Oracle databases often encounter high CPU utilization. How can this problem be solved ?, Oracle Utilization Query the SQL statements executed by processes based on the number of processes that occupy the cpu: SELECT sql_text FROM v$sqltext a WHERE (a.hash_value, a.address) IN (SELECT DECODE(sql_hash_value, 0, prev_hash_value, sql_hash_value), DECODE(sql_hash_val

LZ develops an in-house application for querying hive data usage. There is always a high CPU situation after deployment, and local testing is difficult to reproduce. The previous several times have been repeated through the direct restart after the use of, because it is internal use, reboot is not a big impact (of course, each reboot is incidentally changed the bug, add some monitoring, or modify some param

High Linux cpu usage debugging After the top command is used to debug the program today, the cpu usage of the program is found to be very high and it has been running at 99. This is terrible, so we can debug the program. Use the top command to obtain the following results: Pid user pr ni virt res shr s %

The following is a simulation process in Linux1. Simulate high CPU usage in a session, as shown below:DeclareNum int: = 0;BeginLoopNum: = num + 1;End loop;End;/ 2. Run the top command in the shell window to view CPU usage:Pid user pri ni size rss share stat % CPU % MEM TIME

Scenario: A 400-700 requests/Sec web app encounters a high CPU problem after a major revision. When the load increases, the system starts to slow down accordingly. Basics: This article focuses on the process of problem analysis.

A text message alert was sent at noon, indicating that the CPU usage of the Web server is high. It is occupied by Java processes, and the internal system traffic is very small (less than 300). Therefore, high CPU utilization on the server is abnormal, and there are not many log errors. After killing and restarting, the

The solution of Win7 system Svchost.exe consuming CPU resource excessively First look at the task Manager under the Svchost.exe occupies 47% of the CPU resources, at a high time to achieve more than 80% We first right click on the taskbar space, and then in the pop-up menu, select the Start Task Manager menu item Click the View/Select C

How to locate Java threads with high CPU usageTools:1Jstack:jstack is used to print the Java stack information for a given Java process ID or core file or remote Debugging service, if it is on a 64-bit machine, you need to specify the option "-j-d64", The Jstack usage of Windows only supports the following way. pidstat : pidstat is primarily used to monitor all

1. Open Task Manager, turn off some CPU-intensive processes, but do not close the process of system Idle process, which is the process of systems management, In addition there are many svchost.exe, these processes also do not casually shut down, otherwise it will cause shutdown or system reboot. 2. In the

Recently responsible for the SVR pressure is large, business logic is a little more complex, can optimize the place has been all optimized, Currently 3k per second, CPU load is still relatively high Top look, 4 core CPU load is not too balanced, it is intended to consider the business process is assigned to 3

Label:Trigger reason: At the end of the month when the system checkout the operation of the ERP more, there is a user feedback system between the data transmission for a long time without synchronization. Then to the server to view, did not find a program caused by the problem, looked at the CPU utilization, found that the SQL Server occupancy rate of more than 90%.Resolution process: First Baidu, look at t
