IPv6 Infrastructure

Use SAP ASE as an IPv6-aware server only in a dual-stack infrastructure, which implements both IPv4 and IPv6.

SAP applications are IPv6-aware, using the IETF designed primitives.

Many SAP ASE 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. DBlib-based Open Client products are not IPv6-aware.

Some third-party components in SAP ASE are not yet IPv6-aware. The functional mechanisms of SAP ASE that are IPv6-aware with respect to the platform / release matrix include:

The following functional mechanisms in SAP ASE do not currently support IPv6:

Before starting SAP ASE for IPv6-aware operations, make sure that your infrastructure is correctly set up. Once your operating system is correctly configured, you can configure and enable an IPv6 connection handler. Configuring and enabling the IPv6 connection handler requires an additional DCL entry. A single SAP ASE 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 name server setup:

sybase.com - being responsible for all IPv4 networking applications
v6.sybase.com - being responsible for all IPv6 networking applications
The DCL entry for SAP ASE named “SYBASE” on the host “revival” for port 17100 should look similar to:
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
When SAP ASE 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.
Note: When you start SAP ASE, you can set Trace flag 7815 to capture and log IPv4 and IPv6 client address connection requests and host / name lookups.
