Home -> Community -> Mailing Lists -> Oracle-L -> RE: Execution time for export/import vs. alter table move tablesp
Just listened to a talk by Kevin Loney (noted Oracle author). Table-table
data movement (alter table move) is the fastest way to move data in Oracle.
How much faster depends on your system. My experience says twice as fast is
a safe guess. Cost justifying an upgrade?? What ogres do you work for?

tablespace command
I am doing a cost justification for upgrading a data warehouse from 8.0.4 to 8.1.7.
I need to submit it today and don't have time to do a test on a very large table.
Does anyone have anecdotal evidence or experience in the time difference required to reorg a tablespace using the export/import table method versus alter table move to a new tablespace method?
Thanks for any time quotes you can provide. I'm especially interested in very large tables and tablespaces.
Thanks,
