Definition: Encina

A Unix-based TP monitor from Transarc Corporation, Pittsburgh, PA that is layered over OSF's Distributed Computing Environment (DCE). IBM acquired Transarc in 1994 and based its CICS/6000 TP monitor on Encina. Later renamed the IBM Pittsburgh Lab, the company was the first to successfully process one billion transactions in 24 hours, a breakthrough in computing performance. Encina and BEA Tuxedo are the major TP monitors in the Unix client/server environment.
