Can I Use Multiple Metadata Repositories?

Installing OracleAS Infrastructure

If you are interested in seeing the names of all the schemas, see the Oracle Application 
Server Metadata Repository Creation Assistant User’s Guide.

You can install multiple metadata repositories to increase performance. This enables 
different components in your topology to use different metadata repositories. To use 
multiple metadata repositories, follow these guidelines:

■

To enable a Portal and Wireless or a Business Intelligence and Forms middle tier to 
use a second metadata repository for product metadata:

Install the second metadata repository and register it with the Oracle Internet 
Directory.

You can do this using the installer or the OracleAS RepCA. Use the installer to 
create a new database containing the OracleAS Metadata Repository, or use 
the OracleAS RepCA to install the OracleAS Metadata Repository in an 
existing database. See the Oracle Application Server Metadata Repository Creation 
Assistant User’s Guide for details.

When you install the Portal and Wireless or the Business Intelligence and 
Forms middle tier, select the second metadata repository from the list of 
registered repositories. This is the metadata repository that the middle tier will 
use for its product metadata.

■

To use a second metadata repository for a J2EE and Web Cache middle tier, you 
have different options, depending on which J2EE and Web Cache features you 
need:

■

If you need both the Oracle Identity Management Access feature and the 
Database-Based Farm feature, you need to register the second metadata 
repository with the Oracle Internet Directory.

■

If you need only the Database-Based Farm feature, you do not need to register 
the second metadata repository. The reason for this is that you might not have 
an Oracle Internet Directory.

 shows a topology that involves two metadata repositories. It uses four 

computers:

■

Computer 1 runs a metadata repository and Oracle Identity Management 
components. The Oracle Identity Management components use this metadata 
repository.

■

Computer 2 has a metadata repository that is registered with the Oracle Internet 
Directory running on Computer 1.

■

Computer 3 has a Portal and Wireless middle tier. This middle tier knows to use 
the metadata repository on Computer 1 for its product metadata because it was 
registered with that metadata repository during installation.

■

Computer 4 also has a Portal and Wireless middle tier. This middle tier knows to 
use the metadata repository on Computer 2 for its product metadata because it 
was registered with that metadata repository during installation.
