Comments on: Saving Rows from Corrupt Blocks http://kerryosborne.oracle-guy.com/2009/02/saving-rows-from-corrupt-blocks/ Just another Oracle blog Thu, 29 Jul 2010 12:17:10 +0000 http://wordpress.org/?v=2.6.3 By: osborne http://kerryosborne.oracle-guy.com/2009/02/saving-rows-from-corrupt-blocks/#comment-306 osborne Fri, 13 Mar 2009 21:44:20 +0000 http://kerryosborne.oracle-guy.com/?p=922#comment-306 Toon, Nice to meet you too. I enjoyed the first half of your talk this year (I skipped the second half to listen to someone else - that I can't remember now). Anyway, you had me nodding my head up and down on the whole talk. I think moving the majority of code towards the database and away from the application is absolutely the way to go. Your paper on working around block corruption was very helpful on this particular situation. While it wasn't actually block corruption (which we have other mechanism to solve now), the approach worked great. We had a billion+ row table. Fortunately it was partitioned and we were able to export by partition - only a couple of sub-partitions had the problem - so those we ran through block by block, row by row. Got it all back but 2 blocks - about 100 records I think (out of 1.3 billion or so). Not bad! Thanks for writing that paper! Kerry Toon,

Nice meeting you at Hotsos. Toon Kerry, I was pleasantly suprised to hear that a paper written over 15 years ago, still helped out someone. Nice meeting you at Hotsos.
