Property Description
Parameter type Boolean
Default value false
Range of values true | false
Basic No

DG_BROKER_START enables Oracle to determine whether or not the 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 a Data Guard broker configuration, then you can leave the parameter unspecified and accept the default value of false. If the site is part of a 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.
