This article is about how to add a new node to LINUX x86-64 RAC. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Linux x86 adds a node as follows:

1 prepare public network and private network IP

2 change / etc/hosts

3 install the corresponding package

4 configure shared disk

5 configure environment variables

6 configure SSH mutual trust

. / sshUserSetup.sh-user grid-hosts "12crac2 mysql-1"-noPromptPassphrase

. / sshUserSetup.sh-user oracle-hosts "12crac2 mysql-1"-noPromptPassphrase

7 perform pre-installation check

Cd $ORACLE_HOME/bin

. / runcluvfy.sh stage-pre nodeadd-n mysql-1-fixup-verbose

8 execute add_node.sh

Enter the oui/ bin subdirectory of the GI installation directory and execute the following command to add the new node node2 to the cluster:

Cd $ORACLE_BASE

Cd. / oui/bin/

Export IGNORE_PREADDNODE_CHECKS=Y

. / addNode.sh-silent "CLUSTER_NEW_NODES= {mysql-1}"CLUSTER_NEW_VIRTUAL_HOSTNAMES= {mysql-1-vip}"CLUSTER_NEW_PRIVATE_NODE_NAMES= {mysql-1-priv}" & > ~ / add_node.log

9 newly added machines execute root.sh of CRS

$ORACLE_HOME/oraInventory/orainstRoot.sh # On nodes mysql-1

$ORACLE_HOME/root.sh # On nodes mysql-1

If the execution fails, deconfig is required to execute it again.

/ opt/crs/product/crs/install/rootcrs.pl-deconfig-force

10 add RDBMS to new machines

Add rdbms as oracle user:

$ORACLE_HOME/oui/bin/addNode.sh "CLUSTER_NEW_NODES= {mysql-1}"

Finally, dbca chooses to add instances.

Remember to add logfile group:

Alter database add logfile thread 2 ('+ data') size 50m

Alter database add logfile thread 2 ('+ data') size 50m

Alter database enable thread 2

Select * from v$thread

Or silently add a new instance:

Dbca-silent-addInstance-nodeList mysql-1-gdbName racdb-instanceName racdb2-sysDBAUserName sys-sysDBAPassword oracle
