Unisys OS 2200 distributed processing
open-in-new
<p><a href="/facts/Unisys_OS_2200_operating_system/ChN2yNmR">OS 2200</a> supports all commonly used, and many not so commonly used, <a href="/facts/Distributed_computing/o5nyhqTF">distributed processing</a> protocols, APIs, and development technology. </p> <p>The X/Open Distributed Transaction Processing model and standards are the basis for much of the OS 2200 capability. Full support for the <a href="/facts/X/Open_XA/Ug4z2Nmg">X/Open XA</a> APIs including two-phase commit are built into transaction middleware, the database managers, and even clustering. </p><p>The J2EE model is also fully supported. It uses the XA capabilities of the system but provides the J2EE APIs and protocols. </p><p><a href="/facts/IBM_WebSphere_MQ/LyfQzHIX">IBM WebSphere MQ</a> (AKA MQSeries), <a href="/facts/Microsoft_Message_Queuing/EhRQKdb9">MSMQ</a>, and others are all fully integrated into the system taking advantage of the XA and integrated recovery facilities. </p>
