Abstract: In determining code coverage, execution data indicative of portions of a program that have been executed for testing is received. The program is analyzed based on the execution data and a control flow for the program. Based on the analysis, it is determined that additional portions of the program, which are not indicated by the execution data, have also been executed. Related methods, systems, and computer program products are also discussed.

Abstract: In certain embodiments, facilitating software acquisition includes accessing a memory storing software programs. A selected software program is identified. One or more product requirements of the selected software program and one or more target parameters of a target environment for the selected software program are determined. One or more commands to install the selected software program at the target environment according to the product requirements and the target parameters are determined.

Abstract: Resource contention monitoring and analysis are provided for a single system or multi-system environment. Resource contention is tracked at a task level when contention occurs by listing each owner of a resource in a blocker list and each waiter for the resource in a waiter list. Each list is ordered oldest to newest so each instance of contention is added to the end of the respective list. The resource request and contention lists are cross-linked to provide easy coordination between the resource queues and the contention lists. Techniques for analyzing contention using the lists, including deadlock analysis, are described.

Abstract: A computer complex is provided with a mechanism for message delivery and redelivery in a controlled manner through the use of distributed shared memory. This provides a mechanism for overall computer system complex operation from a plurality of consoles which are registered or identified to the system and which particularly enhances capabilities for remote operation. In this way the complex can be made to look like a single system. Direct communication between any pair of systems is provided, say, by channel-to-channel adapters. Message information is maintained in each system which can also communicate with shared storage to establish update level information regarding locally maintained message information.
