The following table describes the database requirement for the TDM repository:

After you install TDM, verify that the Informatica domain contains the repositories required to use TDM. If the domain does not contain a PowerCenter repository, you must create the repository in the Informatica domain. You must set up the database for the repository before you create the PowerCenter Repository Service.

If you have the Data Discovery option, you must create a Model repository and profiling warehouse in the Informatica domain. You must set up the databases before you create the Model Repository Service and Data Integration Service.

The following table describes the requirements for the repository databases:

Informatica Component	Database Type	Disk Space	Comments
PowerCenter repository	IBM DB2 UDB Microsoft SQL Server Oracle Sybase ASE	35 MB	Set up the database before you create the PowerCenter Repository Service. Allocate more space based on the number of repository objects you plan to store.
Model repository	IBM DB2 UDB Microsoft SQL Server Oracle	200 MB	Set up the database before you create the Model Repository Service. Allocate more space based on the number of repository objects you plan to store.
Profiling warehouse	IBM DB2 UDB Microsoft SQL Server Oracle	35 MB	Set up the database before you create the Data Integration Service.
