Before you create a repository, you need a database to store repository tables. Use the database client to create the database. After you create a database, you can use the Administrator tool to create a Model Repository Service.
Each Model repository must meet the following requirements:
Each Model repository must have its own schema. Two Model repositories or the Model repository and the domain configuration database cannot share the same schema.
Each Model repository must have a unique schema name.
In addition, each Model repository must meet database-specific requirements.
The Model Repository Service uses the DataDirect drivers included with the Informatica installation. Informatica does not support the use of any other database driver.
Mappings will fail with the following error if the database schema for the Model Repository Service database is not DB2:
[runmapping] failed with error [ [JSF_0045] The requested interface [com.informatica.ds.ms.common.MappingService]
is not available.]
