features. If you cannot configure the selected or cleared features exactly as
you want, it is probably an unsupported installation configuration for your
environment.
Notice that a brief description of a selected component or feature is located
in the GUI window.
Important: If you want to set up clustering for failover support, select
Cluster utility .
5. Optional: Change user authentication settings, depending on your planned
usage of the installation and host environment:
v You can change the user account that runs the Informix database server to a
local system account. Running the Informix server as a local system account
is useful if you are planning to embed the server in an application because
this account is a service that runs as a user without a password requirement.
v If you are installing the server as a local system account and plan to use
Enterprise Replication, create the informix user manually.
v If you are running the installer as a domain administrator and you want to
use a domain account to administrator Informix instances, select Domain.
6. If you are prompted for an Informix administrator password, enter a password
and record it in a secure location. The installation application creates the
administrator account, and you must have the password to administer the
Informix installation. This user account is referred to as user informix
throughout Informix products and documentation.
7. Optional: Enable role separation for auditing procedures.
Important: If you enable role separation, you cannot turn it off after the
product is installed. To remove role separation, you must uninstall the database
server and reinstall it without role separation. To learn more about role
separation, see “Plan role separation” on page 1-3 and click Help in the role
separation window of the installation application.
8. Optional: If you want to set up a ready-to-use Informix instance as part of the
installation, select the Create a server instance option. If you want the server
instance to initialize at creation, click Initialize server. You can either accept
default configuration parameters or customize configuration parameters of the
instance.
Tip: Click Help in this window of the installation application for information
about selecting a default or customized configuration and for information about
the configuration parameters if you select to customize the instance.
If you do not select the Create a server instance option, you can configure and
initialize the database server manually after installation is complete to create a
running Informix instance.
9. Verify that the installation summary accurately reflects your installation
options, and that the host computer has enough free space for the total
installation. Go back to adjust the installation options as necessary.
Important: See “Configuring Informix manually” on page 3-7 to set up an
Informix instance if you did not create a server instance in the installation
application.
