IBM GC23-7753-05 - Manual (Page 27)

v Copy the cluster.ini, clusterit_b.exe, and silent_install_11.70.ini files
from %INFORMIXDIR% of the primary node to the directory where you want to
install the database server on the secondary node. These .ini files are in
%INFORMIXDIR%
of the primary node as a result of the Informix server
installation there.
v On the secondary node, run the clusterIT_b.exe utility. The utility installs the
Informix server and configures the primary node's database server instance
to run with the instance on the secondary node.
Installing the Informix server on the primary node of a cluster
environment
Before you install the server, do the following:
v Decide on an %INFORMIXDIR% path that is a local disk and is the same path on
both the computer with the primary node and the computer with the secondary
node.
v Verify that the shared disks of the cluster can store all chunks. All chunks must
be on shared disks.
After the installations on both primary and secondary nodes, it must be possible to
move the disks from one node to another. While all chunks must be on shared
disks, each %INFORMIXDIR% must be local to each node.
To install the Informix database server on the host computer of a primary node for
the cluster environment:
1.
Install the Informix server with the following configuration:
a.
Select Custom setup in the installation application.
b. In the Product Selection window that contains the product and feature tree,
select the Cluster utility feature of the core database server family.
c. Specify a domain user informix account.
d. Select the Create a server instance checkbox, and verify that the Initialize
server
checkbox is not selected.
See “Installing with the GUI custom setup” on page 2-2 for more information
about custom installation.
2. Edit the onconfig file. For more information about the onconfig file, see the
IBM Informix Administrator's Reference.
3. Put the root dbspace on a shared disk.
4. Move all shared disks to the primary node.
5. Initialize the database server. For more information, see “Database server
configuration after installation” on page 3-5.
6. Create additional dbspaces, if necessary. For more information, see “Dbspace
name, location, and size” on page 3-6. Additional dbspaces must be located on
shared disks.
To complete the cluster setup on the primary node, see “Setting up the installation
on the cluster primary node” on page 2-8.
