The ODG toolkit can be implemented as a combinational package with the ECMT Oracle toolkit.
A combinational package has two applications packed together by combining their respective
Serviceguard modules into one package.
The ODG toolkit depends on the ECMT Oracle toolkit. Hence, customers who do not already have
the ECMT product must purchase it along with the ODG toolkit.
As a combinational package, the Oracle database will be brought up first using the ECMT Oracle
toolkit. The Data Guard processes will then be started by the ODG toolkit, after which, the
application is monitored.
Since the Oracle database and the Data Guard are packed together, the package will failover if
either the Oracle database or any of the Data Guard processes fail. Note that since the primary
database and all the standby databases are configured in separate clusters, separate combinational
packages must be created for each primary and standby database.
Configuring an ODG toolkit involves two scenarios:
1. If a customer already has an ECMT Oracle toolkit package running and wants to convert the
Oracle database into a Data Guard setup, then:
• If the ECMT Oracle package is a legacy-style package, then it must be halted and
discarded and new package needs to be created using both ECMT Oracle toolkit module
and ODG toolkit module. This is because the ODG toolkit does not support Legacy
packaging.
• If the ECMT Oracle package is a modular-style package, then halt the package first and
then insert Data Guard module using the following command:
cmmakepkg –i <pkg_ascii_file> -m <module_file_name>
<output_file_name>
