10.5 About the Simplified Refresh
From Base Option
The Simplified Refresh From
Base option is similar to the Refresh Base option. It allows you to upgrade from a DAC Repository from an older release of
Oracle BI Applications to a new release, but you cannot compare
repositories and create a
Difference Report.
If you want to upgrade a DAC
Repository from an older release of Oracle BI Applications
to a new release and you want to compare repositories and create a Difference Report before merging the repositories, you must use the
Refresh Base option. See "About the Refresh Base
Option" for more information.
Before you begin this procedure, do the following:
■ Determine what customizations were made to your existing
DAC Repository.
■ Make sure you have renamed and backed up your existing
DAC Repository into a
different database. When you
backup the DAC Repository, you export the DAC metadata, in
XML format (using the DAC's Export tool), into a folder other than the standard DAC export folder where backups are stored (DAC\export).
For instructions on exporting DAC metadata,
see "Exporting DAC Metadata".
To upgrade the DAC metadata
repository
1. Upgrade your existing
DAC Repository tables to be compatible with the new DAC Repository release.
a. Configure the new DAC
client version to read the DAC metadata from your existing DAC
Repository.
b. Log in to the DAC and
select Yes if prompted to upgrade the repository tables.
2. Export the custom
applications from your existing custom repository to a folder
other than the standard DAC
export folder (DAC\export) or the folder into which you backed up metadata in the previous format.
3. Import the new DAC
metadata for your application from the standard DAC export folder (DAC\export). Select the Truncate Repository Tables check
box. For instructions on importing DAC metadata,
see "Importing DAC Metadata".
4. Import the customized
DAC metadata that you exported in Step 2, and deselect the Truncate Repository Tables check box. This will
append all the custom data to the repository, thus bringing in the customizations, which include the following:
■ All modified data.
■ All newly created custom data.
■ All deleted data.
5. Refresh the source
system container to locate any missing objects in your customized application. The missing objects are any new objects that the preconfigured applications may have that are not referenced in the
custom applications.
a. Navigate to the
Upgrade/Merge Wizard by selecting Tools, then DAC Repository
Management, and then Upgrade/Merge Wizard.
b. From the drop-down
list, select Simplified Refresh From Base, and then click OK.
c. Select the
appropriate container from the Source System Container drop-down list, and click OK.
d. Confirm that you want
to refresh the source system container.
6. Rebuild all the
subject areas and execution plans in your customized application to include any new changes in the object dependency. For information about building subject areas and execution plans, see "Customizing
DAC Objects and Designing Subject
Areas" and "Building, Running and Monitoring Execution Plans".
