COLLECTOR_RTT (Parameter)

Parameter: COLLECTOR_RTT

Definition

The estimated network round trip time in milliseconds

Description and Use

This system parameter defines the estimated network round trip time (in milliseconds). This is the time for a message handled by the message collector to be transmitted on the network.

This parameter is taken into account for timeout calculation when using stateless and stateful services of the rater and guider instances.

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 .
Guider instances	The parameter must be greater than or equal to 0 .
Updater instances	The parameter must be greater than or equal to 0 .
Bulkloader instances	The parameter must be greater than or equal to 0 .
Taxer instances	The parameter must be greater than or equal to 0 .
Dispatcher instances	The parameter must be greater than or equal to 0 .

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.

System: Network and Communication

Instance Types

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

rater, guider, updater, bulkloader, taxer, dispatcher

Default Values (Factory Settings)

The predefined default values are:

Instance Type	Value
Rater	`100`
Guider	`100`
Updater	`100`
Bulkloader	`100`
Taxer	`100`
Dispatcher	`100`

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 .
Guider instances	The parameter must be greater than or equal to 0 .
Updater instances	The parameter must be greater than or equal to 0 .
Bulkloader instances	The parameter must be greater than or equal to 0 .
Taxer instances	The parameter must be greater than or equal to 0 .
Dispatcher instances	The parameter must be greater than or equal to 0 .
