SAS9.3 64bit version Installation GuideWith a new computer, after installing the original SAS9.2 , the enhanced editor has been unable to load, tried various methods and wasted the day. Helpless download SAS9.3 version, but the installation is not smooth, of course , the main problem is the JDK , referring to the Netizen's article, successfully completed the installation, another note operating system for Win7 version. Original address:http://f.dataguru.cn/thread-161588-1-1.html1, the main proc

begins, JMeter will wait as necessary until the start time is reached. 　　 At the end of each loop, JMeter checks to see if the end time has been reached and, if so, stops running, or the test continues until the iteration limit is reached. 3, the controller (controllers) JMeter has two kinds of controllers: Sampler and logic controller. 　　The processing of these drive tests. The sampler tells JMeter to sen

One, script recording (Jmeter): Jmeter script (. jmx) is in XML format, tree structure, composed of components, using "sampler" to generate the request. Add "HTTP Proxy Server" port to "Workbench": Proxy server port, default 8080, can modify itself, but do not apply port conflict with it destination controller: the location where the recorded script is stored, the selectable items are grouped into the thread groups in the test plan: groups the request

Previous blogs have introduced the scope of components in JMeter, where the scope of the logical controller (logic Controllers) is only valid for sampler of its child nodes, and the logical controller's role is to control the order in which the samplers are executed.The JMeter provides 17 logic controllers, each of which can be divided into 2 types of use:①. Control the sequence of logical execution of the nodes during the execution of the test plan,

First, jmeter important components:1) Configure Element---config element:Used to initialize default values and variables so that subsequent samplers can be used. Configuring the initial stage processing of a component's scope, the configuration component is valid only for the branch of the test tree in which it resides, such as before any sampler in the same scope.2) predecessor processor---PRE processors:The predecessor processor does some special wo

1. Foreach ControllerThe foreach controller reads a series of related variables in a user-defined variable. The sampler or controller under the controller will be executed one or more times, each time reading a different value of the variable. So foreach is always used with the user Defined variables. The usage of it is described in the following instance.Control PanelParametersName: Controller namesComments: RemarksInput Variable Prefix: Enter variab

It specifies the time it takes to start all threads, for example, the current setting means "Start 5 threads in 1 seconds, each thread has a 0.2-second interval." If you need jmeter to start all threads immediately, set this to 0Number of cycles: Indicates how many requests each thread executes.3.

components Configuring ComponentsConfiguration components (config dlement) are used to provide support for static data configuration. For example, CSV Data set config can form a local Reiki file into a data pool. Timers (timer)Timers are used to set the wait time between operations, and the wait time is a common means of controlling the client's QPS in performance testing. The "Think Time" type in LR. JMETERP defines different types of timers, such as bean Shell Timer, Constant throughput tim
