RAC添加節點要點、步驟和遇到的問題：
要點：
1、不需要停其他節點，可以說不影響正在運行的節點。
2、不需要下載安裝介質。
步驟：
--delete
清理失敗的節點：
1. Reconfigure the RDBMS Services in the cluster to take into account node 2 is gone.
1.1 Reconfigure the Service plb1 so that it is only running on the remaining instance.
[oracle@sage ~]$ srvctl modify service -d db112i -s plb1 -n -i db112i1 -f
1.2 Examine the configuration to ensure the service is removed from instance db112i2 and node Thyme.
[oracle@sage ~]$ srvctl status service -d db112i -s plb1
Service plb1 is running on instance(s) db112i1
[root@sage ~]# /opt/app/oracle/product/grid/bin/crsctl stat res -t
..
ora.db112i.plb1.svc
1 ONLINE ONLINE sage
2. Reconfigure the RDBMS Instances in the cluster to take into account node 2 is gone.
2.1. Remove the database instances. As this is an Administrator Managed database this can be performed through dbca. From the RAC Instance Management section in dbca follow the wizard to remove the Instance db112i2 from node 2 thyme.
[oracle@sage ~]$ dbca
[oracle@sage ~]$
[oracle@sage ~]$ srvctl config database -d db112i
Database unique name: db112i
Database name: db112i
Oracle home: /opt/app/oracle/database/11.2/db_1

Start options: open
Stop options: immediate
Database role: PRIMARY
Management policy: AUTOMATIC
Server pools: db112i
Database instances: db112i1
Disk Groups: DATA1

[root@sage ~]# /opt/app/oracle/product/grid/bin/crsctl stat res -t

3. Remove the Node from the RAC Cluster
3.1 Using the Installer remove the failed node from Inventory of the Remaining Node(s)
[oracle@sage ~]$ cd $ORACLE_HOME/oui/bin
[oracle@sage bin]$ ./runInstaller -updateNodeList ORACLE_HOME=/opt/app/oracle/database/11.2/db_1 "CLUSTER_NODES={sage}"
Starting Oracle Universal Installer...
Checking swap space: must be greater than 500 MB. Actual 2601 MB Passed
The inventory pointer is located at /etc/oraInst.loc
The inventory is located at /opt/app/oracle/oraInventory
'UpdateNodeList' was successful.
4. Remove the Node from the Grid Cluster
The process for performing the removal of a failed node has been based on the node deletion processes documented in the Grid and RAC administration guides.
From any node that you are not deleting, run the following commands from the Grid_home/bin directory as root to delete the node from the cluster:
4.1 Stop the VIP resource for the node thyme
[root@sage bin]# ./srvctl stop vip -i thyme
4.2 Remove the VIP for the node thyme
[root@sage bin]# ./srvctl remove vip -i thyme -f
4.3 Check the state of the environment and ensure the VIP for node thyme is removed.
[root@sage bin]# ./crsctl stat res -t
..
ora.sage.vip
1 ONLINE ONLINE sage
..
4.4 Remove node 2, thyme from the Grid Infrastructure/clusterware
# crsctl delete node -n thyme
4.5 As the owner of the Grid Infrastructure Installation perform the following to clean up the Grid Infrastructure inventory on the remaining nodes (in this case node 1, sage).
[root@sage bin]# su - oracle
[oracle@sage ~]$ . oraenv db112i1
[oracle@sage ~]$ cd $ORACLE_HOME/oui/bin
[oracle@sage ~]$ ./runInstaller -updateNodeList ORACLE_HOME=/opt/app/oracle/product/grid "CLUSTER_NODES={sage}" CRS=TRUE -silent
4.6 As root now list the nodes that are a part of the cluster to confirm the node required (thyme) has been removed successfully and the only remaining node in this case is node sage.
At the end of this process only the node sage remains as a part of the cluster.
[root@sage bin]# ./olsnodes
sage
刪除存在的節點：
1.
$ olsnodes -s -t
If the node is pinned, then run the crsctl unpin css command. Otherwise,proceed to the next step.
2.Disable the Oracle Clusterware applications and daemons running on the node.
Run the rootcrs.pl script as root from the Grid_home/crs/install
directory on the node to be deleted, as follows:
# ./rootcrs.pl -deconfig -deinstall -force
Note: Before you run this command, you must stop the EMAGENT, as follows:
$ emctl stop dbconsole
3.From any node that you are not deleting
# crsctl delete node -n node_to_be_deleted
4.On the node you want to delete, run the following command as the user that
installed Oracle Clusterware from the Grid_home/oui/bin directory where
node_to_be_deleted is the name of the node that you are deleting:
$ ./runInstaller -updateNodeList ORACLE_HOME=Grid_home "CLUSTER_NODES=
{node_to_be_deleted}" CRS=TRUE -silent -local
5.For a local home, deinstall the Oracle Clusterware home from the node that
you want to delete, as follows, by running the following command, where
Grid_home is the path defined for the Oracle Clusterware home:
$ Grid_home/deinstall/deinstall –local
Caution: If you do not specify the -local flag, then the command removes the Grid Infrastructure home from every node in the cluster.
6. On any node other than the node you are deleting, run the following command
from the Grid_home/oui/bin directory where remaining_nodes_list is a
comma-delimited list of the nodes that are going to remain part of your cluster:
$ ./runInstaller -updateNodeList ORACLE_HOME=Grid_home "CLUSTER_NODES={remaining_nodes_list}" CRS=TRUE -silent--add
1. Ensure that you have successfully installed Oracle Clusterware on at least one node in your cluster environment.
2. Verify the integrity of the cluster and node3:
$ cluvfy stage -pre nodeadd -n node3 [-fixup [-fixupdir fixup_dir]] [-verbose]
3. To extend the Grid Infrastructure home to the node3("CLUSTER_NEW_NODES={node3,node4,node5}" "CLUSTER_NEW_VIRTUAL_HOSTNAMES={node3-vip,node4-vip,node5-vip}")
Grid_home/oui/bin/addNode.sh directory on node1
If you are using Grid Naming Service (GNS), run the following command:
$ ./addNode.sh "CLUSTER_NEW_NODES={node3}"
If you are not using GNS, run the following command:
$ ./addNode.sh "CLUSTER_NEW_NODES={node3}" "CLUSTER_NEW_VIRTUAL_HOSTNAMES={node3-vip}"
Alternatively,
$ ./addNode.sh -responseFile file_name
$ vi file_name
RESPONSEFILE_VERSION=2.2.1.0.0
CLUSTER_NEW_NODES={node3}
CLUSTER_NEW_VIRTUAL_HOSTNAMES={node3-vip}
4. If you have an Oracle RAC or Oracle RAC One Node database configured on the
cluster and you have a local Oracle home, then do the following to extend the
Oracle database home to node3:
$ $Oracle_home/oui/bin/addNode.sh "CLUSTER_NEW_NODES={node3}"
$ $Oracle_home/root.sh script on node3 as root, where Oracle_home is the Oracle RAC home.
5. Run the Grid_home/root.sh script on the node3 as root and run the subsequent script, as instructed.
6. Run the following CVU command to check cluster integrity.
$ cluvfy stage -post nodeadd -n node3 [-verbose]遇到的問題：
