I know with the Diva Distro version of OpenSim that I installed on my XP 64-bit partition, you had to use a different .exe to launch it. Ironically I think it was OpenSim.32BitLaunch.exe

I think the issue has to do with the implementation of the physics engine, but I'm not sure. At any rate, it's certainly possible to run OpenSim in Windows XP 64-bit, presumably the same applies to Vista and 7 as well.

I haven't tried running it on Linux yet. I haven't used my OpenSim setup in a while anyways.

Just to add to the above posts, my machine is 64 bit and yes it works fine as long as you launch with OpenSim.32BitLaunch.exe instead of opensim.exe

mysql stores your assets, both the ones that are provided in the Library and that you subsequently create. What role apache plays in the standalone is beyond me.

Masami Kuramoto

I think Apache and PHP were added for MySQL administration (e.g. through phpMyAdmin). They certainly are not required for OpenSim itself.

In fact OpenSim doesn't even require MySQL. For standalone installations like this, the built-in SQLite database would be sufficient -- and much easier to handle as well.

Han Held

Opensim defaults to using sqllite to store your assets [both library and imported] if you don't specify it to use mysql.

There's a few reasons I'm going on about this, I'm not just being contrarian:

1)I was recommended by someone who appeared to be a regular in osgrid that if you're just using opensim in a standalone, that mysql isn't necessary.

2)Mysql is a fucker to set up, even for someone like myself whose got a decent knowlege of computers

3)Running mysql opens up one more port on your computer, which imo is a bad thing if it can be avoided. Needless to say, that goes double for for apache.

4)If you are able to just unpack an opensim zip onto a usb stick and run it as-is w/out configuring two additional servers that would make it easier for people, and may even make it more accessible in places where people can't get permissions to run servers [eg university computers].

All I can say is that I run local opensim installs on my hard disk w/out mysql or apache. It may be that I'm doing something wrong and not knowing it (and if I am, I'd like to know what and why it's wrong). It's entirely possible I'm overlooking something...
Ok, and that's what I'm overlooking in my tl;dr post [hey, I literally woke up 5 mins before writing my post, I haven't had coffee yet]...I don't use the phpMyAdmin panel. I simply go in and work from the console, but I imagine most people these days would feel more comfortable with a web interface than a console one.
Thanks.

No, I didn't build this -- all I had to do was upload it!



You can download the archive file here:
Condensation Land club

Adding it to your OpenSim:
1. Download and unzip the .oar file
2. Drop CondensationLandClub.oar in the opensim/diva/bin folder
3. Fire up your opensim and log in
4. In Opensim.exe command window at Region <root> # prompt, type: load oar CondensationLandClub.oar
5. Watch the new build rez!

Warning, this replaces the current Region 1 sim, so tidy up before adding it.

Hey, anyone have a strongly recommended turnkey OS installation that is more than standalone?

For those who have long suspected, yep I sure do have an OS grid of my own but but am now thinking it's finally time to open it up to outsiders.



Also, regarding mega regions, anyone have a setup where pulling in the oar file actually distributes and updates *all* regions, rather than just a single region in one corner?

SilenzZzz

very interested in this .. is there a way to tweak the number of sims? and prim limit for each one? ... like to add some ones around the 4 main that would mostly be water and such?

By the way, the latest releases of the Diva distribution (based on OpenSim 0.7.x) come with a web interface that handles account management. Visitors can use it to create accounts, choose between several default avatars, and retrieve their passwords via email.

This is extremely useful if you want to make your standalone OpenSim accessible to the public. In previous versions of OpenSim, additional accounts (and their passwords) had to be set up manually by the administrator.

As I've said in previous threads, I think the future of OpenSim is distributed, not centralized. Sandboxes will be run at home, while high-demand sims will be run 24/7 by commercial server hosting providers. And everything will be loosely connected via hypergrid. If a node fails, the rest of the grid won't be affected.

You can add (or remove) sims via simple console commands. No need to shut down the server for that. If you do it while logged in, you'll literally see the new sims pop up next to you.

You can also load and save regions to files and move them between grids. It's ideal for backups, making snapshots etc.

OpenSim has no hardcoded prim limit as far as I know.

SilenzZzz

ahhh okay thanks. and once you create the new sims (say on the stick install) does it keep them? or do they have to be recreated every time? ...

already got the stick up and running ... makes building and testing stuff out much easier ... but having some ideas for a potential 'cloud' hosted one as well .. wanting to try it out first on a stick to decide.

Masami Kuramoto

Yes.

Desmond Shang

Hypergrid will definitely be the way forward for public OS, but I suspect that hypergridded or not, some region clusters will still be more equal than others. If only by virtue of who is running them, and how much we trust those people with our data.

* * * * *

I'd been looking at Diva but just simply hadn't got round to it. Best out there nowadays? I thought Adam had a turnkey setup at one point too... Maybe I should set aside a couple hours and see how Diva works out.

A big issue for me has been the inherent backup/restore functionality, because I've figured that any content I've done with OS might possibly bounce around from one test grid to another several times before it settles down.

And that's just my stuff ~ once anyone else's data gets into the mix it's a *completely* different can of worms. Frankly I dread the issues of anyone else uploading stuff ~ suddenly I get to wonder if it's 100% legitimate or not. And if I'm ever hacked, even once, even for a second ~ what would I tell people. There are scripts out there that are worth a small fortune.

And it's one thing to have a hobby OS install on a spare computer, with a crappy low bandwidth residential connexion. And a whole different thing to have six sigma quality uptime and backups. Even with leasing from a cloud. I have to wonder who works at a lot of these server farms ~ do we all just interently trust those folks? Google employees have been fired for egregious privacy violations. I can't imagine many server farm employees that haven't heard of SL and would also be aware of the value of say, Stroker's products for instance.

