Before you can manage a repository with a PowerCenter Repository Service, you need a database to hold the repository database tables. You can create the repository on any supported database system.
Use the database management system client to create the database. The repository database name must be unique. If you create a repository in a database with an existing repository, the create operation fails. You must delete the existing repository in the target database before creating the new repository.
To protect the repository and improve performance, do not create the repository on an overloaded machine. The machine running the repository database system must have a network connection to the node that runs the PowerCenter Repository Service.
You can optimize repository performance on IBM DB2 EEE databases when you store a PowerCenter repository in a single-node tablespace. When setting up an IBM DB2 EEE database, the database administrator must define the database on a single node.
