To change these properties, you must specify the broker name and -b httplistener.
The httplistener component defines properties for the broker that are used for all the HTTP and SOAP input and reply nodes that are configured to use the broker-wide listener.
You must restart the broker for all changes to be implemented.
The following combinations are valid for the httplistener component:
-o HTTPListener
The following properties and values are valid:- -n enableSSLConnector
- Set the value to true to make the HTTP listener
listen for inbound SSL connections.
- Value type - Boolean
- Initial value - false
- -n startListener
- Set the value to true to make all HTTP nodes
in all integration servers use the broker-wide listener (unless you
activated the embedded listener in an integration server by using
the mqsichangeproperties command
for that integration server). For information about configuring an
integration server so that HTTP nodes can use the embedded listener,
see Integration server HTTP listener parameters (SOAP and HTTP nodes).
SOAP nodes use the embedded listener by default, but can be configured to use the broker-wide listener by using the mqsichangeproperties command. See Switching from a broker-wide listener to embedded listeners.
Set this value to false to make all HTTP nodes use the listener that is embedded within each integration server.
- Value type - Boolean
- Initial value -true
-o HTTPConnector
The following properties and values are valid:- -n address
- If your server has more than one IP address, set the value to the IP address that is used for listening on port 7080. If this property is not set, port 7080 is used on all IP addresses associated with the server. A maximum of one address can be specified.
- Value type - string
- Initial value - null
- -n maxPostSize
- Set the value to the maximum POST size (in bytes) that can be processed by the broker-wide listener. Set the value to 0 to remove the limit.
- Value type - integer

- Value type - string
- Initial value - null
- -n restrictedUserAgents
- Set the value to a regular expression that, when matched with the user-agent header, disables keep-alive.

- Value type - string

- Set the value to true, to send small packets immediately.
- Value type - Boolean

- Value type - Boolean
- Initial value - false
- -n accessLog
- Set the value to true to enable access valve logging. When it is enabled, access valve logging generates a web server access log in the $MQSI_WORKPATH/components/<Integration_node_name>/httplistener directory. The log provides details of all accesses to the URIs that are served by the broker-wide HTTP listener.
You can customize the format of entries in the web server access log by using the accessLogPattern property.
- Value type - Boolean
- Initial value - false
- -n accessLogPattern
Set the value to customize the format of entries in the access log that is enabled by the accessLog property. Ensure that the value is in the same format as the format described in the
Apache Tomcat 7 documentation.The following header, which provides performance measurement information about the time that a request has spent waiting in the broker-wide HTTP listener, is also supported:%{X-IIB-Timing}o- Value type - string

Tip: The valid values for keystoreType, sslProtocol, and ciphers are JSSE-implementation-specific. These values are in the JSSE provider documentation. For a list of the platforms that use IBM® Java™, see Appendix A of the IBM JSSE2 Guide, at: http://www.ibm.com/support/knowledgecenter/SSYKE2_6.0.0/com.ibm.java.security.component.60.doc/security-component/jsse2Docs/ibmjsse2.html.
