What is \oracle\ECD\sapdata1\undo_1\UNDO.DATA1
On our development server drive one of the file UNDO.DATA1 occupied more than 10 GB disk space, the path for the file is \oracle\ECD\sapdata1\undo_1\UNDO.DATA1.
Can anybody explain me what is the use of this file & if I delete the file then it cause any inconsistency or not.
Do not play with UNDO.DATA1 coz it can cause inconsistency in your system
it is just like undo segment in oracle... do a google search for more about undo segment.
