LoadRunner Remote Monitoring

following three services are enabled for the monitored WINXP system: Remote Procedure Call (RPC), remote registry service, and Remote Registry. In the Remote Procedure Call (RPC) Locator logon option, enter the current host account and password, and then restart the service. Other service settings remain unchanged. Note: you only need to enable the Remote Procedure Call (RPC) and remote registry services on the Internet. If you are not sure about the Windows version you are monitoring, Window

LoadRunner IP Spoofing

First, why to set IP spoofing1, when an IP access is too frequent, or the traffic is too large, the server will deny access requests, this time through IP spoofing can increase the frequency of access and traffic, in order to achieve the effect of stress testing.2, some servers configured load balancing, using the same IP can not detect the actual performance of the system. IP spoofing in LR by invoking different IPs can largely simulate the ability to actually use multi-IP access and test serve

LoadRunner recording script problems

1. You cannot open ie During script recording. There are two reasons: one is that multiple browsers may be installed, and the solution is to open the IE option --- advanced -- remove the check box for "enable third-party browser extension (requires restarting )" Second, Run "register_vugen.bat" again (location \ Program Files \ mercury \ LoadRunner \ bin) 2. An IE running error occurs during script recording. Cause: GenerallyOperating SystemTh

LoadRunner timeout and error

LoadRunner defines the "Response Time" from the client perspective. When a client request is sent, LoadRunner starts to calculate the response time until it receives the response from the server. At this time, the problem arises: if the server Queue is full and the server resources are busy, the request will reside in the server thread. In other words, this new request does not really load the server, but u

Turn: LoadRunner -- block technology

When LoadRunner is used, this problem is often encountered. What should I do if I loop different transactions for different times? By default, LR executes all the transactions in a unified manner. That is, although multiple transactions exist, the number of cycles they are executed is the same, so how does LR implement cycles of different transactions or cycles of different percentages in a script? Case: In a script, what should I do if I want to imp

In-depth understanding of browser emulation in LoadRunner
