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
Oracle
Sybase ASE
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.
