Re: native Oracle-port on Linux -- what would it take?

: Linux is missing many features for any OS to be worth considering
: as a viable database platform.

this author is uninformed.

: 1. Linux has no logical volumes layer.

MD exists, though it's very close to a full LVM.

: 2. Linux has no transaction-oriented filesystem.

thank god! now, please explain how you want a FS to be ACID, and why this is relevant to a database.

: 3. Linux has no support for raw devices - hence NO even remote possibility
: to run Oracle Parallel Server.

DB people are acolytes of a black religion. one of their main items of faith is that you must have raw devices. as such, there's no reason to ask for a defense of this item. besides, didn't you want an ACID FS, rather than raw devices? also, ever heard of O_SYNC?

: 4. Linux networking is flaky at best.

BULLSHIT. let me guess, you're a *BSD dweeb, right?

: 5. Linux OS block size is what? 512 bytes? It would make even MS Access
: laugh and puke steam.

no, asshole.

: 6. Linux SMP is rudimentary and flaky at best.

no, asshole.

: 7. The same for multithreading.

no, asshole.

: 8. Oracle requires efficient IPC and record-locking mechanisms. Linux
: cannot do
: record-locking at all, last time I checked. So Oracle would have to
: write its own
: code for that. Why would anyone sane want that?

actually, most serious transaction and DB systems _do_ definitely want to do their own locking.

: Cordially,

yeah whatever.

summary: Linux is free and extremely fast/efficient on dirt-cheap hardware. it's consciously aimed at _workstation_ performance, but a single competent programmer could turn it into an excellent server platform in a month or two. Received on Thu Dec 18 1997 - 00:00:00 CST
