## Administrator Status

The account under which the installation is performed must have administrator rights.

## Installation Directory

During the installation, you are asked to specify an installation directory in which to install your Software GmbH products. By default, the name of the main installation directory is C:\SoftwareAG.

The directory name should not contain embedded spaces. For further information, see Using the Software AG Installer.

The default Start Menu Group is Software AG.

## Side-by-Side Installations

You can install the same Adabas version more than once on the same machine. And you can also install several different versions of Adabas on the same machine. Each version, however, must be installed in a separate directory. You cannot overwrite an existing version, you can only uninstall it.

Choose for instance C:\SoftwareAG\Suite1 for the first installation and C:\SoftwareAG\Suite2 for the second one. Accordingly, the related Start Menu Groups should be named Software AG and Software AG2.

If several Adabas versions are installed on the same machine, it is recommended to install any other Software GmbH products using Adabas into the directory where the specific Adabas version had been installed.

Adabas requires that every Adabas installation is licensed separately. The Adabas license has to be activated for each installation directory. For further information see Final Installation Steps.

### Activate/Deactivate an Adabas Installation

In a Windows environment in which multiple Adabas installations of the same version exist, only one installation can be active. In order to switch to another installation, the previous installation must first be deactivated and the current installation activated.

Activating an Adabas Server installation registers and starts the Adabas services for the current installation.

Deactivating an Adabas Server installation deregisters and stops the Adabas services for the previous installation.

To activate an Adabas installation

1. Activate the current installation via the Start menu under: All Programs> installation_menu_group> Administration> Adabas 7.1> Activate Installation.

To deactivate an Adabas installation

1. Deactivate the previous installation via the Start menu under: All Programs> installation_menu_group> Administration> Adabas 7.1> Deactivate Installation.

## Adabas Data Directory

Adabas stores its configuration data and information about the available databases in a directory identifed by the environment variable ADADATADIR. In particular, if you use Adabas Extended Operations or the Adabas Manager, the descriptions of all databases to be accessed must be stored in ADADATADIR.

The database IDs used must be unique on the same machine. Moreover, the file ADABAS.INI located in %ADADATADIR%\etc contains setup data that should be unique on your machine as well.

ADADATADIR is by default the Program Data directory: %PROGRAMDATA%\Software AG\Adabas .

You can change the value of ADADATADIR for the current installation by running change_adadatadir.bat from an appropriate DOS command prompt. For further information, refer to the section ADADATADIR in the Upgrade Guide in this section.

## Windows User Group

The Adabas installation creates a local Windows user group with the name "SAG Adabas Administrators". The user "EVERYONE" is assigned to this user group by default.

When the Windows user group "SAG Adabas Administrators" is created, you have to reboot your machine when the installation finishes. When this user group has already been created (due to a previous installation), this reboot is not required.

The user group "SAG Adabas Administrators" receives full write permissions for the Adabas Data Directory. Due to the user "EVERYONE", all users have write permissions for the Adabas Data Directory You can limit these permissions by removing the user "EVERYONE" from the user group "SAG Adabas Administrators", and then manually adding all required users to this group. To do so, go to Control Panel > System and Security > Administrative Tools > Computer Management; in the resulting window, select Local Users and Groups.

## Canceling the Installation

As you move through the wizard, the installer stores some of the files it requires in a temporary directory. If you cancel the installer and later restart it on the same machine, the installer will use the stored files rather than downloading them from the installer server again, to improve performance. After a successful installation, the installer deletes the stored files.

If you cancel the installation before it has finished and if you want to remove already installed files, you have to do this manually. For further information, see Uninstalling Adabas.

## Adabas Client Environment

The Adabas Client environment will be automatically set as a global environment, unless another environment is already set as a global environment and the version of this environment is higher than or equal to the version to be installed.

## Mandatory Environment Variable for Adabas Utilities

The environment variables ADADATADIR and ADAPROGDIR are mandatory environment variables which must be defined for Adabas utilities. If either one or both is undefined, this will result in failure and Adabas utilities execution will end. Both environment variables ADADATADIR and ADAPROGDIR have a default value defined.
