The w3wp occupancy rate in the discovery process is too high. After the query, found as follows: W3wp.exe is a process that is associated with an application pool in IIS (Internet Information Server), and if you have multiple application pools, there will be multiple W3wp.exe process instances running. This process is used to allocate a large amount of system resources. This process is of great importance t

I tested it on the server with a probe: I found that the physical memory usage is so high, I think the memory is not enough? This is not the case: high memory

minutes, etc.), in this way, the primary server to the backup server is usually asynchronous update, so the primary server and backup server data are not guaranteed to be consistent. In addition, the scheme usually does not implement automatic fault monitoring and failover. Hot backup: The primary server's data is au

more than 50 sites, preferably 30 or less, or the server pressure is very large. In the configuration, I generally put the resource consumption of a large site independent of a pool, general BBS or generated HTML system about 5 stations a pool. Common sites and some enterprise sites share a pool.2, according to the experience of WLMMC, in the case of the server hardware, generally do not limit the use of s

will also increase memory usage. If you have server health monitoring, remember that this frequency should not be too high. Otherwise, health monitoring will become a disease-caused monitoring.Jstat can be used to monitor the GC heap and GC of JVM. For example, the monitoring process refresh every 837 milliseconds and

There are several possible causes of high physical memory usage, while the most common are two: one is to install a bad program, memory is occupied too much, the second is the computer itself is not enough memory. And there are usually 3 ways to fix it: 1. Download some fr

client side. cursoruseresultmixin causes the cursor to use the mysql_use_result () function to get the query result. The result set is stored on the server side and was transferred row by row using fetch operations. cursortuplerowsmixin causes the cursor to return rows as a tuple of the column values. Cursordictrowsmixin causes the cursor to return rows as a dicti

Original link: DB2 Memory usage optimization Recently in doing DB2 benchmark, found that the memory of the database is particularly high, because it is done benchmark test, so the table is not much, and mainly for one of the tables to do the test, when the data of this table is fast to 100 million, with the top query s

1, first of all, how do we judge the memory usage rate is too high? According to some software standards, one is to look at the CPU utilization rate. If the CPU usage is greater than 15%, it is normal for the memory usage rate to

memory, the database read and write efficiency will be higher, the response speed will be faster. This is the best way to use the database.However, in many scenarios, the server is not dedicated to the database, to ensure that other applications on the server can function properly, we must set the maximum memory for t

What is memory usage Memory usage is the percentage of physical memory that systems and applications occupy. When the computer is in standby memory will not increase, but if the more open program,

Recently, some friends have experienced the problem of high physical memory usage of their operating system, and the most common two problems, one is that the physical memory is too low, the other is that the program occupies too much cause. So, what should we do if we're dealing with a

Recently, I was working on the benchmark of DB2 and found that the memory usage of the database was very high. Because the benchmark test was performed, there were not many tables, and the test was mainly performed on one of the tables. Recently, I was working on the benchmark of DB2 and found that the memory

In Linux, the memory usage is too high. The solution has recently encountered a menstrual problem. some old people have asked why there are no other services after the boot, so mem will be used up? Is memory leakage? Do you want to restart the service? The root cause of the problem can be found only when the problem is

Warning, uses mysql_store_result (), and returns rows a S tuples. Dictcursor like Cursor except it returns rows as dictionaries. Sscursor A "server-side" cursor. Like the Cursor but uses cursoruseresultmixin. The use of only if is dealing with potentially large result sets. Ssdictcursor like sscursor except it returns rows
