Julian Dontcheff - Migrating to Oracle Cloud using the Oracle Database In-Memory Advisor
 
43:56
The presentation is about best practices for how to test new Oracle options using Oracle database cloud. When a multitenant database running on premise needs to be migrated to the Oracle database cloud one should consider the performance load caused by one or more PDBs inside the container. Especially the impact of upgrading to in-memory (12.1.0.2) on the PDBs. We show how to use the in-memory advisor in order to tune the existing structures for in-memory and how to validate this on the database cloud using RAT & SQL tuning advisor.

Held on June 13 2018 Explore and get the best out of Oracle Database In-Memory Implementations with Markus Kissling, Product Manager for Database In-Memory in EMEA, based in Germany. The session began with an overview about Database In-Memory, the breakthrough with the Dual Format Architecture, allowing you to simply flip a switch to active, populate the tables, partitions, sub-partitions, materialized views into the column store when altering this segments with inmemory subclause and you’re done. We explored how to find the candidates for In-Memory with our advisors. We also went deep on the following topics: 9:00 What are Analytic Queries and how do they have to look to get the most out of things like In-Memory Aggregation? 21:50 The Dual Format Architecture 22:30 Apply the latest Proactive Bundle Patches to get the latest innovations, in addition to fixes. 24:50 Think about proper preparation and unset some Database Parameters (e.g. deactive dynamic sampling). 28:30 A short demo demonstrating how easy it is to use Database In-Memory. 47:20 Key resources on our blog http://blogs.oracle.com/in-memory.

How to Tune Oracle SQL - Lesson 4 - Understanding The Bind Step
 
07:50
Learn how to tune Oracle Database SQL! In this lesson you will learn that before SQL can be executed it must be parsed and part of the parse process is "bind". Learn what bind variables are, how variables impact SQL, why they are so important, when to use them and when not to use them. Writing SQL that performs well means understanding what Oracle is doing to the SQL: how it is executing the code, and why it is executing it that way. Then make changes needed to let Oracle run the code in a more efficient manner.

Table Compression Enhancement in Oracle Database 11g R2
 
05:00
Table Compression: Overview Oracle Database supports three methods of table compression: 1.Basic table compression 2.OLTP table compression Oracle Corporation recommends to compress all data to reduce storage costs. The Oracle database can use table compression to eliminate duplicate values in a data block. For tables with highly redundant data, compression saves disk space and reduces memory use in the database buffer cache. Table compression is transparent to database applications. The table_compression clause is valid only for heap-organized tables. The COMPRESS keyword enables table compression. The NOCOMPRESS keyword disables table compression. NOCOMPRESS is the default. With basic compression, the Oracle database compresses data at the time of performing bulk load using operations such as direct loads or CREATE TABLE AS SELECT. With COMPRESS FOR OLTP, the Oracle database compresses data during all DML operations on the table.
