This argument is mandatory. The file name required for the password file is operating system specific. Some operating systems require the password file to adhere to a specific format and be located in a specific directory. Other operating systems allow the use of environment variables to specify the name and location of the password file.

For other platforms, consult your platform-specific documentation. In an Oracle Real Application Clusters environment on a platform that requires an environment variable to be set to the path of the password file, the environment variable for each instance must point to the same password file.

This argument specifies the number of entries that you require the password file to accept. The actual number of allowable entries can be higher than the number of users, because the ORAPWD utility continues to assign password entries until an operating system block is filled. For example, if your operating system block size is bytes, it holds four password entries.

The number of password entries allocated is always a multiple of four. Entries can be reused as users are added to and removed from the password file. This argument, if set to Y , enables you to overwrite an existing password file. An error is returned if a password file of the same name already exists and this argument is omitted or set to N.
