Re: Keeping December partition through the year

Nice people of the EMC corporation will gladly help you out. As we, the DBA folks, like to say, disks are cheap. The last increase in the storage capacity that my company bought in February didn't cost me a penny. It was all paid for by the company. So, as a DBA to DBA, I recommend you to adopt relaxed and aloof attitude toward disks and storage ASAP. Burn as much storage as you can. You can even ask EMC for kickbacks. Set all your datafiles to autoxtend, without specifying the maxsize. A 32GB temporary tablespace will be able to hold all of your sorts from the invention of the wheel till present, and simultaneously. Set undo retention to 24 hours to honor Kiefer Sutherland. That way, we may be able to save some precious storage at freelists.org.
