7. Uninstall any previous IDS installations on the secondary node.
Implementing a Cluster on the Primary Node
When you run the clusterIT_a utility on the primary node, ClusterIT performs the
following tasks:
v Extracts the resource .dll (ifxdb920.dll)totheWINDOWS\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 IDS cluster resource
v Sets dependencies
v Sets the IDS cluster resource to online
To use ClusterIT to implement a cluster, the INFORMIXDIR directory must be
located on a local disk, the (INFORMIXDIR directory must be on an identical local
path for each node, and any chunks must be on shared disks. It must be possible
to move the disks from one node to another.
IDS as a Cluster on the Secondary Node
When you run the clusterIT_b utility on the secondary node, the clusterIT_b
utility performs the following tasks:
v Installs IBM Informix Dynamic Server on the secondary node (silent installation)
v Copies registry entries from the primary node
v Copies the ONCONFIG file from the primary node
v Makes the resource .dll (ifxdb920.dll) available on the secondary node
Installing IDS as a Cluster on the Secondary Node
To install IBM Informix Dynamic Server in a cluster configuration on the secondary
node:
1. Run the following command on the secondary node: clusterIT_b The IBM
Informix ClusterIT - secondary node window appears.
2. Fill in the text boxes:
a. In the Physical hostname primary node field, enter the physical host name
of the primary node.
b. Fill in the Full path to the IDS directory on the Informix RDBMS CD
field.
c. Enter the Instance number that you choose for IDS on the secondary node.
This number is the same as that of IDS on the first node.
d. Enter the location of the installation (the value of %INFORMIXDIR%,
which must be located on a local disk and must be identical for both
nodes).
e. Enter your Informix password.
f. In the DBSERVERNAME final (when clustered) text box, enter the name of
the IDS instance in the cluster configuration. On this secondary node, IDS
will be installed directly with this name.
g. Check whether or not to enable Role separation. For more information, see
“Planning Role Separation” on page 1-8.
