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:
vExtracts the resource .dll (ifxdb920.dll) to the WINDOWS\Cluster directory
vCreates an IBM Informix resource group
vMoves all physical disks on which chunks are located to the IBM Informix group
vCreates a virtual IP address and a virtual host name
vRegisters the resource type IFXDB920
vCreates the IDS cluster resource
vSets dependencies
vSets 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:
vInstalls IBM Informix Dynamic Server on the secondary node (silent installation)
vCopies registry entries from the primary node
vCopies the ONCONFIG file from the primary node
vMakes 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
