Host Configuration

Each host in your deployment must be configured with the tungsten user, have the SSH key added, and then be configured to ensure the system and directories are ready for the Tungsten services to be installed and configured.

Before configuring the host, ensure you have installed all the required software and configured the network. Detail on these requirements are outlined in the "Requirements" sections.

There are a number of key steps to the configuration process:

• Creating a user environment for the Tungsten service
• Creating the SSH authorization for the user on each host
• Configuring the directories and install locations
• Configuring sudo access to enable the configured user to perform administration commands

important

The operations in the following sections must be performed on each host within your deployment. Failure to perform each step may prevent the installation and deployment of the Tungsten software.

Known Issue affecting Tungsten Clustering

There is a known issue in version 8.0.0 and 8.0.1 that will result in a misconfiguration of the replication services for both new installations and upgrades, under the following conditions:

• Composite Active/Active topology, AND
• Your hostnames contain a dash symbol (-) and/or a mix of UPPER and lower case characters.

All other topologies are unaffected. If the above applies to your installation please use v8.0.2 when available. For any questions or concerns, or if you feel you may already be impacted by this, please contact Continuent Support.
