IP_ADDRESS_VERSION (Parameter)

Parameter: IP_ADDRESS_VERSION

Definition

The version of IP addresses which must be used when host names are resolved

Description and Use

This parameter defines the version of the IP addresses which must be taken into account during host name resolution. This parameter gives the possibility to specify whether SAP CC must work with either IPV4 or IPV6 addresses.

Note

Do not specify IPV4 or IPV6 addresses in the instance map if this parameter is respectively set to "IPV6" or "IPV4". This kind of configuration prevents the system to start.

Syntax and Constraints

The possible values are:

IPV4 : Host names are resolved as IPV4 addresses. IPV6 addresses are not taken into account.
IPV6 : Host names are resolved as IPV6 addresses. IPV4 addresses are not taken into account.
preferIPV4 : Host names are resolved as IPV4 address if exists, IPV6 addresses otherwise.
preferIPV6 : Host names are resolved as IPV6 address if exists, IPV4 addresses otherwise.

Instance Types

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

updater, dispatcher

Default Values (Factory Settings)

The predefined default values are:

Instance Type	Value
Updater	`preferIPV4`
Dispatcher	`preferIPV4`

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.
