Open Source Database Clusters?

grugruto asks: "A lot of open source solutions are available to scale web sites with clusters but what about databases? I can't afford an Oracle RAC license but can I have something more reliable and fault tolerant than my single Postgres box? I have seen this recent article that looks promising for open source solutions. Do anyone have experiences with clusters of MySQL , Postgres-R, C-JDBC or other solutions? How does it compare to commercial products?"

Bailing wire and duct tape

Clusters? Usually, we just tape a bunch of cats together...

Damn, I thought is was barbed wire. No wonder I was the only one having a hard time.

Am I offtopic? I thought this was a farming thread. :)

The hay (rolls and bales) came with that cheap fiberous twine (grass of some sort), but ours wasn't red. Different parts of the world, I suppose.

Some places used the plastic strapping, but that wasn't very popular with the farmers.

I've seen twine, plastic strapping, steel strapping, and metal wire, depending on what the application is.

I find, when shorting out equipment, baling wire works best. Just loop it across every bare soldier joint you can find, and apply power. Twine just doesn't have the same effect.

Insulated wire is good if you're running a lead from the ignition coil to someone's seat. ZZzzap! Ahh, the good ol' days, when you could play a practical joke without being called a terrorist.

"Hey Bob, catch this capacitor!"

**OUCH!!**

WhooHoo!

"Hey Bob, touch this wire, tell me if it's live."

{{ZZAP}}

"Hey Bob, try this Windows machine out, tell me if it crashes."

Doh.

Silly Bob, he'll never learn.

Is it just me or is that last sentance rather hard to parse?

Huh?

You can "cluster" MySQL? Does it involve "rsync" and "cron"?

Re:Clustered JDBC

[Anonymous Coward]

You mean C-JDBC, as linked in the story text? Wow, nice sleuthing to find that one.

is it just me?

[gfody]

or does this term sound kind've like a made up buzzword like ".NET powered Java schemas!" or "SOAP servlet toaster oven with X-M-L!"

I get the feeling that in a room with more than one door, it takes you all day to find your way out. :)

Java's turn...

Here's another experience I love.

I'm in mozilla, and I middle click a link. Somewhere in the background a page starts loading in a new tab. No problem. I will continue reading. Ah, background loading into new tabs.

Then.

The.machine.comes.to.a.halt.

It.takes.me.awhile.to.realize.this.

but.

I.can.not.scroll.I.can.do.nothing.

And I know what's happened. Some moron has a java applet displaying something wonderfully important like the fucking time in their little corner of hell, and if I wait about thirty more seconds, I'm going to hear a little pop, and I just know the sound of that pop is like the sound of a dick popping out of my anus, cause I know that java has just ass raped me, my browser, and my machine.

Pop! Your clock is now ready sir!

O U C H ! ! ! ! Rapist.

I mean VMS has only advanced two major versions in ten years.

Yeah... then all the maintainers went off and started Debian.
