HP has announced its newer version of its flagship tool HP LoadRunner 11.52. LoadRunner 11.52 has major changes in Virtual Table Server (VTS). In this blog post, we will see about the new features of Virtual Table Server of HP LoadRunner 11.52.
What is Virtual Table Server in HP LoadRunner?
Virtual Table Server is a tool that enables sharing of test data and parameters between LoadRunner Virtual Users (VUsers). Usually performance testers use parameterization in their scripts, but in Virtual Table Server it acts as centralized repository to store data which can be shared between VUsers during the test execution.
Below is the revamped design of new VTS.
Differences between old VTS and new VTS
Old VTS was a windows based application. New VTS is a web based application. By default, it can been accessed using http://localhost:4000, since it is a web based, we can access it remotely and it support IE, Chrome, and Firefox browsers. It runs as windows service; during start up it will automatically starts. Basic authentication and https can be enabled to access remotely.
Old VTS utilizes memory, sometime it might crash. But in new VTS, it is disk oriented using NoSQL data engine which enables high throughput.
You need to include #include “vts2.h” statement and some manual work needs to be done like loading DLL file in each load generator machine. But in new VTS, no need to include the statement and loading DLL files.
New VTS has been integrated to run logic where we can control the execution. Old VTS doesn’t have such integration.
New VTS is now available for Linux Load generators as well.
New VTS now supports Unicode.
Data size also increased. HP has tested up to 10 million rows of data. Performance is consistent.
Old VTS was not supported by HP. But HP fully supports VTS.
How to install/upgrade new VTS?
Install HP LoadRunner 11.52 in all machines including load generators
Install VTS on a server machine
After installation, by default VTS can be accessed using 4000 port, which can be changed.
