Settings for the SOAP Inbound Adapter

Provides reference information for settings of the SOAP inbound adapter, EnsLib.SOAP.InboundAdapter. Also see “Creating a Web Service in a Production,” which does not require this adapter.

Summary

The inbound SOAP adapter has the following settings:

The remaining settings are common to all business services. For information, see “Settings for All Business Services” in Configuring Productions.

Adapter URL

A specific URL for the service to accept requests on. For SOAP services invoked through the SOAP inbound adapter on a custom local port, this setting allows a custom URL to be used instead of the standard csp/namespace/classname style of URL.

Allowed IP Addresses

Specifies a comma-separated list of remote IP addresses from which to accept connections. The adapter accepts IP addresses in dotted decimal form. An optional :port designation is supported, so either of the following address formats is acceptable: 192.168.1.22 or 192.168.1.22:3298.

Note:

IP address filtering is a means to control access on private networks, rather than for publicly accessible systems. InterSystems does not recommend relying on IP address filtering as a sole security mechanism, as it is possible for attackers to spoof IP addresses.

If a port number is specified, connections from other ports will be refused.

If the string starts with an exclamation point (!) character, the inbound adapter initiates the connection rather than waiting for an incoming connection request. The inbound adapter initiates the connection to the specified address and then waits for a message. In this case, only one address may be given, and if a port is specified, it supersedes the value of the Port setting; otherwise, the Port setting is used.

Call Interval

Specifies the number of seconds that the adapter will listen for incoming data from its configured source, before checking for a shutdown signal from the production framework.

If the adapter finds input, it acquires the data and passes it to the business service. The business service processes the data, and then the adapter immediately begins waiting for new input. This cycle continues whenever the production is running and the business service is enabled and scheduled to be active.

The default is 5 seconds. The minimum is 0.1 seconds.

Enable Standard Requests

If this setting is true, the adapter can also receive SOAP requests in the usual way (bypassing the TCP connection). The default is false.

Generate SuperSession ID

This property controls whether the message will have a SuperSessionID, which can be used to identify messages that cross from one namespace to another. If this property is set, the business service first checks the HTTP header of the inbound message for a SuperSession ID. If it has a SuperSessionID value, it uses it; otherwise, it generates a new SuperSession value. It sets the SuperSesssion value in the production message and can also return the value in any HTTP response it sends to the caller.

Job Per Connection

If this setting is true, the adapter spawns a new job to handle each incoming TCP connection and allows simultaneous handling of multiple connections. When false, it does not spawn a new job for each connection. The default is true.

Local Interface

Specifies the network interface through which the connection should go. Select a value from the list or type a value. An empty value means use any interface.

OS Accept Connection Queue Size

Specifies the number of incoming connections should the operating system should hold open. Set to 0 if only one connection at a time is expected. Set to a large number if many clients will connecting rapidly.

Port

Identifies the TCP port on the local machine where the adapter is listening for SOAP requests. Avoid specifying a port number that is in the range used by the operating system for ephemeral outbound connections.

Read Timeout

Specifies the number of seconds to wait for each successive incoming TCP read operation, following receipt of initial data from the remote TCP port. The default is 5 seconds. The range is 0–600 seconds (a maximum of 10 minutes).

SSL Config

The name of an existing TLS configuration to use to authenticate this connection. This should be a server configuration.

To create and manage TLS configurations, use the Management Portal. See the chapter “Using TLS with InterSystems IRIS” in the Security Administration Guide. The first field on the Edit SSL/TLS Configuration page is Configuration Name. Use this string as the value for the SSLConfig setting.

Stay Connected

Specifies whether to keep the connection open between requests.

  • If this setting is 0, the adapter will disconnect immediately after every event.

  • If this setting is -1, the adapter auto-connects on startup and then stays connected.

  • This setting can also be positive (which specifies the idle time, in seconds), but such a value is not useful for this adapter, which works by polling. If the idle time is longer than the polling interval (that is, the CallInterval) the adapter stays connected all the time. If the idle time is shorter than the polling interval, the adapter disconnects and reconnects at every polling interval.
