今天看著我這個單節點的12C rac,突然覺得ocr所在的磁碟組叫做+DG_SYS有點不舒服，想改成+SYS_DG。處理方法是先把ocr/votedisk/asm spfile遷移到已經存在的asm中,然後修改磁碟組名稱,最後遷移到新名稱磁碟組中(本次處理流程+DG_SYS—>+DATA—>+SYS_DG)

這裡證明create asm spfile會自動修改spfile在gpnptool對應的profile裡面的配置,無需人工干預
重啟crs
為了使得asm使用新的磁碟組中的spfile檔案
[root@xifenfei ~]# crsctl stop crs
[root@xifenfei ~]# crsctl start crs

驗證+DG_SYS磁碟組未被使用

至此ocr/votedisk/asm spfile所在磁碟組修改名稱完成,因為該庫是一個單節點的rac,如果是兩個或者更多節點的rac可以實現不停機的情況下進行(分步重啟節點).該處理過程和11.2 rac完全相同,未有任何的改變
- ORACLE 12C RAC hub AND leaf 相互轉換
- oracle 12.1 RAC的ocr磁碟組異常恢復
- OCR/Vote disk 維護操作
- 安裝 ORACLE 12C 單節點RAC
- has a disk HB, but no network HB—-traceroute不通導致
- crfclust.bdb檔案過大處理
- 公有云安裝19c rac遇到問題—169網段udp異常
- oracle rac 12.2 執行root.sh報CLSRSC-400
- 修改11.2 RAC 的 SCAN IP
- 一次 CRS-1013: ASM 磁碟組中的 OCR 位置不可訪問 故障分析
- RAC維護命令
- 因asm sga_target設定不當導致11gr2 rac無法正常啟動
