DCE Developer's Kit for Sun Platforms
-------------------------------------
For software developers, the OSF DCE offers a complete development
environment for building applications that operate across a
distributed network. DCE services are specifically designed for
distributed environments--making the development of distributed
applications as easy as developing single-system programs. Also,
software developed with DCE is extremely portable and operates across
heterogeneous systems.
Transarc's DCE Developer's Kit for Sun platforms is an early-access
binary release for Sun SPARCstations running SunOS 4.1.x. Because of
the interoperability inherent in the DCE, applications developed on
one platform will run on all other certified implementations of OSF
DCE.
The DCE Developer's Kit includes the "core" DCE components necessary
for DCE application development. All are based on DCE 1.0.1 from the
OSF:
Remote Procedure Call (RPC): The DCE RPC is a distributed
communications mechanism for developing applications that readily
access many different computing resources--even within heterogeneous
environments.
Threads: DCE supports multi-threaded applications, i.e., applications
that use `lightweight' processes to perform many actions
simultaneously. Transarc's DCE Developer's Kit includes
Transarc-developed technology that supports most of the POSIX
threading interface, while preserving the ability for DCE applications
to call many non-threaded UNIX services.
Cell Directory Service (CDS): CDS is the mechanism for naming objects
within a DCE cell (a group of server and client machines). Programs
identify resources by name, without needing to know where the
resources are located.
Security: The DCE Developer's Kit provides the DCE components for
writing applications that support secure communications between
clients and servers.
Time: The Distributed Time Service (DTS) provides a way to synchronize
the clocks on the different machines in a distributed system.
Encina Family of Products for Open OLTP
---------------------------------------
The Encina products from Transarc Corporation are designed to enable
distributed, standards-based online transaction processing (OLTP) in
open computing environments. This product family provides a modular,
multi-layered solution for commercial-grade OLTP in computing
enterprises that span multiple locations, utilize computers from many
vendors, and require access to data that's stored in a variety of
databases.
Currently, Transarc's Encina products have been endorsed by system
vendors including IBM Corporation, Hewlett-Packard Company, Stratus
Computer, NEC and Hitachi. They interoperate via the X/Open XA
interface with relational database management systems including
ORACLE, Informix, Ingres and Sybase.
Based on the Distributed Computing Environment (DCE) from the Open
Software Foundation (OSF), Transarc's Encina products include the
following:
Encina Toolkit: Comprised of the Encina Executive and Server Core,
this product provides standards-based, distributed transaction
processing services that simplify the development of secure,
distributed OLTP applications and support the storage and maintenance
of recoverable data.
Encina Monitor: Building upon the services of the Encina Toolkit and
DCE, the Encina Monitor provides a development environment that
supports the programming or integration of distributed OLTP
applications; a secure execution environment that ensures high
performance and transactional integrity; and an effective
administrative environment that enables the configuration and
management of a distributed system as a cohesiveunit.
Encina Structured File Server (SFS): A record-oriented file system,
Encina SFS provides transactional integrity, high performance,
log-based recovery for fast restarts and broad scalability to support
large databases.
Encina Peer-to-Peer Communiction (PPC) Services: Comprised of the PPC
Executive and PPC Gateway/SNA products, these services support
transactional CPI-C peer-to-peer communication over both the TCP/IP
and SNA (LU6.2) transports. Unique to Transarc, Encina PPC Services
can deliver full sync-level 2 services (two-phase commit).
Encina Recoverable Queueing Service (RQS): Encina RQS provides for the
transactional enqueueing and dequeueing of data--allowing
transactional tasks to be queued for processing while ensuring that
system failures do not result in lost information.
