20100264914 | SYSTEM AND METHOD FOR ESTIMATING FORMATION CHARACTERISTICS IN A WELL - A technique utilizes the acquisition of data via nuclear magnetic resonance at multiple depths of investigation in a well region. The acquired data is processed to estimate variable fluid mixture densities at different radial depths. The variable fluid mixture densities and a radial response from a density tool, for example, can be used to calculate an effective fluid mixture density and used to interpret density logs. Other logs such as neutron log, induction resistivity log, and dielectric permittivity log can be combined with NMR. For these tools a corresponding effective formation property can be calculated and used to determine other formation characteristics, such as total porosity, total density, dielectric permittivity, electric resistivity, and formation characteristics derivable from these. | 10-21-2010 |

20140164331 | TECHNIQUES FOR BACKUP RESTORE AND RECOVERY OF A PLUGGABLE DATABASE - A container database stores redo records and logical timestamps for multiple pluggable databases. When it is detected that a first read-write instance of the pluggable database is opened and no other read-write instances of the pluggable database are open, offline range data associated with the pluggable database is updated. When it is detected that a second read-write instance of the pluggable database is closed, and the second read-write instance is the last open read-write instance, the offline range data associated with the pluggable database is updated. The pluggable database is restored to a logical timestamp associated with a restore request based on the offline range data. | 06-12-2014 |
20140258223 | ADAPTIVE HIGH-PERFORMANCE DATABASE REDO LOG SYNCHRONIZATION - A method, system, and computer program product for adaptive high-performance database redo log synchronization. The method commences upon performing a write operation of a redo log entry, the write operation concluding with an indication of completion of the write operation of the redo log entry. Any number of committing processes may be waiting for the indication of completion, and upon indication of completion, then (using a first synchronization mode) the processes or proxy measures the waiting time as experienced by the committing processes (e.g., while waiting for the indication of completion of the write operation of the redo log entry). In some cases a second synchronization mode would introduce less latency than the first synchronization mode, so the system changes to a second synchronization mode. The system can also change mode when a predicted second mode waiting time is smaller than the measured waiting time. | 09-11-2014 |

20090307160 | PARALLEL GENERATION OF A BAYESIAN NETWORK - A method for generating a Bayesian network in a parallel manner is based on an initial model having a plurality of nodes. Each node corresponds to a variable of a data set and has a local distribution associated therewith. The method includes assigning a plurality of subsets of the nodes to a respective plurality of constructors. The plurality of constructors is operated in a parallel manner to identify edges to add between nodes in the initial model. The identified edges are added to the initial model to generate the Bayesian network. The edges indicate dependency between nodes connected by the edges. | 12-10-2009 |

20140279917 | Techniques To Parallelize CPU and IO Work of Log Writes - Techniques are provided for managing cached data objects in a mixed workload environment. In an embodiment, a system, log data is stored in one or more buffers. In response to receiving a request to perform a logical write, a first process writes a first portion of the log data to a log file in persistent storage. While the first portion of the log data is being written to the log file, a second process writes a second portion of the log data in the one or more buffers to the log file in persistent storage. In another embodiment, a request to perform a second logical write may be received before the first logical write completes. While the first log data is being written to the log file, one or more processes write second log data for the second logical write to the log file. | 09-18-2014 |
