Simple Standalone Sim Startup Script

Instructions

This script assumes that you will start the sim whenever you are using it.

The sim will run as a job in its own terminal.

To shutdown the sim you enter the SHUTDOWN command at the terminal prompt.

Script

#! /bin/sh
cd /home/opensim/diva-r11766/bin
export MONO_THREADS_PER_CPU=125
mono OpenSim.exe

Grid Mode /etc/init.d script for Linux

Instructions

Tested on Debian 5. CHUIDS user to opensim user. Supports: start, stop, restart, status

To implement: Type: cat > /etc/init.d/opensim Paste in script from this page Press: CTRL+D Type: chmod +x /etc/init.d/opensim Script should now be located on server and be executable.

Type: update-rc.d opensim defaults Script should now be in your startup.

Modify header in script to adapt it to your installation folder and user.

NOTE: stop-command currently doesn't work properly (it doesn't do a soft shutdown). It will kill OpenSim first with kill pid, then kill -9 pid. So make sure you have saved your data. :)
