It is responsible for scheduling and driving the population of full-text indexes, and is responsible for monitoring full-text catalogs. Thesaurus FileThese files contain synonyms for the search term.

benchmarks, industry standards, previous versions of the situation How baselines are expressed, including: Batches completed per second (jobs), transfers per second, amount of data per second, disk scan time, etc. Analyze the factors that affect performance: Database design (whether it is a complex paradigm, whether it is reasonable to archive, partition, sub-table, etc.) Software systems (operating system optimization, database system configuration, resource planning and

On-Line Analytical Processing (OLAP) system is the main application of Data Warehouse system, specially designed to support complex analysis operations, focusing on decision support for decision-makers and senior managers, and can quickly and flexibly carry out complex query processing of large amount of data according to the requirements of analysts. And in an intuitive and understandable form of the query results provided to decision makers, so that they accurately grasp the business (company)

the execution statements on all the databases can be monitored. You can also set duration to filter SQL statements for different execution times, such as SQL statements that can be filtered for longer execution times, and select to optimize SQL statements. What if the same database, multi-person access, only want to detect the statement of their own actions? You

advantage is that the availability replica is a standalone instance, so the database copy resides on the local disk where the instance node is running, and if the availability replica is a clustered instance, the database copy is stored on the shared disk.An availability group is a cluster resource from a Windows cluster perspective, where all databases fail over between nodes as a whole, and of course this excludes system databases, which cannot be added to the High Availability group.Because

A single-machine mode SQL Server is recommended here, and the advantage is that the availability replica is a standalone instance, so the database copy resides on the local disk where the instance node is running, and if the availability replica is a clustered instance, the database copy is stored on the shared disk.An availability group is a cluster resource from a Windows cluster perspective, wh

SQL trigger instance 1Definition: What is a trigger? In SQL Server, certain operations on a table trigger certain conditions to execute a program. A trigger is a special stored procedure.There are three common triggers: Insert, Update, and Delete events.Why should I use a trigger? For example, two tables: The code is as follows:Copy code Create Table Student

SQL Server 2008 lowers the management workload of the data platform by introducing scalable policy-based management capabilities. The most notable of these is the declarative Management Framework (DMF), which provides a strategic management, but this name has been enabled and is now the name of policy-based management (Policy Based Management), Let's call it PBM for short. PBM enables DBAs to develop manage

SQL Server currently does not have a large number of MySQL users, but Microsoft's products in terms of ease of use is still very good, some government projects or SQL Server database, there is a SQL Server Web management tool tree

It seems that the problem is not so simple, the author in another system when installed on the Regmon to perform registry operation monitoring, filtered only to monitor the "msiexec.exe:484" process, in the report with the above mentioned errors to save the monitoring log to the file. View the failed situation through the monitoring log.

SQL Server Profiler is a performance monitoring tool for MS SQL. You can use this tool to find the SQL statements to be optimized, and then use the database engine optimization advisor tool to help optimize the database. SQL

also need to configure MDaemon to MDaemon, we strongly recommend that you disable the MDaemon service to avoid unnecessary errors before starting the configuration, because after MDaemon is configured, its monitoring and control has been transferred to MSC. Next, configure the cluster for MDaemon. Open "Cluster Manager" on the current node and create a "resource" in "group 0" in the cluster group where SQL

locks and table locks, resulting in deadlocks. In practical applications, you need to consider the concurrency of SQL operations, real-time requirements, table indexes, data distribution modes, and so on. Each lock type has its most suitable scenarios. You can use management ---> activity monitor to analyze the lock snapshot information in the database.You can use the DBCC command to write lock-related information to the
