View data as it existed at a specific time in the past using the AS OF clause.
Portable collections of schemas and tablespaces that appear to applications as a standalone database. 2. Installing and Creating the Database
Revert a table to a prior state to fix localized user errors.
A Lab That Became Real On the penultimate day, the final lab asked them to architect a resilient system for a hypothetical company, Northwind Electronics, which needed high availability, automated patch management, and a secure backup strategy. The guide supplied a framework and suggested templates: a Fleet Patching plan, Data Guard configuration notes, and RMAN retention policies. Maya’s team sketched diagrams, referenced the guide’s sample scripts, and argued over whether to use physical standby or snapshot standby for their reporting needs.
This workshop provides comprehensive training on the architecture and its administration. It is designed to equip DBAs with the skills required to install, configure, manage, and troubleshoot Oracle databases in various environments, including cloud, on-premises, and engineered systems. Key areas covered in the workshop include: Installing and configuring Oracle Database 19c. Managing database instances and storage structures. Configuring the Oracle Network environment. Managing database security and user access. Implementing backup and recovery procedures using RMAN . Monitoring performance and managing database resources. Why You Need the Updated 19c Administration Guide
An Oracle instance consists of the memory structures and background processes.
: The workshop introduces basic techniques, including using RMAN for reliable data protection.
He came across a highlighted section on and Pluggable Databases (PDBs) . The guide detailed a specific recovery scenario he hadn’t practiced. If the PDB failed to open due to a metadata mismatch after the final migration script, the entire company’s shipping manifest would go dark.
The guide introduces the Cost-Based Optimizer (CBO). DBAs learn to gather optimizer statistics using the DBMS_STATS package, ensuring the database chooses the most efficient execution paths for complex SQL queries. 5. Backup, Recovery, and Flashback Technologies
