Computer program product for queuing and retrieving data objects to and from a shared storage medium

A program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine to perform method steps for interacting with a shared storage medium comprising a ready queue and a staging queue, the method steps comprising:

• (1) causing a record having a public key stored therein to be retrieved from said ready queue, said record also having stored therein at least a portion of a data object and a private key;
• (2) determining whether any segments of said data object are stored on said staging queue;
• and
• (3) if it is determined that one or more segments of said data object are stored on said staging queue, then causing any records having said private key stored therein to be retrieved from said staging queue in the order in which said any records were stored on said staging queue.

A program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine to perform method steps for managing a shared storage medium comprising a ready queue and a staging queue, the method steps comprising:

• (1) receiving (N-1) first requests to store (N-1) portions of a data object along with a private key in said staging queue;
• (2) storing said (N-1) portions of the data object along with a private key in said staging queue on a per private key first-in first-out basis;
• (3) receiving a second request to store a portion of the data object along with a public key and the private key in said ready queue;
• and
• (4) storing said portion of the data object along with the public key and the private key in said ready queue.

A program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine to perform method steps for managing a shared storage medium comprising a ready queue and a staging queue, the method steps comprising:

• (1) receiving a first request to retrieve a record having a particular public key stored therein from said ready queue;
• (2) retrieving a record having said particular public key from said ready queue, said record also having stored therein at least a portion of a data object and a private key;
• (3) receiving (N-1) second requests to retrieve from said staging queue records having stored therein said private key;
• and
• (4) retrieving (N-1) records from said staging queue, each of said (N-1) records having stored therein one of (N-1) segments of the data object and the private key, said (N-1) records being retrieved from said staging queue in the order in which they were stored in said staging queue.

A computer program product comprising a computer useable medium having computer program logic recorded thereon for enabling a processor in a computer system to interact with a shared storage medium comprising a ready queue and a staging queue, the computer program logic comprising:

• means for enabling the processor to determine whether a data object is larger than available storage capacity of a working storage associated with an application, a public key being associated with the data object, said public key being available to all applications;
• private key generating means, responsive to a determination that the data object is larger than available storage capacity of the working storage, for enabling the processor to generate a private key for the data object;
• dividing means, responsive to operation of said private key generating means, for enabling the processor to divide the data object into N segments;
• staging queue storing means, responsive to operation of said dividing means, for enabling the processor to cause segments 2 through N of the data object to be stored in said staging queue via said working storage, said private key being stored with each of said segments 2 through N in said staging queue;
• and
• ready queue storing means, responsive to operation of said staging queue storing means, for enabling the processor to cause segment 1 of the data object, said public key, and said private key to be stored in said ready queue, wherein said private key becomes available to all applications once stored in said ready queue.

• determining means for enabling the processor to determine whether any segments of said data object are stored on said staging queue;
• and
• means, responsive to a determination that one or more segments of said data object are stored on said staging queue, for enabling the processor to cause any records having said private key stored therein to be retrieved from said staging queue in the order in which said any records were stored on said staging queue.

• means for enabling the processor to receive (N-1) first requests to store (N-1) portions of a data object along with a private key in said staging queue;
• means for enabling the processor to store said (N-1) portions of the data object along with a private key in said staging queue on a per private key first-in first-out basis;
• means for enabling the processor to receive a second request to store a portion of the data object along with a public key and the private key in said ready queue;
• and
• means for enabling the processor to store said portion of the data object along with the public key and the private key in said ready queue.
