How to Point Synergy server to get licenses from multiple Rational License Key Servers

Technote (FAQ)


How do you point your IBM Rational Synergy server to get licenses from more than one IBM Rational License Key Server (RLKS) ?


Unlike other Rational (Telelogic) products, IBM Rational Synergy and IBM Rational Change do not follow the TELELOGIC_LICENSE_FILE environment variable rule when pointing to a different or multiple license servers.


Usually all the Rational (Telelogic) client applications read the value set locally onto the TELELOGIC_LICENSE_FILE environment variable to pull out licenses from the specified hosts.

However Rational Synergy and Rational Change do not follow this rule to point a different or multiple license servers.

  • Until Rational Synergy v 6.5 SP2 - The Synergy server would pickup licenses based on the value that has been set on the license_data.txt in the CCM_HOME/etc directory.
  • Since Rational Synergy v 7.0 - Information about which license server would have to be contacted is available in the system_info.txt file of the CCM_HOME/etc directory.


The content of the license server pointer should have the following format in either way.

For Microsoft Windows servers:


For UNIX servers:


The difference between the 2 environments is the delimiter: Microsoft Windows uses ";" as the delimiter, while UNIX required ":".
