Before building a repository domain, verify that you have the following required elements:
A licensed copy of Informatica to create the global repository.
A license for each local repository you want to create.
A database created and configured for each repository.
A PowerCenter Repository Service created and configured to manage each repository.
A PowerCenter Repository Service accesses the repository faster if the PowerCenter Repository Service process runs on the machine where the repository database resides.
Network connections between the PowerCenter Repository Services and PowerCenter Integration Services.
Compatible repository code pages.
To register a local repository, the code page of the global repository must be a subset of each local repository code page in the repository domain. To copy objects from the local repository to the global repository, the code pages of the local and global repository must be compatible.
