Launching several copies of a step to improve the performance of Atrium Integrator

In certain situations, launching multiple copies of a step improves performance. For example, if a step uses a large amount of CPU (such as a JavaScript step) and you have multiple processor cores in your computer, launching multiple copies of the step might improve performance. If a step has to deal with network latencies, such as a database lookup step, launching the same step several times keeps the database busy on different connections, which lowers the latency.

Best practices

For all data transfer jobs created by using the Integration Job Builder wizard, the CMDBOutput step is set to launch three times. Depending on the configuration of your computer, you can increase the number of copies of the CMDBOutput step to increase the overall throughput of the data transfer job. BMC recommends that you set the number of copies to no more than ten.

You can also use the following formula:

Number of copies=Number of CPUs x 3 threads

To launch several copies of a step

  1. Right-click on the step that you want to launch multiple times, and select Change number of copies to start.
    The Nr of copies of step dialog box appears.
  2. Enter the number of times you want to launch this step, and click OK.
    The number of steps appears in the upper-left corner of the step icon. 

    The following figure shows how Atrium Integrator Spoon indicates that a step has been launched multiple times.
