IBM GC23-7753-05 - Manual (Page 28)

Setting up the installation on the cluster primary node
There must be an existing Informix instance on the computer that has been
configured as documented in “Installing the Informix server on the primary node
of a cluster environment” on page 2-7.
When you run the clusterit_a.exe utility on the primary node, ClusterIT performs
the following tasks:
v Extracts the resource .dll (ifxdb920.dll) to the WINDOWS\cluster directory
v Creates an IBM Informix resource group
v Moves all physical disks on which chunks are located to the IBM Informix group
v Creates a virtual IP address and a virtual host name
v Registers the resource type IFXDB920
v Creates the Informix cluster resource
v Sets dependencies
v Sets the Informix cluster resource to online
To set up a cluster on the primary node:
1.
Run the clusterit_a.exe utility.
2. In the window that opens when you start the utility, fill out the information
about networking environment, machine names, and configuration for the
cluster node:
a.
In the DBSERVERNAME to be clustered text box, enter the name of your
unclustered Informix instance.
b. In the DBSERVERNAME final (when clustered) text box, enter a name for
your Informix instance after it has been converted into a cluster
configuration.
c. In the Physical hostname primary node text box, enter the physical host
name of the primary node.
d. In the Informix password text box, enter your password.
e. Enter the path information in the Full path to the IDS directory on the
Informix RDBMS CD
field.
f. Enter the location of the installation (the value of %INFORMIXDIR% must be
located on a local disk and must be identical for both nodes).
g. In the New virtual host name for the database host text box, enter the new
virtual host name.
h. In the virtual IP address for the database host text box, enter the IP
address for the new virtual host.
i. In the Subnetmask text box, enter the value of the Subnetmask for the new
virtual host.
j. Select the network you want to use for the IP address from the Network
menu.
k. Select the Number of shared disks where you have chunks located.
l. Enter the name of the shared disks you use as chunk locations for Informix
from the Shared disks for database text box. These disks are moved to the
Informix
group that will be created by the ClusterIT utility. In the event of
failure, the disks you specify here will move over to the other node.
3. Click Convert to Cluster. After conversion, an Informix server comes back
online, but it is now controlled by the Microsoft Cluster Service. The resource
group Informix has been created.
