Patent Number Title Of Patent Date Issued
8209294 Dynamic creation of database partitions June 26, 2012
A method and apparatus for managing data in a partitioned data storage space is provided. Data referencing a new data item to be stored in the data storage space is received. It is determined that the data item does not pertain to any previously created partition. In response to the
8195702 Online index builds and rebuilds without blocking locks June 5, 2012
Techniques are provided for processing a CREATE INDEX statement that avoids one or more locks on the underlying table. The processing of such a statement may be divided into a build phase and a cooperation phase. During the build phase, a journal table is created and published. A sna
8135688 Partition/table allocation on demand March 13, 2012
A method and apparatus for the on-demand allocation of segments and creation of metadata for previously-created data storage spaces and partitions are provided. A space is created in a database. As part of this creation process, no segment is allocated for the space. Rather, metadata
8041691 Acquiring locks in wait mode in a deadlock free manner October 18, 2011
Techniques for a data definition language (DDL) statement acquiring a lock on a table in wait mode in a deadlock free manner are provided. A DDL statement specifies metadata of a table that is to be modified, whereas a data manipulation language (DML) statement specifies a table to b
7966330 Techniques for partition pruning June 21, 2011
Techniques are described for performing partition pruning in situations where previous database servers could not. Specifically, techniques are provided for (1) performing partition pruning based on predicates that involve non-prefix subsets of composite partitioning keys, (2) performing
7870174 Reference partitioned tables January 11, 2011
Systems, methodologies, media, and other embodiments associated with supporting reference partitioned tables in a relational database are described. One example method includes identifying a partitioning strategy (e.g., range, list, hash) associated with a parent table that is relate
7814104 Techniques for partition pruning October 12, 2010
Techniques are described for performing partition pruning in situations where previous database servers could not. Specifically, techniques are provided for (1) performing partition pruning based on predicates that involve non-prefix subsets of composite partitioning keys, (2) performing
7774379 Methods for partitioning an object August 10, 2010
The concept of portioning is expanded with a variety of techniques. In particular, one technique involves partitioning an object at multiple levels, where at least one of the levels uses list-based partitioning. Further, a partitioning technique is provided which involves storing a d
7765246 Methods for partitioning an object July 27, 2010
The concept of portioning is expanded with a variety of techniques. In particular, one technique involves partitioning an object at multiple levels, where at least one of the levels uses list-based partitioning. Further, a partitioning technique is provided which involves storing a d
7644106 Avoiding lock contention by using a wait for completion mechanism January 5, 2010
Techniques for avoiding lock contention when processing data definition language (DDL) statements are provided. Some DDL statements modify metadata of a table and then require access to the table. After such a DDL statement modifies the metadata of a table and the updated metadata is
7299239 Methods for partitioning an object November 20, 2007
The concept of partitioning is expanded with a variety of techniques. In particular, one technique involves partitioning an object at multiple levels, where at least one of the levels uses list-based partitioning. Further, a partitioning technique is provided which involves storing a
