How to replace a private network Nic In an oracle cluster.

Today is, and the learning progress is also in full swing. Today, I will record a small part of the experiment.

We know that the RAC network has a private network and a public network. The public network provides customer access requests and the private network provides oracle's cache fusion and node heartbeat functions, in 11G R2, four private networks can be executed for cache fusion.

But when I started the installation, I ignored it. How can I modify it after the installation? This step can simulate how to add a private Nic for oracle RAC. If the NIC is damaged.

In addition, there are several situations for network adjustment, such as changing the private host name, changing the network segment and mask, changing the private address, changing the mtu of the private network, and changing the private Nic Subnet or mask.

Today we will talk about how to change the private network card. In this case, you need to use a tool named oracle interface configuration assistant (oifcfg ).

Before 11G r2, oracle stored the network interface name and subnet information in ocr, so you can use oifcfg to complete the modification:

1. add and delete Private Network Interfaces

Add a private network interface

$ ORA_CRS_HOME/bin/oifcfg setif-global/: cluster_interconnect

Delete A Private Network Interface

$ ORA_CRS_HOME/bin/oifcfg delif-global/

2. View Nic changes

$ ORA_CRS_HOME/bin/oifcfg getif

3. Restart the Cluster

Crsctl stop crs

Crsctl start crs

So how can I modify the Intranet for oracle 11G R2 or later?

In 11.2gi, the private network configuration is not saved in ocr, but in the gpnp profile file. This file is an xml file. Manual Editing is not recommended. before configuring the private network

First, back up the file for subsequent operations. Because my lab environment is exactly 11.2.0.4, the actual modification process is recorded immediately.

1. Back up the gpnp profile file (each node must be backed up ).

Currently, the name of the private network device connected to the cluster is eth3. You need to change the name of the private network device in the cluster from eth3 to eth1 and eth2.

3. Add new internal cluster connections

6. Disable the cluster, disable the crs service, and restart the cluster on all nodes.
