This script is called by the Master
Control Script and acts as an interface
between the Master Control Script and
Toolkit Module Script
(tkit_module.sh)
the toolkit interface script
(hadg.sh/hadg_rac.sh). It is also
responsible for calling the toolkit
Configuration File Generator Script
(described below).
This script is called by the Module
Script when the package configuration
Toolkit Configuration File
Generator Script
(tkit_gen.sh)
is applied using cmapplyconf to
generate the user configuration file
(hadg.conf) in the package directory
(TKIT_DIR).
This script is called by the Master
Control Script and acts as an interface
External_pre Module Script
(cc_ext.sh)
between the Master Control Script and
the External_pre interface script
(hadg_rac_cc.sh). This external script
is used in Continentalclusters
environment.
The following parameters must be provided in the Package Configuration File
Table 5 Package attributes
DescriptionVariable Name
This parameter determines whether Active Data Guard
must be enabled on a Physical standby database instance
ACTIVE_STANDBY
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. To enable this feature, you can set the toolkit 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, you must not set
the toolkit parameter to [yes] without a license.
The ODG Broker is a distributed management framework
that automates the creation, maintenance, and monitoring
MONITOR_DG_BROKER
of Data Guard configurations. The parameter
MONITOR_DG_BROKER specifies whether the ODG broker
can 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: If broker configuration is enabled when this
parameter is set to [no], the toolkit fails the package startup
to avoid issues. Therefore, this must be avoided.
This is an ODG feature that enables log apply services to
apply redo data as it is received, without waiting for the
REAL_TIME_APPLY
current standby redo 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].
