- Very. As root, use cpio (or possibly tar) to extract product off
- distribution media into directory where product will live --
- /usr/informix is the normal place. Then run the install script
- (./installsql, ./installstar, or whatever) to brand the product.
- End of installation.
-
- If you are commissioning OnLine and want to use raw disks (a good
- idea), then you need to know how to set up a raw partition which
- is not being used by Unix. This can be tricky to do
- retrospectively -- but it is a problem with Unix rather than
- Informix per se.

- It depends on the engine. Standard Engine is not very tunable --
- it is simple to install and largely idiot-proof. OnLine is
- considerably more complex and does benefit from tuning, though
- even untuned configurations work, often surprisingly well
- considering... More important, in general, is tuning the database
- design, and the way the application uses the database. As many
- performance problems are due to poor application design as they
- are to engine performance.

-
- Of course they do. I don't have shareable code, I'm afraid. Are
- you sure you want to do TPC-A on a 486? The difficulty with TPC-A
- is the terminal handling rather than the database handling.
