RAC - UNDOTBS

edited Apr 25, 2013 4:48AM in Database - RAC/Scalability (MOSC) 4 commentsAnswered
Hi,
Kindly let me know the usage of undotbs per instance in RAC database.

My understandings are :
1. All instances can read the undotbs of other instances.
2. Undo block written by a instance cannot be modified by other instance.

Thanks,
Sriram

Howdy, Stranger!
