Oracle Real Application Cluster 管理命令详解
参考《Real Application Clusters Administration and Deployment Guide》
Oracle Clusterware的命令集可以分为以下4种：
节点层：olsnodes
网络层：oifcfg
集群层：crsctl, ocrcheck,ocrdump,ocrconfig
应用层：srvctl,onsctl,crs_stat
下面分别来介绍这些命令
1. 节点层
olsnodes --- 显示集群点列表
[grid@rac1 root]$ olsnodes --help
Usage: olsnodes [ [ [-n] [-i] [-s] [-t] [ | -l [-p]] [-a] ] | [-f] | [-c] ] [-g] [-v]
where
-n print node number with the node name
-p print private interconnect address for the local node
-i print virtual IP name or address with the node name
print information for the specified node
-l print information for the local node
-s print node status - active or inactive
-t print node type - pinned or unpinned
-g turn on logging
-v Run in debug mode; use at direction of Oracle Support only.
-c print clusterware name
-a print active node roles of the nodes in the cluster
-f print historical Leaf Nodes (active and recent) 
2. 网络层
oifcfg ---
[grid@rac1 ~]$ oifcfg --help
PRIF-9: incorrect usage
Name:
oifcfg - Oracle Interface Configuration Tool.
Usage:
oifcfg iflist [-p] [-n] [-hdr]
Lists the network interfaces known to the operating system on this node that can be configured with 'oifcfg setif'.
-p displays a heuristic assumption of the interface type (PRIVATE, PUBLIC, or UNKNOWN).
-n displays the netmask.
-hdr displays column headings.
oifcfg setif {-node | -global} [/:[,...]][,...]
'oifcfg setif -global' or 'oifcfg setif -node ' is used to synchronize the interface details in the GPnP profile and OCR.
oifcfg getif [-node | -global] [ -if [/] [-type ]] [-hdr]
oifcfg delif {{-node | -global} [[/]] [-force] | -force}
oifcfg [-help]
- name of the host, as known to a communications network
- name by which the interface is configured in the system
- subnet address of the interface
- one or more comma-separated interface types { cluster_interconnect | public | asm}
oifctg命令用来定义和修改Oracle集群需要的网卡属性，这些属性包括网卡的网段地址，子网掩码，接口类型等。要想正确的使用这个命令，必须先知道Oracle是如何定义网络接口的，Oracle的每个网络接口包括名称，网段地址，接口类型3个属性：interface_name、subnet、interface_type。
这些属性中没有IP地址，但接口类型有两种，public和private，前者说明接口用于外部通信，用于Oracle Net和VIP地址，而后者说明接口用于Interconnect。
接口的配置方式分为两类：
global和node-specific。前者说明集群所有节点的配置信息相同，也就是说所有节点的配置是对称的；而后者意味着这个节点的配置和其他节点配置不同，是非对称的。
Iflist：显示网口列表
getif：获得单个网口信息
setif：配置单个网口
delif：删除网口
3. 集群层
集群层是指由Clusterware组成的核心集群， 这一层负责维护集群内的共享设备，并为应用集群提供完整的集群状态视图，应用集群依据这个视图进行调整。这一层共有4个命令：crsctl、ocrcheck、ocrdump、ocrconfig，后三个是针对OCR磁盘的。
3.1 crsctl
crsctl命令可以用来检查crs进程栈，每个crs进程状态，管理Votedisk，跟踪crs进程功能。
crsctl3.1.1 检查crs状态
crsctl check crs
crsctl check cssd
crsctl check crsd
crsctl check evmd
crsctl check cluster -all 
3.1.2 配置crs自启动
CRS进程栈默认随着操作系统的启动而自启动，有时出于维护目的需要关闭这个特性，可以用root用户执行下面命令。
crsctl disable crs
crsctl enable crs
此命令修改/etc/oracle/scls_scr/rac1/root/crsstart中的配置，但此次配置之后crsstart中的内容并未更改。待深入研究

尝试增加一块votingdisk
--- 查看votingdisk状态
[root@rac1 bin]# ./crsctl query css votedisk
--- 停止所有节点的CRS服务：
[root@rac1 bin]# ./crsctl stop crs
--- 添加Votingdisk
[root@rac1 bin]# ./crsctl add css votedisk /dev/asmdisk07 -force
注意：即使在CRS关闭后，也必须通过-force参数来添加和删除Votedisk，并且-force参数只有在CRS关闭的场合下使用才安全，否则会报：Cluter is not a ready state for online disk addition.
