One work around might be to create a dedicated Oracle account with the suitable rights (INSERT on the table to load) and to use a login trigger to assign the rollback segment. Another, and probably much better, way would be to have several sessions running and parallel (and hopefully assign to different rollback segments by Oracle). If your volume of data is really big, chances are that you are loading into a partitioned table. If your input data had the good taste of being made of several files, each one destined to a separate partition, would be great. Perhaps some preprocessing is required. Otherwise split your data file, be certain to have several free lists to avoid contention, and there you go. You may have to play with constraints, this is usually the price to pay to do things in parallel. -- Regards, Stephane Faroult Oriole Software -- Please see the official ORACLE-L FAQ: http://www.orafaq.net -- Author: Stephane Faroult 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).
