Adaptive Server Enterprise

Before starting Adaptive Server for IPv6-aware operations, make sure that
your infrastructure is correctly set up. Once your operating system is correctly
configured, an IPv6

connection handler

can be configured and enabled.

Configuring and enabling the IPv6

connection handler

requires adding an

additional DCL entry. A single Adaptive Server configuration can typically
carry up to 32

connection handler

assignments within the DCL.

For example if you have a Site-local setup with two domains administrated
under the nameserver setup:

sybase.com - being responsible for all IPv4 networking applications

v6.sybase.com - being responsible for all IPv6 networking applications

The DCL entry for Adaptive Server to start named “SYBASE” on the host
“revival” for port 17100 would typically look like:

SYBASE

master tcp ether revival.sybase.com 17100

query tcp ether revival.sybase.com 17100

master tcp ether revival.v6.sybase.com 17100

query tcp ether revival.v6.sybase.com 17100

In the above example, when Adaptive Server is started with IPv6-awareness it
creates two

connection handlers

. One listens on port 17100 for incoming IPv4

Clients connection requests, and the other listens on port 17100 for incoming
IPv6 Clients connection requests.

Troubleshooting

This section describes how to correct some common situations that may cause
a server to not start.

Server fails to start

If a server fails to start with the following message, the port number specified
in the interfaces file may be in use:

00:00000:00002:2003/09/22 12:37:23.63 kernel network name SERV_CORPNET, type

ether, port 4559, filter NONE
