Starting with Oracle Database 12c, we can store the ASM and Database password file on ASM storage. This is helpful for RAC databases and cluster as we do not have to manage to keep the files in sync between servers.
ASMCMD in 12c includes several commands to manage password file.
| pwcopy | Copies a password file to the specified location. |
| pwcreate | Creates a password file at the specified location. |
| pwdelete | Deletes a password file at the specified location. |
| pwget | Returns the location of the password file. |
| pwmove | Moves the location of the password file. |
| pwset | Sets the location of the password file. |
| lspwusr | Lists the users from an Oracle ASM password file. |
| orapwusr | Adds, drops, or changes an Oracle ASM password user. |
These commands can manage the Grid Infrastructure ASM password file or the Database password file. Specify the type of instance using the parameters:
--asm |
The --asm option associates the password file with the Oracle ASM instance that ASMCMD is logged into. |
--dbuniquename string |
The --dbuniquename string option identifies the database unique name associated with the password file. |
