If several SQL statements were executed, you can access the results and the messages
relating to these SQL statements with a drop-down list.
Web Server
The Web Server is the client part of the SAP DB Web tools Web DBM [Page 154] and Web
SQL [Page 154]. The server for the Web DBM tool is the DBM Server [Page 58], the server
for the Web SQL tool is the database instance [Page
132].
Possible Web servers are the SAP DB Web Server or the well-known Web server Apache.
The SAP DB Web server is installed during the installation of the SAP DB Web tools. Apache
must be installed separately or configured. For more information, see the Installation Guide
Web Tools: SAP DB 7.4 [See SAP DB Library].
Web DBM and Web SQL are operating-system-independent. These tools are installed once,
and can then be called from any browser. This enables occasional users as well as frequent
users to make use of the Database Manager and SQL Studio functionalities quickly and easily
in the network.

X Server
The X server (Remote SQL Server) is the communication instance of the SAP DB software
when the individual components are located on different computers.
• Database applications and servers of the SAP DB tools (for example, Loader) address
the X server when they want to establish a connection with a database instance installed
on another computer.
• Clients of the SAP DB tools (for example, Loader) address the X server when they want
to establish a connection with a SAP DB tool server (for example, DBM Server, Loader)
installed on a different computer.
Each time a connection is successfully established, an additional X server instance is started
(Windows: Thread, UNIX: Process). This X server instance is needed to transport the data
packages across the network. When the connection ends, the X server instance is closed.
