Embodiment Construction

[0015] The present invention will be described in detail below with reference to the accompanying drawings.

[0016] A kind of method of solving SQL SERVER user isolation under the cluster environment of the present invention, the principle description in its structure is as follows:

[0017] (1) Obtain the current isolated user sp_change_users_login 'report', use the database command to modify its status to normal;

[0018] (2) In the windows environment, write an executable script, write the script authorize.sql, the function is to modify the status of the isolated user, in the Windows command line (CMD), osql executes the authorize.sql script;

[0019] (3) During resource migration, execute the osql command:

[0020] Write a batch file script_osql.bat to call the authorize.sql script:

[0021] According to the configuration requirements of the cluster, add script_osql.bat to the cluster to realize the management of scripts by the cluster:

[0022] Set script_osql.bat res...

Abstract

The invention provides a method for overcoming SQL SERVER user isolation in a cluster environment. The method comprises the steps: first, obtaining a current isolated user sp_change_users_login'report', and correcting the state of the isolated user to be normal by using database commands; then writing an executable script in the windows environment, writing the script authorize.sql which has the function of correcting the state of the isolated user, in the Window command line (CMD), executing the authorize.sql script by osql; lastly, during resource migration, executing an osql command, and setting a script_osql.bat resource dependence relation, namely, executing the script after a database is started. The method provided by the invention can automatically eliminate the 'isolated' user, and change the state of the user to be normal, the continuity of the database and user business is ensured, and the method has good using value.

Description

technical field [0001] The invention relates to a method for solving the isolation of SQL SERVER users in a cluster environment. Background technique [0002] For the Microsoft SQL Server application in the cluster, when using a custom user (non-sa), the user is in an "orphaned" state after resource migration (failover), so the client cannot connect to the database, and the high availability function of the cluster is lost. [0003] The so-called isolated account means that it exists in the sysusers system table of the user database, but there is no corresponding record in the syslogins of the master database. That is to say, the account only has a user name but no login name, so it cannot be logged in. Contents of the invention [0004] The purpose of the present invention is to provide a method for solving the isolation of SQL SERVER users in a cluster environment. This method can automatically eliminate "isolated" users and turn them into normal states to ensure the co...
