A PowerCenter repository is a collection of database tables containing metadata. A PowerCenter Repository Service manages the repository and performs all metadata transactions between the repository database and repository clients.
The PowerCenter repository supports the following database types:
IBM DB2 UDB
Microsoft SQL Server
Microsoft Azure SQL Database
To install the PowerCenter Repository Service with the 10.4.0 installer, you can use the Oracle, Microsoft SQL Server, or the PostgreSQL database. If you want to install the PowerCenter Repository Service on any of the other databases, you create the service with the required database after you run the installer.
Allow 35 MB of disk space for the database.
Ensure that you install the database client on the machine on which you want to run the PowerCenter Repository Service.
For more information about configuring the database, see the documentation for your database system.
