How Do Processes Work?
The following illustration shows how a Process executes:
The following explains the Process steps:
|Process submitted||A user submits a Process from a IBM® Connect:Direct® Process library or from the Connect:Direct Browser User Interface.|
|Process syntax parsed||The parser within IBM Connect:Direct verifies the Process syntax.|
|Process sent to Transmission Control Queue (TCQ)||If the Process passes syntax checking, it is placed
in the appropriate work queue according to Process parameters, such
as priority, class, and start time. The IBM Connect:Direct work
queues are jointly referred to as the TCQ. A Process is in one of
the following states in the TCQ:
A queued Process can be queried and manipulated through IBM Connect:Direct commands such as SELECT, CHANGE, DELETE, FLUSH, and SUSPEND PROCESS. For complete information on the IBM Connect:Direct commands and the various queues, refer to the user guide for your platform.
A message indicating that the Process was submitted successfully is created when the Process is placed into the TCQ. The Process statements have been checked for syntax, but the Process may not have been selected for execution.
|Process Executes||The Process is selected for execution based on Process parameters and the availability of the SNODE.|