--- 确认添加后的状态：
[root@rac1 bin]# ./crsctl query css votedisk
--- 启动CRS服务
[root@rac1 bin]# ./crsctl start crs注：添加和删除Votedisk的操作非常危险，必须停止数据库，停止ASM，停止CRS 后操作，并且操作时必须使用-force参数
3.2 ocrcheck、ocrdump、ocrconfig
Oracle Clusterware把整个集群的配置信息放在共享存储上，这个存储就是OCR Disk.在整个集群中，只有一个节点能对OCR Disk进行读写操作，这个节点叫作Master Node，所有节点都会在内存中保留一份OCR的拷贝，同时有一个OCR Process从这个内存中读取内容。OCR内容发生改变时，由Master Node的OCR Process负责同步到其他节点的OCR Process。
OCR的内容如此重要，Oracle每4个小时对其做一次备份，并且保留最后的3个备份，以及前一天，前一周的最后一个备份。这个备份由Master Node CRSD进程完成，备份的默认位置是$CRS_HOME\crs\cdata\
3.2.1 ocrdump
该命令能以ASCII的方式打印出OCR的内容，但不能用作OCR的备份，产生的文件只能用作阅读，而不能用于恢复
[grid@rac1 ~]$ ocrdump --help
Name:
ocrdump - Dump contents of Oracle Cluster/Local Registry to a file.
Synopsis:
ocrdump [-local] [|-stdout] [-backupfile ] [-keyname ] [-xml] [-noheader]
Description:
Default filename is OCRDUMPFILE. Examples are:
prompt> ocrdump
writes cluster registry contents to OCRDUMPFILE in the current directory
prompt> ocrdump MYFILE
writes cluster registry contents to MYFILE in the current directory
prompt> ocrdump -stdout -keyname SYSTEM
writes the subtree of SYSTEM in the cluster registry to stdout
prompt> ocrdump -local -stdout -xml
writes local registry contents to stdout in xml format
prompt> ocrdump -backupfile /oracle/CRSHOME/backup.ocr -stdout -xml
writes registry contents in the backup file to stdout in xml format
Notes:
* The header information will be retrieved based on best effort basis.
* Use option '-local' to indicate that the operation is to be performed on the Oracle Local Registry.
3.2.2 ocrcheck
ocrcheck命令用于检查OCR内容的一致性，这个命令不需要参数。
[grid@rac1 ~]$ ocrcheck --help
Name:
ocrcheck - Displays health of Oracle Cluster/Local Registry.
Synopsis:
ocrcheck [-config | -backupfile ] [-details] [-local]
-config Displays the configured locations of the Oracle Cluster Registry.
This can be used with the -local option to display the configured
location of the Oracle Local Registry
-details Displays detailed configuration information.
-local The operation will be performed on the Oracle Local Registry.
-backupfile The operation will be performed on the backup file.
Notes:
* This command for Oracle Cluster Registry is not supported from a Leaf node.
3.2.3 ocrconfig
该命令用于维护OCR磁盘，安装clusterware过程中，如果选择External Redundancy冗余方式，则只能输入一个OCR磁盘位置。但是Oracle允许配置两个OCR磁盘互为镜像，以防止OCR磁盘的单点故障。OCR磁盘和Votedisk磁盘不一样，OCR磁盘最多只能有两个，一个Primary OCR和一个Mirror OCR
[grid@rac1 ~]$ ocrconfig --help
Name:
ocrconfig - Configuration tool for Oracle Cluster/Local Registry.
Synopsis:

-help - Print out this help information
Notes:
* Use option '-local' to indicate that the operation is to be performed on the Oracle Local Registry.
查看OCR备份状态
3.2.4 OCR备份与恢复
Oracle推荐在对集群做调整时，比如增加，删除节点之前，应该对OCR做一个备份，可以使用export备份到指定文件，如果做了replace或者restore等操作，Oracle建议使用cluvfy comp ocr -n all命令来做一次全面的检查。cluvfy命令在clusterware的安装目录
--- 关闭所有节点的CRS
[root@rac1 bin]# /app/product/19.2.0/crs/bin/crsctl stop crs
--- 导出OCR内容
[root@rac1 bin]# /app/product/19.2.0/crs/bin/ocrconfig -export /app/ocr.exp
--- 启动CRS
[root@rac1 bin]# /app/product/19.2.0/crs/bin/crsctl start crs
--- 检查CRS状态
[root@rac1 bin]# /app/product/19.2.0/crs/bin/crsctl check crs
CSS appears healthy
CRS appears healthy
EVM appears healthy
--- 模拟OCR损坏
[root@rac1 bin]# dd if=/dev/zero f=/dev/asmdisk01 bs=1024 count=102400
102400+0 records in
102400+0 records out
--- 检查OCR一致性
[root@rac1 bin]# /app/product/19.2.0/crs/bin/ocrcheck
PROT-601: Failed to initialize ocrcheck
--- 使用cluvfy工具检查一致性
[root@rac1 cluvfy]# /app/product/19.2.0/crs/bin/runcluvfy.sh comp ocr -n all
Verifying OCR integrity
Unable to retrieve nodelist from Oracle clusterware.
