Suppresses startup error windows.
iqsrv16 -qs ...
Windows
This option suppresses startup error windows. Examples of startup errors include the database server not being able to open or read a database file or a database server not starting because another database server with the specified name is already running.
On Windows platforms, if the server isn't being started automatically, these errors appear in a window and must be cleared before the server stops. These windows do not appear if the -qs option is used.
If there is an error loading the language DLL, no window appears if -qs was specified on the command line and not in @data. This error isn't logged to the -o or -oe logs, but rather to the Windows Application Event Log
Usage errors are suppressed if -qs is on the command line, but not in @data expansion.
