字号:T|T

概要:本文详细记录如何把运行在Windows 2K8环境上的Oracle 10gR2 双节点RAC数据库的OCR、Vote Disk以及存放在ASM磁盘组里的数据,迁移至新存储的步骤。

迁移之前的存储信息:

wps_clip_image-4627

如上图所示,我们的最终目标是要把OCR、Vote Disk,DATA、FLASH磁盘组从Disk 2,Disk 3上分别迁移至Disk 4和Disk 5。

接下来给出详细的操作步骤和流程:

1  迁移OCR

A 创建磁盘分区

C:\Users\Administrator>diskpart

Microsoft DiskPart version 6.1.7601

Copyright (C) 1999-2008 Microsoft Corporation.

On computer: HAMNODE1

DISKPART> list disk

Disk ###  Status         Size     Free     Dyn  Gpt

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

Disk 0    Online           40 GB      0 B

Disk 1    Online           20 GB    19 GB

Disk 2    Online         6149 MB  2048 KB

Disk 3    Online         6149 MB  2048 KB

Disk 4    Online         6149 MB  6147 MB

Disk 5    Online           10 GB    10 GB

DISKPART> select disk 4

Disk 4 is now the selected disk.

DISKPART> list part

There are no partitions on this disk to show.

DISKPART> create part ext

DiskPart succeeded in creating the specified partition.

DISKPART> create part log size=320

DiskPart succeeded in creating the specified partition.

DISKPART> create part log

DiskPart succeeded in creating the specified partition.

DISKPART> list part

Partition ###  Type              Size     Offset

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

Partition 0    Extended          6147 MB  1024 KB

Partition 1    Logical            320 MB  2048 KB

* Partition 2    Logical           5825 MB   323 MB

DISKPART>

分区之后:

wps_clip_image-12024

注:您应该在其他节点上看到同样的磁盘分区信息。且,建议在其他节点上将Windows系统自动给新分区分配的盘符移除掉。

B 准备磁盘,创建裸设备链接

C:\oracle\product\10.2.0\crs\BIN\GUIOracleOBJManager.exe

wps_clip_image-12115

wps_clip_image-24325

wps_clip_image-17645

wps_clip_image-13996

同样,执行完上述操作,您应该在RAC的所有节点上通过

C:\oracle\product\10.2.0\crs\BIN\GUIOracleOBJManager.exe程序看到相同的信息。

C 手工备份OCR

ocrconfig -export c:\oracle.....\backup_filename

备份之前,可以查看下OCR的自动备份信息:

c:\oracle\product\10.2.0\crs\BIN>ocrconfig -showbackup

hamnode2     2014/05/08 06:01:07     C:\oracle\product\10.2.0\crs\cdata\crs

hamnode2     2014/05/07 23:44:04     C:\oracle\product\10.2.0\crs\cdata\crs

hamnode2     2014/05/07 19:44:04     C:\oracle\product\10.2.0\crs\cdata\crs

hamnode2     2014/05/06 16:34:35     C:\oracle\product\10.2.0\crs\cdata\crs

hamnode1     2014/04/30 07:09:51     C:\oracle\product\10.2.0\crs\cdata\crs

c:\oracle\product\10.2.0\crs\BIN>

执行备份:

c:\oracle\product\10.2.0\crs\BIN>ocrconfig -export C:\oracle\product\10.2.0\crs\cdata\crs\backup_ocr_140508.bak

c:\oracle\product\10.2.0\crs\BIN>cd ..\cdata\crs

c:\oracle\product\10.2.0\crs\cdata\crs>dir

Volume in drive C has no label.

