II_GC_PROT Environment Variable--Set IPC Protocol
The II_GC_PROT environment variable sets the local interprocess communications (IPC) protocol. You can set this variable using the ingsetenv command.
Note: II_GC_PROT should be changed only when Ingres (including tools such as IVM) is completely shut down; otherwise, failures will occur for Ingres shutdown, startup, and connection requests.
This variable has the following format:
II_GC_PROT = protocol
protocol
Specifies the local IPC protocol as one of the following:
TCP_IP
(Default for Linux and UNIX) Uses the current TCP_IP protocol driver.
Windows: TCP_IP is the only valid value. The default IPC protocol is named pipes.
TCP_IPV4
(Linux and UNIX only) Uses the previous version of the TCP_IP protocol driver, which supports IPv4 addresses only.
