The additional part of the rendezvous point in LoadRunner is rendezvous policy. You can set a rendezvous policy according to which the controller releases the Vusers from the rendezvous point either when the required number of Vusers arrives, or when a specified amount of time has passed.
Difference between Rendezvous Point and Rendezvous Policy
- Rendezvous Point is defined in the VuGen (Test script) whereas Rendezvous Policy is defined in the controller (Test scenario)
- Rendezvous Point instructs to LoadRunner ‘Where to stop the Vusers?’. On the other hand, Rendezvous Policy instructs to LoadRunner ‘How to release the Vusers?’
Importance of Rendezvous Policy:
Let’s say you have inserted a rendezvous point and as per definition, all Vusers have to wait until the last one arrives. Due to some issues, the last Vuser did not reach to the rendezvous point and all Vusers halted for a long duration, waiting for stuck Vuser. This will spoil the purpose of the test. To avoid such situation Rendezvous policy is used. Rendezvous policy helps to keep running the test by meeting the provided condition.
How to add Rendezvous policy in a LoadRunner scenario?
Rendezvous points are only effective for group mode with the manual scenario. It is disabled for a goal-oriented scenario. When you add a Vuser group or script to the scenario, LoadRunner scans the included scripts for rendezvous points and adds them to a central list of rendezvous points. In the controller, you have to
1. Select Scenario (Design) > Rendezvous to view this list.
2. Click “Rendezvous…”
3. Click “Policy…”
4. Choose any one option as per your requirement and click ‘OK’
- Release when XXX % of all Vusers arrive at the rendezvous: Let’s say I have 100 Vusers; 20 are in downstate, 20 are in ready and 60 are in run state and I want to release 40% (=40 Vusers) after waiting them for 30 seconds, so I will give 40 as a value in the box.
- Release when XXX % of all running Vusers arrive at the rendezvous: Let’s say I have 100 Vusers; 20 are in downstate, 20 are in ready and 60 are in run state and I want to release 40% of running Vusers(=24 Vusers) after waiting them for 30 seconds, so I will give 24 as a value in the box.
- Release when XXX Vusers arrive at the rendezvous: Let’s say I have 100 Vusers; 20 are in downstate, 20 are in ready and 60 are in run state and I want to release 60 Vusers after waiting them for 30 seconds so I will give 60 as a value in the box.
- Timeout between Vusers YY Sec.: The time the controller waits before releasing Vusers from a rendezvous.
- Rendezvous points are only effective for group mode; not for percentage mode
- In goal-oriented scenarios, a script’s rendezvous points are disabled.
- Do not insert Rendezvous point inside a transaction.
- The Vuser count or percentage in rendezvous policy should be given considerably high so that proper load can be generated on the server and meet the purpose.
