In our application we have est. 350 Tables with a range of rows between 10 and 10.000.000. Because of this and the fact that some of our customers use Oracle 7.3.4 we decided to split the different tables across 3 different tablespaces with fixed extent sizes. It is very good described in the white paper from Oracle about fragmentation. Here is the Link: http://metalink.oracle.com/cgi-bin/cr/getfile_cr.cgi?239049 We decided to think about 1 year in the future for every table. One reason was the ability of Oracle 8.1.7 to move tables to another tablespace. The customers with Ora7 are forced to change the release to ORA8i. So we don´t need to expect the rowcount for 5 years, because of the fact, that new Oracle Releases often have new abilities dealing with such problems. One example is of this fact is Ora8i and the local managed tablespaces. It´s worth to think about a solution with one ore more tablespaces with this feature enabled. We have very good experiences with this. > Any Idea appreciate. > Thanks, > > Hamid Alavi > hth Jörg Jost -- ----------------------------------------------------------------- Software Engineering Vattmannstraße 7, 33100 Paderborn Phone: (+49) 52 51 / 30 1 6333 Fax: (+49) 52 51 / 30 16 399 eMail: [EMAIL PROTECTED] http://www.unitrade.com ------------------------------------------------------------------ -- Please see the official ORACLE-L FAQ: http://www.orafaq.net -- Author: Joerg Jost INET: [EMAIL PROTECTED] Fat City Network Services -- 858-538-5051 http://www.fatcity.com San Diego, California -- Mailing list and web hosting services --------------------------------------------------------------------- To REMOVE yourself from this mailing list, send an E-Mail message to: [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and in the message BODY, include a line containing: UNSUB ORACLE-L (or the name of mailing list you want to be removed from).
