CHAPTER 5 Setting Up Communications Across the Network

•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 Adaptive Server Enterprise do not support IPv6. These mechanisms in Adaptive Server Enterprise are IPv6- unaware. They will gradually (over time) be become IPv6-aware in follow-on releases:

•Java support

•License Management Server

•LDAP driver

Starting Adaptive Server Enterprise as IPv6-aware

Adaptive Server is IPv6-unaware, by default. To make Adaptive Server IPv6- aware, you must start Adaptive Server with trace flag 7841. This causes Adaptive Server to determine IPv6 availability and makes Adaptive Server IPv6-aware.

See your Network or IT specialist to configure your platforms and Network

Infrastructure correctly for IPv6 support.

A second trace flag, 7815 can be set when you start Adaptive Server which captures and logs address connection requests and host / name lookups.

The IPv6 Adaptive Server traceflags:

•T7841 – Enable Adaptive Server IPv6-awareness

•T7815 – Report all Adaptive Server IPv4 & IPv6 Client address connect requests
