1.Introduction to basic SQL*Plus and SQL commands in oracle 9i
 
20:41
A relational database management system (RDBMS) is a database management system (DBMS) that is based on the relational model as invented by E. F. Codd, of IBM's San Jose Research Laboratory. Many popular databases currently in use are based on the relational database model.RDBMSs have become a predominant choice for the storage of information in new databases used for financial records, manufacturing and logistical information, personnel data, and much more since the 1980s. Relational databases have often replaced legacy hierarchical databases and network databases because they are easier to understand and use. However, relational databases have been challenged by object databases, which were introduced in an attempt to address the object-relational impedance mismatch in relational database, and XML databases. Object-relational database management system (ORDBMS) ============================================ An object-relational database can be said to provide a middle ground between relational databases and object-oriented databases (OODBMS). In object-relational databases, the approach is essentially that of relational databases: the data resides in the database and is manipulated collectively with queries in a query language; at the other extreme are OODBMSes in which the database is essentially a persistent object store for software written in an object-oriented programming language, with a programming API for storing and retrieving objects, and little or no specific support for querying. Object-relational database management systems grew out of research that occurred in the early 1990s. That research extended existing relational database concepts by adding object concepts. The researchers aimed to retain a declarative query-language based on predicate calculus as a central component of the architecture. Probably the most notable research project, Postgres (UC Berkeley), spawned two products tracing their lineage to that research: Illustra and PostgreSQL. Many of the ideas of early object-relational database efforts have largely become incorporated into SQL:1999 via structured types. In fact, any product that adheres to the object-oriented aspects of SQL:1999 could be described as an object-relational database management product. For example, IBM's DB2, Oracle database, and Microsoft SQL Server, make claims to support this technology and do so with varying degrees of success. SQL(Structures Query Language) ======================== SQL was initially developed at IBM by Donald D. Chamberlin and Raymond F. Boyce in the early 1970s. This version, initially called SEQUEL (Structured English Query Language), was designed to manipulate and retrieve data stored in IBM's original quasi-relational database management system, System R, which a group at IBM San Jose Research Laboratory had developed during the 1970s.The acronym SEQUEL was later changed to SQL because "SEQUEL" was a trademark of the UK-based Hawker Siddeley aircraft company. SQL*Plus ======= SQL*Plus is a command line SQL and PL/SQL language interface and reporting tool that ships with the Oracle Database Client and Server software. It can be used interactively or driven from scripts. SQL*Plus is frequently used by DBAs and Developers to interact with the Oracle database. If you are familiar with other databases, sqlplus is equivalent to: "sql" in Ingres, "isql" in Sybase and SQL Server, "sqlcmd" in Microsoft SQL Server, "db2" in IBM DB2, "psql" in PostgreSQL, and "mysql" in MySQL.

Explaining the Explain Plan: Interpreting Execution Plans for SQL Statements
 
01:04:02
Presenter: Maria Colgan, Oracle Corporation The execution plan for a SQL statement can often seem complicated and hard to understand. Determining if the execution plan you are looking at is the best plan you could get or attempting to improve a poorly performing execution plan can be a daunting task, even for the most experienced DBA or developer. This session examines the different aspects of an execution plan, from selectivity to parallel execution, and explains what information you should be gleaming from the plan and how it affects the execution. It offers insight into what caused the Optimizer to make the decision it did as well as a set of corrective measures that can be used to improve each aspect of the plan.

Tracing: Transaction ST12 = Combination of two transactions . SAT (ABAP Trace) , ST05 = SQL Trace SQL Trace: To monitor the database access of reports and transactions. Less common traces : Enqueue Trace: (the locking system),RFC Trace, Table buffer trace: Performance Improvements ABAP Coding: Keep an eye on those loops. Select statements in loops = absolutely avoid = use for all entries instead Function call, or performs in loops = re - visit and see if you can optimize The "READ TABLE" statement Sorted table- Binary search .. Or even better use "Index" on internal tables. Use mass operations on internal table = internal table copy one to another, Append lines of int_fligh1 to int_fligh2. Use field symbols to modify internal table in a loop (minor improvement ) A little trick if you call performs in a loop:: Use static variables Avoid sleep, wait etc commands.. Or synchronous RFC calls 2)Database bottleneck Use Indexes : Make sure Indexes are being used in your select statement (check with trace if needed) Extreme case , create new index (this has the disadvantage of making the insert slower) Select -- End select loop : Usually database optimiser will fix it, still avoid it Select * into corresponding fields = about a millisecond slower Make clever use of inner joins Use views Use (max,min, avg): example : Select max( flightnum ) from flight . GET RUN TIME command Reduce I/O first, then memory, then CPU activity.Field-groups can be useful for multi-level sorting and displaying. However, they write their data to the system's paging space, rather than to memory (internal tables use memory)

Oracle X$TRACE, Wait Event Internals and Background Process Communication
 
01:48:41
In this session we will look into some internals of Oracle background process communication and also some special types of wait events that most people aren’t aware of. We will use some exotic tracing for internals research and fun and some of this stuff is actually useful in real life too! I’m not going to reveal everything upfront, as this is a secret internals hacking session after all ;-) We will use various techniques to research what the “reliable message” wait event is about and how reliable background process communication is orchestrated in Oracle. This is a hacking session, not formal structured training, so I’ll just do free form demos and talk (probably no slides, just hacking stuff on the command line).

Top Nine Coding Guidelines for Oracle PL/SQL
 
08:00
My take, as of November 2015, of some of the most helpful guidelines to follow when writing PL/SQL code: 1. MAXSQL - maximize use of SQL first and foremost 2. SPOD - single point of definition 3. TRACE - production-available application-level tracing 4. LOG - consistent, encapsulated error logging 5. BULK - avoid row by row 6. OBVIOUS - make your code tell its own story, comment when it can't 7. NESTPROG - use nested subprograms 8. DECLARE - use declarative features of language 9. WARN - use compile-time warnings Accompanying blog post: http://stevenfeuersteinonplsql.blogspot.com/2015/10/your-ideas-for-more-important-plsql.html ======================================== Practically Perfect PL/SQL with Steven Feuerstein Copyright © 2015 Oracle and/or its affiliates.