Besides all that, the tech issue that's got me, is that right now restored oar files don't distribute across their source regions correctly for megaregion setups (unless that's changed?) ~ which is a problem.

* * * * *

At the bottom of all opensim issues, I think, is... trust. Anyone who can accomplish trust in the opensim environment has the best chance there, over the very long run.

Masami Kuramoto

The cool thing about hypergrid 1.5 is that you don't have to log into anyone else's grid any more. You can log into your own standalone OpenSim instead and then teleport over. This means that your inventory is stored on your local machine, and anything that is not in the "My Suitcase" folder will be invisible to the other grids. Your local asset server will deny any remote transfer requests by default. You won't be able to rez or wear things on any foreign grid unless they are in the suitcase folder.

So the only OpenSim installation you have to trust is the one you run on your own computer.

I haven't tried the Diva distro yet but will do so as soon as it supports mesh. In the meantime I'll just compile the current development version from source, which is a matter of entering three console commands.

Chouchou, who recently lost their SL regions, seem very interested to try OpenSim as a machinima filming set and eventually as an on-demand concert venue. They already streamed their recent concerts and radio shows from SL to ustream.tv and nicovideo.jp, and this is something they could do just fine from OpenSim as well. I'm going to help them set up an OpenSim sandbox in the Amazon cloud in the next few weeks, so we'll see how that works out.

Need a walk cycle? I love Mixamo! Some neat walks there, make sure you use the SL character to test them out!

After struggling -- and failing -- to get Tateru Nino's pre-packaged OS setup working on both home and work computers, I erased everything and started from scratch.

This time I skipped the "user-friendly" approach that included a MoWeS component (running Apache, PHP and SQL) and simply installed the latest OpenSim directly to my USB thumb drive. I like this installation process MUCH better because I was able to set up a Region name and Beebo Brink as my region owner at the beginning, instead of having to make those changes afterwards. This ensures that any assets created or loaded to my new Brazen World realm are automatically created and owned by Beebo, rather than Test User.

The other issue I had was extreme lag with the 4-sim version. Despite the heady joy of allll that land, I'm running much faster with the single sim option.

And finally, it works with both my home computer and my work computer. Whatever issue was blocking the Apache server on my work computer is now a moot point.

Version 0.7.0.2: Download - OpenSim

Beebo Brink

After installing the latest version of the OS stand-alone, I started browsing the various builds that can be uploaded within just a few minutes.

OpensimWorlds

Loading Archive files:
1. Drop the OAR file in your OpenSim bin folder
2. Fire up your opensim and TPV
3. Type in the command window: Load OAR filename.oar
4. Watch a new world unfold.

Warning: unless you use merge in the command, this will completely replace Region 1. If you have a two or 4 sim setup, I recommend reserving Region 1 for OAR uploads.

Merging Archive files with region:
load oar --merge filename.oar

OAR builds I've uploaded this week:

Yesterday I installed OpenSim on a virtual machine running Ubuntu Server 10.04. My goal was to simulate the entire setup procedure the way it would occur on a remote dedicated server at Amazon or elsewhere. So I made a bare-bones install of Ubuntu and then went through the following steps using only a secure shell and the command line tools available on the server:

• installing MySQL and creating a user/schema pair for OpenSim,
• installing Mono and Git,
• downloading, compiling and configuring OpenSim,
• registering OpenSim as a service to be launched automatically during system startup.

Now all I need to do is rent a server and replicate these steps.

By the way, I compared Amazon's prices with those of a popular hosting provider in Germany (Hetzner), and now I'm not so sure if Amazon's implementation of cloud computing is an attractive solution. It's nice to pay only for the resources actually used, but if I decide to keep the sim running 24/7, Hetzner's product is much cheaper, despite the current EUR/USD exchange rate.

Sometimes the CLI is the way to go.

What's a shame is that people seem to be scared enough of the CLI that they'll jump through a ton of unneeded hoops just to have that web consoley thing even tho it in the end simply gets in the way [at least from what you're saying about having to change from Test User to Beebo Brinks].

Set up everything but the client in a VM so you have a uniform environment?

As noted in posts today, I scrapped the MoWeS application that relied on Apache, PHP and SQL. Something in Apache kept hanging for my work computer. But the direct installation of OpenSim on the USB works just fine. Now I can easily carry my sim work with me wherever I go: home, work, on trips.

I suspect I need a better thumb drive, though. I can't find any confirmation that my current USB is 2.0 (where would I get that info?). And I can always be talked into buying another one, so this time I'll look for a high performance drive in the $20-25 range. If that makes any difference in performance (especially the arduously long save/shutdown process) it will be worth it.

Argent Stonecutter

Can you make that VM available as an appliance in OVF?

Argent Stonecutter

Unless it's 5 years old, it's "USB 2.0". The problem is that a couple of companies with a big inventory of USB 1.1 chipsets got the USB standards body to redefine USB 1.1 as "USB 2.0 full speed". What was previously USB 2.0 became "USB 2.0 high speed". So you need to look at the device properties and make sure it says that.

I was going to give you a description of how to do that, but they "upgraded" me to Windows bloody 7 here, and I'm discovering that I can't find that specific information any bloody where.

DanielRavenNest

Device Manager > USB Controllers
Open each item looking on the power tab to identify ones that have something plugged into the controller
Then go to Advanced tab to find Hub speed
High Speed = USB 2.0
