Analysis Services (SQL Server 2000)Migrating Analysis Services Repositories

Migrating Analysis Services Repositories

  New Information - SQL Server 2000 SP3.

For each Analysis server, Microsoft® SQL Server™ 2000 Analysis Services creates a repository called the Analysis Services repository to store meta data for the objects of the Analysis server (cubes, dimensions, and so on). By default, this repository is a Microsoft Access (.mdb) database on the server computer where Analysis Services is installed. By default, this database is:C:\Program Files\Microsoft Analysis Services\Bin\msmdrep.mdb

If the SQL Server 2000 database engine is available to the Analysis server, either on the same computer or another computer, you can migrate the Access repository to SQL Server. Doing so adds the enterprise-level scalability, support, and security of the SQL Server database engine for the Analysis Services repository. If the SQL Server 2000 database engine is not already installed on your network, and you are supporting enterprise-level applications for Analysis Services, you may consider a minimal installation of SQL Server 2000 to support the SQL Server 2000 repository for Analysis Services.You can use the Migrate Repository Wizard to migrate the Microsoft Access repository to a SQL Server (.mdf) database on the same or another server computer. You can also use the wizard to migrate a SQL Server repository to another SQL Server database.Important  After you migrate the repository to a SQL Server database, you cannot migrate the repository back to a Microsoft Access database. For added security, you should remove the Access database after you successfully complete the migration.You can change the format of your repository when you migrate it from the default Microsoft Access database to a SQL Server database or from one SQL Server database to another SQL Server database. By default the repository is in SQL Server 7.0 OLAP Services format (Analysis Services native format). You can keep this format when you migrate the repository or you can change the format to use the SQL Server 2000 Meta Data Services repository format.Analysis Services native format is recommended. If you choose to migrate the repository to a SQL Server database (native or Meta Data Services), it is recommended that you create a dedicated SQL Server database for the repository instead of using an existing database (such as msdb). Before you start the Migrate Repository Wizard, create or identify the SQL Server database to which you want to migrate the Analysis Services repository.To start the Migrate Repository WizardAnalysis ManagerAnalysis Manager [ http://msdn2.microsoft.com/en-us/library/aa198116(SQL.80).aspx ] After migration, both the old and new databases remain; however, only the new database is used by Analysis Services. You can manually delete the old database by deleting the file in Windows Explorer. If an error prevents the Migrate Repository Wizard from finishing successfully, the migration is canceled, and Analysis Services continues to use the repository it used before you started the wizard.

How to start the Migrate Repository WizardTo start the Migrate Repository Wizard

1. In the Analysis Manager tree pane, expand the Analysis Servers folder.

2. Right-click the server whose Analysis Services repository you want to migrate, and then click Migrate Repository.
