Method and apparatus for error detection using a queued direct Input-Output device

In a network computing system having a main storage capable of connecting to at least one application server and an interface element with at least one adapter capable of establishing processing communication with at least one application user(s), a method of error detection comprising the steps of:

• transferring data across said interface element to and from said main storage;
• establishing a queuing mechanism in said main storage;
• providing a plurality of queuing components having attributes of devices to and from which data is to be transferred or received as well as information about the queuing mechanism itself;
• as part of said queuing component, providing a Storage-List-State Block (SLSB) having state indicators that provide state information about a plurality of buffers that make up each queue;
• defining and establishing a plurality of Error States for by said SLSB Status Block;
• setting said Error States in said SLSB each time said interface element detects errors in data stream;
• monitoring the number of said errors for a specified time period;
• determining based on said number of errors detected during said specified time period as whether a session is to be terminated or kept active.
