Adding a node to a 12cR1 RAC cluster
Manually
This post is for how to add node to 12cR1 cluster
manually in CLI mode.
Here I have used Oracle Linux 6.5 with UEK2
server as a host. Below are my existing 2 node configuration details.
rac121:ccbdb1>.
oraenv
ORACLE_SID =
[ccbdb1] ? +ASM1
The Oracle base has
been changed from /u01/app/oracle to /grid/app/oracle
rac121:+ASM1>oifcfg
getif
eth0 192.168.1.0
global public
eth1 10.10.10.0
global cluster_interconnect
eth2 20.20.20.0
global cluster_interconnect
eth3 30.30.30.0
global cluster_interconnect
Here I am using oracle user for both Grid
and RDBMS Binary. Also make sure the new host will be identical to configuration with existing host.
Adding the node
High level steps need to follow in order to
adding node to the cluster are:
·
Install Operating System OEL 6.5 x64 UEK2
·
Install required rpm as per existing 2 node
host
·
Configure network (Public and Private)
·
Configure kernel parameters, storage (asmlib)
and DNS
·
First Adding Grid Binary then after RDBMS
Binary and register to OCR
Configure yum and install required oracle
related package using oracle-rdbms-server-12cR1-preinstall package.
Also validate the below configuration as
per existing 2 nodes:
·
configure necessary required rules in
firewall to allow access or disable the firewall as your configuration.
·
Change the setting in /etc/sysconfig/selinux
to permissive
·
Here we are using CTS not NTP, so make sure
need to remove or rename the /etc/ntp.conf and disable the service.
·
Mount all share storage drive in new host
with required permission.
·
Create the directory structure as per
existing node configuration.
·
Configure user equivalence between all nodes.
