You said it - 16MB is badly underconfigured for the task. If you add things up you will find your UNIX kernel + system processes will take at least 8MB, and the ORACLE instance including its shared memeory area (the SGA) will take a minimum of 8MB too. So you have no memory to work in, the system spends all its time swapping, and your users start getting mad !

I use 32MB RAM on my system, and its still not enough. I believe 64MB is more reasonable. In these days of relatively cheap RAM, it is crazy to cripple your system for the sake of a thousand dollars.

Another point though - unless its absolutely necessary, its not a good idea to mix development and production environments on the same system.

If you want proof of the system swapping, you can use 'sar' or get a copy of 'svr4mon'.
