The installation program sets the error log location in the Sybase installation directory when you configure a new Adaptive Server. Backup Server and Monitor Server each have their own error logs.
The default location for each server’s error log is:
Adaptive Server: $SYBASE/$SYBASE_ASE/install/error.log
Backup Server: $SYBASE/$SYBASE_ASE/install/backup.log
Monitor Server: $SYBASE/$SYBASE/install/ms.log
At start-up, you can reset the name and location of the Adaptive Server error log file from the command line. Use the -e start-up parameter and value in the dataservercommand to start Adaptive Server.
Multiple Adaptive Servers cannot share the same error log. If you install multiple Adaptive Servers, specify a unique error log file name for each server.
