IPv6 support

•IPv6-enabled – an application that, in addition to being IPv6-aware, takes advantage of some IPv6 features.

•IPv6-required – an application that requires some IPv6 features and cannot operate over IPv4.

IPv6 Infrastructure:

IPv6 infrastructure

Dual Stack infrastructure implements both IPv4 and IPv6. This is the recommended infrastructure implementation for using Adaptive Server Enterprise as an IPv6-aware server.

Sybase applications are IPv6-aware. All code to turn Sybase™ Adaptive Server and the Open Client/Server components IPv6-aware was done using the IETF designed primitives, see “Creating or converting for IPv6-aware applications.” The following matrix lists the platform run-time requirements and the specific product and its release version:

Microsoft Server 2003		12.5.3a and 15.0	12.5 and 15.0

Linux RHEL 3.0		15.0	12.5 and 15.0

Many Sybase products that are Open Client/Server based like XP Server, Backup Server, Replication Server and Open Switch became automatically IPv6-aware due to the layered Open Client Transport Control Layer (CTlib- >NETlib) which is IPv6-aware for network-socket operations. An important note is that any DBlib based Open Client product is not IPv6-aware.

For Adaptive Server Enterprise being IPv6-aware is a complex issue because some components within the ASE are 3rd party components and are not yet IPv6-aware. To understand how this impacts Adaptive Server Enterprise the following list shows all functional mechanisms of Adaptive Server Enterprise that are IPv6-aware with respect to the platform / release matrix above:
