RAC: add new node to cluster


15.04.2015
by Kamil Stawiarski

  • Add a new node to RAC

Check the network configuration for both nodes

On the with active cluster, check the network configuration

[root@lodzio ~]# oifcfg getif
eth0  192.168.56.0  global  public
eth1  10.0.0.0  global  cluster_interconnect

Configure appropriate network devices on the node, which I want to add

[root@miodzio ~]# vim /etc/sysconfig/network-scripts/ifcfg-eth1 
[root@miodzio ~]# cat !$
cat /etc/sysconfig/network-scripts/ifcfg-eth1
DEVICE=eth1

IPV6INIT=no

[root@miodzio ~]# ifup eth1

Create appropriate user on the new node:

[root@miodzio ~]# id oracle
uid=54321(oracle) gid=54321(oinstall) grupy=54321(oinstall),54322(dba)

Configure shared storage – first install ASMLib drivers (if you are using ASMLib :))

You can download oracleasmlib-2.0.4-1.el6.x86_64.rpm from here: http://www.oracle.com/technetwork/server-storage/linux/asmlib/ol6-1709075.html

Ensure that SELinux won’t be a problem:

[root@miodzio ~]# setenforce 0
[root@miodzio ~]# vim /etc/sysconfig/selinux 
[root@miodzio ~]# cat !$
cat /etc/sysconfig/selinux

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=permissive
# SELINUXTYPE= can take one of these two values:
#     targeted - Targeted processes are protected,
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted 

Now we can perfom a library configuration (be sure to set the same ownership as in other RAC nodes)

[root@miodzio ~]# /etc/init.d/oracleasm configure 
Configuring the Oracle ASM library driver.

This will configure the on-boot properties of the Oracle ASM library
driver.  The following questions will determine whether the driver is
loaded on boot and what permissions it will have.  The current values
will be shown in brackets ('[]').  Hitting <ENTER> without typing an
answer will keep that current value.  Ctrl-C will abort.

Default user to own the driver interface []: oracle
Default group to own the driver interface []: oinstall
Start Oracle ASM library driver on boot (y/n) [n]: y
Scan for Oracle ASM disks on boot (y/n) [y]: 
Writing Oracle ASM library driver configuration: done
Initializing the Oracle ASMLib driver:                     [  OK  ]
Scanning the system for Oracle ASMLib disks:               [  OK  ]

Check the existance of appropriate devices:

[root@miodzio ~]# ls -al /dev/oracleasm/disks/
razem 0
drwxr-xr-x. 1 root   root         0 04-15 12:42 .
drwxr-xr-x. 4 root   root         0 04-15 12:42 ..
brw-rw----. 1 oracle oinstall 8, 17 04-15 12:49 ASMGRID

Now we can create install directories and start installation procedure

[root@miodzio ~]# mkdir /u01
[root@miodzio ~]# chown oracle:oinstall /u01

Set the same DNS configuration files as in other RAC nodes. Of course you have to update the DNS configuration for thew node names.

[root@miodzio ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0 | grep DNS
DNS1=192.168.56.121
DNS2=8.8.8.8
[root@miodzio ~]# cat /etc/resolv.conf
# Generated by NetworkManager


# No nameservers found; try putting DNS servers into your
# ifcfg files in /etc/sysconfig/network-scripts like so:

Now you have to configure SSH passwordless connectivity between nodes

Generate RSA public and private keys on the new node

Saving inventory on nodes (Wednesday, April 15, 2015 1:38:16 PM CEST)
.                                                               100% Done.
Save inventory complete
WARNING:A new inventory has been created on one or more nodes in this session. However, it has not yet been registered as the central inventory of this system. 
To register the new inventory please run the script at '/u01/app/oraInventory/orainstRoot.sh' with root privileges on nodes 'miodzio'.
If you do not register the inventory, you may not be able to update or patch the products you installed.
The following configuration scripts need to be executed as the "root" user in each new cluster node. Each script in the list below is followed by a list of nodes.
/u01/app/oraInventory/orainstRoot.sh #On nodes miodzio
/u01/app/11.2.0/grid/root.sh #On nodes miodzio
To execute the configuration scripts:
    1. Open a terminal window
    2. Log in as "root"
    3. Run the scripts in each cluster node
    
The Cluster Node Addition of /u01/app/11.2.0/grid was successful.
Please check '/tmp/silentInstall.log' for more details.

Now we can follow the instruction to run scripts as root:
