Upgrading to Host Integrator 6.6 in a Linux/UNIX Environment
Technical Note 40030
Last Reviewed 11-Sep-2008
Applies To
Verastream Host Integrator version 6.6
Summary

This technical note provides detailed steps to upgrade Verastream Host Integrator to version 6.6 in a Linux/UNIX environment. The upgrade process includes backing up files, removing the existing installation, installing version 6.6, and migrating the existing configurations and host application models.

See Technical Note 10080 for a list of new features in version 6.6; Technical Note 10069 for version 6.5; and Technical Note 10061 for version 6.0.

Overview

In the Linux/UNIX environment, upgrading Host Integrator requires these steps.

The procedure below assumes the following.

• All Host Integrator components are installed on the same Linux/UNIX machine.
• The Authentication, Administration, and Directory Services (AADS) is not linked to any other Host Integrator servers. (For example, you are not using Session Server load balancing as described in Technical Note 10052.)
• The models can be migrated first and upgraded in the Design Tool at a later time. (For more information on updating models, see Technical Note 40023.)
• Although you can install the Host Integrator files to a directory of your choice, the steps assume an install directory of /usr/vhi.

I. Back up the existing files

1. Log in as root on your Linux/UNIX machine.
2. Copy the /usr/vhi/etc directory to a temporary directory. (In this example, the temporary directory is /tmp/vhi.)

3. If you are upgrading an Administrative WebStation, look for the console.install file in /usr/vhi/lib/java. This file exists only if the Administrative WebStation was run locally in a browser on the machine where the Host Integrator server is installed. If console.install is present, then copy it to the temporary directory. For example:

4. Copy the deploy directory, /usr/vhi/deploy, to a location outside of the existing Host Integrator installation directory, such as the following:

5. Before you uninstall the existing Host Integrator components, make a note of the current settings:

• Host Integrator domain server settings
• LDAP settings (Note: LDAP settings cannot be migrated; you will need to restore these after the upgrade.)
• Security: enabled/disabled

II. Remove the existing installation

Run the Verastream Host Integrator 6.6 setup command as shown below to uninstall Host Integrator. Answer Yes when you are prompted to remove the existing Verastream Host Integrator Installation.

III. Install all Host Integrator 6.6 components except the Session Server

When upgrading in the Linux/UNIX environment, the AADS must be installed and the AADS settings migrated before the Host Integrator server is installed.

1. Install version 6.6 into the same directory where the previous version was installed. This technical note assumes /usr/vhi.
2. Use the command below to install all components except the server.

aads	AADS server
apicpp	AppConn Connector for C
apijava	AppConn Connector for Java
help	Product Help
hostemul	Host Emulator
logutils	Log Viewer and Export Utility
smonitor	Session Monitor
webstation	Administrative WebStation

3. Accept the defaults and proceed with the installation. When prompted, do not start the AADS.
4. When Setup is complete, confirm that all of the components are stopped:

IV. Migrate the AADS settings

To preserve the AADS configuration, copy the saved files that you created above into the new installation directory.

Note: Some of these files may not exist in your installation.

V. Install the Host Integrator Session Server

1. Start AADS before installing the server:

2. To install the Verastream Host Integrator 6.6 server, use this command:

3. Do not start the server when prompted. If the server starts before the model files are migrated, errors will be logged.
4. Restore the session server configuration file:

5. If you did not install an Administrative WebStation, skip to VII. Migrate the deployment directory.

VI. Migrate the Administrative WebStation

1. Restore the Administrative WebStation configuration file:

2. Start the Administrative WebStation:

VII. Migrate the deployment directory

Restore the deployment directory:

VIII. Start all components and verify the upgrade

1. Use this command to start all components, including the Host Integrator server:

2. At this point, the Host Integrator Server recognizes the original model file/directory structure and upgrades the models in the 6.6 deploy directory.
3. Open the Administrative WebStation.

4. Confirm that your models are activated and confirm or restore the settings that you noted earlier in this process (section I. above):

• Host Integrator domain server settings
• LDAP authentication settings
• Security: enabled or disabled

IX. Update Session Monitor Directory Server

As of version 5.5, the Session Monitor creates a default security certificate when connecting. This certificate may still be present after uninstalling the previous version of Host Integrator and reinstalling the new version. After the upgrade, the Session Monitor will attempt to use a certificate that is now out of date. When attempting to connect, you'll see messages such as "SSL connection failed. Certificates don't match." To correct this problem, select Remove Directory Server from the Configure menu. You can ignore additional error messages while doing this operation. Next, select Add Directory Server to add it again with an appropriate security certificate.
