Set rendezvous policies

This topic describes how to set rendezvous policies that determine how the Controller handles Vusers at a rendezvous point, and how to manually release Vusers from a rendezvous.

Rendezvous points

Rendezvous points are used in performance testing to simulate multiple Vusers performing actions simultaneously. They are inserted into the Vuser script using VuGen (Virtual User Generator). For information, see the OpenText Virtual User Generator Help Center.

The Controller manages when Vusers are released from the rendezvous point according to the policy attribute you set. This helps simulate peak load conditions and measure how the server handles concurrent user activity.

Example:  

Suppose you want to measure the performance of an application when 10 Vusers perform a task simultaneously. To make sure that multiple Vusers act simultaneously, you create a rendezvous point in the Vuser script. When Vusers arrive at a rendezvous point, they are held there by the Controller. The Controller releases the Vusers from the rendezvous either when the required number of Vusers arrives, or when a specified amount of time has passed.

For each rendezvous point, you can set Policy attributes. During the test run, you can manipulate the Vuser behavior at the rendezvous points.

For example, to test an online bank, you could create a test that contains two rendezvous points. The first rendezvous ensures that one thousand Vusers simultaneously deposit cash. The second rendezvous ensures that another thousand Vusers simultaneously withdraw cash. To measure how the server performs when only 500 Vusers deposit cash, you can set the release policy so that the Vusers are released when 500 Vusers arrive at the rendezvous.

Configure rendezvous policies

You can configure rendezvous policies when defining the test workload. This determines how the Controller handles Vusers at a rendezvous point. You can also activate and deactivate rendezvous points defined in the Vuser scripts.

Note: The user interface was modernization in 25.3 and these updates are reflected in the help. While some steps may differ slightly in 25.1, the core functionality remains the same.

To configure and activate rendezvous points:

  1.  In the banner, click the module name or arrow and select Test Management > Tests & Scripts. Select a performance test in the test management tree and click Edit Test.

  2. In the Groups and Workload view, select More > View Rendezvous. The Rendezvous Points dialog box opens, displaying any rendezvous points defined in the script.

    Attribute Description
    Rendezvous Name

    The name of the rendezvous point as provided in the VuGen script.
    Contained on # of Scripts

    The number of scripts in which the rendezvous point was defined.

    Click Show Script Names to display the names of the scripts in which the rendezvous point was defined.
    Enable A check mark indicates that the selected rendezvous point is enabled.

  3. Set the policy attributes for each rendezvous to determine how the Controller handles Vusers at a rendezvous point.

    1. Click a rendezvous point to select it, and set the following attributes.

      Attribute Description
      Enable Rendezvous

      To enable rendezvous points, select the points you want to enable and click Enable Rendezvous (clear the check box to deactivate rendezvous points). Activating or deactivating a rendezvous point influences the level of server load.

      A check mark in the Enable column indicates that the selected rendezvous points are enabled.
      Release when

       

      Sets how many Vusers are released from a rendezvous point at a time.

      • X% of Running Vusers arrive at the rendezvous. Releases the Vusers only when the specified percentage of all Vusers running in the test have arrived at the rendezvous point.

      • X Vusers arrive at the rendezvous. Releases the Vusers only when the specified number of Vusers have arrived at the rendezvous point.

      • X% of all Vusers arrive at the rendezvous. Releases the Vusers only when the specified percentage of all Vusers have arrived at the rendezvous point.

        Note: This option interferes with the scheduling of the test. When selected, your test does not run as scheduled.
      Timeout between Vusers

      The timeout value in seconds. After each Vuser arrives at the rendezvous point, the Controller waits up to the maximum timeout period specified for the next Vuser to arrive.

      If the next Vuser does not arrive within the timeout period, the Controller releases all the waiting Vusers from the rendezvous.

      Each time a new Vuser arrives, the timer is reset to zero. You set a timeout for each rendezvous point.

    2. Repeat for each rendezvous point.

      Note: The policy section is not displayed when multiple rendezvous points are selected.

  4. Click OK to save your rendezvous policies.

Release Vusers from a rendezvous

You can manually release Vusers waiting at a rendezvous point during a run before the Controller releases them.

  1. In the Run Dashboard (Graphs, Groups, or Transactions tab), select More > Rendezvous / View Rendezvous.

    The Rendezvous dialog box opens displaying details about the rendezvous points in the scripts. For details, see Configure rendezvous policies.

  2. To manually release the Vusers at the selected rendezvous points, click the Release button Release button.

  3. To activate or deactivate rendezvous points, select the points you want to activate or deactivate and click the Activate button or Deactivate button . A check mark indicates that rendezvous points have been activated.

For details on running a performance test, see Run performance tests.
