ORACLE 10.2.0.5 RAC升级到11.2.0.3 (一) 集群软件升级
ORACLE 10.2.0.5 RAC升级到11.2.0.3 (三)DATABASE升级
在Oracle 10g RAC的环境下,我们的OCR和VOTEING DISK都是放在裸设备里面的,升级到Oracle 11g RAC后,ORACLE默认采用了以前的方式,把OCR和VOTEING DISK放在裸盘上.不过我们新安装的ORACLE 11g RAC环境都是采用ASM来存放的.本章节主要是介绍把OCR和VOTEING DISK从裸设备迁移到ASM中.在迁移之前,我们先用ASMCA做一个新的OCR卷组出来.
划完卷组之后,我们就可以开始我们的迁移工作了.
1.迁移OCR到ASM
[root@rac1 bin]# ./ocrconfig -add +ocr [root@rac1 bin]# ./ocrconfig -delete /dev/raw/raw1 [oracle@rac1 ~]$ ocrcheck Status of Oracle Cluster Registry is as follows : Version : 3 Total space (kbytes) : 517828 Used space (kbytes) : 6236 Available space (kbytes) : 511592 ID : 1423844012 Device/File Name : +ocr Device/File integrity check succeeded Device/File not configured Device/File not configured Device/File not configured Device/File not configured Cluster registry integrity check succeeded Logical corruption check bypassed due to non-privileged user
2.迁移VOTEING DISK到ASM
[oracle@rac1 ~]$ crsctl replace votedisk +ocr CRS-4256: Updating the profile Successful addition of voting disk 4d0798b6cd214fb1bf8b201b69497a20. Successful deletion of voting disk 24837164cd2aef11ff7dfe4c65ee3ba9. Successfully replaced voting disk group with +ocr. CRS-4256: Updating the profile CRS-4266: Voting file(s) successfully replaced [oracle@rac1 ~]$ crsctl query css votedisk ## STATE File Universal Id File Name Disk group -- ----- ----------------- --------- --------- 1. ONLINE 4d0798b6cd214fb1bf8b201b69497a20 (/dev/raw/raw6) [OCR] Located 1 voting disk(s).
至此,我们已经把裸设备上的OCR和VOTEING DISK迁移到了ASM中,接下来就是最后升级DataBase.
