Copy the “run_server” file and name it with a “m_” prefix to indicate single user mode; for example, m_RUN_servername.
Edit the m_RUN_servername file to add the single-user mode flag (-m on Unix) in the dataserver command.
At a Sybase install directory prompt, enter:
startserver -f m_RUN_servername
