utilization

问题 I am looking for a script/process to check the amount of CPU (in terms of percentage) each query consumes at any point of time in my oracle database. My Oracle version is : 12.1.0.2 Database is hosted on Exadata X7_2 It is a shared server, and many databases also running on the same server. SELECT AVG(value/vp.cpu_count) FROM v$sysmetric_history,(SELECT value cpu_count FROM v$parameter WHERE name LIKE 'cpu_count') vp WHERE metric_name = 'CPU Usage Per Sec' AND group_id = 2 AND end_time >

问题 I have to split a huge file into many smaller files. Each of the destination files is defined by an offset and length as the number of bytes. I'm using the following code: private void copy(string srcFile, string dstFile, int offset, int length) { BinaryReader reader = new BinaryReader(File.OpenRead(srcFile)); reader.BaseStream.Seek(offset, SeekOrigin.Begin); byte[] buffer = reader.ReadBytes(length); BinaryWriter writer = new BinaryWriter(File.OpenWrite(dstFile)); writer.Write(buffer); }

问题 I have a large project with lots of classes. It takes 40% CPU when it is running. What is the best way to find out what operations and functions are responsible for the load? I am using Flash Builder 4.5 AS3 Project. Built-in profiler doesn't help me much. Thanks 回答1: You can try SWFWire Debugger. Check the box that says Show method entry . If you also check Show method exit , it will tell you how long each function took to execute. The object graph might also help if you are creating and

问题 Does anybody knows whether it is possible to measure utilization of a server CPU with Selenium RC? I need to know service demand on the devise. Thanks in advance. 回答1: Since you are extending Selenium's capabilities with RC, you can use your programming language's native ability to measure resource utilization. For instance, in Java, try this 回答2: Selenium is just for driving the browser. It doesn't have tools for monitoring CPU usage on the server. However there is a company called Dynatrace

问题 Is there a way do do dynamic elasticity in Windows Azure? If my workers begin to get overloaded, or queues start to get too full, or too many workers have no work to do, is there a way to dynamically add or remove workers through code or is that just done manually (requires human intervention) right now? Does anyone know of any plans to add that if its not currently available? 回答1: There's a Service Management API, and you can use that to scale your application (from code running in Windows

问题 How do I get the CPU usage for each process that is currently running on the local system or server using PHP. How can I use the Command Prompt command tasklist from within PHP and fetch process names and memory information. Here is the example : Name of Processor Memory usage Edit plus 6.1 MB Google Chrome 20 MB Command Prompt 5 MB Tomcat 2.1 MB 回答1: Seeing as you've changed the specification for the answer and I don't wish to remove or butcher my other answer which may be an acceptable
