IPv6 infrastructure

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

Sybase applications are IPv6-aware. All code to turn the Cluster Edition 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:

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

• Connection Handler

• RPC mechanisms

• Job Scheduler Task / Agent session connection

• Network Host API

• UDP Message support for sybsendmsg

• Component Integration Services connectivity

• Host / name resolving

• XML URL connection handler

• Auditing for client address data

The following functional mechanisms in the Cluster Edition do not support IPv6. These mechanisms in the Cluster Edition are IPv6-unaware:

• Java support

• License Management Server

• LDAP driver

• Private interconnect among various instances in cluster.
