Minos

Minimalist Notification Service

Minos is a lightweight, portable implementation of the OMG CORBA Notification Service, written in C++. It is not a full implementation of the service specification, but implements an essential subset of its interfaces and a few useful QoS properties.

Minos' major design goals were simplicity and portability. It focuses on a fast and reliable event delivery, whereas sophisticated event filtering was considered to be unimportant.

Here's a short and certainly incomplete list of things that are supported and those that are missing (and may never be implemented):

• Minos implements push and pull style proxy suppliers
• It implements only push style proxy consumers
• It does not implement any of the filter interfaces
• ConsumerAdmin does not support NotifySubscribe, i.e. subscription changes can only be made on proxy suppliers
• SupplierAdmin does not support NotifyPublish, i.e. offer changes can only be made on proxy consumers
• Minos supports the following QoS properties on a per-proxy basis:
• CosNotification::MaxEventsPerConsumer
• CosNotification::MaximumBatchSize
• CosNotification::PacingInterval
• It also supports these QoS properties on a per-event basis:
• CosNotification::StopTime
• CosNotification::Timeout
• Minos supports corbaloc for its EventChannelFactory object ("corbaloc:iiop:<host>:<port>/NotificationService")
• The service can be built on 32-bit Windows or Linux with the following ORBs:
• omniORB 4.1.2
• TAO 1.6
• MICO 2.3.12
• ORBacus 4.3.2
• maybe others...

Please see README.win32 or README.unix in the top-level directory to get instructions for building and running Minos.
