新增節點容易遇到的問題：
$ ./addNode.sh "CLUSTER_NEW_NODES={rac2}" "CLUSTER_NEW_VIRTUAL_HOSTNAMES={rac2-vip}"
報錯1：
出現如下報錯：
    PRCF-2022 : The file "/u01/11.2.0/grid/javavm/admin/classes.bin" became smaller while being transferred
    PRCF-2022 : The file "/u01/11.2.0/grid/lib/libserver11.a" became smaller while being transferred
    PRCF-2022 : The file "/u01/11.2.0/grid/install/usm/Novell/SLES11/x86_64/2.6.32.12-0.7/xen/bin/oracleacfs.ko" became smaller while being transferred
但此三個檔案在節點2上又都可以找到，檔案大小以及許可權屬性都和一節點一樣，懷疑跟節點2有關（節點2本來是屬於叢集的，根據刪除RAC節點刪除節點2後，然後再新增的，可能跟這個有關）
 
解決辦法：
在節點1的grid使用者的$ORACLE_HOME/crs/install/install.excl檔案中，新增如下：
javavm/admin/classes.bin
lib/libserver11.a
install/usm/Novell/SLES11/x86_64/2.6.32.12-0.7/xen/bin/oracleacfs.ko
不需要刪除節點2上的grid目錄，直接在節點1再跑一遍addnode.sh即可

PRKC-1025 : Failed to create a file under the filepath /opt because the filepath is not executable or writable

解決辦法：
Increase JRE_MEMORY_OPTIONS=" -mx1024m" or greater value in the oraparam.ini located in:  $GRID_HOME/oui/
參考文件：Addnode.sh or Fresh Install Fails With PRKC-1025 and Java.Lang.OutOfMemoryError (文件 ID 1085893.1)
 
報錯3:
如果出現以下報錯：
Performing tests to see whether nodes rac2,rac3 are available
.................SEVERE:OUI-35000: Fatal cluster error encountered (PRKN-1034 : Failed to retrieve IP address of host "rac2"). Correct the problem and try the operation again.
 
解決方案：
原因是由於inventory裡面有rac的資訊，根據實際根據更新inventory內容：
$ cd $ORACLE_HOME/oui/bin
$ ./runInstaller -updateNodeList ORACLE_HOME=<oracle_home_location> "CLUSTER_NODES={remaining_node_list}"   ---remaining_node_list表示所有其它節點

解決方案：
這裡是因為我在後面修改了rac2的NETMASK，雖然service network restart了，但是沒有在叢集裡做修改，所以報了這個錯，可以用下面的方法解決：
./srvctl modify nodeapps -n rac2 -A 10.0.0.101/255.255.255.0/eth0     ###public ip
./srvctl modify nodeapps -n rac2 -A 10.0.0.103/255.255.255.0/eth0     ###vip
修改完後，重啟叢集。

解決方案：
將db資源刪除重新新增節點即可</oracle_base></oracle_home_location>
