GlobalResourceEnter Function


Defines a resource that can be occupied by only a limited number of users. The caller has to wait until the number of users who occupy the resource is less than the maximum number of users who are allowed to occupy the resource. To releases a resource, call the GlobalResourceRelease function.

Note: The time that a virtual user spends in this synchronization function does not influence the transaction busy time.

                     in nCount   : number optional,
                     in nTimeout : number optional ): number;

Return value

  • GLOBAL_ERROR if an error like an invalid number of users for the resource occurred. To get more information, call the GetLastError function.
  • GLOBAL_CANCELED if the waiting period was canceled by the controller.
  • GLOBAL_TIMEOUT if the waiting period exceeded the defined timeout and the user continues the simulation.
  • GLOBAL_PASSED if the user has occupied the resource and continues the simulation.
