sql server maintenance checklist

Tags: SQL Server remote MaintenanceNow that many applications are in the cloud, the database requires remote management and maintenance, then the web-based approach is more secure and convenient.Treesoft database management software uses the Java development, uses the stable common SPRINGMVC+JDBC architecture, realizes the Web-based method to the

Label:--Maintenance Database----Stored procedure (procedure)----Overview： 　　 A stored procedure for SQl serve is a collection of one or more T-SQL statements。 Common program code Snippets are often created as stored procedures that create multiple invocations at once, simplifying the programmer's work and reducing the network traffic that interacts with the

ObjectiveThe previous article describes how to improve the query performance of a database by building an index, which is really just the beginning. Subsequent to the lack of proper maintenance, the index you created earlier can even become a drag, becoming an accomplice to the decline in database performance.Find FragmentsEliminating fragmentation may be the most common task for index maintenance, and Micr

when using SQL Server High availability features, for example,the XenDesktop site database uses the full transaction logging mode to run database mirroring. transaction logs that run through the full transaction logging mode grow too large until the database space is filled or the transaction log space size is filled. If the transaction log files are not monitored,the configuration log file for

Label:--Maintenance Database---- Trigger -- --Overview：Note:a trigger is a special type of stored procedure，used to enforce business rules。 On invocation, triggers cannot be called directly by the user through T-SQL statements, as stored procedures do, but require the execution of INSERT, UPDATE, delete events that occur on the database to fire the automatic execution of the trigger. Therefore, when creatin

non-overwrite update, it will cause the movement of the data rows during the page splitting process:(1) The move of the clustered index has no effect on the nonclustered index, because the key value of the clustered index is stored in the nonclustered index, and the split does not change the key value;(2) The data page in the heap table splits, leaving a forward pointer at the original record to tell the nonclustered index where to find the new record;So the movement of data rows does not cost

, and the request involves using a partitioned table, the optimizer can optimize the request to find the appropriate data only on the appropriate partition. ( more about the partition table, you can refer to our site published in the "Understanding of the Section table" series of articles )Although it is said that we are talking about distributed partitioned views, in fact, in SQL Server 2005 (and later ver

COLMODCTR will be added)The filter statistics (filtered statistics) trigger updates to the overall data range rather than the filter interval.

To schedule preventive maintenance for the MYSQL database server [team chart], you should consider setting up a schedule for preventive maintenance to help automatically detect problems so that you can take measures to correct them: 1) perform regular database backup and allow log updates. 2) arrange regular table checks. Using the
