| Parameter type | Boolean |
| Default value | false |
| Modifiable | ALTER SYSTEM |
| 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.
