AQ_TM_PROCESSES

Property	Description
Parameter type	Integer
Default value	None
Modifiable	`ALTER SYSTEM`
Range of values	`0` to `10`
Basic	No

AQ_TM_PROCESSES controls time monitoring on queue messages and controls processing of messages with delay and expiration properties specified.You do not need to specify a value for this parameter because Oracle Database automatically determines the number of processes and autotunes them, as necessary. Therefore, Oracle highly recommends that you leave the AQ_TM_PROCESSES parameter unspecified and let the system autotune.

Note:

If you want to disable the Queue Monitor Coordinator, then you must set AQ_TM_PROCESSES to 0 in your parameter file. Oracle strongly recommends that you do NOT set AQ_TM_PROCESSES to 0. If you are using Oracle Streams, then setting this parameter to zero (which Oracle Database respects no matter what) can cause serious problems.
