“External tables can be a fantastic tool for reading files into your database using SQL,” says Oracle SQL Developer advocate Chris Saxon. “However, they can be a bit tricky to work with.” In this 2 Minute Tech Tip recorded at ODTUG Kscope 2018, Chris explains how using the external table parameter override clause can make things a lot less tricky, and, even better, how Oracle Database 18c allows you to create inline external tables. https://developer.oracle.com/ https://cloud.oracle.com/en_US/tryit

In this free tutorial you will learn how to generate and read (interpret) an execution plan in Oracle Databases. See more FREE Oracle Tuning tutorials at http://skillbuilders.com/free-oracle-tutorials. Understanding what the Oracle Database does with your SQL is essential to tuning - and the execution plan is the key. Oracle Certified Master DBA John Watson will provide a brief introduction (4 minutes) - which includes John's tuning methodology, then demonstrate EXPLAIN PLAN, SQL*Plus AUTOTRACE and DBMS_XPLAN.DISPLAY_CURSOR. In the tutorial, John will teach you: - How to read an execution plan - Find the 1st step in the plan - Decipher the order of the steps in the plan - That EXPLAIN PLAN can be very misleading Prerequisites: To get the most from this tutorial, you should: 1 Know how to code SQL 2 Be familiar with SQL*Plus 3 Know - in very general terms - what an execution plan is. 4 Have a basic understanding of the Library Cache (this is where Oracle Database stores parsed SQL statements) 5 Have a basic understanding of the Cost Based Optimizer (this is the part of the database that parses your SQL, creates an execution plan. Hopefully the correct - most efficient - plan).

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

One of SQL Developer’s most popular features has undergone a significant upgrade. Users can quickly define and recall delimited or Excel files to be imported to a new or existing Oracle table. Data preview and validation is provided for each column, as well as ‘best guess’ data type and date format mask mapping. This process can now be automated via the SQL Developer command line interface (SDCLI) ‘Import’ command. NOTE: This is a video only. There is no audio. Copyright © 2015 Oracle and/or its affiliates.

Jean-Marc Wattecant, from Airbus Flight & Integration Test Centre Data Processing, attended Oracle OpenWorld 2014 and spoke with us about their use of Oracle's Big Data Appliance. Airbus chose the Appliance for data management on their prototype aircraft. They connected a lot of sensors which are collecting a lot of data which they need to analyze faster and faster in order to meet their test schedule. Airbus believes that the Oracle Big Data Appliance is a significant enabler for them for many projects and will reduce not only the time to test prototypes, but also the time to market as well. They plan to expand their big data project with Oracle's big data mining and discovery tools to go beyond reactive to proactive analytics.

See all 5 tutorials, free, at SkillBuilders.com/OracleTuningFullTableScans. In summary, serial full table scans were always indirect before 11.2, parallel scans always direct before 11.2. These are the two critical parameters. That hidden parameter _serial_direct_read, remember, defaults to auto so your application may start behaving very differently as you upgrade from 11.2.01 or 11.2.02. Parallel_degree_policy, that defaults to manual. But again, it becomes an option when you go to 11.2 to enable the automatic facility which allows not only automatic tuning to the degree of parallelism but also enables the ability to make indirect reads when doing a full table scan.

China Sun Yat-sen University and Dell co-established course IT System Management Introduction Lecture 5 Oracle Database Performance Tuning - Guy Harrison The Oracle database is highly tuneable with many options for optimizing performance. However, the sheer quantity of tuning options can be overwhelming, and you can waste precious time unless you know which tuning activities are most likely to provide a return on your time investment. In this lecture we'll review some of the fundamental Oracle performance tuning practices and see how to use these in a ystematic way to improve Oracle performance. Topics will include workload and SQL optimization, identification and elimination of key contention points, configuring memory to avoid physical IO, and disk IO optimization. We will also see how to use commercial tools to assist in Oracle database tuning. This lecture will be based on materials from the lecturer's book on Oracle performance: http://product.china-pub.com/60833).
