05 How to configure Sub partition using rang & list in oracle
 
16:31
You can create subpartitions in a composite partitioned table using a subpartition template. A subpartition template simplifies the specification of subpartitions by not requiring that a subpartition descriptor be specified for every partition in the table. Instead, you describe subpartitions only once in a template, then apply that subpartition template to every partition in the table. For interval-* composite partitioned tables, the subpartition template is the only way to define subpartitions for interval partitions. The subpartition template is used whenever a subpartition descriptor is not specified for a partition. If a subpartition descriptor is specified, then it is used instead of the subpartition template for that partition. If no subpartition template is specified, and no subpartition descriptor is supplied for a partition, then a single default subpartition is created. Specifying a Subpartition Template for a *-Hash Partitioned Table In the case of [range | interval | list]-hash partitioned tables, the subpartition template can describe the subpartitions in detail, or it can specify just the number of hash subpartitions. The following example creates a range-hash partitioned table using a subpartition template: CREATE TABLE emp_sub_template (deptno NUMBER, empname VARCHAR(32), grade NUMBER) PARTITION BY RANGE(deptno) SUBPARTITION BY HASH(empname) SUBPARTITION TEMPLATE (SUBPARTITION a TABLESPACE ts1, SUBPARTITION b TABLESPACE ts2, SUBPARTITION c TABLESPACE ts3, SUBPARTITION d TABLESPACE ts4 ) (PARTITION p1 VALUES LESS THAN (1000), PARTITION p2 VALUES LESS THAN (2000), PARTITION p3 VALUES LESS THAN (MAXVALUE) ); This example produces the following table description: Every partition has four subpartitions as described in the subpartition template. Each subpartition has a tablespace specified. It is required that if a tablespace is specified for one subpartition in a subpartition template, then one must be specified for all. The names of the subpartitions, unless you use interval-* subpartitioning, are generated by concatenating the partition name with the subpartition name in the form:

Thinking in Parallel
 
01:02:25
The Java 8 Streams library makes it easy to run code in parallel. A common error is code that works when run sequentially but that misbehaves when run in parallel. This is often caused by programmers who are stuck in a mode of imperative, left-to-right thinking. This leads to an iterative style in which data is mutated and where the next result depends on the result of the previous computation, creating barriers to parallel computation. This presentation covers an alternative programming technique called array programming, where operations are applied on data aggregates instead of individual elements. It also includes examples and demonstrations that illustrate these techniques and how they lead to easier-to-understand, parallel-ready code.

Turning Relational Database Tables into Spark Datasources
 
55:43
https://developer.oracle.com/code/online | Kuassi Mensah: This session presents a Spark data source for joining big data with master data in an RDBMS. It describes how such an implementation: Allows parallel and direct access to the RDBMS database (with the option of controlling the number of concurrent connections). Introspects the RDBMS table, generates partitions of Spark JDBCRDDs based on the split pattern, and rewrites Spark SQL queries into the RDBMS SQL dialect. Uses hooks in the JDBC driver for faster type conversions. Pushes down predicates to the RDBMS, prunes partitions based on the where clause, and projects columns to the RDBMS to reduce the amount of data returned and processed on Spark. Writes back the result set to the RDBMS table for use by traditional BI tools

Demonstrating Oracle DB Elapsed Time and Wall Time With Parallel Query
 
03:37
Is it really true? In my recent postings I wrote that when using parallel query a SQL statement's wall time is roughly equal to its elapsed time divided by the number of parallel query slaves. To check I ran an experiment and posted the results. The results are both obvious and illuminating. If you don't want to read but just sit on the couch and watch a video, you're in luck! I created a special video clip demonstrating what I wrote about. The main video clip is from my OraPub Online Institute video seminar, Tuning Oracle Using An AWR Report - Part 1. (NOT Part 2 as the video shows) From my blog posting: http://blog.orapub.com/20140907/watch-oracle-database-elapsed-time-and-wall-time-with-parallel-query.html For more information on OraPub r for more great education, go to www.orapub.com
