How to Improve Performance of CA Process Automation

As you approach how to boost or enhance performance, consider the following guidelines:

• Convert each standalone Orchestrator to a cluster.

  Adding a second node can improve performance by up to 80%. The improvement you achieve depends on many variables, including the CA Process Automation content being run.

• Content
  • Global Datasets

    Minimize references to global datasets, as access to them is serialized. That is, only one object can access a dataset at a time. This guideline applies to writes (not reads).

    The best practice is to make a Process-level copy of the required data and then refer to that process dataset.

  • Inline processes

    Limit the use of launching processes inline to cases in which both of the following are true:

    • There are fewer than 10 operators in the inline process.
    • The inline process is not called inside a loop.
• CPUs
  • Monitor CPU usage on all Orchestrator nodes to determine which nodes could best benefit from additional CPUs or cores.
  • Add more CPUs or cores, as needed.
  • When running in a virtual environment, dedicate the CPUs to the CA Process Automation VMs.
• Memory
  • When running in a virtual environment, dedicate the RAM to the CA Process Automation VMs.
  • Monitor the process memory usage on all Orchestrator nodes to determine whether additional RAM is needed.
• VM server optimization

  Refer to your VM server vendor for instructions on how to boost performance.

• Database optimization and maintenance

  Refer to the your database server vendor for instructions on how to boost and maintain the performance of the CA Process Automation database. Such instructions typically include database re-indexing, the updating of statistics, as well as the monitoring and maintenance of the file system on which data is stored.

• Turn off all unneeded features
  • Catalyst

    If you are not using Catalyst connectors, find the following value in the OasisConfig.properties and change it from true to false:

    # enable connector
    ucf.connector.enabled=true
    

  • Reporting

    If you are not using Reporting, insert the following key value pair into the OasisConfig.properties file. Changes to this file go into effect when the CA Process Automation service is restarted.

    oasis.disable.reporting.manager=true  
    

• VMware

  If using VMware, change the virtual NIC from E1000 to VMXNET3. This change typically improves both performance and reliability.
