Which Blocks Will RMAN Check For Corruption Or Include In A Backupset? (Doc ID 561010.1)

Last updated on AUGUST 04, 2018

Applies to:

Oracle Database - Enterprise Edition - Version 8.0.3.0 to 11.1.0.6 [Release 8.0.3 to 11.1]
Oracle Database - Enterprise Edition - Version 8.0.6.0 to 11.1.0.7 [Release 8.0.6 to 11.1]
Information in this document applies to any platform.

Goal

The goal of this document is to explain which blocks a RMAN checks for corruption, the difference in which blocks are checked when the "validate" clause is used with a RMAN backup, and which blocks are placed into RMAN backupsets.

Background:  A RMAN backup causes RMAN to read blocks into memory, write these blocks to another part of memory, check these blocks for corruption during the memory to memory write, then write these blocks to the output device (tape or disk).  If the "validate" clause is used with a RMAN backup, the same process occurs but RMAN does NOT write the block to the output device.
