Jeopardy Management System Configuration
All the parameters of Jeopardy Management System have default values and no parameter value required to deploy and run Jeopardy Management System in basic mode. You might change the following parameters to tune the performance of the Jeopardy Management System.
Jeopardy Management Tuning Parameters
The Jeopardy Management Tuning Parameters are as follows:
Risk Threshold
Set this parameter to specify a percentile increase over a typical duration beyond which a task can be considered to be running in a hazard region. For example, if a typical duration of a process component is 60 minutes and if risk the threshold is 50, any plan item that is running for more than 90 minutes is considered to be running in a hazard region. The default value is 25 percentile points.
Out of Scope Threshold
Set this parameter to specify Percentile increase over maximum duration beyond which an execution can be considered running out of scope for jeopardy detection. And no further jeopardy monitoring is performed on the plan. For example, if the maximum duration of a process component is 60 minutes and if the out of scope threshold is 100, any plan item that is running for more than 120 minutes is considered as out of scope and the Jeopardy Management System stops monitoring the plan.
Time Window Value/Time Window Unit
The Configuration parameter
Time window value
and
Time Window Unit
are combined to determine the
Time window or Chronon
to which plan items of execution plans belong in the Jeopardy Management System. It is a user-defined interval of time during which any execution of any plan item would result in grouping the plan item together. Configure this value based on the execution characteristics of process components in the fulfillment ecosystem. This value is used by the Jeopardy Management System to cluster plan items in execution to optimize the jeopardy detection cycle.
For example, if fulfillment tasks run by the process components typically take a few days to complete, it is probably meaningless to use seconds or milliseconds to track the progress of a plan item. In this case, you can provide value in terms of hour units. If Jeopardy Management System monitors very fast running plans, Jeopardy Management System requires a Chronon of milliseconds or seconds to accurately predict the jeopardy condition. The default value is 10 Minutes.
Messaging Configuration
Jeopardy Management System piggybacks on message configuration parameters of Order Management Server and no additional configuration required.
Datasource Configuration
Jeopardy Management System piggybacks on data source configuration parameters of Order Management Server and no additional configuration required.
Colocated Jeopardy Mode
Colocated Jeopardy mode only supports "Cache" as the second-level data store. The existing data store options like File and ActiveSpace are not supported.
Two tables are responsible for the cache data store. The tables are:
TIME_WINDOW
DAMPENING_CRITERIA
Change in Jeopardy Management System
If the node status has not been set to STARTED, none of the Jeopardy Management System requests are processed. Currently, all Jeopardy Management System requests are processed by the state machine. Jeopardy Management System waits for the node to achieve the STARTED state to begin jeopardy monitoring.
