stable. Generally, the memory usage will not increase after about 27%. These parameters are not optimal and need to be explored. In addition, I also played the Jprobe software used to find out the memory leakage. It is true that other code has no obvious Memory leakage. [Correction: no dog P is used in the above parameter configuration, and the memory is always rising. I also tried to use other methods to reclaim the memory, and the results were not

The reputation of Java is obviously very different from what it has achieved in desktop applications (GUI programs). So far, it is rare to see very successful Java Desktop programs. Although there are large software such as JBuilder, netbean, and Jprobe, this still cannot prove that the Java GUI program is successful: their appearance is always incompatible with other software on the same operating system platform. There seems to be endless demands fo

bottlenecks can exist in any part of the system-networks, databases, clients, or application servers. It is important to first determine which system component causes performance problems. debugging a wrong component may make the situation worse.WebLogic Server provides the system administrator with two methods: console and command line tool to monitor system performance. The server has a collection called mbean, which is used to collect information such as thread consumption, resource surplus,

the database query. In general, if you take 100,000 records to memory at a time, you can cause a memory overflow. This problem is more covert, before the online, the database less data, not prone to problems, on-line, the database more data, a query may cause memory overflow. Therefore, query the database query as much as possible by paging. L Check if the list, map, and other collection objects are not cleared after use. Collection objects such as List, map, and so on will always have a re

certainly true, when it is more important to find the bottleneck code that affects the performance of the program. In order to find these bottleneck codes, we usually use some auxiliary tools, such as jprobe,optimizit,vtune and some analytical tools such as TOWERJ performance. These assistive tools can improve the performance of your program by tracking the time it takes to execute each function or method in your application. (4) Hardware and operati
