19c 密码文件报错：OPW-00029:

报错

[oracle@localhost dbs]$ orapwd file=/u01/oracle/19.2.0/product/dbs/orapwtwocdb password='oracle' force=y

OPW-00029: Password complexity failed for SYS user : Password must contain at least 8 characters.

原因：

这是因为Oracle 增强了密码验证函数：ora12c_verify_function

解决：

1、创建符合密码要求的密码。

2、简单密码需要增加参数：format=12

[oracle@localhost dbs]$ orapwd file=/u01/oracle/19.2.0/product/dbs/orapwtwocdb password='oracle' force=y format=12

说明：

[oracle@localhost dbs]$ orapwd -h
Usage 1: orapwd file= force={y|n} asm={y|n}
          dbuniquename= format={12|12.2}
          delete={y|n} input_file=
          'sys={y | password | external()
                | global()}'
          'sysbackup={y | password | external()
                      | global()}'
          'sysdg={y | password | external()
                  | global()}'
          'syskm={y | password | external()
                  | global()}'

Usage 2: orapwd describe file=

  where
    file   - name of password file (required),
    password
           - password for SYS will be prompted
             if not specified at command line.
             Ignored, if input_file is specified,
    force  - whether to overwrite existing file (optional),
    asm    - indicates that the password to be stored in
             Automatic Storage Management (ASM) disk group
             is an ASM password. (optional),
    dbuniquename
           - unique database name used to identify database
             password files residing in ASM diskgroup only.
             Ignored when asm option is specified (optional),
    format - use format=12 for new 12c features like SYSBACKUP, SYSDG
             and SYSKM support, longer identifiers, SHA2 Verifiers etc.
             use format=12.2 for 12.2 features like enforcing user 
             profile (password limits and password complexity) and 
             account status for administrative users.
             If not specified, format=12.2 is default (optional),
    delete - drops a password file. Must specify 'asm',
             'dbuniquename' or 'file'. If 'file' is specified,
             the file must be located on an ASM diskgroup (optional),
    input_file
           - name of input password file, from where old user
             entries will be migrated (optional),
    sys    - specifies if SYS user is password, externally or 
             globally authenticated.
             For external SYS, also specifies external name.
             For global SYS, also specifies directory DN.
             SYS={y | password} specifies if SYS user password needs
             to be changed when used with input_file,
    sysbackup
           - creates SYSBACKUP entry (optional).
             Specifies if SYSBACKUP user is password, externally or
             globally authenticated.
             For external SYSBACKUP, also specifies external name.
             For global SYSBACKUP, also specifies directory DN.
             Ignored, if input_file is specified,
    sysdg  - creates SYSDG entry (optional).
             Specifies if SYSDG user is password, externally or
             globally authenticated.
             For external SYSDG, also specifies external name.
             For global SYSDG, also specifies directory DN.
             Ignored, if input_file is specified,
    syskm  - creates SYSKM entry (optional).
             Specifies if SYSKM user is password, externally or
             globally authenticated.
             For external SYSKM, also specifies external name.
             For global SYSKM, also specifies directory DN.
            Ignored, if input_file is specified,
    describe
           - describes the properties of specified password file
             (required).

  There must be no spaces around the equal-to (=) character.
