数据库技术:Oracle11gR2RACwithASM存储迁移–Rmancopy&ASMRebalance(一)

ASMGROUP-Rmancopy迁移0x00--环境介绍VMware版本:VMware12pro主机操作系统:RHEL6.5_64共享存储使用VMWARE创建共享磁盘文件数据库版

ASM GROUP-Rman copy迁移

0x00–环境介绍

VMware版本:VMware12pro

主机操作系统:RHEL6.5_64

共享存储使用VMWARE创建共享磁盘文件

数据库版本:Oracle11gR2 11.2.0.4.0_RAC

Oracle数据库文件部署在ASM磁盘组上,需要在不停机或者尽量短的停机时间完成存储迁移。由于只是设计存储更换,无需借助第三方工具。采取迁移ASM DISKGROUP的方式完成迁移。模拟现实环境中,ASM磁盘组存放在存储设备上,模拟由于设备升级、存储虚拟化整合或者存储设备淘汰,需要进行存储更换。

首先使用新建ASM GROUP,使用rman copy替换旧有的存储ASM group,然后再采取ASM Rebalance进行在线迁移回来。两种方法

0x01–迁移步骤

数据为重,首先应该有完整可恢复的数据备份,确保数据的安全性。再进行迁移。迁移前首先收集数据库现有的信息。

1)      划分asm disk,并检查或更改UDEV配置文件,使得新存储的asm disk对ASM实例可识别。  2)      备份OCR、Voting Disk、ASM disk header和数据库。  3)      创建新的DISKGROUP  4)      迁移OCR和Vote Disks到新磁盘组(ASM diskgroup)  5)      迁移ASM Spfile到新磁盘组(ASM diskgroup)  6)      迁移数据库相关文件至新磁盘组(ASM diskgroup)  7)      在线修改数据库参数文件(归档路径、闪回等)  8)      删除旧磁盘组  9)      观察期。  10)   执行数据库备份

0x02–新存储划分空间

模拟环境中,是用VMware创建共享磁盘文件实现新存储划分。新创建3个10G新共享存储磁盘,ndata1,ndata2,ndata3用于存放数据文件,新建3个1GB共享存储磁盘,nocr1,nocr2,nocr3,用于存放OCR与VOTE信息,将原存储上的数据全部迁移过来。
