If you are running Sametime 8.5 either on Windows or on Linux you need to create some script to start all components automatically on server startup. Michael Urspringer has already done this for Windows and Enio Basso contributed a script for Linux.
In addition, Sasa Brkic recently posted a script to start the DB2 server on Linux.
I have also written such a script earlier this year that has some additional options.
You can either start stop or restart the whole Sametime 8.5 server or only selected components. And you can get the status of for example the meeting server by typing
./sametime status meeting
at the shell console.
