Queue Entry States
wt.queue.queueGroup=localhost in each wt.properties file sets up three queue
groups named appsvr1, appsvr2, and appsvr3.
Also, you can set the default queue group to map to another established group by
setting the wt.queue.queueGroup.default property. For example, setting the
following properties in the wt.properties file on the method server that resides on
the appsvr2 host sets the queue group appsrv2 and maps the default group of
queues to the group named appsvr1. Additional queues are mapped to appsvr2
and appsvr3:
wt.manager.monitor.start.BackgroundMethodServer=1
wt.queue.queueGroup.default=appsvr1
wt.queue.queueGroup=localhost
wt.queue.xxx=appsvr2
wt.queue.yyy=appsvr2
wt.queue.zzz=appsvr3
You can change the group to which a queue is assigned by changing queue
properties through the Queue Manager utility.
Each entry in a background queue corresponds to a processing task. An entry can
be in one of the following states:
State Description
Ready Corresponds to the initial state of the task. Only entries in the
Ready state are selected for execution, based on the order in
which they were inserted into the queue (first in, first out).
Suspended Indicates that an entry is to remain in the queue, but is not
eligible for execution until you change its state to Ready.
Changing a state can be accomplished from the Queue
Manager tab in the System Configurator.
Executing Indicates that an entry is selected for execution. From the
Executing state, the entry goes to either the Completed or
the Failed state.
Completed Indicates that the task was successfully executed. You can
purge queues of Completed entries so that the size of a
queue does not exceed the storage capacity of the database.
Failed Indicates that an error occurred during execution. You can
purge queues of Failed entries so that the size of a queue
does not exceed the storage capacity of the database.
