Oracle Drivers configuration for High Availability, is it a developer's job?Ludovico Caldara
UCP, GridLink, TAF, AC, TAC, FAN… The configuration of Oracle Drivers for application high availability is not an easy job. The developers often care about the minimal working configuration, while the DBAs are busy with the operations. In this session I will try to demystify application server’s connectivity to the database and give a direction toward the highest availability, using Real Application Clusters and new Oracle features like TAC and CMAN TDM.
AskTom: How to Make and Test Your Application "Oracle RAC Ready"?Markus Michalewicz
Oracle Real Application Clusters (Oracle RAC) is the preferred availability and scalability solution for Oracle Databases, as most applications can benefit from its capabilities without making any changes. This mini session explains the secrets behind Oracle RAC’s horizontal scaling algorithm, Cache Fusion, and how you can test and ensure that your application is “Oracle RAC ready.”
This deck was first presented in OOW19 as an AskTom theater / mini session and will be presented as a full version in other conferences going forward at which time I will provide an updated version of the deck.

Linux and Open Source Software have always played a crucial role in data centers to provide storage in various ways. In this talk, Lenz will give an overview of how storage on Linux has evolved over the years, from local file systems to scalable file systems, logical volume managers and cluster file systems to today's modern file systems and distributed, parallel and fault-tolerant file systems.
Write Less (code) With More (Oracle Database 12c New Features)Oren Nakdimon
Oracle 12c introduced many new features that allow us developers to write less code than in previous releases, and become more efficient and productive.
Some features, such as Row Limiting and Lateral Inline Views, enhance the SQL language, so SQL statements can become much shorter and more readable than before.
Other features, such as Temporal Validity and In-Database Archiving, offer built-in functionality that previously had to be implemented by the application.
Attend this session to learn about several of these new features, and see many useful examples.
In-depth overview of Oracle Real Application Clusters (RAC) 12c Release 2, which was first presented during UKOUG Tech16 under the title "Under the Hood of Oracle Real Application Clusters (RAC) 12c Release 2" and before Oracle Database 12c Release 2 became generally available (GA) in March 2017.

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.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle.
Gopinath Rebala
Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.
