Configuring after grid installation

The administrator must perform these tasks before using the product (or part of the product) to accomplish user goals.

In the instructions on this page, AO_HOME represents the installation directory for a BMC  Atrium Orchestrator CDP.

Adjust Default group permissions

After installing the primary CDP, you were instructed to remove permissions from the Default group. If you have not already done so, remove permissions before continuing. See Adjust default group permissions for details.

Configure memory settings

For the production (and potentially lower) environments, the number of concurrent jobs and memory consumption of those individual jobs might require a memory increase (increase of the Java heap size) for the BMC Atrium Orchestrator JVMs.

You can check the grid's available and used memory in the grid console by entering the following URL in a browser window:

https://<fullyQualifiedAOgridHostName>:<port>/baocdp/console

You can adjust the server memory by editing the server's Tomcat properties.

The following BMC Communities video (5:28) demonstrates how to increase a BMC Atrium Orchestrator peer's memory on Windows or Linux.

To adjust a CDP server's memory on Windows

  1. Stop the BMC Atrium Orchestrator Configuration Distribution Peer service. See Starting and stopping product components and services.
  2. From the command prompt, go to AO_HOME\tomcat\bin and run the tomcat8w.exe //ES//<CDPService> command.
  3. On the CDP Peer Properties dialog box, click the Java tab.
  4. You can edit the values of the following parameters to determine the heap size:
    • Initial memory pool
    • Maximum memory pool
      Here, the default value of the parameters is Initial memory pool=1024 and Maximum memory pool=1280. Do not increase the Maximum memory pool value (default 1280) to more than half of the computer's total memory. Also, do not increase this value beyond 8192 (8 GB) without consulting BMC Customer Support.
  5. Click Apply and then click OK.
  6. Start the CDP service. See Starting and stopping product components and services.

To adjust a CDP server's memory on UNIX

  1. Stop the BMC Atrium Orchestrator Configuration Distribution Peer service. See Starting and stopping product components and services.
  2. Go to the AO_HOME/bin directory.
  3. Back up the the server.sh file.
  4. Open the server.sh file for editing.
  5. Edit the values of the following parameters to determine the heap size:
    • -Xms
    • -Xmx
      Here, the default value of the parameters is: -Xms1024m and -Xmx1280m. Do not increase the set maxMemSize value (default 1280) to more than half of the computer's total memory. Also, do not increase this value beyond 8192 (8 GB) without consulting BMC Support.

      Important

      There's a slight difference between the default values of the -Xms and -Xmx parameters, however, for optimal performance, BMC recommends that you specify same values for -Xms and -Xmx parameters.

  6. Save the file.
  7. Start the CDP service. See Starting and stopping product components and services.

    Important !!! BMC recommends that you specify the same value for -Xms and -Xmx parameters for optimal performance.

    and the default is "-Xms1024m and -Xmx1280m", Seems a bit funny.

      Stefan, we are working on fixing this.

      The difference between 1024 and 1280 is not great but in case of real environments, the difference in these value can cause issues, hence the note. 

      I will work with the team to get the default values be the same. 

      Thanks for commenting.
