T-CODE:RZ11
修改運行中實例的參數，修改完馬上生效，不用重啟實例。重啟實例，參數修改失效.有部分參數你會發現，進入RZ11后發現只能查看不能修改，一種原因是這個參數不在RZ10中存在，如果排除這個原因，其他的原因我也不清楚。
1?Authorizationupdates completed without loggingoff
auth/new_buffering to?該參數設為4,權限的修改將立即起作用,不用用戶重新登錄. 如果有其他疑問請查閱note209899.
2?Preventing multipledialog user logons
login/disable_multi_gui_login該參數可以設置同個client同個用戶ID可以允許同時登錄幾個,當設為1時,系統將提示用戶選擇: 'Terminate theCurrent Sessions' or 'Terminate this Login.',以達到保證只允許一個登錄.
3Profile Parameters for Logon andPassword (Login Parameters)
To make the parametersglobally effective in an?SAP?System (system profileparameters), set them in the default system profile DEFAULT.PFL.However, to make them instance-specific, you must set them in theprofiles of each application?server?in your SAPSystem.
?
| 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 8characters. |
| 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) inpasswords. 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 thepassword Permissible special characters are, in particular, !"@$%&/()=?'`*+~#-_.,;:{[]}<>|and space After SAP NetWeaver 6.40, all characters that are not lettersor digits are regarded as special characters. Default value: 0; permissible values: 0 – 40 Available as of SAP Web AS 6.10 (Until SAP NetWeaver 6.40(inclusive), up to 8 characters.) |
| login/password_charset | This parameter defines the characters of which a password canconsist. Permissible values: ·???????0(restrictive):The password can only consist of digits, letters, and the following(ASCII) special characters :!"@$%&/()=?'`*+~#-_.,;:{[]}<>|and space ·???????1(backward compatible, default value): The password can consist ofany characters including national special characters (such as ?, ?,? from ISO Latin-1, 8859-1). However, all characters that are notcontained in the set above (for value = 0) are mapped to the samespecial character, and the system therefore does not differentiatebetween them. ·???????2(not backward compatible): The password can consist of anycharacters. It is converted internally into the Unicode formatUTF-8. If your system does not support Unicode, you may not be ableto enter all characters on the logon screen. This restriction islimited by the codepage specified by the systemlanguage. Withlogin/password_charset = 2, passwords arestored in a format that systems with older kernels cannotinterpret. You must therefore only set the profile parameter to thevalue 2 after you have ensured that all systems involved supportthe 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 bedifferent 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/password_change_for_SSO | If the user logs on with Single Sign-On, checks whether theuser must change his or her password. Available as of SAP Web AS 6.10, as of SAP Basis 4.6 bySupport Package |
| login/disable_password_logon | Controls the deactivation of password-based logon This means that the user can no longer log on using apassword, but only with Single Sign-On variants (X.509 certificate,logon ticket). SeeLogonData?Tab Page Available as of SAP Web AS 6.10, as of SAP Basis 4.6 bySupport Package |
| login/password_logon_usergroup | Controls the deactivation of password-based logon for usergroups Available as of SAP Web AS 6.10, as of SAP Basis 4.6 bySupport Package |
| login/min_password_lowercase | Specifies how many characters in lower-case letters a passwordmust 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 theadministrator) that the system stores and that the user cannot useagain. Permissible values: 1 – 100 (unit: number of entries); defaultvalue 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 followingmeaning: 0 Withlogin/password_downwards_compatibility=0,passwords are stored in a format that systems with older kernelscannot interpret. The system only generates new (backwardincompatible) password hash values. 1 The system also generates backward compatible password hashvalues internally, but does not evaluate these for password-basedlogons (to its own system). This setting is required, if thissystem is used as the central system of a Central UserAdministration that systems that only support backward compatiblepassword hash values are also connected to the system group. 2 The system also generates backward compatible password hashvalues internally, which it evaluates if a logon with the new,non-backward compatible password failed. In this way, the systemchecks whether the logon would have been accepted with the backwardcompatible password (truncated after eight characters, andconverted to upper-case). This is recorded in the system log. Thelogon fails. This setting is to allow the identification ofbackward incompatibility problems. 3 As with 2, but the logon is regarded as successful. Thissetting is to allow the avoidance of backward incompatibilityproblems. 4 As with 3, but no entry is created in the system log. 5 Full backward compatibility: the system only creates backwardcompatible password hash values. Available after SAP NetWeaver 6.40 |
| login/password_change_waittime | Specifies the number of days that a user must wait beforechanging the password again. Permissible values: 1 – 1,000 (unit: days); default value1 Available after SAP NetWeaver 6.40 |
| login/password_compliance_to_current_policy | Permissible values: 0 – no check; 1 – the system checks duringpassword logon whether the current password complies with thecurrent password rules and forces a password change if this is notthe 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 usedfor authentication. The user administrator can reactivatepassword-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 (apassword chosen by the administrator) remains valid if it is notused. After this period has expired, the password can no longer beused for authentication. The user administrator can reactivatepassword-based logon by assigning a new initial password. This parameter replaces the profileparameterslogin/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 |
