CACHE_INVALIDATION_TIMEOUT (Parameter)

Parameter: CACHE_INVALIDATION_TIMEOUT

Definition

The timeout in milliseconds for waiting acknowledgments for a cache invalidation request from all the system instances except the updater

Description and Use

When the updater instance modifies some objects, a cache invalidation request is sent to the other instances in the SAP CC Core Server system through the multicast service.

The CACHE_INVALIDATION_TIMEOUT parameter defines the maximum time in milliseconds for receiving all the instance acknowledgments for cache invalidation request.

If the acknowledgments are not received before the timeout expiration, all the data modifications are rolled back by the updater instance and a com.highdeal.hci.ServerFailure exception is returned to the client application or system connected to this updater instance.

Syntax and Constraints

Defined Constraints

The SAP CC Core Server system verifies the following constraints:

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.

Groups

Instance Type

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

updater

Default Value (Factory Settings)

The predefined default value is:

Instance Type	Value
Updater	`10000`

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:

Updater instances

The parameter must be greater than or equal to 1000 .
