We are evaluating the possibility of using cyrus for a
commercial product.
Therefore, I'm looking licensing issues with Cyrus and the Berkeley DB
product must be licensed if the source code of the product
using it is not provided. The license depends on which
Berkeley DB product you are using.
Does anyone know which of the below Berkeley DB products
cyrus is using?
The four different products are:
+ Berkeley DB Data Store: Intended for single-user, or
multi-user read-only, applications that don't need
transactions or disaster recovery.
+ Berkeley DB Concurrent Data Store: This product allows
multiple users to use the database at the same time,
with any mix of readers and writers. It does not
support transactions or disaster recovery.
+ Berkeley DB Transactional Data Store: This is our
enterprise-class embedded database manager. It supports
arbitrarily many concurrent users, with any mix of readers
and writers. It also supports transactions and recovery
from application, system, or hardware crashes.
+ Berkeley DB High Availability: HA provides single-master
replication with fail-over, and is built on top of the
Berkeley DB TDS product. Using HA, you can run multiple
instances of your application on different servers on a
network. All updates must go to the master server, which
distributes changes to all replica servers. Each of the
replicas can support read queries on the database. If
the master fails for any reason, one of the replicas is
able to take its place, and the application can continue
to run.
Is cyrus dependent on Berkeley DB or fairly easy to remove the
dependency or replace it with another DB?
Are there any other licensing issues for cyrus? I know about
the requirement for keeping and documenting the copyright notices.
Thanks for any help you can provide.
