In one embodiment, a computer program product for injecting error code includes a computer readable storage medium having computer readable program code embodied therewith. The computer readable program code includes computer readable program code configured to determine critical points in executing code of software under test, computer readable program code configured to determine an appropriate response action for each critical point based on an error encountered at each critical point, computer readable program code configured to inject a critical point segment into the executing code at a corresponding critical point, and computer readable program code configured to output a unique identifier of each critical point segment. In another embodiment, a system includes a processor, and a computer readable storage medium having computer readable program code embodied therewith having the above described functionality. Other systems and computer program products are described according to more embodiments.

A computing system includes a plurality of coupled computing systems, a centralized server and a data set. The system also includes a data sharing controller which includes a primary lock structure that is coupled to the data set when an address space for the data set is allocated and a plurality of secondary lock tables. Each secondary lock table is assigned to a different portion of the data set.

In one embodiment, a system includes logic adapted for receiving a first request to change a state of a first group of catalogs, determining which of a plurality of catalogs belong in the first group, adding a change request for each of the first group of catalogs to a queue for processing, causing processing of each change request in the queue to change the state of each of the first group of catalogs according to the first request, creating a first group result indicating successful or failed state change upon a catalog in the first group of catalogs finishing processing, passing the first group result to an adjacent catalog in the first group of catalogs, removing each catalog that has finished processing from the first group of catalogs, and outputting the group result when there are no adjacent catalogs available to pass the group result.
