之前安装时出错了, 于是再次安装.但配置节点时报错,如下:
"The installer has detected the existence of 10g oracle clusterware on the remote node, node2, however, 10g Oracle Clusterware does not exist on the local node. If you wish to upgrade an existing 10g Release 2, then you must start the installer on a node local to the older 10g Oracle Clusterware installetion. If you want to create a new cluster, you must choose a set of nodes that are not part of an existing cluster".
解决方法是删除/etc/oracle/ocr.loc
