The document provides an overview of analyzing performance data using the Automatic Workload Repository (AWR) in Oracle databases. It discusses how AWR collects snapshots of data from V$ views over time and stores them in database history views. It highlights some key views used in AWR analysis and factors to consider like snapshot intervals and timestamps. Examples are provided to show how to query AWR views to identify top SQL statements by CPU usage and analyze performance metrics trends over time.
Understanding my database through SQL*Plus using the free tool eDB360Carlos Sierra
This session introduces eDB360 - a free tool that is executed from SQL*Plus and generates a set of reports providing a 360-degree view of an Oracle database; all without installing anything on the database.
If using Oracle Enterprise Manager (OEM) is off-limits for you or your team, and you can only access the database thorough a SQL*Plus connection with no direct access to the database server, then this tool is a perfect fit to provide you with a broad overview of the database configuration, performance, top SQL and much more. You only need a SQL*Plus account with read access to the data dictionary, and common Oracle licenses like the Diagnostics or the Tuning Pack.
Typical uses of this eDB360 tool include: databases health-checks, performance assessments, pre or post upgrade verifications, snapshots of the environment for later use, compare between two similar environments, documenting the state of a database when taking ownership of it, etc.
Once you learn how to use eDB360 and get to appreciate its value, you may want to execute this tool on all your databases on a regular basis, so you can keep track of things for long periods of time. This tool is becoming part of a large collection of goodies many DBAs use today.
During this session you will learn the basics about the free eDB360 tool, plus some cool tricks. The target audience is: DBAs, developers and consultants (some managers could also benefit).

Oracle GoldenGate and Apache Kafka: A Deep Dive Into Real-Time Data StreamingMichael Rainey
We produce quite a lot of data! Much of the data are business transactions stored in a relational database. More frequently, the data are non-structured, high volume and rapidly changing datasets known in the industry as Big Data. The challenge for data integration professionals is to combine and transform the data into useful information. Not just that, but it must also be done in near real-time and using a target system such as Hadoop. The topic of this session, real-time data streaming, provides a great solution for this challenging task. By integrating GoldenGate, Oracle’s premier data replication technology, and Apache Kafka, the latest open-source streaming and messaging system, we can implement a fast, durable, and scalable solution.

DB Time, Average Active Sessions, and ASH Math - Oracle performance fundamentalsJohn Beresniewicz
RMOUG 2020 abstract:
This session will cover core concepts for Oracle performance analysis first introduced in Oracle 10g and forming the backbone of many features in the Diagnostic and Tuning packs. The presentation will cover the theoretical basis and meaning of these concepts, as well as illustrate how they are fundamental to many user-facing features in both the database itself and Enterprise Manager.
This is the presentation on ASH that I did with Graham Wood at RMOUG 2014 and that represents the final best effort to capture essential and advanced ASH content as started in a presentation Uri Shaft and I gave at a small conference in Denmark sometime in 2012 perhaps. The presentation is also available publicly through the RMOUG website, so I felt at liberty to post it myself here. If it disappears it would likely be because I have been asked to remove it by Oracle.
Understanding SQL Trace, TKPROF and Execution Plan for beginnersCarlos Sierra
The three fundamental steps of SQL Tuning are: 1) Diagnostics Collection; 2) Root Cause Analysis (RCA); and 3) Remediation. This introductory session on SQL Tuning is for novice DBAs and Developers that are required to investigate a piece of an application performing poorly.
On this session participants will learn about producing a SQL Trace then a summary TKPROF report. A sample TKPROF is navigated with the audience, where the trivial and the no so trivial is exposed and explain. Execution Plans are also navigated and explained, so participants can later untangle complex Execution Plans and start diagnosing SQL performing badly.
This session encourages participants to ask all kind of questions that could be potential road-blocks for deeper understanding of how to address a SQL performing poorly.

Percona xtra db cluster(pxc) non blocking operations, what you need to know t...Marco Tusa
Performing simple DDL operations as ADD/DROP INDEX in a tightly connected cluster as PXC, can become a nightmare. Metalock will prevent Data modifications for long period of time and to bypass this, we need to become creative, like using Rolling schema upgrade or Percona online-schema-change. With NBO, we will be able to avoid such craziness at least for a simple operation like adding an index. In this brief talk I will illustrate what you should do to see the negative effect of NON using NBO, as well what you should do to use it correctly and what to expect out of it.
In this first of a series of presentations, we'll overview the differences between SQL and PL/SQL, and the first steps in optimization, as understanding RULE vs. COST, and how to slash 90% response time in data extractions running in SQL*Plus.
SQL tuning An execution plan is the output of the optimizer and is presented to the execution engine for
implementation. It instructs the execution engine about the operations that it must perform for
most efficiently retrieving the data required by a query.
The EXPLAIN PLAN statement gathers execution plans chosen by the Oracle optimizer for
the SELECT, UPDATE, INSERT, and DELETE statements. The steps of the execution plan are
not performed in the order in which they are numbered. There is a parent-child relationship
between steps. The row source tree is the core of the execution plan. It shows the following
information: • An ordering of the tables referenced by the statement
• An access method for each table mentioned in the statement
• A join method for tables affected by join operations in the statement
• Data operations, such as filter, sort, or aggregation
In addition to the row source tree (or data flow tree for parallel operations), the plan table
contains information about the following:
• Optimization, such as the cost and cardinality of each operation
• Partitioning, such as the set of accessed partitions
• Parallel execution, such as the distribution method of join inputs
The EXPLAIN PLAN results help you determine whether the optimizer selects a particular When you tune a SQL statement in an OLTP environment, the goal is to drive from the table
that has the most selective filter. This means that there are fewer rows passed to the next
step. If the next step is a join, this means fewer rows are joined. Check to see whether the
access paths are optimal. When you examine the optimizer execution plan, check to confirm
the following:
• The plan is such that the driving table has the best filter.
• The join order in each step means that the fewest number of rows are returned to the
next step (that is, the join order should reflect going to the best not-yet-used filters).
• The join method is appropriate for the number of rows being returned. For example,
nested loops joins through indexes may not be optimal when many rows are returned.
• Views are used efficiently. Look at the SELECT list to see whether access to the view is
necessary.
• There are any unintentional Cartesian products (even with small tables).
• Each table is being accessed efficiently. Consider the predicates in the SQL statement and the number of rows in the table. Look for suspicious activity, such as a full table
scan on tables with large number of rows, which have predicates in the WHERE clause.
Also, a full table scan might be more efficient on a small table, or to leverage a better
join method (for example, hash join) for the number of rows returned.
If any of these conditions are not optimal, consider restructuring the SQL statement or the
indexes available on the tables. There are many ways to retrieve execution plans inside the database. The most well known
ones are listed in the slide:
• The EXPLAIN PLAN command enables you to view the execution plan that the

SQL Server Query Tuning Tips - Get it Right the First TimeDean Richards
Whether you are a developer or DBA, this presentation will outline a method for determining the best approach for tuning a query every time by utilizing response time analysis and SQL Diagramming techniques. Regardless of the complexity of the statement or database platform being utilized (this method works on all), this quick and systematic approach will lead you down the correct
tuning path with no guessing. If you are a beginner or expert, this approach will save you countless hours tuning a query.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.
