Connections between the Web Connector and WCS, or between the application tier and CMS
Not all Crystal Enterprise components use the directory listing service on the CMS to make their initial connections with other elements of Crystal Enterprise.
The Web Connector (WC) contacts the Web Component Server (WCS) using a pre-defined address and port number. The WCS replies to the WC with its address and a second port number, which by default is selected dynamically. This address and second port number is used for all subsequent communications between the two components.
Communications between the WCS and CMS (or a Crystal SDK and the CMS) follows the same pattern as WC - WCS communications. The WCS contacts the CMS using a pre-defined address and port number. The CMS replies with its address and a second port number, which by default is selected dynamically. Subsequent communications continue using this address and second port number.
You can use the -requestport command to configure the WCS or CMS to reply with a fixed port number for subsequent communications, rather than one that is dynamically selected. Using the -port option, you can also customize the WCS or the CMS to listen on a specific port for initial communications, rather than using the pre-defined default values (port 6401 for the WCS, and port 6400 for the CMS).
Note:
- Before changing the default port numbers, see Changing the default server port numbers for additional configuration information.
- You may also change the default port that the CMS or WCS uses to listen for initial communications from the Configuration tab of the Properties dialog in the Crystal Configuration Manager.
