Dublin-based object house Iona Technologies Ltd is setting out its CORBA 2.0 stall, saying it will deliver C++ mapping and interoperability protocol for its Orbix object request broker in the third quarter, Ada mapping by the end of the year, and an interface repository and Smalltalk mapping in the first quarter of next year. Iona is beta testing Orbix for OS/2 and says it will be up on Mac OS 7.5 next quarter. Iona also announced general shipments of a multithreaded Orbix for SunSoft Inc’s Solaris. Orbix-MT costs $6,500 and upgrades to it cost $1,500. Orbix-MT implementations are under way for the HP-UX, AIX, Digital Unix and Windows NT operating systems.
