In Microsoft SQL Server 2008, database administrators (DBA) are the most important roles. DBA's goal is to ensure that the Microsoft SQL Server 2008 system runs properly and efficiently. DBA is also the busiest job. Both Performance adjustment and disaster recovery are inseparable from DBA support. Generally, as a DBA,

are using the sub-Library, so the original master library data can not be! But the database name is still the same, so there is only one additional instance! The total library cannot be, how to summarize the library data into a complete total library? used in the past, now the full backup of the sub-Library to restore to the total library server and use a different name, downtime maintenance, the sub-Libra

SP2 (with CU6), or 2008, 2008R2 is recommended. Make sure that the mirror and principal server are the same SP and SQL Server version. Use the same collation. The maintenance plan does not support mirroring and requires additional programming to handle the state field in sys.databases. Described in the "

some special-purpose fixed database roles. You can add any database account and other SQL Server roles to a database-level role. Each member of a fixed database role can add other login names to the same role. Important: Do not add a flexible database role as a fixed-role member. This will lead to unexpected permission upgrades. The following table shows the fixed database-level roles and their actions tha

add members to the db_owner fixed database role. MSDB databases also have some special-purpose fixed database roles. You can add any database account and other SQL Server roles to a database-level role. Each member of a fixed database role can add other login names to the same role. Important: Do not add a flexible database role as a fixed-role member. This will lead to unexpected permission upgrades

The factors that affect the database restoration speed are the same as those that affect the database backup speed. In addition, if you use SQL Server 2005, you can start another optimization task to restore a database that does not exist currently. The running environment is Windows XP, Windows 2003 Server, or an updated version. Perform Volume

, and then click "Next ". 33. After the resource is added, "MDaemon Server" appears in "group 0". After it is online, the system automatically starts MDaemon. At this point, the MDaemon cluster is implemented based on the SQL Server storage account. Then, we can create an email account for webmail login to check whether the connection between MDaemon and the

For example, don't let everyone else's salary be accessed casually. 4, decide which users need to update the data, and then assign the appropriate license. Account managers should be able to view the information of all users, but programmers must limit the permissions to update the information. In particular, only the manager who is responsible for a particular account is the only person who can change the user's data. You can
