Oracle 11g RAC添加一节点过程

实验场景：

两节点RAC，主机名是db1、db2，现在需要添加db2。
本文是接上一文删除节点后的添加节点的过整过程。查看Oracle 11g R2 RAC删除一节点过程。
本例是在刚上删除节点过程后做的，如果是全新节点，需要按照Oracle 11g RAC安装过程配置环境变量等前期安装配置信息，全文全程采用字符界面方式操作，也可以采用图形界面进行。
本文假定相关例如网络通讯，用户，环境变量，存储都已经配置好，只需要安装GRID,Oracle的之前的过程。

1. 节点1上grid用户，检查节点2预环境检查

[[email protected] ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.0.6          db1
192.168.0.7          db2
192.168.0.8          db1-vip
192.168.0.9          db2-vip
10.10.10.10          db1-priv1
20.20.20.10          db1-priv2
10.10.10.20          db2-priv1
20.20.20.20          db2-priv2
192.168.0.10         scan-cluster

# su - grid
$ cluvfy stage -pre nodeadd -n db2 -fixup -fixupdir /tmp -verbose

过程略过，如果出现NTP,或/etc/resolv.conf可以根据实际环境情况忽略掉。
该步一定要做，了解服务器环境一些不合理的配置与安装环境，需要修改完成后，出现check passed
因为主机名修改了，两节点间grid用户信任关系需要重建，

2. oracle, grid用户等效性配置

等效性确认，一定要做的操作：

su - grid
date;ssh db1 date
date;ssh db2 date

su - oracle
date;ssh db1 date
date;ssh db2 date

如果等效性不能过，可以执行如下命令进行等效性操作：
/u01/app/11.2.0/grid/deinstall/sshUserSetup.sh -user grid -hosts db1 db2 -noPromptPassphrase
/u01/app/11.2.0/grid/deinstall/sshUserSetup.sh -user oracle -hosts db1 db2 -noPromptPassphrase

3. 在节点1 grid用户修改addNode.sh脚本

如果环境中有一个小问题会检查不通过，在图形界面安装时可以忽略的，这里是不能直接忽略的，需要修改一下addNode.sh文件

[[email protected] ~]$ vi $ORACLE_HOME/oui/bin/addNode.sh
#!/bin/sh
OHOME=/u01/app/11.2.0/grid
INVPTRLOC=$OHOME/oraInst.loc
EXIT_CODE=0
ADDNODE="$OHOME/oui/bin/runInstaller -addNode -invPtrLoc $INVPTRLOC ORACLE_HOME=$OHOME $*"
if [ "$IGNORE_PREADDNODE_CHECKS" = "Y" -o ! -f "$OHOME/cv/cvutl/check_nodeadd.pl" ]
then
        $ADDNODE
        EXIT_CODE=$?;
else
        CHECK_NODEADD="$OHOME/perl/bin/perl $OHOME/cv/cvutl/check_nodeadd.pl -pre ORACLE_HOME=$OHOME $*"
        $CHECK_NODEADD
        EXIT_CODE=$?;
EXIT_CODE=0 加入如下行
        if [ $EXIT_CODE -eq 0 ]
        then
                $ADDNODE
                EXIT_CODE=$?;
        fi
fi
exit $EXIT_CODE ;

4. db1节点上grid用户执行添加节点

# su - grid
$ $ORACLE_HOME/oui/bin/addNode.sh "CLUSTER_NEW_NODES={db2}" "CLUSTER_NEW_VIRTUAL_HOSTNAMES={db2-vip}"

7. 验证db2节点被添加

在保留的db1节点上：

（1）验证数据库是否已添加
