Table 4 Module scripts of the HP Serviceguard toolkit for Oracle Data Guard
File Name | Description | Available in Directory |
Toolkit Module Script | This script is called by the Master | /etc/cmcluster/scripts/tkit/ |
(tkit_module.sh) | Control Script and acts as an interface | dataguard |
| between the Master Control Script and |
|
| the toolkit interface script |
|

The following parameters must be provided in the Package Configuration File Table 5 Package attributes
Variable Name | Description |
ACTIVE_STANDBY | This parameter determines whether Active Data Guard |
| must 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 |
| 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. |
MONITOR_DG_BROKER | 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 |
| 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. |
REAL_TIME_APPLY | This is an ODG feature that enables log apply services to |
| apply redo data as it is received, without waiting for the |
| 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]. |