Verification cannot proceed.
--- 使用Import恢复OCR内容
[root@rac1 bin]# /app/product/19.2.0/crs/bin/ocrconfig -import /app/ocr.exp
--- 再次检查OCR一致性
[root@rac1 bin]# /app/product/19.2.0/crs/bin/ocrcheck
--- 再次使用cluvfy工具检查一致性
[root@rac1 cluvfy]# /app/product/19.2.0/crs/bin/runcluvfy.sh comp ocr -n all3.2.5 迁移OCR磁盘
实验演示将OCR从/dev/asmdisk01 迁移至/dev/asmdisk08
--- 查看OCR备份
[root@rac1 bin]# /app/product/19.2.0/crs/bin/ocrconfig -showbackup
如果没有备份，立即执行一次导出作为备份：
[root@rac1 bin]# /app/product/19.2.0/crs/bin/ocrconfig -export /u01/ocrbackup -s online
--- 查看OCR配置
[root@rac1 bin]# /app/product/19.2.0/crs/bin/ocrcheck
--- 添加一个Mirror OCR
[root@rac1 bin]# /app/product/19.2.0/crs/bin/ocrconfig -replace ocrmirror /dev/asmdisk08
--- 确认添加成功
[root@rac1 bin]# /app/product/19.2.0/crs/bin/ocrcheck
--- 改变primary OCR位置
[root@rac1 bin]# /app/product/19.2.0/crs/bin/ocrconfig -replace ocr /dev/asmdisk08
确认修改成功：
[root@rac1 bin]# /app/product/19.2.0/crs/bin/ocrcheck
--- 使用ocrconfig命令修改后，所有RAC节点上的/etc/oracle/ocr.loc文件内容也会自动同步了，如果没有自动同步，可以手工的改成以下内容。
[root@rac1 bin]#more /etc/oracle/ocr.loc
ocrconfig_loc=/dev/asmdisk01
ocrmirrorconfig_loc=/dev/asmdisk08
local_only=FALSE4 应用层
应用层就是指RAC数据库了，这一层有若干资源组成，每个资源都是一个进程或者一组进程组成的完整服务，这一层的管理和维护都是围绕这些资源进行的。有如下命令:srvctl, onsctl, crs_stat三个命令
4.1 crs_stat
crs_stat这个命令用于查看CRS维护的所有资源的运行状态，如果不带任何参数时，显示所有资源的概要信息。每个资源显示是各个属性：资源名称，类型，目录，资源运行状态等。18c之后此命令已不再被支持
crs_stat -t
crs_stat -ls4.2 onsctl
这个命令用于管理配置ONS(Oracle Notification Service). ONS是Oracle Clusterware实现FAN Event Push模型的基础。在传统模型中，客户端需要定期检查服务器来判断服务端状态，本质上是一个pull模型，Oracle 10g引入了一个全新的PUSH机制–FAN(Fast Application Notification),当服务端发生某些事件时，服务器会主动的通知客户端这种变化，这样客户端就能尽早得知服务端的变化。而引入这种机制就是依赖ONS实现， 在使用onsctl命令之前，需要先配置ONS服务
[grid@rac1 bin]$ onsctl
usage: onsctl [verbose] []
The verbose option enables debug tracing and logging (for the server start).
Permitted / combinations are:
command options
------- ---------
start - Start ons
shutdown - Shutdown ons
reload - Trigger ons to reread its configuration file
debug [= ..] - Display ons server debug information
set [= ..] - Set ons log parameters
query [=] - Query ons log parameters
ping [] - Ping local ons
help - Print brief usage description (this)
usage [] - Print detailed usage description
--- example
--- 查看进程状态
[root@rac1 bin]#ps -aef|grep ons
--- 查看ONS服务的状态
[root@rac1 bin]# /app/product/19.2.0/crs/bin/onsctl ping
--- 启动ONS服务
[root@rac1 bin]# /app/product/19.2.0/crs/bin/onsctl start
--- 使用debug选项，可以查看详细信息，其中最有意义的就是能显示所有连接
[root@rac1 bin]# /app/product/19.2.0/crs/bin/onsctl debug
ONS状态检查
4.3 srvctl
该命令是RAC维护中最常用的命令，也是最复杂的命令。 这个工具可以操作下面的几种资源：Database，Instance，ASM，Service，Listener和Node Application，其中Node application又包括GSD，ONS，VIP。 这些资源除了使用srvctl工具统一管理外，某些资源还有自己独立的管理工具，比如ONS可以使用onsctl命令进行管理、Listener可以通过lsnrctl管理
