Its output is confusing many times so I will try to cover how to draw inference from DBCC MEMORYSTATUS output. I would not talk about each clerk in DBCC MEMORYSTATUS output for that please refer to see also .Look at the article'How to use DBCC MEMORYSTATUS command to monitor memory usage'...
• SQLServer:SQL Statistics\SQL Compilations/sec • SQLServer:SQL Statistics\SQL Re-Compilations/sec Index Searches比Full Scans高个800~1000比较理想。对于大于4Gb RAM的机器,Page life expectancy=(RAM/4)*300. 计划高速缓存的使用(Plan Cache Usage) 在SQL Server2005&2008中可以使用sys.dm_exec_query_s...
Another urban legend that CSS deals with day in and day out. The “Monitoring Memory Usage” topic in SQL Server Books Online talks about how to monitor SQL Server memory usage. None of the tools you typically use to inspect application memory use (Task Manager, Perfmon/Sysmon, etc.) show...
problem. SQL Server 2005 will use as much memory as it's able to when necessary, but will respond to memory pressure requests from the OS to free up memory. The sudden memory usage you're seeing is probably the buffer pool expanding to allow more of the database to be held in memory...
SSIS 2008 SCD wizard does not show non-SQL Server connections This change has been implemented due a problem/limitation on non SQL OLEDB that generated invalid... Date: 11/27/2008 SQL Server checkpoint problems On high end performance servers with a huge amount of memory you might notice some...

By addressing the highest resource consuming queries, you may be able to improve the overall performance of your SQL server without needing to add resources. However, you may have noticed that memory usage is not addressed here. This is because the memory used is dependent on the amount of da...
each pool's CPU and query execution memory usage, but not the amount of I/O resources they use. So, I'd like to institute a chargeback mechanism that helps me amortize the cost of upgrading to a new SAN (storage area network) by billing each team for I/O usage on that server. ...
Frequent garbage collection can be either due to higher memory usage or memory leaks. Ensure that the sum of the maximum heap size of all the JVMs running on your system does not exceed the amount of available physical RAM to avoid operating system level paging activity. Use the JRockit miss...
(CTRL+SHIFT+F) or useSQLCMDto generate the output into a CSV/TXT file. This would help optimize the memory usage on the box that is executing the query and also prevent re-execution of the query due to client box out-of-memory conditions. IMHO I cannot fathom the need to output a ...
