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:

http://www.rocketsoftware.com

The following Linux packages and their respective dependencies are required:

Redhat and CentOS 5.3 - 5.X

glibc-devel.i686

ncurses-devel.i686

curl-devel.i686

libgcc.i686

gcc

pam-devel.i686

Redhat and CentOS 6.X

glibc-devel.i686

ncurses-devel.i686

libgcc.i686

gcc

pam-devel.i686

libuuid.i686

openssl098e.i686

hal-libs.i686

libidn.i686

If the Linux system has an active Internet connection, then the D3_setup procedure will install these dependencies automatically.

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 which is available from: 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.

 

OpenSSL Libraries

The opensssl package is required if you intend to use the data encryption, SSL or Host Authentication features. If OpenSSL is not already installed, you must re-run the D3_setup command after installing the libraries to create an explicit link to the libraries. See Running D3_setup for more information.

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.
