本篇內容主要講解“RAC11G恢復OCR的方法是什么”，感興趣的朋友不妨來看看。本文介紹的方法操作簡單快捷，實用性強。下面就讓小編來帶大家學習“RAC11G恢復OCR的方法是什么”吧!
1.檢查ocr
|
[root@rac1 ~]# ocrcheck Status of Oracle Cluster Registry is as follows : Version : 3 Total space (kbytes) : 262120 Used space (kbytes) : 3232 Available space (kbytes) : 258888 ID : 811139123 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 succeeded |
2.檢查votedisk
|
[root@rac2 ~]# crsctl query css votedisk ## STATE File Universal Id File Name Disk group -- ----- ----------------- --------- --------- 1. ONLINE 4b031d63f88f4f0cbf5cc8688884d5f2 (/dev/asm-diskb) [OCR] 2. ONLINE 1acaf51067b94fcdbf62f9a4400050d2 (/dev/asm-diskc) [OCR] 3. ONLINE 8b7b21ad7d114f21bf5e703ec4ccc44e (/dev/asm-diskd) [OCR] Located 3 voting disk(s). |
3.導出ocr
|
[root@rac2 ~]# ocrconfig -export /tmp/ocr_20160202.dmp [root@rac2 ~]# ll tmp | grep 2016 ls: 無法訪問tmp: 沒有那個文件或目錄 [root@rac2 ~]# ll /tmp | grep 2016 -rw------- 1 root root 114426 2月 2 11:06 ocr_20160202.dmp |
4.查看備份
|
[root@rac2 ~]# ocrconfig -showbackup rac2 2016/02/01 17:30:53 /g01/11ggrid/app/11.2.3/grid/backup00.ocr rac2 2016/02/01 13:30:53 /g01/11ggrid/app/11.2.3/grid/backup01.ocr rac2 2016/02/01 09:30:52 /g01/11ggrid/app/11.2.3/grid/backup02.ocr rac2 2016/01/31 01:30:49 /g01/11ggrid/app/11.2.3/grid/day.ocr rac1 2016/01/26 20:52:17 /g01/11ggrid/app/11.2.3/grid/week.ocr PROT-25: Manual backups for the Oracle Cluster Registry are not available |
