Installing a Failover Server

TotalView's FNE license technology supports a failover license server configuration to provide a robust license server availability solution. This creates a primary/failover FNE license server pair for a complete FNE failover setup/configuration.

The procedure to install a failover license server is the same as installing a regular license server, with a few small differences:

1. Install the FNE Server

For Step 3, the provided configure script is Configure_Backup_Server rather than Configure_License:

cd /opt/toolworks/flexnetls-<version>

sudo bin/Configure_Backup_Server

NOTE: The primary and failover servers must have the same assigned port.

2. Generate a Host ID for Each License Server

For a proper failover setup, you must generate a host ID for both the primary and failover license servers.

3.Configure Hosts to Use the FNE failover setup.

In the case of a failover setup, the TV_LICENSE_FILE environment variable points to the failover host pair using the format <port>@<primarylicserver>:<backuplicserver>, for example:

TV_LICENSE_FILE=7137@licserver:failoverserver

export TV_LICENSE_FILE
