This document discusses Oracle Data Guard and its functions. It provides information on different Data Guard configurations like physical and logical standbys. It describes features of Data Guard 11g like snapshot and active Data Guard. The benefits of physical and logical standbys are outlined. Tips are provided on tasks like running backups on a physical standby, tracing the apply process, bulk updates, reinstantiation of tables, and skipping transactions.
Oracle Real Application Clusters 19c- Best Practices and Internals- EMEA Tour...Sandesh Rao
In this session, I will cover under-the-hood features that power Oracle Real Application Clusters (Oracle RAC) 19c specifically around Cache Fusion and Service management. Improvements in Oracle RAC helps in integration with features such as Multitenant and Data Guard. In fact, these features benefit immensely when used with Oracle RAC. Finally we will talk about changes to the broader Oracle RAC Family of Products stack and the algorithmic changes that helps quickly detect sick/dead nodes/instances and the reconfiguration improvements to ensure that the Oracle RAC Databases continue to function without any disruption
With the Oracle Multitenant option of Oracle Database 12c, the services of individual pluggable databases (PDBs) can be opened selectively on specified nodes of an Oracle Real Application Clusters (Oracle RAC) cluster. A true symbiotic relationship: the Oracle Multitenant option makes Oracle RAC better, and Oracle RAC makes the Oracle Multitenant option better! UPDATE for IOUG 2014.
Oracle RAC - A Safe Investment into the Future of Your ITMarkus Michalewicz
This presentation reviews the evolution of Oracle RAC, the problems that it solves and the challenges that it faced. It also includes a high level outlook of the future development of Oracle RAC for you to realize that this isn't the first time that the benefits of Oracle RAC were challenged and yet no new technology was entirely able to solve all the problems it solves, while RAC has always successfully tackled the challenges with which it was faced.

Data Mobility for the Oracle Database by JWilliams and RGonzalezMarkus Michalewicz
With cloud computing, on-premises virtualization, and converged infrastructures, change is a constant. While relocating CPU cycles from on-premises to the cloud is easy, ensuring that data associated with the workload is available is quite difficult. This is the data mobility challenge. The latest generation of Oracle Automatic Storage Management (ASM) and Oracle Automatic Storage Management Cluster File System (ACFS) is designed to meet this challenge and this presentation is showing you how.
Oracle Database 19c, builds upon key architectural, distributed data and performance innovations established in earlier versions Oracle Database 12c and 18c releases. Oracle 19c has many new features, in this presentation we have covered below areas

Oracle Cloud is Best for Oracle Database - High AvailabilityMarkus Michalewicz
This presentation looks behind the covers and evaluates the offerings provided by various cloud vendors and compares them to the Oracle Database offerings available in the Oracle Cloud. The comparison includes Oracle Database in general, focusing on High Availability (HA) and Disaster Recovery (DR), as those areas have historically distinguished the Oracle Database from other databases and will likely continue to be some of the most distinguishing features when it comes to operating the Oracle Database in the cloud.

Performance Update: When Apache ORC Met Apache SparkDataWorks Summit
Apache Spark 1.4 introduced support for Apache ORC. However, initially it did not take advantage of the full power of ORC. For instance, it was slow because ORC vectorization was not used and push-down predicate wa s also not supported on DATE types. Recently the Apache Spark community has started to use the latest Apache ORC which include new enhancements to address these limitations. In this talk, we show the result of integrating the latest Apache ORC and Apache Spark. We will also review the latest enhancements and roadmap.

Migrating your clusters and workloads from Hadoop 2 to Hadoop 3DataWorks Summit
The Hadoop community announced Hadoop 3.0 GA in December, 2017 and 3.1 around April, 2018 loaded with a lot of features and improvements. One of the biggest challenges for any new major release of a software platform is its compatibility. Apache Hadoop community has focused on ensuring wire and binary compatibility for Hadoop 2 clients and workloads.
There are many challenges to be addressed by admins while upgrading to a major release of Hadoop. Users running workloads on Hadoop 2 should be able to seamlessly run or migrate their workloads onto Hadoop 3. This session will be deep diving into upgrade aspects in detail and provide a detailed preview of migration strategies with information on what works and what might not work. This talk would focus on the motivation for upgrading to Hadoop 3 and provide a cluster upgrade guide for admins and workload migration guide for users of Hadoop.

Today, many businesses around the world are using an Oracle product and in many of these at the core there is an Oracle Database. Many of us who started as a Database administrator where put in this position because we were good PL/SQL programmers or good Sysadmins, but knew very little of what it took to be a DBA. In this session you will learn the core architecture of an Oracle Database in 12c as well as what it takes to administer and apply this new knowledge the day you go back to your office.
Better, faster, cheaper infrastructure with apache cloud stack and riak cs reduxJohn Burwell
Software is eating infrastructure. Migrating reliability and
scalability responsibilities up the stack from specialized hardware to software, cloud orchestration platforms such as Apache CloudStack (ACS) and object stores such as Riak CS increase the utilization and density of compute and storage resources by dynamically shifting workloads based on demand. Together, these platform can saturate compute and storage of 1000s of commodity hosts with strong operational visibility and end-user self-service.
This presentation explores cloud design strategies to achieve high availability and reliability using commodity components. It then applies these strategies using Apache CloudStack and Riak CS.

Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
