back out an alter table modify column

edited Feb 8, 2017 9:42AM in Database Administration (MOSC) 7 commentsAnswered ✓

We have to increase a column from number(4) to number(9) on 5 large (> 20G tables).  What if some corruption occurs during the modify and we have to back off the change.  An export of these tables before the change will take too long.  Any suggestions?

It's RDBMS EE 11.2.0.4; ASM running on HPUX.

Howdy, Stranger!
