sql server responding slow

When. Net calls a stored procedure, it may be slow or even timeout, but the execution of the stored procedure will be very fast. Solution: 1. Add option (recompile) to statements that may be time-consuming) 2. When creating a stored procedure, specify the with recompile option in its definition, indicating that SQL server will not cache the Stored Procedure

this SQL is not good. Shielding methods can have a variety of:1. Our procedural logic to judge this type of query if there are inquiries ss_si_id=0 all blocked off2. We change the SQL configuration file, modify the SQL statement We found that the DB server has a large number of this

this principle is not difficult to read, if the set log file increment is too small, it will produce too much vlfs, that is, log file fragmentation, excessive log file fragmentation will slow down SQL Server performance. when SQL Server creates a database, the number of VLF

50 methods to skillfully optimize your SQL Server database There are many reasons for slow query speed. The following are common causes: 1. No index or no index is used (this is the most common problem of slow query and is a defect in programming) 2. Low I/O throughput, resulting in a bottleneck effect. 3. the query i

When you start MySQL, add the parameter--log-slow-queries to log the SQL that executes longer than long_query_time seconds: /usr/sbin/mysqld--basedir=/usr--datadir=/var/lib/mysql --user=mysql--pid-file=/var/run/mysqld/mysqld.pid --skip-locking--port=3306--socket=/var/run/mysqld/mysqld.sock--log-slow- Queries=/var/log/mysql/slow.log Explain to understand the

Title, to turn on MySQL's slow query log, you can set two items in the MySQL configuration file under [mysqld]:Log-slow-queries = D:/soft/phpnow/mysql-5.1.50/test.logLong_query_time = 1Log-slow-queries represents the log book storage location, Long_query_time indicates the execution time unit is seconds, so set up after restarting the MySQL

Label:In the implementation of ERP to customers, often encountered customer purchase requisition approval, particularly slow, a stage to turn 40, 50 seconds or so, 3 stages of almost 3 minutes, the efficiency is very low. The check method is as follows: 1, the database tracking statements, find the execution time of the statement, the results are as follows: 2, as can be seen, the execution of the statement, the time is almost 45 seconds (Drration Un

Artificial Intelligence automatic SQL optimization tools-SQLTuning for SQL Server, SQL-sqltuning In response to this situation, the artificial intelligence automatic SQL optimization tool came into being. Now I will introduce this tool: SQLTuning for

MS SQL Server Query optimization methodThere are many reasons for the slow speed of queries, which are common1, no indexes, or no indexes (this is the most common problem with query slowness, is the flaw in programming)2, I/o throughput is small, creating a bottleneck effect.3, no computed columns are created causing the query to be not optimized.4, Low memory5,

high requirements on space utilization and not particularly high security requirements for large file storage. On the contrary, systems with high security requirements, regardless of the cost, use RAID 10 to write small data volumes frequently. Based on experience and analysis: raid10 is recommended for small I/O database operations, such as ERP applications. Large file storage and data warehouses, such as Medical PACS and video editing systems, from the perspective of space utilization, RAID

does not support integrated security. It uses a Windows 2000 account for verification, which can provide better security and more efficient methods to maintain the centralized management of accounts in the console of SQL Server. However, using integrated security degrades the system performance at some levels. First, if integrated security is used, the effectiveness of online ODBC sharing is severely limit

not think ofActually, it's just the beginning.Why is it so slow before splitting and why did it become so fast after splitting? 　　The implementation of the plan is not to look at, said above, the query is not missing the index, but also do use the index, but does not mean that with the index, the index, it is all right. Because the query condition is more complex, the related table establishes the compound index, if to say the index, must say the sta
