Abstract: Embodiments relate to providing a data stream interface for offloading the inflation/deflation processing of data to a stateless compression accelerator. An aspect includes transmitting a request to inflate or deflate a data stream to a compression accelerator. The request may include references to an input buffer for storing input data from the data stream, an output buffer for storing processed input data, and a state data control block for storing a stream state. The stream state is provided to the compression accelerator to continue processing the data stream responsive to the request being a subsequent request. The compression accelerator is instructed to store a current stream state in the state data control block responsive to the request being a non-final request. Accordingly, the current stream state is received from the compression accelerator responsive to the request being a non-final request. The processed input data is received from the compression accelerator.

Abstract: An output sequence of data elements is processed. The output sequence of data elements represents a sequence of input data elements in a compressed format. An output data element comprises a backward reference for each string in the input data elements that occurs again in an input data element that is used to produce the output data element. A backward reference identified in a selected output data element is used for selecting the string to which it refers in the stored input data elements. The selected string is combined with strings of one or more subsequent output data elements. A matching sequence in the stored input data elements matching at least part of one or more combined strings is found. A combined string of the one or more combined strings having the longest matching sequence is selected. The backward reference is redefined to indicate the longest matching sequence.

Abstract: A method, system, and computer program product are described. The method of testing a device driver includes executing a test case for the device driver, the device driver receiving version information specifying a targeted version of a data manipulation device to be targeted by the device driver from the test case or the device driver determining the targeted version of the data manipulation device independently of the test case.

Abstract: A computer-implemented method for monitoring server stability based on a stability time specification of a server includes specifying a stability time for the server, wherein the stability time is defined as a time between a starting state of the server and a stability point of the server. The server activity is monitored by an availability manager to determine an availability status of the server. Responsive to the server activity progressing to the stability point within the stability time, an embodiment determines that the server is stable. Responsive to the server activity failing to progress to the stability point within the stability time, an embodiment determines that the server is unreliable.

Abstract: The stability and availability status of a server is determined by monitoring the stability time specification of the server. The stability time is set for the server and defined as a time between a starting state of the server and a stability point of the server. The server activity is monitored by an availability manager to determine an availability status of the server. Responsive to the server activity progressing to the stability point within the stability time, an embodiment determines that the server is stable. Responsive to the server activity failing to progress to the stability point within the stability time, an embodiment determines that the server is unreliable.
