Note Note

On Microsoft Windows, the SAP MaxDB installation program registers X Server as service XServer, sets the Startup Type for this service to Automatic and starts the service. You do not have to start it manually.

On Unix and Linux, X Server is not automatically installed as a service. You can either enter X Server in the appropriate startup scripts for your operating system or start it manually when required. After startup, X Server runs in the background as process vserver. When starting X Server, a special process for supporting the SAP NI network protocol is started.

End of the note.

Procedure

x_server [<options>] [start]

Starting X Server: Options

Option

Description

-D <debugging_level>

You can specify values from 0 (no debugging information is written) to 9 (maximum debugging information). The default value is 0.

-F

If you set this option, X Server does not determine the computer name of the application logging on to the DNS server (no reverse DNS lookup).

If it is taking a long time to connect to a remote database, restart X Server with this option. This way you will find out whether the DNS server is responsible for the slow connection.

-S <port>

On Unix and Linux only: assigns a different <port> to X Server. X Server uses port 7210 by default.
