DG_BROKER_START

Property	Description
Parameter type	Boolean
Default value	`false`
Modifiable	`ALTER SYSTEM`
Range of values	`true \| false`
Basic	No

DG_BROKER_START enables Oracle to determine whether the Oracle Data Guard broker (DMON) process should be started. DMON is a non-fatal Oracle background process and exists as long as the instance exists, whenever this parameter is set to true.

If the site is never going to be configured in an Oracle Data Guard broker configuration, then you can leave the parameter unspecified and accept the default value of false. If the site is part of an Oracle Data Guard broker configuration, then automatic startup of the DMON process is simplified by setting DG_BROKER_START to true in the initialization parameter file.
