Minimum Recommendations and Requirements

Installing and using D3 requires a working knowledge of the underlying UNIX operating system on which D3 will be installed. The minimum hardware and software recommendations and requirements for installing D3 are listed below. Use the information located in the System Administration Guide to assist in determining the best configuration.

Operating System Requirements

Use a Rocket certified version of Linux. Use Red Hat Enterprise Linux (AS/ES/WS) or CentOS (32 or 64 bit) - Intel only. See the Rocket Web site for a list of currently supported distributions at:

www3.rocketsoftware.com/rocketd3/support/statussheet/index.jsp

When installing on 64 bit Red Hat Enterprise Linux editions, the following Linux packages and their respective dependencies are required:

Package	Description
glibc-common	i386/686 or x64 versions.
glibc-devel	Must be the i386/686 version.
glibc - x32	i386/686 and/or x64 versions.
gcc - x64	x64 version.

Hardware Requirements

These hardware requirements are the minimum equipment required to run D3 Linux.

Memory

Minimum required memory is 16 MB and maximum recognized memory is 2.5 GB. If installing on a 64 bit version of Linux, then the maximum recognized memory is 3.5 GB. For more information see the Using D3 Memory section of the D3 System Administration Guide.

Hard Disk Space

WARNING

Not enough swap space on the system can lead to a UNIX system crash. However, too much swap space provides less disk space for other programs.

Hard Disk Space Categories	Linux Minimum Recommendations	Your Actual
File space for the D3 partition	400 MB.
File space for Linux	60 MB or more (depending on system configuration). These Linux package options are further documented in the Red Hat Linux installation guide found on the CD, or on the Internet, at: http://www.redhat.com
Application data space
Considerations for increasing disk space requirements for the D3 file system:
Customer data
D3 application files
Growth space
D3 error log (optional)	10 MB of additional space.
Swap space calculation:
Minimum	32 MB
Maximum	Calculate two times the amount of memory.
Systems with up to and including 128 MB of physical, installed memory.	Estimate the swap size as two times the physical installed memory.
Systems with 129 MB or more of physical installed memory.	Estimate the swap size as equal to the physical installed memory.

Registration

A new registration and license agreement is always required. This includes users who are performing new or upgrade installations. Please take a few moments to fill out and send in the registration card (part of the license agreement) shipped with the D3 software. Registration allows access to customer service representatives and allows Rocket to inform customers of product updates and enhancements.

C Development Environment Must Be Installed

A version of the C Development environment must be installed for D3 Linux to install. The C Development environment can be found on the Red Hat distribution CD.
