Over the past decade TCP/IP has become the industry standard protocol. To streamline our development and support processes, Actian Corporation will drop support for a number of obsolete network protocol drivers in the next major release of Ingres (post Ingres 10.1). These protocols are no longer used and in many cases have become unsupportable. A newer version of some of the drivers is now available. While these changes do not affect the current or any past release of Ingres, the announcement is being made now to inform our customers. If a dropped protocol is one used in your environment (see list below), please contact Actian Support to identify a migration plan. This announcement will be formally provided in the 10.0.1 Service Pack and 10.1 READMEs currently under development.

This document discusses the protocols to be dropped and also provides a detailed list of the protocols that will continue to be supported.

One of the protocols, wintcp on Windows, has been deprecated for a couple of releases. Deprecation is different from (and less severe than) being dropped. “Deprecation” means that the protocol is still available but receives no new enhancements and minimal maintenance. The newer driver (tcp_ip in this case) should be used instead. “Dropped” means that the protocol will no longer be available. Note that beginning with Ingres 9.3, the protocol wintcp has been upgraded automatically to tcp_ip during installation. Other dropped protocols, if currently used (which is very unlikely), must be changed manually.

Note: All platforms continue to support the industry standard protocol TCP/IP (default is tcp_ip on Linux, UNIX, and Windows; tcp_dec on VMS; and tcp_ibm on the mainframe). Other supported protocols are listed below.

Network Protocol Drivers Being DROPPED

Windows:

lanman – Microsoft Lan Manager
nvlspx – Novell SPX/IPX
wintcp – Winsock 1.1 TCP/IP

UNIX, Linux:

async – BLAST serial protocol
decnet – DECnet (still used and supported on VMS, but not from UNIX)
iso_oslan – ISO OSI Local Area Network
iso_x25 – ISO OSI X25
nvlspx - Novell SPX/IPX
sna_lu62 – SNA LU62 (was available only on Oracle/Sun Solaris, HP-UX, and IBM AIX)

VMS:

async – BLAST serial protocol
nvlspx - Novell SPX/IPX
sna_lu0 – SNA LU0
tcp_wol – Wollongong or Multinet running Wollongong emulation TCP/IP

Network Protocol Drivers Still SUPPORTED

Windows:

tcp_ip – Winsock 2 TCP/IP

UNIX, Linux:

tcp_ip, sock_tcp_ip – TCP/IP including IPv6 support
tcp_ipv4, tcp_ip (if IPv6 not available on OS), sockets (if HP-UX TLI used for tcp_ip) – TCP/IP (v4 only)
tli_tcp_ip or tcp_ip – TCP/IP using Transport Layer Interface (TLI) rather than sockets (HP-UX only)

VMS:

decnet – DECnet (built into VMS OS)
tcp_dec – TCP/IP Services for OpenVMS, Multinet TCP/IP, and TCPWARE
