The ALM license is configured as part of the ALM installation process and is managed in Site Administration. For more information about the ALM license, see the HPE Application Lifecycle Management Administrator Guide: Managing Licenses.

There are two types of Performance Center licenses:

• PC. The PC license is limited by the total number of concurrent runs or Vusers, and may have an expiration date.

  Note: This license is also available as a free permanent community license bundle. This bundle includes 1 Controller allowing 1 concurrent run, and 50 PC Vusers.

• PC_VUDS. A Virtual User Day (VUD) license provides you with a specified number of Vusers (VUDs) that you can run an unlimited number of times within a 24 hour period (the Virtual User Day). At the end of a Virtual User Day, the remaining number of licensed VUDs is calculated by subtracting the number of used VUDs, or in the case of concurrent usage, the maximum number of concurrent running VUDs, from the total number of licensed VUDs.
  

  For example, a user has a license that allows him to run 1,000 VUDs. He creates a performance test that requires 200 Vusers and runs for 45 minutes. He runs the test at 8:00 am, 10:00 am, 2:00 pm, and at 4:00 pm. In each case, the test finishes before the next one begins. Because there is no concurrent Vuser usage, he can re-use the same 200 VUDs for each test run, meaning that at the end of the 24-hour period, only 200 VUDs are deducted from the license, leaving 800 for future use.

  However, if the user starts the second run at 8:30 am, the first test is still running before the second test initializes. This overlap requires 400 Vusers to run concurrently (200 for each test). At the end of the day, 400 VUDs are deducted from the license, because that is the highest number of concurrent Vusers. The total left for future use is 600 VUDs.

  Note:  

  • The Performance Center and Host licenses are configured directly after installation of the Performance Center Server. You configure the licenses using the PC Licenses Module window. For more information, see PC Licenses Module Window.

  • You can run VUDs on HP developed protocols, with the exception of: COM/DCOM, VB Com, VB Vuser, VB Script Vuser, VB.NET Vuser, and VB.NET Template.

  • You cannot run VUDs on SDK protocols.

  • You cannot run VUDs on a GUI Vuser script, such as UFT Professional scripts.

  • When using a VUD based Performance Center license, a Host license is not relevant.

The Host license defines the limits of Vuser use per protocol on the host. There are two host license Vuser types:

• <bundle type> Bundle. Each bundle contains a collection of protocols. When you select a protocol bundle, this section displays a list of included protocols.

• Global. The global license lets you run all Vuser types, provided you stay within the total limit. The number following "Global" indicates the total number of Vusers purchased.

Performance Center is delivered with a free perpetual community license bundle. The bundle includes:

1 Controller allowing 1 concurrent run, 1 PC Lifecycle user, and 50 permanent Vusers. These Vusers are valid for all protocols except for GUI (UFT), COM/DCOM, and template protocols. The community license bundle does not include support.
