如何处理11gR2 RAC下oc4j和gsd服务为OFFLINE状态
在Oracle Enterprise Linux 5.5 X86_64位的机器上配置完11gR2 RAC后，grid用户执行crs_stat -t查看服务状态时，我们会看到有一些服务是OFFLINE状态，其中就包括ora.oc4j和ora.gsd这两类服务，具体状态，我们看下面的示例输出：

那么，是我们的RAC配置有问题吗?这两类服务没有ONLINE会不会影响RAC数据库呢？我们又该如何启动这些服务呢？
其实，我们的RAC配置是没有问题的，也不会影响数据库正常运行。在默认情况下，其中的ora.gsd服务状态是OFFLINE状态，我们可不予理会，除非需要在11g Cluster上配置Oracle 9iR2的RAC。但凡以grid用户执行crs_stat -t命令，看到Target和State这两列的状态均为OFFLINE，我们均可忽略。但是，我们该如何使之启动呢？
1 启动ora.oc4j服务：
