RMAN Merged Incremental Backup Ignores SECTION SIZE

(Doc ID 2402594.1)

Last updated on MAY 23, 2018

Applies to:

Oracle Database - Enterprise Edition - Version 12.1.0.2 and later
Information in this document applies to any platform.

Symptoms

Customer is running the following RMAN backup script, as shown here.

backup section size 2G incremental level 1 for recover of copy datafilecopy format '/oradata/oracle/indx/%b' with tag 'img_copy'
datafile
156,190,259,260;
backup section size 2G incremental level 1 for recover of copy datafilecopy
format '/oradata/oracle/data/%b' with tag 'img_copy' datafile
1,
...

However, RMAN ignores the SECTION SIZE clause and thus does not backup the datafiles in parallel.

Changes

 No changes, wanting to parallelize the datafile copy taken by RMAN's merged incremental backup strategy.
