The Server Request Broker (SRBroker) component routes requests between Siebel Server components, such as from an AOM to a batch component. SRBroker also handles requests between batch components. SRBroker is used whether the components run on the same machine or on different machines.
The default parameter values for SRBroker work well for most deployments. If necessary, adjust the value of the MaxTasks parameter (the default value is 100). MaxTasks determines the maximum number of SRBroker threads (tasks) that can run on the Siebel Server. As necessary, set MaxTasks to a value equal to the number of batch components running on the Siebel Server, plus the number of Siebel Servers in the enterprise, plus 10 (for overhead).
MaxMTServers and MinMTServers determine the maximum and minimum number of SRBroker multithreaded processes that can run on the Siebel Server. Each multithreaded process can run a maximum of MaxTasks/MaxMTServers threads. MaxMTServers and MinMTServers should be kept at their default values of 1. Increasing this value will not increase performance, and will not have any benefit.
CAUTION: Setting MaxTasks parameter values for SRBroker components in such a way that does not meet the above guidelines may result in request failures. See the discussion of the HonorMaxTasks parameter in the following section for more information about how requests submitted to batch components may be handled. (HonorMaxTasks has no effect when set on the SRBRoker or Server Request Processor (SRProc) components.)
By default, the HonorMaxTasks parameter for batch components, such as Workflow Process Manager, is set to FALSE (this setting is recommended). With this setting, if requests are routed by SRBroker to a batch component that has reached the maximum task capacity, the requests will be queued in memory, and processed when tasks become available. Queuing such tasks minimizes the potential of request failure on the batch component due to the MaxTasks value having been reached.
