| 20080243865 | Maintaining global state of distributed transaction managed by an external transaction manager for clustered database systems - In accordance with an embodiment of the present invention, a transaction tracking mechanism is provided by a database server cluster to keep track of a global state of a distributed transaction. The global state of the distributed transaction comprises one or more statuses that are associated with one or more transaction branches that are part of the distributed transaction. The global state may be associated with a global lock. Through using the global state in association with the global lock, problems such as partial commits, data inconsistency, access contentions and deadlocks may be avoided when the database server cluster processes the distributed transaction. | 10-02-2008 |
| 20110047330 | DATABASE OPERATION-AWARE STRIPING TECHNIQUE - A method, device, and computer readable medium for striping rows of data across logical units of storage with an affinity for columns is provided. Alternately, a method, device, and computer readable medium for striping columns of data across logical units of storage with an affinity for rows is provided. When data of a logical slice is requested, a mapping may provide information for determining which logical unit is likely to store the logical slice. In one embodiment, data is retrieved from logical units that are predicted to store the logical slice. In another embodiment, data is retrieved from several logical units, and the data not mapped to the logical unit is removed from the retrieved data. | 02-24-2011 |

| 20110238655 | SYSTEM AND METHOD FOR PROVIDING HIGHLY AVAILABLE DATABASE PERFORMANCE - A system and method for enabling a second database instance to more quickly process a request to execute a database statement that has previously been executed by a first database instance is described. In one embodiment, the method involves sending the database statement from the first database instance to the second database instance, and generating by the second database instance one or more structures needed to prepare the statement for execution, such as a parse tree and an execution plan for the statement. If at some point in the future, the second database instance receives a request to execute the same statement, the above structures can be used for execution, thereby eliminating the need for one or more potentially time-consuming operations, such as generation of a parse tree or execution plan for the statement. | 09-29-2011 |

| 20090155435 | Flip Tray - A flip tray is provided that includes a transparent, compartmentalized container body and a flexible sealing sheet sealed to partition walls and to the peripheral rim of the compartmentalized container body. Plant material with active respiratory activity such as fruits and vegetables are disposed in the compartments of the transparent container body. Each of the compartments exchanges respiratory gases through the micro-perforated sealing sheet individually in a controlled manner. A tray having a completely flat bottom is secured to the container body so as to underlie the flexible sealing sheet and includes peripheral vent conformations. | 06-18-2009 |
