This section contains information about installing and creating an environment configuration for InfoHub.

Ensure that you have a correctly configured installation of the following software:


Minimum Version



V6.0-002 or above

InfoHub requires a correctly installed distribution for GT.M V6.0-002 or above. For information on installing GT.M, refer to "Installing GT.M" chapter of the UNIX Administration and Operations Guide.



InfoHub requires a correctly built gtmposix plugin.

Infohub uses the gtmposix plugin to access POSIX functions available on POSIX platforms (UNIX/Linux). For more information on installing the gtmposix plugin, refer to readme.txt available in the gtmposix distribution available on

Your InfoHub distribution comes with three Bourne shell environment setup scripts that automatically define InfoHub environment variables and display the commands to create an InfoHub database and a global directory if they do not already exist. These scripts are designed to give you a friendly out-of-the-box InfoHub operations experience. Even though you can perform normal InfoHub operations without using these scripts, it is important to go through these scripts to understand the how to manage environment configuration for InfoHub. These scripts are as follows:

To use these environment setup scripts, perform the following steps:

To perform any InfoHub operation without using the infohub_*.sh scripts, at a bare minimum, you need to set the following environment variables:

If you are not using the InfoHub environment setup scripts provided with your InfoHub distribution, set the minimum key and record sizes to 1000 and 4000 respectively and block size to 4096 for the global directory for your InfoHub database. The InfoHub Bourne shell Environment setup scripts run a GDE command file to automatically set these values for the InfoHub global directory.

For more information on performing InfoHub operations, refer to Starting an InfoHub, Monitoring (checking) an InfoHub, Restarting an InfoHub, Shutting down an InfoHub, Rundown an InfoHub, Troubleshooting (debugging) an InfoHub, and Purging an InfoHub.

The following table describes some files in your InfoHub distribution. Note that InfoHub Product Routines files are part of the core InfoHub product and the Reference Implementations files are examples using InfoHub. The Uptime and Log File Monitoring Reference Implementation (ULFM) is one of the ready-to-run implementations that monitors the output of the uptime command, operator log, and authentication log requiring any additional configuration.

InfoHub Product Routines
