Air Cleaner User Manual

Note: You cannot set INDXTYPE to MSGTOKEN if:
v The queue is a model queue with a definition type of
SHAREDYN
v The queue is a temporary dynamic queue
v The queue is a transmission queue
v You specify QSGDISP(SHARED)
If altering or replacing an existing nonshared queue, the INDXTYPE
parameter can be changed to NONE, MSGID, or CORRELID at any time,
and the change takes effect immediately if all the following conditions are
satisfied:
v No applications have the queue open
v The queue is empty
v There are no uncommitted MQPUT or MQGET calls outstanding
against the queue
If these conditions are not satisfied, the parameter is changed immediately,
but the index is not rebuilt until the next time the queue manager is
restarted. The reply sent by the queue manager indicates if this is the case.
This parameter can be changed to MSGTOKEN only when there are no
messages on the queue. If you attempt to change this parameter to
MSGTOKEN while there are messages on the queue, the command fails.
For local queues defined with a disposition of SHARED, the INDXTYPE
parameter can be changed to NONE, MSGID, or CORRELID only if all the
following conditions are satisfied. If these conditions are not satisfied, the
command fails.
v No applications have the queue open
v The queue is empty
v There are no uncommitted MQPUT or MQGET operations outstanding
against the queue
This parameter is supported only on OS/390. On other platforms, retrieval
optimization might be provided, but it is not controlled by a queue
parameter.
INITQ(string)
The local name of a local queue (known as the initiation queue) on this
queue manager, to which trigger messages relating to this queue are
written. See “Rules for naming MQSeries objects” on page 4.
This parameter is supported only on local and model queues.
LIKE(qtype-name)
The name of a queue, whose parameters will be used to model this
definition.
This parameter applies only to the appropriate DEFINE Queue command.
If this field is not filled in, and you do not complete the parameter fields
related to the command, the values are taken from one of the following,
depending upon the queue type:
