PARTITION_SWITCH_TIMEOUT (Parameter)

Parameter: PARTITION_SWITCH_TIMEOUT

Definition

The timeout in milliseconds for the detection of a failed partition switch. This timeout is for each partition.

Description and Use

The timeout in milliseconds for the detection of a failed partition switch. When a partition is switched from an instance (rater or guider) to a new instance, the dispatcher waits for all the messages to be processed by the old instance. The old instance may fail to answer in a timely manner, blocking entirely the partition switch. As a consequence, the dispatcher forbids the new instance to start. The recommended value for this parameter is the typical timeout expected on SAP CC for processing a request (generally between 1,000 ms and 10,000 ms). A value of 0 for this parameter means that there is no timeout when a partition switch occurs. In this case, a partition switch may fail indefinitely.

Syntax and Constraints

Defined Constraints

The SAP CC Core Server system verifies the following constraints:

Name

PARTITION_SWITCH_TIMEOUT

The timeout in milliseconds for the detection of a failed partition switch. This timeout is for each partition.

Category Parameter

Type Integer

Access (RO/RW)

RW(-): Dynamic Read / Static Write

An immediate change is not possible. For a deferred and permanent change, use the set command of the Admin+ user interface to change the parameter value for a specific type of instance in the SAP CC Core Server system. A restart is needed for permanent changes.

System: Network and Communication

Instance Type

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

dispatcher

Default Value (Factory Settings)

The predefined default value is:

Instance Type	Value
Dispatcher	`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:

Dispatcher instances

The parameter must be greater than or equal to 0 .
