CORBA (Cont.)
ActiveX does not require HTML. ActiveX can perform many of the tasks that are also performed with Macromedia's Shockwave, but the ActiveX can create interactivity with much smaller file sizes and bandwidth requirements. As an illustration, visit Macromedia's FutureWave web site at http://www.macromedia.com/futurewave/. See also Distributed Network Computing. See also ActiveX and Visual Basic . Welcome to OTM What exactly are Object Transaction Monitors (OTMs)? In short, OTMs are a new category of middleware that should incorporate much of today's "best-of-breed" middleware technology features. Products in this category should support the object model without compromising the scalability, stability and performance characteristics offered by transaction processing (TP) monitors. OTMs should also combine support for the synchronous communication model (found in most of the middleware categories, such as CORBA and COM) with support for the asynchronous communication model [found in message-oriented middleware products such as Microsoft Message Queue Server (MSMQ) and IBM's MQSeries]. There are a number of OTMs on the market today, although the exact number offered is not clear -- it depends on who is doing the talking and whether a product is generally available or in beta release. The veteran in the OTM market is Microsoft Transaction Server (MTS) from Microsoft Corp., Redmond, Wash., which began shipping in late 1996. M3 (formerly known as "Iceberg"), from Sunnyvale, Calif.-based BEA Systems Inc., was launched this June, with general availability of its first release scheduled for late July. The status of IBM's OTM offering, Component Broker, is unclear. Depending on whom you talk to at IBM, the next version of Component Broker is either in the early beta or late beta phase. http://www.adtmag.com/pub/Aug98/fe801-2.htm Welcome to MTS Microsoft Transaction Server is a distributed runtime environment for COM objects that began shipping approximately 18 months ago. It provides a sophisticated infrastructure for activating and running objects across the network. MTS provides automatic transaction management, database connection pooling, process isolation, automatic thread-pooling, automatic object instance management, resource sharing, role-based security, transaction monitoring within distributed applications and much more. These services are necessary for scaling server-side components and supporting a substantial number of concurrent client requests. MTS performs all of these services automatically, and without the need for application developers to write special code. A developer can therefore develop server-side components with a single client in mind. http://www.adtmag.com/pub/Aug98/fe801.htm | ||||
