Re: "Memory issues" on HPUX

Solaris' kernel parameters are a lot simpler that HP's. Practically all of Solaris' parameters are dynamic, whereas on HP, you need to do a fair bit of tweaking.

A good example is the need to allocate memory available to Oracle, so you can size the SGA accordingly. Chances are, you will need several goes at it before arriving at an optimal configuration.

With demand paging on Solaris, the kernel shuffles resources (especially memory) around as required.

Once the parameters are set, installation and db creation goes along quite smoothly.

However, this advise goes for any platform (HP, IBM, Sun, NT, Linux).
