Darren a 1 : === I would use both thprof to make sure that the SQL is efficient and statpack to monitor the full database a 2 : === I would never recommend to make the data files bigger than 2 Gb on unix, so anything up to 2 GB will be fine. How small you what to make the files depends on the number of disk's or if you use raid to strip ?
a 3 : === You would use locally managed table spaces and make the extend size 1, 4, 10 or 512 Mb in this case it does not matter. a 4 : === Yes, if the table space is read only you only need one backup but on the other hand who gives a dam on 4 - 6 GB tape per today Browett, Darren wrote: >We are in the process of installing a GIS package (Arc/info) which has an >oracle component (SDE) > >I have to setup tablespaces to handle various types of data, one of the >tablespaces will be holding >Tiff images.
