Setting up the Redundant License Server Pool

environment variable and allow the client to broadcast for an available

license server.)

3. If your vendor has specified that the license servers will be locked to

specific computers, you will need to run echoid on each computer and

record the locking code. You should also record the host name of each

computer and its IP or IPX address. You will then give the locking codes,

host names, and addresses to your vendor so that he or she can create the

license codes for these license servers. For information on using echoid,

see “echoid - Get a Computer’s Locking Code” on page 79 of “Chapter

5 - Administrator Commands.”

4. You will now install the protected applications on the end user comput-

ers.

5. If any license servers are running that will be used as redundant license

servers, you must shut them down before creating the redundant license

file.

6. After you receive the license codes from your vendor that will be ser-

viced by the redundant license server pool, use Wrlftool or rlftool (or

WlmAdmin to call Wrlftool) to create a redundant license file to:

• Add the license servers to the redundant license server pool by

specifying the host name and IP or IPX address for each computer

containing a redundant license server. This defines which license

servers are in the redundant license server pool. Note that all license

servers in the pool must use either IP or IPX, but you cannot mix the

protocols.

• Set the preference number of the license servers. The first license

server added to the pool and started up first is also known as the

leader and all other license servers will be known as the followers.

The preference order specifies the order in which the leader will be

chosen if license servers go down.

7. Use rlftool, Wrlftool, or WlmAdmin to add the redundant license codes

received from the vendor into the redundant license file and set their

initial token distribution among the redundant license servers.
