CACHE_WARMUP_THREAD_COUNT (Parameter)

Parameter: CACHE_WARMUP_THREAD_COUNT

Definition

The number of threads reserved for processing the cache warm-up

Description and Use

This system parameter defines the number of processing threads reserved for performing the cache warm-up function in each instance of the SAP CC system.

If the value is 0, there is no cache warm-up.

System Configuration (Advanced): Tuning

Fine-Tuning the Parameter Value

You can fine-tune the parameter values. For each type of instances in your SAP CC system, see the SAP CC Sizing and Performance Tuning Guide.

Syntax and Constraints

Defined Constraints

The SAP CC Core Server system verifies the following constraints:

Instance Type	Constraint
Rater instances	The parameter must be greater than or equal to 0 . The constraint(s) of the parameter SQLHELPER_CONNECTION_COUNT must be verified (as part of these constraint(s)). The constraint(s) of the parameter RATING_SESSION_SQLHELPER_CONNECTION_COUNT must be verified (as part of these constraint(s)).
Guider instances	The parameter must be greater than or equal to 0 . The constraint(s) of the parameter SQLHELPER_CONNECTION_COUNT must be verified (as part of these constraint(s)).

Access (RO/RW)

RW(+): Dynamic Read / Static and Dynamic Write

An immediate change is possible but is temporary. When it is relevant, change the permanent settings used by the SAP CC Core Server system when it restarts.

Use the Admin+ user interface to change the runtime values or the permanent values of this system parameter in an instance of the SAP CC Core Server system or in multiple instances.

Groups

Instance Types

This system parameter is available in the following types of instances in a running SAP CC Core Server system:

rater, guider

Default Values (Factory Settings)

The predefined default values are:

Instance Type	Value
Rater	`0`
Guider	`0`

You can use a default value to reset the runtime value or the restart value (persistent) in the Admin+ user interface.

Note

A default value is part of the factory settings of the SAP CC Core Server systems. It differs from the original value set during the installation or after the Customizing activities.

In Admin+, you can reset a parameter value to this default value, but it is not recommended:

This value may differ from the original value set during the installation of your SAP CC system.
Note that it may also differ from the value defined by the implementation project team and set during the Implementation Phase of the integration project.

Verify the values in your running SAP CC systems before to use the reset command.

Constraints

The SAP CC system checks the following constraints:

Rater instances	The parameter must be greater than or equal to 0 . The constraint(s) of the parameter SQLHELPER_CONNECTION_COUNT must be verified (as part of these constraint(s)). The constraint(s) of the parameter RATING_SESSION_SQLHELPER_CONNECTION_COUNT must be verified (as part of these constraint(s)).
Guider instances	The parameter must be greater than or equal to 0 . The constraint(s) of the parameter SQLHELPER_CONNECTION_COUNT must be verified (as part of these constraint(s)).
