 This topic provides information that you can use to prepare your environment for installing the product. 

Preparing for installation on a Windows computer

Ensure that you meet the following requirements for installing the product on a Windows computer:

  • Read the Planning topic.
  • Verify that your environment meets system requirements.
  • Download and unzip the zipped product files (the installer) at your preferred location.
  • Ensure that the ports that you use for installing the various components are not in use.
  • As a non-admin user, ensure that you have the following permissions to install the product. 
    (Generally, admin users are expected to already have these permissions.)

    • Write permissions to the directory in which you want to install the product.
    • Write permissions to the C:\Windows directory; this is needed by the installer to create the ProductRegistry.xml file.

      Recommendation

      BMC recommends you to not modify the location and the content of this file to avoid any upgrade issues.

  • Ensure that the host name to IP address mapping is correctly set in the hosts file at C:\Windows\System32\drivers\etc\hosts.
    This is necessary to ensure that the communication between the product components works properly.

Preparing for installation on a Linux computer

  • Read the Planning topic.
  • Verify that your environment meets system requirements.
  • Download and unzip the zipped product files (the installer) at your preferred location.
  • Ensure that the ports that you use for installing the various components are not in use.
  • As a non-root user, ensure that you have the following permissions to install the product:
    (Generally, root users are expected to already have these permissions.)
    • Write permissions to the directory in which you want to install the product.
    • Write permissions to the following directories:

      • /opt directory: Needed by the installer to create the ProductRegistry.xml file.

        Recommendation

        BMC recommends you to not modify the location and the content of this file to avoid any upgrade issues.

      • /etc directory: Needed by the installer to set up environment variables and to store the startup scripts.

      Alternatively, you can provide write permissions to the following locations:

      LocationNeeded to...
      /opt/bmc/ProductRegistry.xml fileMaintain registry of the BMC product installations on the host.
      Note that you need to create the opt/bmc directory.
      /etc/profile file, /etc/csh.cshrc file, and /etc/bmc.profile fileSet up the product environment variables.
      Note that you need to manually create the /etc/bmc.profile file.
      /etc/init.d directoryStore the service startup scripts.
  • Ensure that the host name to IP address mapping is correctly set in the hosts file at /etc/hosts.

    This is necessary to ensure that the communication between the product components works properly.

  • Perform the following steps to prepare for the installation:
    1. Download the .tar.gz file and then unzip and extract the file.
    2. Access the command-line interface and change to the directory that contains the last extracted file; for example: /opt/BMC-TrueSight-IT-Data-Analytics/Disk1.
    3. To perform the installation on a remote Linux computer, enable the X Window System and set the DISPLAY variable to launch the installer user interface. To do so, run the following command:
      DISPLAY=hostName:0.0
      export DISPLAY


      where hostName refers to the name of the computer on which you want to launch the installer.

    4. To enable the Indexer to manage more data, navigate to the /etc/security/ directory and increase the number of open file descriptors on your installed location to at least 32,000.
      To do so, add the following lines in the limits.conf file:

      root soft nofile 32000

      root hard nofile 32000

    5. Save the limits.conf file.
    6. To help prevent performance issues, execute the ulimit -l unlimited command to set the amount of memory that can be locked by the Indexer.

Install the product in one of the following ways:
