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. 1、环境
2. [root@linux2 ~]# cat /etc/issue
3. Enterprise Linux Enterprise Linux Server release 5.5 (Carthage)
4. Kernel \r on an \m
5.
6. [root@linux2 bin]# ./crsctl query crs activeversion
7. Oracle Clusterware active version on the cluster is [11.2.0.1.0]
8.
9. 2、oc4j与所有的gsd处于offline
10. [grid@linux2 ~]$ crs_stat -t | grep OFFLINE
11. ora.gsd ora.gsd.type OFFLINE OFFLINE
12. ora.linux1.gsd application OFFLINE OFFLINE
13. ora.linux2.gsd application OFFLINE OFFLINE
14. ora.oc4j ora.oc4j.type OFFLINE OFFLINE
15.
16. 3、启动oc4j服务
17. #使用srvctl 来启动oc4j服务
18. [grid@linux2 ~]$ srvctl start oc4j
19. OC4J could not be started
20. PRCR-1079 : Failed to start resource ora.oc4j
21. CRS-2501: Resource 'ora.oc4j' is disabled #提示该服务处于disable状态
22.
23. #尝试使用crsctl来启动,依然失败
24. [grid@linux2 ~]$ crsctl start res ora.oc4j -init
25. CRS-2613: Could not find resource 'ora.oc4j'.
26. CRS-4000: Command Start failed, or completed with errors.
27.
28. #下面先将状态置为enable状态
29. [grid@linux2 ~]$ srvctl enable oc4j
30. #再次启动成功
31. [grid@linux2 ~]$ srvctl start oc4j
32. [grid@linux2 ~]$ crs_stat -t | grep oc4j

54. VIP linux2-vip is running on node: linux2
55. Network is enabled
56. Network is running on node: linux2
57. GSD is disabled

59. ONS is enabled
60. ONS daemon is running on node: linux2
61. eONS is enabled
62. eONS daemon is running on node: linux2
63.
64. #将所有的服务置于enable状态
65. [grid@linux2 ~]$ srvctl enable nodeapps
66. PRKO-2415 : VIP is already enabled on node(s): linux1,linux2
67. PRKO-2416 : Network resource is already enabled.
68. PRKO-2417 : ONS is already enabled on node(s): linux1,linux2
69. PRKO-2418 : eONS is already enabled on node(s): linux1,linux2
70.
71. #再次查看GSD的状态已经变成enable了
72. [grid@linux2 ~]$ srvctl status nodeapps
73. VIP linux1-vip is enabled
74. VIP linux1-vip is running on node: linux1
75. VIP linux2-vip is enabled
76. VIP linux2-vip is running on node: linux2
77. Network is enabled
78. Network is running on node: linux1
79. Network is running on node: linux2
80. GSD is enabled

92. ora.linux1.gsd application OFFLINE OFFLINE
93. ora.linux2.gsd application OFFLINE OFFLINE
94.
95. #启动GSD服务
96. [grid@linux2 ~]$ srvctl start nodeapps
97. PRKO-2421 : Network resource is already started on node(s): linux1,linux2

101. PRKO-2423 : eONS is already started on node(s): linux1,linux2
102.
103. #验证GSD服务
104. [grid@linux2 ~]$ crs_stat -t | grep OFFLINE

113. 5、关于GSD
114. The Global Services Daemon (GSD) runs on each node with one GSD process per node.
115. The GSD coordinates with the cluster manager to receive requests from clients such as the DBCA, EM,
116. and the SRVCTL utility to execute administrative job tasks such as instance startup or shutdown.
117. The GSD is not an Oracle instance background process and is therefore not started with the Oracle instance.
118. 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。
119. 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。
120. 一个GSD进程支持在一个节点的多个rac.gsd进程,位于$ORACLE_HOME/bin目录下。
121. 其log文件为$oracle_home /srvm/log/gsdaemon.log。
122.
123. 例如:
124. 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,
125. 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。
126.
127. 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
128. 在本地节点上执行该请求,然后把执行结果返回给SRVCTL会话。
