of ~1.5GB free.
The TCPIPSERVERINPUT node uses the pool associated with message flow. The JVM uses a total memory of 43MB (19MB for heap and the remainder for non-heap memory). Do i have to do anything for the connection manager in the execution group? please help me.
