Here are few recommendation that you can make use while setting up the RMS License Manager:
- The computers on which
License Managers run should use static IP addresses rather than dynamically
allocated IP addresses (DHCP).
In fact, redundant License Manager computers must use static IP addresses (see also: Requirements and Recommendations for Setting Up Redundant License Managers).
- The RMS License Manager supports UDP (User Datagram Protocol) that can support both IPv4 and IPv6 addresses. That is, a client can contact the License Manager using the IPv4 or IPv6 communication protocol. When the License Manager is hosted on a dual stack system, both IPv4 and IPv6 clients can communicate with it, however, not all combinations are supported (see the illustration below for more information):
-
IPv4 |
Supported |
Not supported |
IPv6 |

Dual stack |

- Client computers should
directly contact the License Manager that services the licenses used by
that client. The LSHOST
and LSFORCEHOST environment variables or the lshost file can be used
to do this.
- Client computers should
contain a 'hosts' file that maps IP addresses to the host names of the computers
on which License Managers runs; this speeds up contacting those License Managers.
- For certain supported versions of Windows, this file is probably located in <rootdir>:\Windows\system32\drivers\etc The file itself
contains instructions on entry format.
- On UNIX, this file is probably located in the /etc directory.
The License Manager can communicate over a single IP address only on a multi-home PC.
You do not have choice to specify any particular IP address for use by
the License Manager. If the IP address to which License Manager is bound
becomes unavailable for any reason, then the License Manager needs to be
restarted to allow using any other IP address on the system.
- For successful communication between network clients and the License Manager:
- The MTU value should be set to 1474 or above.
- For larger packets having size larger than MTU size, packet fragmentation should be allowed.
- If you experience communication problems, you may diagnose your network using the following command:
- Restart the License Manager in the case of time zone change.
