IBM GC23-7753-05 manual User informix, Upgrading the Database Server, Local Installation

Local Installation

If you do not plan to have workstations access a domain controller, install the database server on a local computer. For a local installation, you should have administrative privileges.

Domain Installation with Domain Administrator Privileges

Domain installation is useful if you run the database server on several computers and want a central security mechanism. If several of your computers belong to the same domain, and therefore share the same primary domain controller or domain controllers, perform a domain installation on these computers. To install in a domain, you must have administrative privileges and your computer must already belong to a domain. Run the installation program and choose the Install in Domain option when the installation wizard prompts you.

User informix

User informix is a user account with main authority over an IBM Informix

Dynamic Server instance.

User informix is required for most installations because it has the unique user

identifier (UID) to manage and maintain IDS instances and databases on the host

server. The only exception to this requirement is when you install IDS 11.50 as

local system user.

The password for this user account must be protected. Only let trusted database

and security administrators log in as user informix.

If you are installing IDS for the first time on your system and have not selected the

local system user option, the installation program prompts you to create the

informix user by providing a password. If user informix already exists on your

system, the installation program prompts you to confirm the password.

Important: The database server will not start if password standards for either

user informix or end users do not conform to local security standards.

Upgrading the Database Server

For information on migrating your database server from a previous version of IBM

Informix Dynamic Server to Version 11.50, and for information on migrating your

data, see the IBM Informix Migration Guide, Version 11.50.
