Displaying Communications Process and Listener Information

You can see the information held in the repository for communications processes and listeners by clicking Details on the Home page in the Communications Process column for the enterprise server instance that you are interested in. The communications process and listener table is shown below.

Figure 1. Communications Processes and Service Listeners Table

The information for a communications process is as follows:

Auto-start - whether or not the communications process is started automatically when the enterprise server instance starts.
Listeners - the number of listeners owned by this communications process.
Process ID - the process ID of this communications process. This is present only when the communications process is running.
Control Channel Address - this is an internal address used by enterprise server instance components for communications. An asterisk at the end of the IP address or port number indicates that this part of the address is not fixed but supplied by the host system on startup.
Status information - you can see the current status and the time of the last status change.
Status log - this supplies information about the most recent event that occurred for this communications process.
Version - this is the version number of the communications process software.

Communications processes do not have names; instead they have sequence numbers. The communications process that is automatically created when you add a new enterprise server instance is Communications Process 1, and any further communications processes that you create are numbered in ascending order of creation. When you delete a communications process, existing communications processes are not renumbered, however, the next communications process you create will use the same number as the process that was deleted - the lowest available number.

The information for a listener is as follows:

Name
Address - this is the network address on which the listener listens for incoming client requests. An asterisk at the end of the IP address or port number indicates that this part of the address is not fixed but supplied by the communications process on startup.
Status information - you can see the current status and the time of the last status change
Status Log - this supplies information about the most recent event that occurred for this listener
