Speed up datapump export for migrating big databases

By | Database Administration & Monitoring, Database management, Hardware & Storage, Oracle | One Comment

Introduction Big Oracle databases (several TB) are still tough to migrate to another version on a new server. For most of them, you’ll probably use RMAN restore or Data Guard, but datapump is always a cleaner way to migrate.

But datapump export can…

Documentum – MigrationUtil – 2 – Change Docbase Name

By | Application integration & Middleware, Entreprise content management | No Comments

You are attending the second episode of the MigrationUtil series, today we will change the Docbase Name. If you missed the first one, you can find it here.
