Configuring installation settings for Linux and UNIX

This topic describes how to configure installation settings when installing TrueSight Server Automation components on Linux and UNIX. It includes the following sections:


Methods for reducing installation space on Linux and UNIX

You can reduce the disk space required by a Linux or UNIX installation by setting the installer to read from a shared drive or by setting the INSTALL_FILES_TEMP environment variable. 

The space required for an installation depends on:

  • Size of the installation
  • Space required for expanding installation files
  • Size of the installation directories

For example, assume an RSCD agent installer for UNIX is 150 MB. You start the installation process by copying the installer file to the target host. When you run the installer, it extracts the files it needs and expands them into a file extraction area. The installer then installs files from the extraction area into the actual target system directories. If all of these actions take place on the same disk partition, then the required disk space equals Installer Size + Expanded Size + Installation. The total might be approximately three times the installer size, or 450 MB. 

To reduce space required for installation you can do the following:

  • Set the installer to read from a shared drive.

  • Set the installer to write the expanded files to a temporary area on a different partition, instead of /tmp. Before running the installer, set the INSTALL_FILES_TEMP environment variable. Enter the following commands at the operating system command line:

    INSTALL_FILES_TEMP=<temporaryDirLocation>
    export INSTALL_FILES_TEMP 

    where:
    <temporaryDirLocation> is the location where the installer should expand the installation files.
