System Requirements

Dynamic Virtual Machine (DVM) versions that are fully compatible with the Four J's License Manager and those older versions that need to be patched.

Four Js License Manager is ported to all platforms supported by the Four Js DVM. The following DVM versions are fully compatible with the Four Js License Manager:

• BDS version 3.55 and higher

• Genero version 1.32 and higher

Versions older than those specified above need to be patched (or entries in the fglprofile file need to be updated) to be compliant with Four Js License Manager.

Recent versions of the DVM can show the minimum license version required. The License Controller or License Manager will return an appropriate message in case of incompatibility. The minimum license version required should be displayed too.

The Four Js License Manager is supported on the same operating systems as Genero Business Development Language (BDL)

For a list of supported operating systems refer to the topic on supported operating systems in the Genero Business Development Language User Guide.

For a detailed list of supported operating systems, refer to the System Support matrix (available on the Four Js Web site in the product and documentation download area) or contact your support center. This matrix also informs you which operating systems will no longer be supported as of the next release.

Four J's License Manager requires either a UNIX™ or Windows^® machine.

Aside from requiring a host machine, the Four J's License Manager does not require any specific hardware.

Disk space required for Four Js License Manager installation.

1.2 Mb of disk space is required for installation. Once the License Manager is installed, the required disk space is approximately 900 Kb. The actual amount of disk space may vary slightly, depending on the operating system.

Software requirements of Four Js License Manager.

The Four J's License Manager itself does not require any specific software. During the installation phase, however, the installer program calls some system commands (such as df, tar and gzip on UNIX systems). The installation program automatically checks for such prerequisites and raises an error message if a required system command is missing.

In order to license the product online from the Four J's Web site (http://www.4js.com), you need an Internet connection.
