IBM 4J manual Wait Queue, Element Comment, Status Comment

Page 46

After a Process successfully completes, it is automatically deleted from the Execution queue. A flush process command with hold=yes moves a Process from the Execution queue and places it in the Hold queue. When a session is interrupted, the Process moves from the Execution queue to the Timer queue if retry values are specified. If connection is not made before the retry values are exhausted or if retry values are not specified, the action taken depends on the conn.retry.exhaust.action parameter. By default, the Process moves to the Hold queue.

The following table shows the status values for the Execution queue:

Element

PE

EX

Comment

Pending Execution is the initial queue status when a Process is submitted with maxdelay=0.

Execution status indicates that the Process is executing.

The Wait Queue

Processes in the Wait queue are waiting for a new or existing connection to become available between the local node and the remote node.

Processes can come from the Hold queue or the Timer queue. Processes also can be placed in the Wait queue by a submit command with no parameters specified, submit with retain=no, or submit with hold=no.

After the connection is made, Processes automatically move to the Execution queue.

The following table shows the status values for the Wait queue:

Status	Comment

WC	This status indicates the Process is ready to
	execute as soon as possible, but no session is
	available. Other Processes may be executing
	with the SNODE, and no other sessions are
	available. This Process runs as soon as a
	new session is created or an existing session
	becomes available.

WR	This status indicates that the Process is in
	retry status. The number of retries and
	intervals between retries is specified in the
	network map.

WA	This status indicates the initial queue status
	when a Process is submitted without a hold
	or retain value. This Process is ready to
	execute as soon as possible.

WS	This status indicates that the Process is
	waiting for the PNODE to continue the
	session.
