Upgrading › How to Install or Upgrade CA Service Catalog in Silent Mode › Complete the Prerequisites

Complete the Prerequisites

Complete the following prerequisites so that you can install or upgrade CA Service Catalog in silent mode:

• General prerequisites
  • Verify that you have reviewed and followed the instructions in the Prepare to Install or Upgrade CA Service Catalog scenario. This scenario explains the preparation tasks for installing or upgrading CA Service Catalog and provides guidelines to determine your system architecture.

    Note: The Prepare to Install or Upgrade CA Service Catalog scenario is in the Implementation Guide and on http://ca.com/support.

  • If you are installing CA Service Catalog, complete the installation prerequisites.

    Note: For details, see the Install CA Service Catalog scenario. This scenario appears in the Implementation Guide and on http://ca.com/support.

  • If you are upgrading CA Service Catalog, complete the installation prerequisites.

    Note: For details, see the Upgrade CA Service Catalog scenario. This scenario appears in the Implementation Guide and on http://ca.com/support.

• Prerequisites for the properties files
  • Rename the installer_template.properties file to installer.properties.
  • Rename the config_template.properties file to config.properties.
  • Specify custom values in the installer.properties and config.properties files.

    Note: These files are on the CA Service Catalog installation media. For help determining the appropriate value for any parameters, see the descriptions of equivalent parameters in the Install CA Service Catalog and Upgrade CA Service Catalog scenarios.

  • The location of the properties files varies, depending on the location of the CA_Service_Catalog.exe file. The config.properties file must be in the same location as the CA_Service_Catalog.exe file.
• Prerequisites for performing the installation
  • If a properties file contains errors, or if the target computer does not meet the requirements (for example, the system requirements), the silent installation aborts silently. Therefore, prepare for and verify silent installations carefully.
  • Typically, installation is a one-time task that administrators perform using either the UI installation or the silent installation, but not both. However, if a silent installation fails, you can update the values in the properties files and can retry the installation. Moreover, you can also rename the properties files back to installer_template.properties and config_template.properties, and use the UI installation instead.
