T-CODE:RZ11
修改运行中实例的参数，修改完马上生效，不用重启实例。重启实例，参数修改失效.有部分参数你会发现，进入RZ11后发现只能查看不能修改，一种原因是这个参数不在RZ10中存在，如果排除这个原因，其他的原因我也不清楚。

Password Checks
|
Parameter |
Description |
|
login/min_password_lng |
Defines the minimum length of the password. Default value: 3; permissible values: 3 – 40 Until SAP NetWeaver 6.40 (inclusive), up to 8 characters. |
|
login/min_password_digits |
Defines the minimum number of digits (0-9) in passwords. Default value: 0; permissible values: 0 – 40 Available as of SAP Web AS 6.10 (Until SAP NetWeaver 6.40 (inclusive), up to 8 characters.) |
|
login/min_password_letters |
Defines the minimum number of letters (A-Z) in passwords. Default value: 0; permissible values: 0 – 40 Available as of SAP Web AS 6.10 (Until SAP NetWeaver 6.40 (inclusive), up to 8 characters.) |
|
login/min_password_specials |
Defines the minimum number of special characters in the password Permissible special characters are, in particular, !"@ $%&/()=?'`*+~#-_.,;:{[]}\<>| and space After SAP NetWeaver 6.40, all characters that are not letters or digits are regarded as special characters. Default value: 0; permissible values: 0 – 40 Available as of SAP Web AS 6.10 (Until SAP NetWeaver 6.40 (inclusive), up to 8 characters.) |
|
login/password_charset |
This parameter defines the characters of which a password can consist. Permissible values: · 0(restrictive): The password can only consist of digits, letters, and the following (ASCII) special characters :!"@ $%&/()=?'`*+~#-_.,;:{[]}\<>| and space · 1 (backward compatible, default value): The password can consist of any characters including national special characters (such as ??, ??, ?? from ISO Latin-1, 8859-1). However, all characters that are not contained in the set above (for value = 0) are mapped to the same special character, and the system therefore does not differentiate between them. · 2 (not backward compatible): The password can consist of any characters. It is converted internally into the Unicode format UTF-8. If your system does not support Unicode, you may not be able to enter all characters on the logon screen. This restriction is limited by the codepage specified by the system language. Withlogin/password_charset = 2, passwords are stored in a format that systems with older kernels cannot interpret. You must therefore only set the profile parameter to the value 2 after you have ensured that all systems involved support the new password coding. Available in the standard system as of SAP Web AS 6.40. |
|
login/min_password_diff |
Defines the minimum number of characters that must be different in the new password compared to the old password. Default value: 1; permissible values: 1 – 40 Available as of SAP Web AS 6.10 (Until SAP NetWeaver 6.40 (inclusive), up to 8 characters.) |
|
login/password_expiration_time |
Defines the validity period of passwords in days. Default value: 0; permissible values: 0 -1000 |
|

|
login/disable_password_logon |
Controls the deactivation of password-based logon This means that the user can no longer log on using a password, but only with Single Sign-On variants (X.509 certificate, logon ticket). SeeLogon Data Tab Page Available as of SAP Web AS 6.10, as of SAP Basis 4.6 by Support Package |
|
login/password_logon_usergroup |
Controls the deactivation of password-based logon for user groups Available as of SAP Web AS 6.10, as of SAP Basis 4.6 by Support Package |
|
login/min_password_lowercase |
Specifies how many characters in lower-case letters a password must contain. Permissible values: 0 – 40; default value 0 Available after SAP NetWeaver 6.40 |

|
login/password_history_size |
Specifies the number of passwords (chosen by the user, not the administrator) that the system stores and that the user cannot use again. Permissible values: 1 – 100 (unit: number of entries); default value 5 Available after SAP NetWeaver 6.40 |
|
login/password_downwards_compatibility |
Specifies the degree of backward compatibility to be achieved. The default value is 1, where the values have the following meaning: 0 Withlogin/password_downwards_compatibility=0, passwords are stored in a format that systems with older kernels cannot interpret. The system only generates new (backward incompatible) password hash values. 1 The system also generates backward compatible password hash values internally, but does not evaluate these for password-based logons (to its own system). This setting is required, if this system is used as the central system of a Central User Administration that systems that only support backward compatible password hash values are also connected to the system group. 2 The system also generates backward compatible password hash values internally, which it evaluates if a logon with the new, non-backward compatible password failed. In this way, the system checks whether the logon would have been accepted with the backward compatible password (truncated after eight characters, and converted to upper-case). This is recorded in the system log. The logon fails. This setting is to allow the identification of backward incompatibility problems. 3 As with 2, but the logon is regarded as successful. This setting is to allow the avoidance of backward incompatibility problems. 4 As with 3, but no entry is created in the system log. 5 Full backward compatibility: the system only creates backward compatible password hash values. Available after SAP NetWeaver 6.40 |
|
login/password_change_waittime |
Specifies the number of days that a user must wait before changing the password again. Permissible values: 1 – 1,000 (unit: days); default value 1 Available after SAP NetWeaver 6.40 |
|
login/password_compliance_to_current_policy |
Permissible values: 0 – no check; 1 – the system checks during password logon whether the current password complies with the current password rules and forces a password change if this is not the case. Default value: 0 Available after SAP NetWeaver 6.40 |
|
login/password_max_idle_productive |
Specifies the maximum period for which a productive password (a password chosen by the user) remains valid if it is not used. After this period has expired, the password can no longer be used for authentication. The user administrator can reactivate password-based logon by assigning a new initial password. Permissible values: 0 – 24,000 (unit: days); Default value 0, that is, the check is deactivated Available after SAP NetWeaver 6.40 |
|
login/password_max_idle_initial |
Specifies the maximum period for which an initial password (a password chosen by the administrator) remains valid if it is not used.

This parameter replaces the profile parameterslogin/password_max_new_validandlogin/password_max_reset_valid. Permissible values: 0 – 24,000 (unit: days); Default value 0, that is, the check is deactivated Available after SAP NetWeaver 6.40 |
