• 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.
• Ensure that you have the following permissions to install the product:
  
  • 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.

  • Permissions to create an environment variable.
  • Permissions to add a registry key and update a registry key.
  • Permissions to install, start, stop, and uninstall the product services.
• 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.
• Ensure that you have the following permissions to install the product:
  • Write and execute permissions to the directory in which you want to install the product.

  • Write and execute permissions to /opt directory; this is needed by the installer to create the ProductRegistry.xml file.

    Recommendation

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

  • Write and execute permissions to the /etc directory for the installer to create the /bmc.profiles file.

  • Write and execute permissions to the /etc/init.d directory.

• 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. 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.
