Integration server HTTP listener parameters (SOAP and HTTP nodes)

Select the resources and properties that are associated with the HTTPInput, HTTPReply, SOAPInput, SOAPReply, and SOAPAsyncResponse nodes that you want to change.

To change these properties, you must specify the broker name and -e followed by the name of a single integration server, and -o to specify the integration server object. If you specify -o ExecutionGroup, you can omit -e to change a property that applies to all integration servers on the specified broker.

Because you define all of these properties at the integration server level, they apply to all HTTPInput, HTTPReply, SOAPInput, SOAPReply, and SOAPAsyncResponse nodes that you deploy to the specified integration server.

By default, the HTTP nodes that you deploy to the broker all use the single broker-wide listener. If you prefer, you can change the configuration of the broker so that all integration servers use the embedded listeners in the integration servers. You can also use the broker-wide listener for some integration servers, and the embedded listener in other integration servers. For more information about these options, see HTTP listeners.

By default, the SOAP nodes that you deploy to an integration server all use the embedded listener. You can change the configuration of some or all of your integration servers so that they use the broker-wide listener. For more information about these options, see HTTP listeners.

If you want HTTP or SOAP nodes to use the broker-wide listener, see Broker-wide HTTP listener parameters formore information about setting this configuration.

You must restart the integration server for all changes to be implemented.

Choose the ObjectName from the following options:

ExecutionGroup for controlling common properties
HTTPConnector for controlling HTTP communication.
HTTPSConnector for controlling HTTPS communication.

The following combinations are valid:

-o ExecutionGroup

The following properties and values are valid:

-n httpNodesUseEmbeddedListener

Set the value to false, to make all HTTPInput and HTTPReply nodes use the broker-wide HTTP listener, if this listener is enabled. Set the value to true to make all HTTPInput and HTTPReply nodes that are deployed to the specified integration server use the embedded integration server listener.

If you disabled the broker-wide HTTP listener, all HTTPInput and HTTPReply nodes use the embedded listener regardless of the value of this property.

Value type - Boolean
Initial value - false

-n soapNodesUseEmbeddedListener

Set the value to true to make all SOAPInput, SOAPReply, and SOAPAsyncResponse nodes use the embedded HTTP listener. Set the value to false to make all SOAPInput SOAPReply, and SOAPAsyncResponse nodes that are deployed to the specified integration server use the broker-wide listener, if this listener is enabled.

If you disabled the broker-wide HTTP listener, all SOAPInput, SOAPReply, and SOAPAsyncResponse nodes use the embedded listener, regardless of the value of this property.

Value type - Boolean
Initial value - true

-o HTTPConnector

The following properties and values are valid for HTTPConnector and HTTPSConnector:

-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
Initial value - 2097152 (2 megabytes)

-n acceptCount

Set the value to the maximum number of incoming connection requests that can be queued. Requests that are received when this limit is reached are rejected.

Value type - integer
Initial value - 100

-n compressableMimeTypes

Set the value to a list of MIME types that are applicable for HTTP compression. Other MIME types are not compressed.

Value type - comma-separated list
Initial value - text/html,text/xml,text/plain

-n compression

Set the value to off to disable compression, on to compress text data, force to compress all data, or the minimum size (in bytes) of data that must be received, before the output is compressed. If compression is enabled and the content-length is not known, all the output is compressed.

Value type - string
Initial value - off
Note: For the webadmin component, compression is turned on by default for new brokers.

-n connectionLinger

Set the value to the number of seconds for which the sockets (used by the HTTPConnector) must remain active after a shutdown is initiated.

Value type - integer
Initial value - JVM default

-n connectionTimeout

Set the value to the number of milliseconds the HTTPConnector must wait for a request to be received after it accepts a connection. Set the value to -1 to specify no timeout.

Value type - integer
Initial value - 60000

-n maxHttpHeaderSize

Set the value to the maximum size (in bytes) that the HTTPListener accepts for an HTTP header.

Value type - integer
Initial value - 8192 (8 kilobytes)

-n maxKeepAliveRequests

Set the value to the maximum number of requests that can use a persistent connection. Set the value to 1 to disable keep-alive requests and force the creation of a new connection for each request. Set the value to 0 or -1 to allow unlimited requests.

Value type - integer
Initial value - 100

-n maxThreads

Set the value to the maximum number of threads that can be created by the HTTPConnector.

Value type - integer
Initial value - 200

-n minSpareThreads

Set the value to the minimum number of threads that must be active.

Value type - integer
Initial value - 10

-n noCompressionUserAgents

Set the value to a regular expression that, when matched with the user-agent header, disables compression.

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
Initial value - null

-n serverName

Set the value that is set in the "Server" header for all HTTP responses sent by this server.

Value type - string
Initial value - Apache-Coyote/1.1

-n socketBuffer

Set the value to the size (in bytes) of the buffer that must be used for socket output buffering. Set the value to -1 to disable the use of a buffer.

Value type - integer
Initial value - 9000 (9 kilobytes)

-n tcpNoDelay

Set the value to true, to send small packets immediately.

Value type - Boolean
Initial value - true

-n enableLookups

Set the value to true to use DNS lookups to return the host name of the remote client. Set the value to false to return the IP address instead.

Value type - Boolean
Initial value - false

-n explicitlySetPortNumber

Set the value to the TCP/IP port number on which the Connector creates a server socket and awaits incoming connections.

Setting this value disconnects the automatic port-finding capability of the connector; this port is the only one allowed, and the connector fails to start if another program has already used this port.

Value type - integer
Initial value - 7800-7842
Other valid values - any integer in the range 0-65536.

You must use the explicitlySetPortNumber attribute, because the port attribute no longer works.

When you set the value to zero, the system enables the automatic port-finding capability again, starting with the last used port, which was saved by the integration server. You can change the default port that is used when port-scanning starts by explicitly setting a value in the range 7800-7842, then specifying the port number as zero.

The initial value for HTTPS is 7843 within the range 7843-7884.

-n autoRespondHTTPHEADRequests

Use this value to specify if the connector handles HEAD requests for HTTP traffic in the same way that it does for SOAP traffic. Set the value to true to make the connector return an HTTP 200 OK response if the request is for a URI associated with a message flow.

Set the value to false to invoke the message flow if the request is for a URI associated with a message flow. The flow receives the request like a new message, and must be able to handle a HEAD request for proper handling.

Note: If the request is not for a URI associated with a message flow, the connector returns an HTTP 404 Not Found response.

Value type - boolean
Initial value - false

-n integratedWindowsAuthentication

Set the value to NTLM to use the NTLM protocol (Windows only), Negotiate to use the Negotiate process (SPNEGO) to select between NTLM (on Windows) and Kerberos protocols, or Negotiate:Kerberos to negotiate only the use of the Kerberos protocol. Multiple values can be specified, separated by a semicolon or a space, and are not case-sensitive. The order that the values are specified in, is the order in which they are returned to the client in the HTTP response. To disable Integrated Windows Authentication, set this property to a blank string.

Value type - string
Initial value - null

-o HTTPSConnector

The properties that are listed for the HTTPConnector are also valid for the HTTPSConnector. The following additional properties and values are valid for the HTTPSConnector:

The following additional properties and values are valid:
