Execution Queue | IBM 4J manual

The Execution Queue

Processes are placed in the Execution queue after Sterling Connect:Direct connects to the remote node. Processes normally come from the Wait queue, but also can be placed in the Execution queue by a submit command with maxdelay=0 specified.

Processes in the Execution queue can be in execution (EX) status or pending execution (PE) status. Processes with EX status are exchanging data between two Sterling Connect:Direct nodes. Processes with PE status are waiting for Process start messages to be exchanged between the local node and the remote node. Processes usually have PE status assigned for a very short period of time.
