Home -> Community -> Mailing Lists -> Oracle-L -> RE: Altering Indexes
Dennis:
Thanks for the advice. Fortunately I am doing a DB conversion from IMS / Lotus Notes to 8.1.7. This is being done on a dedicated server which only I have access to and there is no application software connected to it. When I finish the data conversion the data will be exported (for want of a better word) to the production DB where it will be tested. So, taking time do "something" is not a problem. Currently the only data I have on the system is a small lookup table. So, the process would probably go rather quickly.

Ken - No, there isn't a magic single command. Moving the indexes, even with
alter index, cause a lot of work for Oracle, and can consume quite a bit of
time. As the typical cautious production DBA, I do not like to start a
really large monolithic process that might make my system unavailable to the
users for an unknown period of time. I would recommend that you use SQL to
create a script to alter the indexes. This will allow you to Pareto's rule
to do the many small indexes first, then work up to the larger indexes that
use increasing amounts of time. Also, I would recommend considering several
index tablespaces, maybe even moving the largest tables to their own
tablespace first.

I have this large DB (approx. 250 tables) that has the tables and indexes in the same tablespace (not my design). Is there a way I can move all of the indexes to a separate tablespace en-mass? I know I can move them one at a time with the alter index command, but that would be rather time consuming.
Thanks,
