Oracle 10g下ocr和votedisk的管理

ocr和votedisk是什么？

作为集群，oracle cluster需要共享存储来存放整个集群的配置信息，ocr便是用例存放这些配置信息的地方，ocr的存储容量一般不会太大，在10g下，oracle建议256M已经足以。ocr必须需要存储在集群文件系统或者裸设备上，出于性能上的考虑，本人建议将ocr建立在裸设备上，性能高并且管理也不复杂（ocr和votedisk的数量一般不会太多）。ocr中存放的是集群的配置信息，这些信息只能在一个节点上进行维护操作，这一节点叫做Master
Node，其他节点会在内存中保留一份ocr的复制，并且只能进行读操作，所有ocr的更新都是有master node来执行并通知各个节点的。

votedisk磁盘存储集中地各个节点并用来进行心跳监测

ocr和votedisk的维护是否需要保持脱机状态？

orc的维护在大多数情况下，是需要联机操作的，因为在各个节点具有ocr.loc文件，联机操作可以保证各个节点的ocr.loc文件及时得到更新。但是部分操作，如repaire和重建等操作需要在脱机状态下进行（后面会详细描述）

votedisk磁盘的维护往往需要在脱机状态下进行

ocr维护的命令有哪些？

维护ocr常用的命令有：

ocrcheck

[[email protected] bin]# ./ocrcheck -h
Name:
	ocrcheck - Displays health of Oracle Cluster Registry.

Synopsis:
	ocrcheck 

Description:
	prompt> ocrcheck
	Displays current usage, location and health of the cluster registry

Notes:
	A log file will be created in
	$ORACLE_HOME/log/<hostname>/client/ocrcheck_<pid>.log. Please ensure
	you have file creation privileges in the above directory before
	running this tool.

ocrdump（dump出来的内容可以用来查看ocr中的内容，但是不可以用来进行恢复）

[[email protected] bin]# ./ocrdump -h
Name:
	ocrdump - Dump contents of Oracle Cluster Registry to a file.

Synopsis:
	ocrdump [<filename>|-stdout] [-backupfile <backupfilename>] [-keyname <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 -stdout -xml
	writes cluster registry contents to stdout in xml format

Notes:
	The header information will be retrieved based on best effort basis.
	A log file will be created in
	$ORACLE_HOME/log/<hostname>/client/ocrdump_<pid>.log. Make sure
	you have file creation privileges in the above directory before
	running this tool.

ocrconfig

[[email protected] bin]# ./ocrconfig -h
Name:
	ocrconfig - Configuration tool for Oracle Cluster Registry.

Synopsis:
	ocrconfig [option]
	option:
		-export <filename> [-s online]
		                                    - Export cluster register contents to a file
		-import <filename>                  - Import cluster registry contents from a file
		-upgrade [<user> [<group>]]
		                                    - Upgrade cluster registry from previous version
		-downgrade [-version <version string>]
		                                    - Downgrade cluster registry to the specified version
		-backuploc <dirname>                - Configure periodic backup location
		-showbackup                         - Show backup information
		-restore <filename>                 - Restore from physical backup
		-replace ocr|ocrmirror [<filename>] - Add/replace/remove a OCR device/file
		-overwrite                          - Overwrite OCR configuration on disk
		-repair ocr|ocrmirror <filename>    - Repair local OCR configuration
		-help                               - Print out this help information

Note:
	A log file will be created in
	$ORACLE_HOME/log/<hostname>/client/ocrconfig_<pid>.log. Please ensure
	you have file creation privileges in the above directory before
	running this tool.

Table D-1 The ocrconfig Command Options

Option Purpose

-backuploc
To change an OCR backup file location. For this entry, use a full path that is accessible by all of the nodes.

-downgrade
To downgrade an OCR to an earlier version.

-export
To export the contents of an OCR into a target file.

-help
To display help for the ocrconfig commands.

-import
To import the OCR contents from a previously exported OCR file.

-overwrite
To update an OCR configuration that is recorded on the OCR with the current OCR configuration information that is found on the node from which you are running this command.

-repair
To update an OCR configuration on the node from which you are running this command with the new configuration information specified by this command.

-replace
To add, replace, or remove an OCR location.

-restore
To restore an OCR from an automatically created OCR backup file.

-showbackup
To display the location, timestamp, and the originating node name of the backup files that Oracle created in the past 4 hours, 8 hours, 12 hours, and in the last day and week. You do not have to be the root user
to execute the -showbackup option.

