Oracle 11g RAC中，发现oc4j以及gsd服务都处于offline状态，这是Oracle 11g RAC默认情形。即便如此，并不影响数据库的使用，因为 oc4j 是用于WLM 的一个资源, WLM在 11.2.0.2 才可用。GSD则是用于支持dbca,srvctl,oem等的交互工具。本文描述将这两个服务切换到online。
1、环境
[root@linux2 ~]# cat /etc/issue
Enterprise Linux Enterprise Linux Server release 5.5 (Carthage)
Kernel \r on an \m
[root@linux2 bin]# ./crsctl query crs activeversion
Oracle Clusterware active version on the cluster is [11.2.0.1.0]
2、oc4j与所有的gsd处于offline
[grid@linux2 ~]$ crs_stat -t | grep OFFLINE
ora.gsd ora.gsd.type OFFLINE OFFLINE
ora.linux1.gsd application OFFLINE OFFLINE
ora.linux2.gsd application OFFLINE OFFLINE
ora.oc4j ora.oc4j.type OFFLINE OFFLINE
3、启动oc4j服务
#使用srvctl 来启动oc4j服务
[grid@linux2 ~]$ srvctl start oc4j
OC4J could not be started
PRCR-1079 : Failed to start resource ora.oc4j
CRS-2501: Resource 'ora.oc4j' is disabled #提示该服务处于disable状态
#尝试使用crsctl来启动，依然失败
[grid@linux2 ~]$ crsctl start res ora.oc4j -init
CRS-2613: Could not find resource 'ora.oc4j'.
CRS-4000: Command Start failed, or completed with errors.
#下面先将状态置为enable状态
[grid@linux2 ~]$ srvctl enable oc4j
#再次启动成功
[grid@linux2 ~]$ srvctl start oc4j
[grid@linux2 ~]$ crs_stat -t | grep oc4j
ora.oc4j ora.oc4j.type ONLINE ONLINE linux2
4、启动gsd服务
#查看节点linux1上所有的资源状态，可以看到输出的信息表明GSD也被disable了
[grid@linux2 ~]$ srvctl status nodeapps -n linux1
-n <node_name> option has been deprecated.
VIP linux1-vip is enabled
VIP linux1-vip is running on node: linux1
Network is enabled
Network is running on node: linux1
GSD is disabled
GSD is not running on node: linux1
ONS is enabled
ONS daemon is running on node: linux1
eONS is enabled
eONS daemon is running on node: linux1
#下面查看节点linux2上所有的资源状态，也可以看到输出的信息表明GSD也被disable了
[grid@linux2 ~]$ srvctl status nodeapps -n linux2
-n <node_name> option has been deprecated.
VIP linux2-vip is enabled
VIP linux2-vip is running on node: linux2
