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.
See also “Upgrade of IDS by Overwriting an Existing Installation” on page 2-12 to
replace the earlier product.
