1   说明

在12c中，Oracle ASM通过将密码文件存储在磁盘组里面，这样方便管理。

2  实验

2.1   查看当前ASM密码文件

--节点1http://www.cndba.cn/Expect-le/article/2089

[grid@rac1 ~]$ srvctl config  asm -detail
ASM home: <CRS home>
Password file: +OCR_VOTING/orapwASM
ASM listener: LISTENER
ASM is enabled.
ASM is individually enabled on nodes:
ASM is individually disabled on nodes:
ASM instance count: 3
Cluster ASM listener: ASMNET1LSNR_ASM

--节点2

http://www.cndba.cn/Expect-le/article/2089http://www.cndba.cn/Expect-le/article/2089

[grid@rac2 ~]$ srvctl config  asm -detail
ASM home: <CRS home>
Password file: +OCR_VOTING/orapwASM
ASM listener: LISTENER
ASM is enabled.
ASM is individually enabled on nodes:
ASM is individually disabled on nodes:
ASM instance count: 3
Cluster ASM listener: ASMNET1LSNR_ASM

默认存储在OCR磁盘组中，可以通过手动修改密码文件所在磁盘组

2.2   修改密码文件位置

[root@rac1 ~]# /u01/app/12.2.0/grid/bin/srvctl modify asm -pwfile '+DATA/orapwASM'

[root@rac1 ~]# /u01/app/12.2.0/grid/bin/srvctl config asm
ASM home: <CRS home>
Password file: +DATA/orapwASM
ASM listener: LISTENER
ASM instance count: 3
Cluster ASM listener: ASMNET1LSNR_ASM

2.3   创建密码文件

--ASM 密码文件

orapwd file='+data/ASM/orapwasm' asm=y

--数据库密码文件

http://www.cndba.cn/Expect-le/article/2089

orapwd file='+data/ORCL/orapwdb' dbuniquename='cndba'

http://www.cndba.cn/Expect-le/article/2089http://www.cndba.cn/Expect-le/article/2089

--通过之前版本的密码文件，在磁盘组中创建新的密码文件http://www.cndba.cn/Expect-le/article/2089

http://www.cndba.cn/Expect-le/article/2089

orapwd input_file='/oraclegrid/dbs/orapwasm' file='+data/ASM/orapwasm' asm=y
