Starting X Server 
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.
Procedure
x_server [<options>] [start]
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. More information: Ports and Protocols of X Server |
-V |
Displays the version of X Server. |
-w |
On Unix and Linux, only in SAP systems Restricts the command to the SAP NISSL connection |
-W |
On Unix and Linux, only in SAP systems Suppresses automatic use of SAP NISSL |
-y |
On Unix and Linux, only in SAP systems Restricts the command to the SAP NI connection |
-Y |
On Unix and Linux, only in SAP systems Suppresses automatic use of SAP NI and SSL |
-Z <file_size> |
Specifies the size of the xserver_<computer_name>.prt log file in KB. <computer_name> is the name of the computer on which X Server is running. More information: Database Administration, Log Files |
