Installing and Setting Up Software AG Products on UNIX

This document contains general information which applies when installing and setting up any Software AG product on a UNIX platform. The following topics are covered:


General Information

Installation Package

The installation package containing Software AG products is provided on an installation medium conforming to the ISO 9660 standard.

The installation medium contains a complete directory structure which clearly specifies product and platform.

Software AG Environment

The following figure shows the general directory structure generated during installation and the environment variables which reference the specified directories:

General directory structure

Note:
Product code files (those that do not change after installation) are stored in the version subdirectories. Product data files (those that can change after installation) are stored one level higher up, in the three-character product code directories (such as ada or wcp).

The environment variable $SAG defines the root directory for all Software AG products. It is recommended to define SAG=/opt/softwareag.

For each product, the variable $prodDIR is set to the path of the main directory of the product specified, where prod is a three-letter product code in upper-case letters. For example, all files for Entire Net-Work, whose product code is WCP, are contained in the directory $WCPDIR.

The name of the main directory is usually the same as the product code in lower-case letters. For example, the main directory for Entire Net-Work is named wcp and the main directory for Entire Net-Work Client is named wcl.

Version-independent parts of the product, such as examples or data, are stored in a subdirectory of the product main directory. For example, all Adabas demonstration data is contained in the directory $ADADIR/adademo.

Version-dependent components of the product are kept in the version directory $prodDIR/$prodVERS. For example, the current versions of Entire Net-Work or Entire Net-Work Client is stored in the directory $WCPDIR/$WCPVERS.

The environment variables prodDIR and prodVERS for all products specified during installation are defined via the file sagenv.new. The same applies for any other environment variables needed for the various products.

Before Installing Your Software AG Product

It is recommended that you use /opt/softwareag as one common root directory for all of your Software AG products. For Linux systems, this location is the registered name with LANANA.

The default search path for dependent libraries of some Software AG products is /opt/softwareag. They are loaded from this location or using the environment variable $LD_LIBRARY_PATH ($SHLIB_PATH on HP-UX systems). If you install the product to a different location (for example, /usr/SAG instead of /opt/softwareag), you may create a symbolic link to your $SAG directory to get a valid default search path:

su
cd /opt
ln -s $SAG softwareag

The following activities must be performed if you are installing a Software AG product for the first time, or if your environment is not yet set correctly due to any other causes.

This section covers the following topics:

Creating the Administrator's Account and Group

You must create one administrator account and one group for all Software AG products when you install your first Software AG product.

  1. Define an administrator account to which all of the Software AG products installed at your site belong. Since all environment definition files for the products are written in Bourne shell syntax, the Bourne (or Korn) shell is recommended as the login shell for the administrator account. This section assumes that the administrator account is called "sag".

  2. Define a group to which the administrator belongs. This section assumes that this group is also called "sag".

  3. Create a login directory for the user "sag" (for example, /opt/softwareag).

  4. Make sure that the group "sag" is defined in the system file /etc/group and the user "sag" is defined in the system file /etc/passwd.

Note:
To perform these steps, use an appropriate system administration tool.

Backing Up Your Current Product Version

When upgrading a product, it is strongly recommended that you back up your current product version.

Logging in as User "sag"

This description assumes that the user "sag" is the administrator for Software AG products. It is recommended that you log in as the user "sag".

Installing the Contents of the Installation Medium to Disk

Before performing the following steps, make sure that the administrator user and group have been created and defined.

Start of instruction setTo install the contents of the installation medium to disk

  1. Load the installation medium and mount it if this is not done automatically.

    Command Description
    su - root
    To mount an installation medium you may need to be root.
    mkdir /mount-dir
    You may need to create a mount directory for the installation medium.
    mount platform-specific_mount_options device-name /mount-dir
    Execute the mount command (see the table below for operating system-specific mount commands).
    exit
    Return to "sag" user.

    Platform-specific mount command and options to mount the installation medium as ISO9660 or High-Sierra file system:

    Platform Mount Command
    AIX
    /usr/sbin/mount -F cdfs -o cdcase device-name /mount-dir
    HP-UX
    /usr/sbin/mount -F cdfs -o cdcase device-name /mount-dir
    Solaris
    /usr/sbin/mount -F hsfs -o ro device-name /mount-dir
    Linux
    /bin/mount -t iso9660 -o ro device-name /mount-dir

    Note:
    On Solaris, the volume management daemon vold might be active. This daemon mounts the installation medium automatically.

    Example for Linux:

    /bin/mount -t iso9660 -o ro /dev/cdrom /mnt
  2. Check the directory structure of the UNIX part of the installation medium. When you run an ls(1) command on the installation medium, you will see a structure like the following:

    Installation medium

    Note:
    Depending on the mount options used, the files will be all upper case or all lower case. If you mount the installation medium as a pure ISO 9660 Interchange Level I CD, you will also see a version number ;1 appended to all files. Please note this for the following steps and use the correct name format.

  3. For Linux S/390, a single archive is provided for your convenience (for example, for Entire Net-Work this is the file WCPv732n.tgz). The following steps can be performed after you have loaded the installation medium on a Windows or UNIX machine that has a network connection to the Linux S/390 system:

    1. Copy the archive file (file-name.tgz) that is located in the root directory of the installation medium to a temporary area such as /tmp/cdrom in your Linux S/390 environment, using for example ftp in binary mode.

    2. Unpack the archive using the command tar -xzvf file-name.tgz.

    3. Read the installation instructions for details on how to start the installation from this media in the file setup.txt in this directory. Instructions of how to proceed after installing the software will be displayed at the end of the installation and also copied onto your hard disk.

  4. Please continue reading the step-by-step installation instructions for the Software AG product being installed.
