Installation of the HULFT Clustering function

In order to use the HULFT Clustering function, install HULFT in both the ACTIVE server and the STANDBY server.

Installation procedures vary depending on the type of installation.

To install HULFT on the ACTIVE node, install the execution module (HULEXEP) in the local disk and install the environment settings files (HULPATH) in the shared disk that is being mounted.

When installing HULFT on the STANDBY node, install only the execution module. For shared disks that are not mounted, do not install the environment settings files.

 

Install HULFT in each node using the HULFT installer by following the three types of installation procedures.

This explanation of the operation configuration uses the unidirectional standby configuration as an example. The unidirectional standby configuration requires one installation per node, whereas the bidirectional standby configuration requires one installation per HULFT to be run.

For details on the installation method, refer to Installation Manual.

(1) New Installation Procedure

This section explains the procedure for a new installation of the HULFT Clustering function.

This procedure is applicable to the installation of the following products:

  • Trial version

  • Product version

  • Product version (Fixed Term License)

 

The installation procedure is as follows:

Figure 3.4 New Installation Procedure

1) Perform New Installation of HULFT on the ACTIVE node.

2) Perform New Installation of HULFT on the STANDBY node.

(2) Standard Update Installation Procedure

This section explains the procedure for stopping HULFT (daemon) and installing HULFT in the inherited environment.

This procedure is applicable for the following case:

  • Version upgrade from HULFT that does not have the clustering function

 

The installation procedure is as follows:

Figure 3.5 Standard Update Installation Procedure

1) Stop the currently-running HULFT.

2) Perform Update Installation of HULFT on the ACTIVE node.

3) Perform Update Installation of HULFT on the STANDBY node.

(3) Procedure for updating the cluster license

This section explains the procedure for installing HULFT and inheriting the existing environment without stopping the currently operating HULFT (daemon).

This procedure is applicable for the following case:

  • License update

 

The installation procedure is as follows:

Figure 3.6 Procedure for Updating Cluster Licenses

1) Update the license for the HULFT that is installed on the STANDBY node (or the node that is not mounted to the shared disk).

2) Switch over to the other node.

3) Update the license of the HULFT that is installed on the STANDBY node from which you switched. Then return the node to its original state.
