Before you install the license server on redundant UNIX system servers

Download and install license keys.

To set up the license server software on redundant UNIX® system servers, you must have the licensing executables from the IBM Rational® download site and a license key file for redundant UNIX system servers from License Key Center. Then configure a start script and start each server.

The license_setup script cannot import license key files for redundant servers, and it cannot start redundant servers. Instead, you must manually install the license file and server software on each computer.

Here are the requirements for setting up redundant servers:
  • If you have already set up a license server and want to use that server in the redundant server configuration, remove the IBM Rational License Server software from the computer. See Removing the Rational License Server software from UNIX systems.
    1. Return the license keys to License Key Center (Moving or removing license keys on a UNIX system server).
    2. Follow instructions for installing the license server and license keys in a redundant server configuration.
  • Request the license key file for redundant UNIX system servers. Go to License Key Center and request a license for redundant servers. License Key Center will ask you for the primary, secondary and backup servers. Be sure to specify the redundant servers in the correct order:
    • Host ID is the primary server
    • Host Name 2 is the secondary server
    • Host Name 3 is the backup server
  • If you have problems receiving or working with the redundant server license file, contact IBM Software Support for Rational products.
  • The license server can be installed on all of the UNIX system platforms that Rational supports.
  • There is no minimum processor, memory, or disk space.
  • License Key Center sends the license file to an e-mail account when you request a license. It has the file name format similar to license_for_server.upd.
  • To check the connection between the servers and clients, use the following UNIX system commands: ping, arp, rsh, rlogin, or telnet.
  • The servers should be on the same subnet.
  • The license server software must be installed locally. Each server uses a FLEXlm lmgrd process and a rational daemon process to manage licenses. For more information about these processes, see Understanding IBM Rational Common Licensing components.
  • You must manually install the license server software on the servers.
