Hello.~
I want to use Oracle database in SGS. If I can,… How?
Is there Load balancing system in SGS?
I know that SGS is distributed system. But I couldn’t test it.
Can I use 2 computers(two servers) for distirbuted system ?
Could you let me know about that ?
What should I do?
Thanks.
ps. Sorry for my poor English skill.
If all you want to do is query an oracle database you can do it right now through the Raw Socket ,manager but you need to code the potocol to connect yourself.
We are currentrly discussing better ways to do this in the “Eve liek game” topic.
If you want to store your GLOs in an Oracle database, evetually we ar talkign about maybe opening an interface layer but currently that is not open.
Yes, the whole point behind the system is that it allows you to scale up and load balance your game automatically.
The SDK is purposefulyl limtied to a single system. This is ebcause the SDK is not for commercial distribution, it is only for applciation development. So it obviosuyl does nto do multi-system laod-balancing.
The production system, what we call the “big backend”, will do that for you. But as its all automatic there is no difference in your code. You write your code using the SDK and then deploy it to the “big backend” when you reach the stage where your game needs to be scaling tested.
Is there any test-server or other mechanism for potential users to see that in action?
The Playground is coming soon, we hope to have it live by JavaOne.
The Playground is going to be a hosted Darkstar backend run by Sun for Darkstar developers to use to alpha and beta test their software on the internet. As those developers get their content up and running it will be possible for end users to see the full SGS in action.
Also, with the move to Open Source you will eventually be able to get your hands on a muti-node stack if you want to run it yourself. Be warned though that the multi-node stack may require a serious data center back end to perform properly. (eg It may well require 10 gig ether or inifiniband switches between the nodes.)

By the way, with 0.9 the way you access external systems has changed.
Rather then going through the Raw Socket manager (which no longer exists) you write a custom service or manager that installs right into the stack itself.
I’m working on the docs on this right now with my deadline being JavaOne.

can we do this in 0.9.0 now Jeff dude?
No, not yet but RSN. We are hoping to have the 0.9 multinode released for JavaOne. Thats a hope not a promise, but we’re working hard at it right now.
Keep in mind my warning though… running a multi-node system will require more then just two boxes. Its a pretty complicated configuration where the master Object Store moves off onto its own cluster. And without well performing boxes and a lightening fast inter-connect you are likely to see the “stereo system” effect. Which is to say any stereo system is only as good as its weakest component and the same is likely to be true here as well.
Just out of curiosity, what are the specs on the PDS playground, what/how many CPU’s per box, how many boxes, OS, RAM, interconnect, DB etc etc, all the gory details :). It makes no real difference to me, but I’m interested

What I could give you now would only be approximate guesses as Gary, hardware wizard extraordinaire, is building it out now and to some degree the final specs will be driven by actual tests and measurements. (Crazy, I know, but at labs we like to do things a bit differently 
)
What I can tell you is that we haven’t ruled out options like all infiniband and IB switches for interconnects if it makes a significant difference…
i have an Macintosh LC II and a ZX-86, will that be ok? or we talking Sun Fire / XServs- or even having to Blading it up (swoosh swoosh im a jedi night)?
