]]> Comment on Standby database creation of VLDBs by Jay Stanley, Sr. Staff Consultant http://www.dbspecialists.com/blog/database-backups/standby-database-creation-of-vldbs/comment-page-1/#comment-5270 Jay Stanley, Sr. Staff Consultant Fri, 11 Nov 2011 00:13:58 +0000 http://www.dbspecialists.com/blog/?p=220#comment-5270 That's a good question. The main disadvantage to using RMAN to just do incremental block recovery, is that it's bulk-based; it won't keep the standby database in-sync as close-in-time to just applying archived (or online in the case of dataguard) redo relatively constantly. The place where I've see it most useful is when you have a very large database that takes many hours/days to back up. You can do 1 backup (with the block change tracking file active), then just do incremental updates to that backup. So, it's more of a backup solution than a standby solution per-se. -jay That’s a good question.

Regards, Good.
