4. Click Convert to Cluster. After the ClusterIT utility finishes conversion, the
Informix instance tarts on the secondary node.
Important: The silent_install_11.70.ini and cluster.ini files contain your
passwords for administering the Informix installation. After you have completed
the clustering environment setup, edit these two .ini files on both the primary
and secondary nodes to remove the passwords. Alternatively, you can delete the
silent_install_11.70.ini
file and the cluster.ini file.
Multiple residency
You can set up multiple independent database server environments on the same
computer.
Complete the following tasks to set up multiple residency.
Plan for multiple residency
When you plan for multiple residency on a computer, consider the following
factors:
v Storage space
Each database server must have its own unique storage space. You cannot use
the same disk space for more than one instance of a database server. When you
prepare an additional database server, you must repeat some of the planning
that you did to install the first database server. For example, you must consider
these questions:
– Will you use mirroring? Where will the mirrors reside?
– Where will the message log reside?
– Can you dedicate a tape drive to this database server for its logical logs?
– What kind of backups will you perform?
v Memory
Each database server has its own memory. Can your computer handle the
memory usage that an additional database server requires?
Creating a new database server instance
Before you set up multiple residency, you must install one database server as
described in Chapter 2, “Installing Informix and client products on Windows,” on
page 2-1. It is not necessary to install more than one copy of the database server
binary files. All instances of the same version of the database server on one
computer can share the same executable files.
To set up multiple residency, use the Server Instance Manager. To use the Server
Instance Manager program, you must have administrative privileges on the
database server. However, local administrator privileges are sufficient, even if the
database server was installed for domain use.
Before you use the Server Instance Manager, verify that you are a member of the
Informix-Admin
group. For more information, see “Verify Administrators group
membership” on page 1-2.
The following steps are for using the Server Instance Manager GUI. See “Server
Instance Manager command-line options” on page 2-11 for other ways you can use
this utility.
