oc4j以及gsd服务都处于offline状态,这是Oracle 11g RAC默认情形



 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

5、关于GSD  
 The Global Services Daemon (GSD) runs on each node with one GSD process per node.   
 The GSD coordinates with the cluster manager to receive requests from clients such as the DBCA, EM,   
 and the SRVCTL utility to execute administrative job tasks such as instance startup or shutdown.   
 The GSD is not an Oracle instance background process and is therefore not started with the Oracle instance.   
 GSD与rac的管理工具dbca srvctl oem进行交互,用来完成实例的启动关闭等管理任务。   
 为了保证这些管理工具运行正常必须在所有的节点上先启动 gsd。  
 一个GSD进程支持在一个节点的多个rac.gsd进程,位于$ORACLE_HOME/bin目录下。  
 其log文件为$oracle_home /srvm/log/gsdaemon.log。  
   
 例如:   
 假设使用oem工具来启动一个实例,oem把该任务传递给相应的智能引擎,该智能引擎生成一个包含SRVCTL命令的脚本文件,  
 GSD进程读取该脚本文件并且执行该脚本,最后GSD把执行结果返回给智能引擎,近而智能引擎返回给OEM。  
   
 又例如假设使用srvctl工具关闭所有的实例,GSD进程接受来自SRVCTL工具发出的请求,并   
 在本地节点上执行该请求,然后把执行结果返回给SRVCTL会话。  


    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。
