ZDLRA, Dataguard, Archivelogs, and RMAN-08137

When configuring a database with Real-Time Redo at ZDLRA it is important to check the deletion policy for archivelog. This is even more important when the database is protected with dataguard. I already wrote about Real-time Redo in this previous post, and when using with dataguard in another post.  

But sometimes (during maintenance as an example) you can face the error RMAN-08137: warning: archived log not deleted, needed for standby or upstream capture process if the deletion policy of archivelog is not aligned with your needs.

ZDLRA, Virtual Private Catalog User – VPC

Leave a reply

The Virtual Private Catalog (VPC) user is a key piece for a good ZDLRA architecture design. The detail is not how to create it, but how to correctly integrate it in your design, and this is more important if you have replicated ZDLRA or using Real-Time redo transport.

Here I will show and discuss VPC implications for your architecture design when deploying ZDLRA. Even for a complete and new implementation (together with database) or adding ZDLRA at your already running environment. All points here try to show some perspectives and key points that can help you to correct use and define VPC’s.
