here is the section responsible for the Servlet configuration, as shown in the following
code:
<httpconfig>
...
<webappconfig>
...
<servletconfig>
...
<servlet-list>
<servlet> ... </servlet>
...
</servlet-list>
</servletconfig>
</webappconfig>
...
<plsql> ... </plsql>
</httpconfig>
The Servlet configuration section is a child of the protocol configuration described as fol-
lows:
<protocolconfig>
<common> ... </common>
<ftpconfig> ... </ftpconfig>
<httpconfig> ... </httpconfig>
</protocolconfig>
From this section, you can clearly see that two protocols are supported by default: FTP
protocol and HTTP protocol. Actually, one more is also supported, a WebDAV. Standard
Local Listener is responsible for the handling of all XDB requests according to the para-
meters registered in the configuration sections as shown earlier, <ftp-port> and
<http-port> . In addition, it is essential to add the related dispatcher entry to the
init.ora file: dispatchers="(PROTOCOL=TCP) (SERVICE=<sid>XDB)" .
You can always check the currently configured XDB Listener ports executing under the
DBA privileges:
select dbms_xdb.gethttpport(), dbms_xdb.getftpport() from
dual;
