Parameter NameDescriptionDefault Value
synapse.threads.coreThe initial number of synapse threads in the pool. This parameter is applicable only if the Iterate or the Clone mediator is used to handle a higher load. The number of threads specified for this parameter should be increased as required to balance an increased load.20
synapse.threads.maxThe maximum number of synapse threads in the pool. This parameter is applicable only if the Iterate or the Clone mediator is used to handle a higher load. The number of threads specified for this parameter should be increased as required to balance an increased load.100
synapse.threads.keepaliveThe keep-alive time for extra threads defined in milliseconds. This parameter is applicable only if the Iterate or the Clone mediator is used to handle a higher load.5
synapse.threads.qlenThe length of the queue that is used to hold the runnable tasks to be executed by the pool. This parameter is applicable only if the Iterate or the Clone mediator is used to handle a higher load.10
synapse.threads.groupThe name of the thread group.synapse-thread-group
synapse.threads.idprefixThe prefix of each thread name.SynapseWorker
synapse.sal.endpoints.session.timeout.defaultThe session time-out time for the session aware load balance endpoint given in milliseconds.600000

The maximum number of milliseconds within which a response for the request should be received. A response which arrives after the specified number of seconds cannot be correlated with the request. Hence, a warning all be logged and the request will be dropped. This parameter is also referred to as the time-out handler120000
statistics.clean.enableIf this parameter is set to true, all the existing statistics would be cleared before processing a request. This is recommended if you want to increase the processing speed.false
synapse.commons.json.preserve.namespacePreserves the namespace declarations in the JSON output in XML to JSON transformations.false
synapse.xpath.dom.failover.enabled

If this parameter is set to true , it will be possible for ESB to switch to xpath 2.0. The default value for this parameter is false since xpath 2.0 evaluations can cause performance degradation.

Note

WSO2 EI uses the Saxon Home Edition in implementing XPATH 2.0 functionalities, and thus supports all the functions that are shipped with it. For more information on the supported functions, see Saxon Documentation.

Time-out
Time-out
The back end service to which a request has been sent are repeatedly called back for responses at time intervals specified for this parameter. Any endpoints have timed out are identified during these time intervals, and they are no longer called back. Note that specifying a lower value for this parameter results in a higher overhead on the system.15 (seconds)