Volume Serial Number is BA2B-5F59

2 Dir(s)  20,506,509,312 bytes free

c:\oracle\product\10.2.0\crs\cdata\crs>

D 添加OCR镜像

ocrconfig -replace ocrmirror \\.\ocrmirror

添加之前,查看OCR信息:

c:\oracle\product\10.2.0\crs\BIN>ocrcheck

Status of Oracle Cluster Registry is as follows :

Version                  :          2

Total space (kbytes)     :     327452

Used space (kbytes)      :       3836

Available space (kbytes) :     323616

ID                       :  478679697

Device/File Name         : \\.\ocrcfg

Device/File integrity check succeeded

Device/File not configured

Cluster registry integrity check succeeded

c:\oracle\product\10.2.0\crs\BIN>

添加OCRMIRROR并验证:

c:\oracle\product\10.2.0\crs\BIN>ocrconfig -replace ocrmirror \\.\ocrmirror

c:\oracle\product\10.2.0\crs\BIN>ocrcheck

Status of Oracle Cluster Registry is as follows :

Version                  :          2

Total space (kbytes)     :     327452

Used space (kbytes)      :       3836

Available space (kbytes) :     323616

ID                       :  478679697

Device/File Name         : \\.\ocrcfg

Device/File integrity check succeeded

Device/File Name         : \\.\ocrmirror

Device/File integrity check succeeded

Cluster registry integrity check succeeded

c:\oracle\product\10.2.0\crs\BIN>

E 删除OCR device并验证

c:\oracle\product\10.2.0\crs\BIN>ocrconfig -replace ocr

c:\oracle\product\10.2.0\crs\BIN>ocrcheck

Status of Oracle Cluster Registry is as follows :

Version                  :          2

Total space (kbytes)     :     327452

Used space (kbytes)      :       3836

Available space (kbytes) :     323616

ID                       :  478679697

Device/File Name         : \\.\ocrmirror

Device/File integrity check succeeded

Device/File not configured

Cluster registry integrity check succeeded

c:\oracle\product\10.2.0\crs\BIN>

F 重启CRS并验证

至此,我们通过给OCR添加1份镜像然后删除原主OCR的方式,完成对OCR的迁移。

注:通过这种方式,删除原OCR之后,新添加的OCR镜像自动成为主OCR。

2 迁移Vote Disk

A 创建磁盘分区

这里的创建磁盘分区如创建OCR磁盘分区时,方法一致:

其他具体操作步骤类似。

5 删除磁盘分区

删除卷、磁盘分区信息之后:

wps_clip_image-19324

最终,对于OCR、Vote Disk的数据,我们分别通过添加镜像的方式,然后删除现有的配置,进而间接的将OCR、Vote Disk分别从Disk 2、Disk 3迁移到Disk 4和Disk 5。

对于存放在ASM 磁盘的DATA和FRA中的数据,我们是通过先对现有DATA、FRA 磁盘组分别添加ASM磁盘,然后删除磁盘组中原有的旧ASM磁盘,进而完成迁移ASM 磁盘数据的目标!

6 注意事项

1 Note:

Note:

You can migrate the RAC OCR when CRS is running ,but you cannot migrate the Voting Disk when the CRS is running.That means we must stop the CRS before we can migrate the Voting Disk.

2 Note:

Also,you must backup the voting disk when the CRS is running,or else if you shutdown the CRS first,and then you cannot use the ocopy command to backup the voting disk.

3 Note:

PROT-22: Storage too small

wps_clip_image-21036

Cause:

The ocrmirror disk space is less than the ocr disk space.

wps_clip_image-2601

Solution:

Enlarge the ocrmirror disk space as the same as the ocr disk space.

4 Note:

PROT-21: Invalid parameter

wps_clip_image-27194

Cause:

PROT-21 error is encountered because the cluster is not yet fully aware of the newly created logical drive that is being specified for <filename> in the ocrconfig -replace command.

Solution:[Doc ID 1059663.1]

This code defect is fixed in patch bundle 31 (and higher) for Oracle on Windows.
Patch 31 is available for download from My Oracle Support under the following patch numbers:

Microsoft Windows (32-bit) - 9233830
Microsoft Windows Itanium (64-bit) - 9233831
Microsoft Windows x64 (64-bit) - 9233832

There is also a relatively simple workaround available.  Namely, stop and restart the Oracle Object Service after creating the symbolic link for the new logical drive and before running the 'ocrconfig -replace' command.
