I use it, works great, 60% savings. Once the table/partition gets flagged "compress", any direct load will be compressed. You will get ora-600 if trying to do parallel direct load. Also can't add a column to a compressed table. Waleed -----Original Message----- From: LeRoy Kemnitz [mailto:lkemnitz@xxxxxxxx] Sent: Friday, March 19, 2004 3:41 PM To: Oracle List Subject: Table compression I am looking into doing some table compression on my warehouse database to free up some space on the os. I am running 9.2.0.4 on Unix 5.1. The compression is about 2.5:1 on my tables. The documentation says the bulk insert time will be doubled but the single inserts, updates, and deletes are going to be a wash. Does anyone use compression? Are there any problems you notice in the use of it? I have also read that the table will need to be re-compressed after the bulk inserts. Any alternative ideas about getting this done?
