DRS_START

Parameter type	Boolean
Default value	false
Parameter class	Dynamic: ALTER SYSTEM
Range of values	true | false

DRS_START enables Oracle to determine whether or not the DRMON (Disaster Recovery Monitor) process should be started. DRMON is a non-fatal Oracle background process and exists as long as the instance exists.

If the site is never going to be configured in a disaster recovery configuration, you can leave the parameter unspecified and accept the default value of false. If the site is part of a disaster recovery configuration, automatic startup of the DRMON process is simplified by specifying DRS_START = true in the initialization parameter file.
