Set IPC Protocol
The local IPC protocols are:
• TCP_IP: On Linux, TCP_IP is the default IPC protocol. On Windows, Named Pipes is the default, with TCP_IP available as an alternative.
• TCP_IPV4: Linux only. Uses the previous version of the TCP_IP protocol driver and supports only IPv4 addresses.
Before configuring IPC Protocol, ensure the following:
• Shut down the Actian Ingres installation.
• Directory is writable by the installation owner.
• Use different directories for each installation if there are multiple installations on a single machine.
To configure IPC Protocol:
1. Shut down the installation:
ingstop
2. Set the IPC driver:
iisetres ii.host1.config.gca_driver tcp_ipv4
3. Set the environment variable (only if gca_driver is set to unix):
ingsetenv II_SOCK_PATH /some_directory
Note: If you skip this step, the environment variable is set in the /tmp directory, which is not a recommended option.
4. Start the installation:
ingstart
