Preparing to install CICS Transaction Gateway

Various tasks must be completed before installing CICS® Transaction Gateway.

  1. Check that your operating system is supported; for more information see Operating systems.
  2. Only one of the products CICS Transaction Gateway for Multiplatforms, CICS Transaction Gateway Desktop Edition, or CICS Universal Client can be installed on an operating system at a time. Any version of one of these products must be uninstalled before you install a version of another one of these products.
  3. Product upgrade support is as follows:
    • CICS Transaction Gateway for Multiplatforms can be upgraded from V7.0 or later; earlier and beta versions must be uninstalled first.
    • CICS Transaction Gateway Desktop Edition can be upgraded from V8.0 or later.
  4. When a CICS Transaction Gateway installer is named with a version string that includes a fix pack number then that installer includes all the product updates supplied by that fix pack. For more information about version strings see Product versions.

Windows platforms

The installation requires approximately 240 MB of disk space after the install process finishes. Additional space is required for log and trace data. To successfully complete an installation ensure that additional temporary disk space is available; 460 MB is required for a new installation and 690 MB is required for an upgrade installation.

To prepare to install CICS Transaction Gateway:

  1. Log on with administrator privileges. Administrator authority is required for installing and uninstalling. Administrator privileges are available if you are a member of the local Administrators group or if you are a domain Administrator.
  2. Check that there is sufficient free disk space.
  3. If you are upgrading, stop any CICS Transaction Gateway application processes, product processes or services that are running, for example the IBM CICS Transaction Gateway service and the Configuration Tool.
  4. When using Windows Server Remote Desktop Services, ensure that your session is correctly configured to install new software. Take one of the following steps:
    • Install from Add or Remove Programs on the Control Panel.
    • At a command prompt, type change user /install to place the system into install mode. When the installation has finished, type change user /execute at the command prompt to return the system to execute mode.

UNIX and Linux platforms

The installation requires approximately 260 MB of disk space for Solaris, 220 MB of disk space for AIX, 200 MB of disk space for Linux, and 350 MB of disk space for HP, after the install process finishes. Additional space is required for log and trace data. To successfully complete an installation ensure that additional temporary disk space is available; 460 MB is required for a new installation and 690 MB is required for an upgrade installation.

To prepare to install CICS Transaction Gateway:

  1. Log on as root.
  2. Check that there is sufficient free disk space.
  3. If you are upgrading, stop any CICS Transaction Gateway application processes, product processes or services that are running, for example the Gateway daemon, the Client daemon and the Configuration Tool.
  4. Check the root user's umask to ensure that files created during the installation are readable by the user IDs that run CICS Transaction Gateway. A umask of 077 restricts access to the root user that installed CICS Transaction Gateway; a umask of 022 allows all users to run CICS Transaction Gateway.
  5. By default, the installer uses the /tmp directory for temporary data, or /root if there is insufficient space in /tmp. You can override this behavior by setting the IATEMPDIR environment variable to the required temporary directory before launching the installer.
