IPv6 support
64 Adaptive Server Enterprise
• 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:
Table 5-3: IPv6 support
Many Sybase products that are Open Client/Se rver 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:
