As part of a failover plan or a load-balancing system, you may have multiple license servers running the same Replication Server license configuration, using redundant licenses across all servers. The redundant license servers can be connected by LAN or by WAN.
Configuring redundant license servers
Follow the instructions in this guide to install the Replication Server components on each of the servers in the redundant system.
As you install the software, make a note of the machine names and the dedicated port number that SySAM uses on each machine.
After the installation is completed, set the environment variable LM_LICENSE_FILE for each server in the redundant system to:
"port@machine:port@machine:port@machine"
For example, if you use port 2972 on each machine and the machine names are Huey, Dewey, and Louie, the environment variable that points to the license file would look like this:
LM_LICENSE_FILE="2972@huey:2972@dewey:2972@louie"
The first server in the license list is the first server queued by the licensing software.
