Chapter 16
This chapter exists for the purpose of steering you in the right direction in

Possible approach:
First, check the system errorlog (or event log on NT). Usually there will be an

Have you examined all operating system logs?
Are you signed in as the sybase user or an OS system admin? (A common
mistake; you should be signed in as the sybase user to start the server.)
Is the server already started?
Are the environment variables set up correctly? On Solaris, if a file such
as SYBASE.csh is not sourced, the environment variables are not set up
and the server may not start.
Have the file or partition permissions changed?
