Hi all,
I want to ask if API of workflow use mechanism like connection pool to handle connection with workflow server. For example when I use method logon2 is API will use new connection with server or will check if there connection available and use it. I handled this problem programming by 80%. But I wonder if workflow uses this mechanism
thanks.

Hi,

MQWF has a 'session' concept. A session is represented via an ExecutionService object. Each execution service has established exactly 0 or 1 session to the server at one time. A program can re-use an execution service to establish a new session with a different userID but only one at a time. So there is no connection pooling here. It is a 1:1 relation between execution service and a session.

Under the covers however a session is using MQ connection(s). And these connections may use connection pooling. But this is infrastructure from the viewpoint of MQWF.
