Parameter type	Integer
Default value	`1`
Modifiable	`ALTER SYSTEM`
Modifiable in a PDB	Yes
Range of values	`0` to `40`
Basic	No

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 statement.

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.
