Abstract: Provided are a computer program product, system, and method for determining when to release a lock from a first task holding the lock to grant to a second task waiting for the lock. A determination is made as to whether a holding of a lock to the resource by a first task satisfies a condition and whether the lock is swappable. The lock is released from the first task and granted to a second task waiting in a queue for the lock in response to determining that the holding of the lock satisfies the condition and that the lock is swappable. The first task is indicated in the queue waiting for the lock in response to granting the lock to the second task.

Abstract: A method for allocating a resource to multiple requesters is disclosed. In one embodiment, such a method includes maintaining, for a resource, a regular queue and an express queue. The method receives requests to control the resource and determines, for each request, an anticipated amount of time that the request needs to control the resource. In the event the anticipated amount of time for a request is greater than a selected threshold, the method allocates the request to the regular queue. In the event the anticipated amount of time for a request is less than the selected threshold, the method allocates the request to the express queue. The method provides priority to requests allocated to the express queue over requests allocated to the regular queue. A corresponding system and computer program product are also disclosed.

Abstract: A method, system, and computer program product for managing data sets of a storage facility is disclosed. The method, system, and computer program product include determining, by analyzing a first data set, that the first data set includes a first record having padded data. To identify the padded data, the method, system, and computer program product include comparing at least a portion of the first record of the first data set with a second record of a second data set. Next, the method, system, and computer program product include removing, from the first record of the first data set, the padded data.

Abstract: A plurality of catalogs are maintained, and wherein each catalog of the plurality of catalogs includes data sets and attributes of the data sets. An indication that a new data set is to be defined is received. A selected catalog is determined from the plurality of catalogs, wherein the selected catalog is suitable for including the new data set and attributes of the new data set. An entry that indicates a data set name corresponding to the new data set and an index to the selected catalog is inserted in a group table.

Abstract: Provided are a computer program product, system, and method for recovering a volume table and data sets from a volume. Content from a backup volume table comprising a valid backup of a volume table from backup of the volume is processed to generate a recovery volume table for a recovery volume. The data sets in the volume are processed to determine whether they are valid. The valid data sets are moved to the recovery volume. A data recovery operation is initiated for the data sets determined not to be valid.
