Why? Because I've been working in IT for fairly large companies for quite a few years now and the opportunities for practice and creativity are directly proportional to your herd instinct and inversely proportional to your actual ideas. Hmmm...that sounded bitter--my favorited kind of chocolate.
The Oracle DBMS is a bottomless pit of configurability, connectivity, programmability, and buzzword-ability. I want an opportunity to set up ASM, GRID, OEM, Tranparent Encryption, and a host of other things that require multiple hosts, disks, and some root access. My answer is to buy 2 CHEAP smaller Linux based computers with 2 internal hard disks, and 2 ethernet ports per host.
My intention will be to journal the adventure here. I've already received the computers from a company that specializes in pre-loaded Linux servers. I think it was a good buy. I'll put up some pictures of he computers and info about the company next.
The systems are preloaded with Ubuntu Linux, which has become quite popular. I could not care less. I look for the core, vanilla Unix parts of these *nix distributions and try to live there. That Linux has a volume manager VERY similar to that used on HP-UX is gravy for me. I've booted one of them and done a little configuration. I set the bios setting to ignore the lack of a keyboard being attached. The little thing can now run "headless"; that is, without a keyboard, mouse, or display monitor. I've configured it to run sshd as a service, so I attach to it with ssh/scp/sftp from another computer, such as my laptop. I can then "throw" myself various X Windows client items, such as xterms, firefox browers and, the Oracle Universal Installer (OUI). This is just like working with the big, expensive data center housed Unix servers in IT, at a fraction of the cost.
It's good to be SA and DBA and owner. I AM the change management department.
