11g RAC 磁盘组迁移Normal到external(ASMLIB)

一、环境介绍

操作系统:Red Hat Enterprise Linux Server release 6.4 (Santiago)

数据库:Oracle 11.2.0.4.0 - 64bit Production(grid和oracle软件版本一致)

RAC实例名称:RACDB

现有磁盘组:

备注:原有磁盘组(OCR、DATA、FRA)都是Normal方式

添加磁盘组DGOCR、DGDATA、DGFRA以External方式(ASMLIB方式)

Disk /dev/sdc: 69.8 GB, 69793218560 bytes

255 heads, 63 sectors/track, 8485 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Sector size (logical/physical): 512 bytes / 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes

Disk identifier: 0xffdbacb6

   Device Boot      Start         End      Blocks   Id  System

/dev/sdc1               1        2612    20980858+  83  Linux

/dev/sdc2            2613        5224    20980890   83  Linux

/dev/sdc3            5225        7836    20980890   83  Linux

创建ASMLIB磁盘

[root@host03 oracle]# cat initdisk8.sh

## Delete asmdisk on host03

/etc/init.d/oracleasm deletedisk asmdisk8p1

/etc/init.d/oracleasm deletedisk asmdisk8p2

/etc/init.d/oracleasm deletedisk asmdisk8p3

## Create disk asmdisk on host03

/etc/init.d/oracleasm createdisk asmdisk8p1 /dev/sdc1

/etc/init.d/oracleasm createdisk asmdisk8p2 /dev/sdc2

/etc/init.d/oracleasm createdisk asmdisk8p3 /dev/sdc3

## Scan disk asmdisk on host03

/etc/init.d/oracleasm scandisks

/etc/init.d/oracleasm listdisks

## Scan disk asmdisk on host04

ssh host04 /etc/init.d/oracleasm scandisks

ssh host04 /etc/init.d/oracleasm listdisks

查看磁盘(host03、host04)

[root@host03 oracle]# ll /dev/oracleasm/disks/

二、目标换磁盘组将原来Normal 变成External方式

1、备份现有库

run{

allocate channel c1 device type disk;

allocate channel c2 device type disk;

allocate channel c3 device type disk;

sql 'alter system switch logfile';

backup as compressed backupset format '/home/oracle/backup/full_%U_%d.bak' database plus archivelog format '/home/oracle/backup/archive_%U_%d';

backup current controlfile format '/home/oracle/backup/controlfile_%U_%d.bak';

backup spfile  format '/home/oracle/backup/spfile_%U_%d.bak';

release channel c1;

release channel c2;

release channel c3;

}

2、备份OCR、VOTING、ASM spfile文件

镜像OCR配置:

[root@host03 bin]# ./ocrcheck

Status of Oracle Cluster Registry is as follows :

         Version                  :          3

         Total space (kbytes)     :     262120

         Used space (kbytes)      :       3268

         Available space (kbytes) :     258852

添加镜像OCR

[root@host03 bin]# ./ocrconfig -add +DGOCR

[root@host03 bin]# ./ocrcheck

         Available space (kbytes) :     258852

         ID                       : 1185425206

         Device/File Name         :       +OCR

                                    Device/File integrity check succeeded

         Device/File Name         :       +FRA

                                    Device/File integrity check succeeded

         Device/File Name         :     +DGOCR

                                    Device/File not configured

                                    Device/File not configured

         Cluster registry integrity check succeeded

         Logical corruption check succeeded

删除ocr信息在+FRA、+OCR

[root@host03 bin]# ./ocrconfig -delete  +OCR

[root@host03 bin]# ./ocrconfig -delete  +FRA

查看OCR信息

[root@host03 bin]# ./ocrconfig -add +DGFRA

SPFILE='+DGDATA/racdb/spfileracdb.ora'

[oracle@host04 dbs]$ vi initRACDB1.ora

SPFILE='+DGDATA/racdb/spfileracdb.ora'

修改OCR中spfile位置

srvctl modify database -d racdb -p '+DGDATA/racdb/spfileracdb.ora'

[oracle@host03 dbs]$ srvctl config database -d racdb
