How to work with MQ Series protocol in LoadRunner 11.5x and what are the various components and pre-requisite software's to work with this protocol?
Please follow the below steps:
1. Install WebSphere MQ version 5.3 or higher (this can be downloaded from internet)
2. Install ''MQ Tester'' package from LR Main DVDAdditional ComponentsMQTester folder. When running this MQ Tester installer, you will have the option to choose VuGen based component (for scripting), load generator based component (just for the sake of running MQ Tests on a standalone LG) or a full install (which includes both VuGen and LG components. Example: like on a full LoadRunner setup). To choose the VuGen-only option, choose custom type
3. After MQ Tester installation in VuGen or Full install mode, 2 new protocols will appear in VuGen's protocol list: MQ Series Client and MQ Series Server
4. Now you can start recording scripts or make enhancements to the scripts in the regular LoadRunner way using one of these 2 MQ protocol types
