摘要： Described are embodiments of an invention for allocating storage space in a storage system for critical data sets. The computing environment includes at least one server including a processor and memory. The server is coupled to storage. The memory further includes a storage manager including an allocation module and an alert module. The storage manager defines a common area for storing non-critical data sets and critical data sets in the storage group. The storage manager also defines a critical reserve area for storing only critical data sets in the first storage group. A predefined percentage of available storage space is reserved for the critical reserve area. The predefined percentage of available space is determined by comparing the available storage space within the critical reserve area to the storage space in the storage group. Upon allocating additional storage to the storage group, the allocation module allocates an amount of the additional storage space to the critical reserve area such that the predefined percentage of available storage space is maintained in the critical reserve area.

摘要： A central hub is coupled to a plurality of computational devices. The central hub stores a data structure that grants locks for accessing common data stored at the central hub, wherein the common data is shared by the plurality of computational devices. Each computational device maintains locally those locks that are held by the computational device in the data structure stored at the central hub. In response to a failure of the data structure stored at the central hub, a selected computational device of the plurality of computational devices is determined to be a manager system. Other computational devices besides the manager system communicate to the manager system all locks held by the other computational devices in the data structure stored at the central hub. The data structure and the common data are generated and stored at the manager system. Transactions are performed with respect to the data structure stored at the manager system, until the data structure stored at the central hub is operational.

摘要： A method is disclosed to detect and repair a broken dataset. The method creates and maintains a backup log and an update log for a dataset. If the method finds a dataset structural error, then the method deletes the corrupted dataset, obtains the most current backup copy of the dataset, obtains all dataset updates made after the most current backup copy of the dataset was saved, and generates a recovered dataset using the most current backup and the dataset updates.

摘要： A data structure maintained in a computational device stores how many control areas splits have occurred to store a data set, wherein each control area split causes an addition of a single new control area. A command is received to add a new data record to the data set. A determination is made as to whether adding the new data record to the data set will result in a threshold for control area splits to be exceeded. In response to determining that adding the new data record to the data set will result in the threshold for control area splits to be exceeded, creating at least two new control areas in addition to continuing to use one existing control area for storing the data set.

摘要： Provided are a method, system, and program for allocating data sets to a container data set. A container data set is allocated in a storage system. An entry is included in a file allocation catalog for the allocated container data set indicating an address range of data allocated to the container data set, wherein the file allocation catalog maps data sets to address ranges in the storage system. A virtual file allocation catalog for the container data set is generated. A request is received to allocate a data set. A determination is made as to whether the data set to allocate has a size less than a threshold size. An entry is included in the virtual file allocation catalog to allocate the data set in the address range of the container data set in response to determining that the data set to allocate size is less than the threshold size.

摘要： An apparatus, system, and method are disclosed for modifying data set names. A communication module receives a data set name as an index of a catalog entry for a catalog. The data set name comprises at least two qualifiers. A modification module modifies at least one data set name qualifier using a naming algorithm, wherein an alias qualifier is not modified. A store module stores the catalog entry indexed with the modified data set name in order to optimize the location of that entry within the catalog.
