The rendezvous point for LoadRunner
The rally point in LoadRunner tells Vusers during test execution to wait for multiple Vusers to reach a certain point so they can run a task at the same time. Generates heavy user load on the server for a specific feature/page.
Let’s use an illustration to try to understand the meeting point:
Suppose you want to measure how well a shopping portal application handles concurrent product orders from five V-users. You instruct each V-user to stop before the “Submit Order” transaction to simulate the necessary user load on the server. LoadRunner will release all five Vusers at the same time, or exactly the same time after they arrive. See Figure 01 in the paragraph below to understand the scenario. The meeting point is entered between the ‘Add to Cart’ and ‘Submit Order’ transactions. The image shows that Vusers 2 and 5 should wait after the “Add to Cart” transaction. The ‘Submit Order’ transaction is executed concurrently after all 5 Users have arrived.

How can a rallying point be added to the LoadRunner script?
The meeting point can be added to the script in two different ways:
1. Insert while the script is being saved:
VuGen’s recording bar provides the option to insert a meeting point while the script is being recorded. The logo looks like four arrows pointing in the same direction. The text “Insert encounter” is visible when the mouse pointer is over the icon. When you click the icon, VuGen inserts a meeting point between the previously recorded steps and the steps that are now being recorded.

2. After script recording, insert:
You still have the option to add a Meetup Point later if you missed doing so during the recording. You must first right-click on the script where you want to place the meeting point, then hover over “Insert” and choose “Rendezvous” (see Figure 03 below), or you can just click there.

or the VuGen menu (see Figure 04 below). Choose Design > Insert In Script > Rendezvous.

The meeting policy is an additional part of the meeting point. You can configure a rendezvous policy so that the controller releases Vusers from the rendezvous point when the required number of Vusers arrive or after a certain period of time. See the “Encounter Policy” article for more information.
