Orcle 12c 新特性---支持将OCR备份到磁盘组中

1 说明

从12c开始，支持将OCR备份到磁盘组中。将在Oracle ASM磁盘组中存储OCR备份可以简化OCR管理，如果需要OCR恢复，则允许在集群中的任何节点访问OCR备份。

2 实验

2.1 修改OCR备份路径

[root@rac1 ~]# /u01/app/12.2.0/grid/bin/ocrconfig -backuploc +DATA

2.2 手动备份一下

[root@rac1 ~]# /u01/app/12.2.0/grid/bin/ocrconfig -manualbackup
rac1     2017/08/11 15:27:36     +DATA:/rac/OCRBACKUP/backup_20170811_152736.ocr.281.951751657     0    

2.3 查看OCR备份信息

[root@rac1 ~]# /u01/app/12.2.0/grid/bin/ocrconfig -showbackup
rac1     2017/08/11 13:20:57     /u01/app/12.2.0/grid/cdata/rac/backup00.ocr     0
rac1     2017/08/11 13:20:57     /u01/app/12.2.0/grid/cdata/rac/day.ocr     0
rac1     2017/08/11 13:20:57     /u01/app/12.2.0/grid/cdata/rac/week.ocr     0
rac1     2017/08/11 15:27:36     +DATA:/rac/OCRBACKUP/backup_20170811_152736.ocr.281.951751657     0
