Installation prerequisites

Before you start the installation, you must fulfill these requirements:
  • You need to have root authority to install System Automation for Multiplatforms on the system.
  • A Korn shell must be installed on all OS platforms except the RHEL and SUSE OS platforms where a MirBSD Korn Shell (mksh) must be installed.
  • Perl is required to use the command-line interface of System Automation for Multiplatforms including native RSCT commands. The command-line interface is installed by default on your Linux® or AIX® systems as part of the operating system. If you are using System Automation for Multiplatforms in a language other than English, a special version of Perl might be required. Due to known problems with Perl 5.8.0 and how it handles UTF-8 encoded locales, some characters might not be properly displayed. The problem can occur on systems with Perl 5.8.0 is installed, if you use a UTF-8 encoded locale. When previous or subsequent versions of Perl are used, or non-UTF-8 encoded locales are used, this problem does not occur.

    If you decide to upgrade your Perl 5.8.0 version on a Linux distribution, process the following steps:

    1. Download the Perl 5.8.1 source.

    2. Extract the file on any directory by using -xvf.

    3. Compile and install on the UTF-8 system, referring to the instructions provided with the downloaded files.

    4. Change the symbolic link, which is pointing to the directory of the Perl version that is used by System Automation for Multiplatforms

      Change link from:

      /usr/sbin/rsct/perl5/bin/perl->/usr/bin/perl
      To the directory where the new version of Perl is installed: 
      /usr/sbin/rsct/perl5/bin/perl->/usr/local/bin/perl

  • Make sure that the directories /usr/sbin and /opt have at least 100 MB free space, and that the directory /var also provides at least 100 MB free space.

  • On any node where the end-to-end automation adapter is configured to run, at least 128 MB RAM must be available.

  • During installation of System Automation for Multiplatforms on AIX, the levels of RSCT packages that are required by System Automation for Multiplatforms are checked against the levels of RSCT packages already installed with the operating system. Missing packages or higher levels of RSCT packages are installed if required. Under certain circumstances, you might need to manually install higher levels of certain RSCT packages. For example, if the RSCT basic package is not installed, and the level of the installed RSCT core package is higher than the level of the RSCT packages that are supplied with System Automation for Multiplatforms, the installation of the RSCT basic package might fail due to RSCT prerequisites not being met. You need to download and install the appropriate RSCT file sets from the AIX service center to ensure that all RSCT packages installed are at the same level.

  • For other operating system-specific requirements, see the Software Product Compatibility Reports.

  • For languages that are using the double-byte character set (DBCS), the Telnet dialog buffer must be sufficiently large to ensure that long messages are properly displayed. Otherwise, enlarge the Telnet dialog buffer.

  • In some RHEL distributions, the SELinux environment is turned on by default. Make sure that the SELinux environment is switched off so that System Automation for Multiplatforms works properly.

  • As per SUSE announcement, the support for Korn Shell (Ksh) will become EoS after Q1’22 on SUSE distributions.
