Ports needed for Web Services with WebSphere Message Broker

Technote (FAQ)


Question

You are using WebSphere Message Broker and need to plan for HTTP and HTTPS traffic supporting either standard HTTP calls or SOAP HTTP messaging. You need to know how many ports will be used and how to configure which ports are in use.

Answer

In Message Broker version 6.1 and later, each instance of a single Broker can use several different ports for different HTTP based functions.

By default the following set of ports will be used if the corresponding function is activated in Broker. All of these port numbers are completely user-configurable. This table lists the defaults:

Port# Usage
7080 This port will be used by the bipHTTPListener process for plain HTTP traffic to all ExecutionGroups
7083 This port will be used by the bipHTTPListener for encrypted HTTP (HTTPS) traffic to all ExecutionGroups
7800-7842 This range of ports will be assigned incrementally for plain HTTP traffic to each EG that has a SOAPInput node, in the order that each EG starts up
7843-7885 This range of ports will be assigned correspondingly to the plain HTTP traffic port for HTTPS traffic to each EG that has a SOAPInput node, in the order that each EG starts up

To give a clearer example of how the above works, suppose you have a single Broker with two ExecutionGroups, each with an HTTPInput node and a SOAPInput node. If both the HTTPListener and the SOAP HTTPConnector are configured to allow both plain and encrypted HTTP (http and https), then the following ports will be used:

7080 - all unencrypted traffic to all HTTPInput nodes in both ExecutionGroups
7083 - all encrypted traffic to all HTTPInput nodes in both ExecutionGroups
7800 - all unencrypted traffic for SOAPInput nodes deployed to the first ExecutionGroup that starts up
7801 - all unencrypted traffic for SOAPInput nodes deployed to the second ExecutionGroup that starts up
7843 - all encrypted traffic for SOAPInput nodes deployed to the first ExecutionGroup that starts up
7844 - all encrypted traffic for SOAPInput nodes deployed to the second ExecutionGroup that starts up

In order to assist you in managing this complexity and present a simpler picture to your webservice consumer applications, Message Broker comes with an HTTP Proxy Servlet that can be deployed to any of a large number of free and commercial Java Enterprise Edition containers. Documentation on the HTTP Proxy Servlet in version 7 starts here.

In addition, in Broker version 7.0.0.1, this picture is simplified. In 7.0.0.1 and later of Broker, the HTTP nodes can use the SOAP Listener rather than the bipHTTPListener process. There is an overview of this including links to further discussion here.

The ports used for the bipHTTPListener can be configured individually on each Broker by using the options for mqsichangeproperties as described here, with corresponding information on configuring the ports for SOAPInput over HTTP and HTTPS here.

It is also possible to assign a fixed and static port number for SOAPInput for a specific EG, rather than having the port being determined by the order in which your EGs start up. This is also done using the mqsichangeproperties command.

The necessary steps to enable and configure SSL for HTTP and SOAP are documented here and here, respectively.
