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. With datapump, you can easily migrate to a new filesystem (ASM for example), rethink your tablespace organization, reorganize all the segments, exclude unneeded components, etc. All of these tasks in one operation. But datapump export can…

Focus on 19c NOW!

By | Database Administration & Monitoring, Database management, Oracle | 2 Comments

Introduction For years, Oracle used the same mechanism for database versioning. A major version, represented by the first number.

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. I did this change on Documentum CS 16.4 with Oracle database, on the same docbase I already used to change the docbase ID. My goal is to do both changes on the same docbase because that’s what I will need in the future.
