Setting up the Redundant License Manager Pool

Each License Manager runs on a separate computer on the network. Follow the steps given below to create a redundant License Manager setup:

  1. First, install (but don’t run) the License Managers on different computers on the network.

If any License Managers are running that will be used as redundant License Managers, you must shut them down before creating the redundant license file.

  1. Use rlftool or WRlfTool to add the redundant license codes received from the vendor into the redundant license file (by default named as, lservrlf).

Tip:

By using the lslic utility, redundant licenses can be added dynamically. If the requested License Manager is a follower, it will forward the request to the leader; the leader License Manager will then check the validity of license. If the license can be added, the leader will add that license and forward the license code to all the followers.

  1. Since this is the first time that the redundant License Manager pool has been set up, you need to copy the redundant license file to each of the computers on which the redundant License Managers resides. After this, changes to any one of the redundant license files will automatically be transmitted to each redundant License Manager when one of the License Managers is stopped and restarted.
  2. Do not create a “mixed” redundant License Manager pool—a one that consists of both isolated License Managers (of the same vendor) and generic License Managers. Instead, you can create a pool consisting of either isolated License Managers or generic License Managers.

  3. Bring up each of the License Managers in the pool. Because the redundant license file is in the same directory as each License Manager, each License Manager will automatically start up as a redundant License Manager.
