Abstract: An efficient input/output (I/O) retry method which can be implemented in an enterprise-server configured with QDIO. The method can include attempting a QDIO-based data transfer between outbound and inbound queues in respective sending and target LPARs in the enterprise server. Responsive to detecting a busy condition resulting from the attempt; it can be determined whether the busy condition arose from an asynchronous busy condition. If it is determined that the busy condition arose from an asynchronous busy condition in the target LPAR, any attempt to retry the QDIO-based data transfer can be delayed. Subsequent to the delay, the QDIO-based data transfer can be re-attempted.

Abstract: A microprocessor with built-in test, comprising: a register for retaining a test address of a test program; a next address generation logic for generating a command address of a command scheduled to be executed next, based on a command address of a command to be executed next; a first multiplexer for selecting, based on a test mode signal, any one of a boot address specifying a bootstrap program and the test address; a second multiplexer for selecting, based on a reset signal, any one of the command address of the command scheduled to be executed next and the address selected by the first multiplexer; and a program counter for retaining the address selected by the second multiplexer and for outputting the retained address to the next address generation logic as the command address of the command to be executed next.

Abstract: A network device. The network device includes a least one communication port that allows communication with at least one other network device and storage to store a rules database. At least one health monitor module receives an event notification, then accesses the rules database to locate a matching rule for the event notification and perform any tasks determined by the rules database.

Abstract: Disclosed are a method and system for performing regression tests in a state-dependent data processing environment where data are processed by means of at least one function having a signature of defined parameters and corresponding values. A regression test is performed using at least one pre-determined set of test data and one pre-recorded function test case corresponding to said signatures and being used to execute said at least one pre-recorded function test case. The proposed mechanism particularly comprises the step of adapting said at least one function test case or said at least one set of test data to any changed signatures caused by a state transition of said data processing system. The mechanism thus provides automated regression tests in such a data processing environment and enables re-execution of a regression test in a changed context of the underlying data processing environment.
