Back Out IPv6 Support
To completely back out IPv6 support, you must use the old driver, which supports IPv4 only. The old driver is renamed to tcp_ipv4 on UNIX and Linux. The old driver is expected to be made obsolete in a future release of Ingres.
To back out the enhanced tcp_ip Ingres protocol driver
1. Back out network protocol for servers with tcp_ip.status = ON
UNIX/Linux:
iisetres ii.machine.gcc.*.tcp_ip.status OFF (Unix/Linux)
iisetres ii.machine.gcc.*.tcp_ipv4.status ON (Unix/Linux)
iisetres ii.machine.gcc.*.tcp_ipv4.port II (Unix/Linux)
iisetres ii.machine.gcd.*.tcp_ip.status OFF (All platforms)
iisetres ii.machine.gcd.*.tcp_ipv4.status ON (Unix/Linux)
iisetres ii.machine.gcd.*.tcp_ipv4.port II7 (Unix/Linux)
Set the port value to same as that used by the same server for tcp_ip.
VMS:
define/group II_TCPIP_VERSION 4
or
define/system II_TCPIP_VERSION 4
2. Back out local IPC protocol (Linux and UNIX only):
ingsetenv II_GC_PROT tcp_ipv4
3. Back out network and local IPC protocol (Linux and UNIX only):
set II_TCPIP_VERSION=4
or
ingsetenv II_TCPIP_VERSION 4
Note: This step is equivalent to steps 1 and 2 above, and is the simplest way to back out to the IPv4-only driver on Linux and UNIX.
