Set-up before Installation

This document assumes that the Windows platform is fully configured, and that the installing user is a member of the Administrator's group.

Important Note:

Please review these Installation Guide notes carefully before you attempt any installation or upgrades. If you are in any doubt contact your support representative or Northgate directly.

Always make notes covering exactly what you do, step by step, during an installation or upgrade.

If you find any issues with guidance, or ways to improve it, please feed this back by using the "Comment on this topic" links in the Online Documentation. This will help all Reality users with future upgrades.

Note: When Reality is installed on a host that is part of a Domain, a user-id Reality User is installed in the Domain User List. If the host is then moved, or made standalone, Reality will fail to start because it no longer has a default Reality User id to use. To make sure that this problem does not occur, run the command ntinstall from within the Realman folder.

Telnet daemons that have been configured from Windows or using third party software will either need to be reconfigured to use a different port or the Reality default telnet port (23) will need to be changed. Refer to the section netadmin Utility.
The temporary folder referenced by the system environment variable TEMP must exist.
If you intend installing the demonstration/evaluation version of Reality on Windows 7, you will need to enable the Windows Telnet client, as follows:
1. In the Windows Control Panel select Programs and Features. Then select Turn Windows features on or off.
2. Scroll down to the Telnet Client option and enable it by ticking the associated check box.

Disk Layout

For optimum performance the system swap device and the Reality database should be on different physical hard disks.

If Transaction Logging is to be used then the transaction log files should be on a third hard disk.
If possible the tape drives should be on a different SCSI controller to the database disks.
The paging file should be at least twice as big as memory.
By convention the Reality databases reside in a \real0 folder in the root folder of a specified disk drive, where this is a physical or logical drive. This is not mandatory, but will aid support. The \real0 folder needs to be created prior to creating the database(s).

Note: For very large databases it is recommended that you create a partition database using standard host files on different spindles (see Types of Database for details). Alternatively, you can use the Windows Disk Administrator to create a striped set across several hard disks and create the database on this.
