Compatibility and Performance Notes
Compatibility
The RMS License Manager runs as a system service on Windows and as a background process on UNIX.
Being cross platform, clients running different operating systems can obtain licenses from a centralized License Manager.
The license
server 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.
Performance Notes
High performance is always a consideration on a busy network. There
are several things you can do to optimize the speed with which licenses
are acquired by your network users, and to speed up the use of RMS utilities:
- 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.
- 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 reside; this speeds up contacting those license
servers. For certain supported versions of Windows, this file is probably located in \System32\a\Etc. The file itself
contains instructions on entry format.
