This files lists PolyORB's main features, as well as some known
|
|
limitations. These limitations will be addressed in next releases.

|
|
|
Configuration options
|
|
---------------------
|
|
|
|
Different configuration options allow for a complete control of the
|
|
middleware.
|
|
|
|
- PolyORB allows for the dynamic configuration of some of its internals
|
|
through a detailed configuration file (see polyorb.conf for more details).
|
|
|
|
- 3 tasking runtimes:
|
|
- No tasking;
|
|
- Full tasking, using constructions as proposed by the Ada 95
|
|
Reference Manual;
|
|
- Ravenscar, using the Ada Ravenscar profile, ensuring
|
|
determinism.
|
|
|
|
- ORB's request dispatching policies to control thread allocation:
|
|
- Thread Pool;
|
|
- Thread Per Session (i.e. active connection);
|
|
- Thread Per Request;
|
|
- Single Thread (if 'No Tasking' tasking runtime is used).
|
|

|
-- CORBA --
|
|
-----------
|
|
|
|
PolyORB implements a CORBA application personality that supports:
|
|
|
|
- Static invocation models based on generated stub and skeletons,
|
|
- Dynamic Invocation Interface (DII),
|
|
- Dynamic Skeleton Interface (DSI),
|
|
|
|
It also provides an implementation of the CORBA Portable Object
|
|
Adapter (POA).
|
|
|
|
CORBA Services
|
|
--------------
|
|
|
|
PolyORB implements the following CORBA COS Services:
|
|
- Event,
|
|
- Interface Repository,
|
|
- Naming,
|
|
- Time.
|
|
|
|
Note that the current COS Naming implementation does not support
|
|
corbaloc references.
|
|
|
|
IDL Compiler
|
|
------------
|
|
|
|
PolyORB provides idlac, a CORBA 'IDL to Ada compiler' written entirely
|
|
in Ada 95. It generates full stub and skeleton from an IDL contract.
|
|
|
|
It supports all common IDL constructs; yet it does not support the
|
|
following advanced constructs: value-type, abstract interfaces.
|
|
|
|
----------
|
|
-- GIOP --
|
|
----------
|
|
|
|
PolyORB proposes an implementation of the IIOP 1.0, 1.1 and 1.2
|
|
protocols.
|
|
|
|
Request marshaling operations are complete. Some requests messages
|
|
are not implemented, including: Cancel, Locate messages, and request
|
|
fragmentation.
|
|
|
|
IIOP-level interoperability with other ORBs have been tested with
|
|
- Jonathan 3.0
|
|
- omniORB 4.0
|
|
- OpenORB 1.3.0
