IPv6 support for Data Protection for SAP

Data Protection for SAP supports both IPv4 and IPv6 for internal communication.

Data Protection for SAP supports both IPv4 and IPv6 for internal communication in that it runs in IPv4, IPv6, and mixed environments on AIX® and Linux™. However, these products do not use IPv6. In a mixed environment, the communication depends on the adapter network settings. There is no option to enforce the use of a specific protocol other than by network configuration. Specifically, the ProLE or acsd service listens for both IPv4 and IPv6 connection requests if the system is configured accordingly. Connection requests to ProLE are made for the addresses that are returned by the system for the respective port on the local host. Connection requests to other systems are made for the addresses that are specified by the user. IPv6 addresses are supported when TCP/IP addresses are specified in a command line or in a profile parameter such as TCP_ADDRESS. However, when the IP address and port are specified in the IPv4 address:service or port format, then the format must be changed to service or port@IP address if the IP address is specified in the IPv6 notation. If a dotted decimal IPv4 address, the traditional format can still be used.

The specification of IPv6 addresses assumes that Data Protection for SAP is used in an environment in which IPv6 is supported by all hardware and software components.
