Abstract: In one embodiment, a method includes receiving an unstructured data record and parsing the unstructured data record to determine a characterization of the unstructured data record. The characterization includes determination of: a number of fields, a length for the fields, and an order of the fields as stored in the unstructured data record. The method also includes obtaining a first key pair that includes a primary key-name associated with a first key-value and hashing at least the first key-value to obtain a hash value. In addition, the method includes updating the unstructured data record to include the hash value as an indexing key thereby creating a modified data record. Also, the method includes storing the modified data record in a structured database. Moreover, the method includes updating an index of the structured database to include an entry for the modified data record, the entry including the hash value.

Abstract: A method and apparatus for reducing space allocation failures in a computer system that utilizes direct access storage devices to store data. The method comprises the steps of determining if authorization has been given to attempt to allocate an initial space request over more than one volume, and, if so, attempting to allocate space on a plurality of volumes. If the initial space request cannot be allocated on a plurality of volumes, the initial space request is reduced by a preset percentage, the five-extent limit is removed and an attempt is made to allocate the reduced space request on the plurality of volumes with the five extent limit removed. Alternatively, if authorization has not been given to attempt to allocate the initial space request over more than one volume, the initial space request is reduced by a preset percentage, the five-extent limit is removed and an attempt is made to allocate the reduced space request on a single volume.
