Jared, What would you be looking for in the DDLs for old and new tables? I can post them here, but the are very very long and I don't think anyone will have time to look over them thank you Gene Gurevich "Jared Still" <jkstill@xxxxxxxx m> To nigel_cl_thomas@xxxxxxxxx 01/17/2008 07:42 cc AM genegurevich@xxxxxxxxxxxx, oracle-l <oracle-l@xxxxxxxxxxxxx> Subject Re: SQL*Loader performance On Jan 16, 2008 2:52 PM, Nigel Thomas <nigel_cl_thomas@xxxxxxxxx> wrote: That's all I can think of at this time of night... All I can think of is this: Without knowing the exact structure of the old table, and seeing the DDL for the new tables, as well as any procedures that may have changed, any attempt at diagnosis is just a guess. By procedure I mean something like 'We drop index i1 and i2 when we load the table", which would beg the question "Is there now an index i3?" -- Jared Still Certifiable Oracle DBA and Part Time Perl Evangelist -- //www.freelists.org/webpage/oracle-l
