Bookshelf v7.5: Setting Workflow Process Manager Parameters for Performance

Workflow Process Manager requires configuration to common parameters available in Siebel eBusiness Applications. Table 4 lists some of these parameters and includes suggested settings. For detailed definitions of these parameters, refer to Siebel Server Administration Guide.

Table 4. Workflow Process Manager Parameters and Settings
Parameter	Alias	Suggested Setting or Comments
Maximum MT Servers	MaxMTServers	MaxMTServers = target #users / users/AOM
Minimum MT Servers	MinMTServers	MinMTServers = MaxMTServers Setting MinMTServers less than MaxMTServers can cause a delay of service for new users as additional multithreaded processes get initialized.
Maximum Tasks	MaxTasks	20% target #users For example, for 500 users, set MaxMTServers=5 and MaxTasks=100.
DB Multiplex - Min Number of Dedicated DB Connections	MinSharedDbConns	10% target #users
DB Multiplex - Max Number of Shared DB Connections	MaxSharedDbConns	10% target #users
DB Multiplex - Min Number of Shared DB Connections	MinTrxDbConns	10% target #users
OM-Model Cache Maximum	ModelCacheMax	Determines the size of the cache for model objects in AOM-based server components, such as Workflow Process Manager. For more information about this parameter, refer to Siebel Server Administration Guide.
Honor MaxTasks	HonorMaxTasks	If HonorMaxTasks is set to TRUE, then once MaxTasks is reached, all further requests are rejected instead of being queued
Recycle Factor	RecycleFactor	If excessive memory usage exists, set this parameter to periodically restart the Workflow Process Manager component.

NOTE: With the setting Bypasshandler = TRUE, there will be no regular component logging unless the component experiences difficulties and generates an error message.

NOTE: Closely monitor the WFProcMgr process usage during a steady state run, and then adjust the parameters according to your observations.
