LAD - GroundBreakers - Jul 2019 - Using Oracle Autonomous Health Framework to...Sandesh Rao
This session will focus on the best practice use of the Oracle Autonomous Health Framework (AHF) with an emphasis on troubleshooting private cloud database deployments. It will cover the troubleshooting tips and tricks which DBA's need on a daily basis using tools like Trace file Analyzer (TFA) , Exachk (Best Practices) , Cluster Health Advisor.. Additionally, use cases focusing on best practices for targeted diagnosis and rapid recovery to preserve availability will be covered. This will also cover the new troubleshooting tips for Oracle Database 19c

This presentation is based on Lawrence To's Maximum Availability Architecture (MAA) Oracle Open World Presentation talking about the latest updates on high availability (HA) best practices across multiple architectures, features and products in Oracle Database 19c. It considers all workloads, OLTP, DWH and analytics, mixed workload as well as on-premises and cloud-based deployments.
A Deep Dive into ASM Redundancy in ExadataEmre Baransel
Exadata Database Machine provides a solid storage redundancy infrastructure using ASM. Physical disks on multiple storage cell servers are logically partitioned, grouped and managed centrally by ASM. The way Exadata uses ASM has its own rules. The new term "Grid disk", ASM background processes, failgroups, redundancy options differ from non-Exadata systems. This storage configuration may sometimes seem to be complicated to Exadata Database Machine administrators. It's important to be able to answer the following questions, which are the topics of this presentation:
To what degree, disk and cell failures are tolerated;
How to understand if ASM is able to re-build redundancy after disk or cell failures;
What happens when multiple disks are failed at the same time and does it matter which disks failed;
What we need to pay attention to in terms of redundancy, when we do administrative task such as rolling restart of cell servers, resizing diskgroups, etc.
The AWS CLI provides an easy-to-use command line interface to AWS and allows you to create powerful automation scripts. In this session, you learn advanced techniques that open up new scenarios for using the AWS CLI. We demonstrate how to filter and transform service responses, how to chain and script commands, and explore new features in the AWS CLI.
