SIP Container (sipContainer)

SIP Container (sipContainer)

Configuration for the SIP servlets container

Name Type Default Description

addIBMPOLBMsg boolean true By default, the IBM-PO header is set in any request. The header field is used internally and defines the outbound interface that should be used when sending a message to the destination. Set the custom property to false avoids setting the header field when a request is sent over a loopback adapter.

dispatcherMessageQueueSize int 1000 The maximum number of tasks that a SIP container queue can contain before it declares an overload state.

enableSetLBOutboundIF boolean false On a multi-homed host, when a loopback adapter is used as an outbound interface, the custom property should be set to true to mandate the use of the selected outbound interface. In case the custom property is not applied or set to false, the container shall apply default behavior of interface selection.

enableSetOutboundIF boolean false On a multi-homed host, the custom property should be set to true to mandate the use of a particular outbound interface. In case the custom property is not applied or set to false, the container shall apply default behavior of interface selection.

invalidateSessionOnShutdown boolean false When the SIP container shuts down, the sessions are no longer valid. By default, sessions remain active until they expire.

markInternalResponse boolean false Mark internally generated responses by setting the com.ibm.websphere.sip.container.internal.message attribute on the response.

maxAppSessions int 120000 The maximum number of SIP application sessions allowed at once.

maxMessageRate int 5000 The maximum number of messages allowed per averaging period.

maxResponseTime A period of time with millisecond precision 0ms The maximum response time allowed in milliseconds. When set to 0, the response time is unlimited. Specify a positive integer followed by a unit of time, which can be hours (h), minutes (m), seconds (s), or milliseconds (ms). For example, specify 500 milliseconds as 500ms. We can include multiple values in a single entry. For example, 1s500ms is equivalent to 1.5 seconds.

messageQueueBurstFactor int 10 The burst factor for the message queue size. The message queue size is set to (dispatcher message queue size) * (message queue burst factor). Set a burst factor handles bursts in traffic by providing additional space in the queue before new messages are dropped.

msgArrivalTimeAttr boolean false Save the message arrival time as an attribute of the message.

sipIntrospect
Configuration for the SIP introspect

VERBOSE

SUCCINCT The level of SIP state details to include when generating server dump.
SUCCINCT

sipTasksDispatcher
Configuration for the executor of parallel SIP tasks
