Switch IPv4 to IPv6 Applitaction Server Java

Hi,

I have a question about the switch IPv4 to IPv6 in the AS Java.

Do i have to change the parameter java.net.preferIPv6Addresses? Where do I do? or only set envioroment variable: SAP_IPv6_ACTIVE=1

My system is Process Orchestration.

Best Regards,

EDRS.
