DescriptionVariable Name
This parameter determines whether Active Data Guard has to be enabled on
a Physical standby database instance or not. The Active Data Guard Option
available with Oracle Database 11g Enterprise Edition enables the physical
standby database to be opened for read-only access. This feature can be
enabled using the toolkit by setting it to "yes" in a package for Physical
Standby database. The default value is “no.”
NOTE: To enable Active Data Guard, the user needs an optional license
from Oracle. Therefore, this toolkit parameter should not be set to "yes" without
the license.
ACTIVE_STANDBY
The ODG Broker is a distributed management framework that automates the
creation, maintenance, and monitoring of Data Guard configurations. The
parameter MONITOR_DG_BROKER" Specifies whether the ODG broker is to
be used or not. It can take values “yes” or “no.” The default value is “no.”
This parameter can be used in RAC environment only. Data Guard Broker is
not supported in the toolkit in Single Instance database environment.
NOTE: Broker configuration should not be enabled when this parameter is
set to “no”. If enabled, the toolkit fails the package startup to avoid issues.
MONITOR_DG_BROKER
Real Time Apply" is an ODG feature that enables log apply services to apply
redo data as it is received, without waiting for the current standby red log file
to be archived. This results in faster switch over and failover times. To enable
this feature with the toolkit set the toolkit parameter "REAL_TIME_APPLY" to
"yes" in the package configuration file. The default value is "no".
