The PSQL v12 database engine license can be installed to ONE
server at a time. While you can migrate a license from one server to
another by deactivating it first, if the first server fails, you may not
be able to bring up a new server to replace it in a timely manner.
Instead of purchasing a complete license for the second server that may
never be used, PSQL Insurance may be a much better option. This product
contains a special license key that allows you to bring up a temporary
server for a period of 7 days on three separate occasions. This gets
your database environment up and running immediately, giving you time to
either fix the primary server or contact Pervasive and move the license
permanently to the new box.
PSQL v12 Insurance licenses will work on either platform (Windows or
Linux) or bit level (32-bit or 64-bit), and you can switch platforms
and bit levels at any time. The only user counts available are 50-User and 250-User.
