添加节点容易遇到的问题： $ ./addNode.sh "CLUSTER_NEW_NODES={rac2}" "CLUSTER_NEW_VIRTUAL_HOSTNAMES={rac2-vip}" 报错1： 出现如下报错： 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 但此三个文件在节点2上又都可以找到，文件大小以及权限属性都和一节点一样，怀疑跟节点2有关（节点2本来是属于集群的，根据删除RAC节点删除节点2后，然后再添加的，可能跟这个有关） 解决办法： 在节点1的grid用户的$ORACLE_HOME/crs/install/install.excl文件中，添加如下： javavm/admin/classes.bin lib/libserver11.a install/usm/Novell/SLES11/x86_64/2.6.32.12-0.7/xen/bin/oracleacfs.ko 不需要删除节点2上的grid目录，直接在节点1再跑一遍addnode.sh即可 报错2： 出现报错： PRKC-1025 : Failed to create a file under the filepath /opt because the filepath is not executable or writable java.lang.OutOfMemoryError 解决办法： Increase JRE_MEMORY_OPTIONS=" -mx1024m" or greater value in the oraparam.ini located in: $GRID_HOME/oui/ 参考文档：Addnode.sh or Fresh Install Fails With PRKC-1025 and Java.Lang.OutOfMemoryError (文档 ID 1085893.1) 报错3: 如果出现以下报错： 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").