-upgrade
To upgrade an OCR to a later version.

ocr损坏后怎么恢复？

ocr损坏后通常有两种方式进行修正：恢复和重建。恢复的时候，我们可以从之前export导出的文件恢复，也可以从之前有masternode备份的文件进行恢复。

具体的操作过程这里不再演示，

10g下怎么增加或者删除ocr磁盘？

在10g中，如果在安装cluster时，如果选择external  redundancy那么ocr只能选择一个磁盘，但是通过命令行我们依然可以添加新的磁盘到ocr。如果我们需要替换现有的ocr磁盘，那么必须同时存在两份ocr磁盘才可以，即primary ocr和mirror ocr同时存在时，才可以替换primary ocr或者mirror ocr。

操作实例：

新增或者删除orc最好在所有节点都在线时进行，否则会出现节点信息不同步的情况，

例如：如果在节点node2关闭时，在节点node1进行ocr删除操作，结果如下

结论：在增加、删除、替换ocr时，所有节点最好同时在线，在导入导出或者恢复ocr是，cluster节点需要关闭

如何添加/删除votedisk？

添加删除votedisk可以使用crsctl命令：

[[email protected] bin]# ./crsctl
Usage: crsctl check  crs          - checks the viability of the CRS stack
       crsctl check  cssd         - checks the viability of CSS
       crsctl check  crsd         - checks the viability of CRS
       crsctl check  evmd         - checks the viability of EVM
       crsctl set    css <parameter> <value> - sets a parameter override
       crsctl get    css <parameter> - gets the value of a CSS parameter
       crsctl unset  css <parameter> - sets CSS parameter to its default
       crsctl query  css votedisk    - lists the voting disks used by CSS
       crsctl add    css votedisk <path> - adds a new voting disk
       crsctl delete css votedisk <path> - removes a voting disk
       crsctl enable  crs    - enables startup for all CRS daemons
       crsctl disable crs    - disables startup for all CRS daemons
       crsctl start crs  - starts all CRS daemons.
       crsctl stop  crs  - stops all CRS daemons. Stops CRS resources in case of cluster.
       crsctl start resources  - starts CRS resources.
       crsctl stop resources  - stops  CRS resources.
       crsctl debug statedump evm  - dumps state info for evm objects
       crsctl debug statedump crs  - dumps state info for crs objects
       crsctl debug statedump css  - dumps state info for css objects
       crsctl debug log css [module:level]{,module:level} ...
                             - Turns on debugging for CSS
       crsctl debug log crs [module:level]{,module:level} ...
                             - Turns on debugging for CRS
       crsctl debug log evm [module:level]{,module:level} ...
                             - Turns on debugging for EVM
       crsctl debug log res <resname:level> turns on debugging for resources
       crsctl query crs softwareversion [<nodename>] - lists the version of CRS software installed
       crsctl query crs activeversion - lists the CRS software operating version
       crsctl lsmodules css - lists the CSS modules that can be used for debugging
       crsctl lsmodules crs - lists the CRS modules that can be used for debugging
       crsctl lsmodules evm - lists the EVM modules that can be used for debugging

 If necesary any of these commands can be run with additional tracing by
 adding a "trace" argument at the very front.
 Example: crsctl trace check css

首先在线添加：

[[email protected] bin]# ./crsctl add css votedisk /dev/raw/raw4
Cluster is not in a ready state for online disk addition
[[email protected] bin]# ./crsctl add css votedisk /dev/raw/raw4 -force
Now formatting voting disk: /dev/raw/raw4

删除操作不再演示

看来在线添加votedisk是可以成功的，在10g下需要使用 -force选项，但是网上有资料表示：在添加或者删除votedisk时，最好停掉所有应用。

如何重新创建ocr和votedisk（在ocr和votedisk损坏，并且没有备份时，这是非常有用的）？

首先，在所有的节点停止cluster

[[email protected] ~]# ocrcheck
Status of Oracle Cluster Registry is as follows :

在每个节点执行rootdelete.sh脚本

从上面可以看出，crs已经正常运行，但是vip one gns等资源没有配置成功（可能是因为执行我修改过ip的原因），手工调用vipca图形界面后：

[[email protected] ~]# crs_stat -t -v

ora.node2.vip  application    0/0    0/0    ONLINE    ONLINE    node2

添加剩余资源到rac中，如asm，instance，linstener

调用netca添加listener，使用srvctl添加其他服务，至此重建ocr和votedisk完成

有一点需要注意，ocr和votedisk重建后，ocr磁盘和votedisk磁盘会设置为cluster新建时的初始值，如何后续我们对此进行过修改，则需要我们手工来进行再次维护了
