oracle11gRAC的oc4j和gsd服务都处于offline状态

--------------------------------------------------------------------------------

Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 -

64bit Production

PL/SQL Release 11.2.0.4.0 - Production

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，为了向后兼容9i而保留。

本文描述将这两个服务切换到online。

1、环境

[grid@jinhu-db02 ~]$ cat /etc/issue

CentOS release 6.9 (Final)

Kernel \r on an \m

[grid@jinhu-db02 ~]$ uname -a

Linux jinhu-db02 2.6.32-696.el6.x86_64 #1 SMP Tue Mar 21

19:29:05 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

2、oc4j与所有的gsd处于offline

oc4j与所有的gsd处于offline

[grid@jinhu-db02 ~]$ crs_stat -t | grep OFFLINE

ora.gsd ora.gsd.type OFFLINE OFFLINE

ora....b01.gsd application OFFLINE OFFLINE

ora....b02.gsd application OFFLINE OFFLINE

###如果没有9i的RAC数据库，不用启用GSD

Enable GSD in 11.2

srvctl enable nodeapps -g

srvctl start nodeapps

Disable GSD (11.2)

You may want to disable GSD after you upgraded all your

Oracle9i RAC databases.

srvctl stop nodeapps

srvctl disable nodeapps -g

srvctl start nodeapps

经验证，这里的disable的一系列操作，可以让ora.gsd的target本来是ONLINE变成OFFLINE.

oracle 11g的ora.gsd默认是OFFLINE

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@jinhu-db01 ~]$ srvctl status nodeapps -n

#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

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。

!!The End!!
