At the same time as Sun Microsystems Inc previewed its Solaris 2.0 (CI No 1,933), Pittsburgh, Pennsylvania-based Transarc Corp has confirmed that it is adopting Solaris as a reference system for its Encina on-line transaction processing monitor. As Encina is based on the Open Software Foundation’s Distributed Computing Environment, Transarc will also supply an implementation of DCE for Solaris: both will be integrated using SunSoft’s Federated Services. Transarc will ship early versions of Encina and DCE on Solaris 1.0 (which isn’t Unix System V.4-compatible) this year, and will start deliveries for Solaris 2.0 early in 1993. Transarc is also doing a version of release 3 of its Andrew File System, AFS, for Solaris 2.0, which will ship when the operating system arrives. The next version of the Andrew File System will be incorporated wholesale into DCE – its distributed service component is already a central feature of the Open Software Foundation technology.
