I think 9202 doesn't like to export compressed tables in direct mode ... so watch out for that ... I implemented, tested and next day reverted back to regular tables due to this export issue. Disk is cheap.

"Compress to impress?" by Julian Dyke is a good presentation on this topic (see for instance http://www.ukoug.org/calendar/jan03/jan30ab.htm).

I do have the article - 202 K with no compression, 147 K with compression :).

Let me know if you're interested, and I'll email it directly to you.

>Does anybody has any experience with Oracle 9I compression option. I did
some test on 9202 with a table of more 14 million rows. Table has total 7 indexes. Surprising both table and indexes are using more space after compression. Before compression space used is 13064MB and after compression 13184MB. In both the cases I did export from source table and stored in two different tablespaces. Any insight on that and any disadvantages of using that.
