| Range of values | 0 to 40 | 
| 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.
The default value for AQ_TM_PROCESSES is used if the client does not explicitly set a value for the parameter in the init.ora file or using the ALTER SYSTEM command.
Note:
If you want to disable the Queue Monitor Coordinator, then you must setAQ_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.See Also:
