licensing offers two forms of server redundancy to guard against license
disruptions: redundant license server triads and license file lists.
A redundant license server triad consists of three license
servers that function as one using the same license key. A license file list
consists of multiple independent license servers, each with its own license
key; token requests will check each license server in the list until available
tokens are found. For a detailed comparison of the two redundancy
configurations, see “Comparing multiple license servers to three-server
redundancy” in
the Dassault Systèmes Knowledge Base at www.3ds.com/support/knowledge-base.
Configuration of license file lists is not covered in detail in this guide.
A redundant license server triad requires three computers. At least two
license servers must be running for licenses to be granted. Network
communications must be consistent and reliable among the three computers used
in a redundant server triad. Redundant license server triads are considered to
be an advanced use of
FLEXnet Licensing.
More detailed requirements for redundant license servers appear in the
FLEXnet Licensing
End User Guide Version 11.6, which is available for download from the
Licensing section of the Support page
at
www.3ds.com/simulia.
You can install and configure a redundant
FLEXnet
license server triad using either an automatic or a manual process. The manual
process is required if your servers use different port numbers; otherwise, the
automatic installation is recommended. In both cases you will have to start the
servers manually using the
FLEXnet
license server manager lmgrd. In their initial startup, the
redundant license servers must be started simultaneously (within one minute of
each other).
