Oracle Database 19c: Administration Workshop — Lesson 1: Oracle Architecture, Instance Lifecycle, and Multitenant Context

Technical Scope

• SGA, PGA, processes, and database files
• startup stages and instance states
• CDB, PDB, containers, and services
• dynamic performance views and architecture verification

Instructor Demonstration

Demonstrate SGA, PGA, processes, and database files inside a new database moving from build to production support with capacity, connection, and health incidents, then capture the exact configuration, command, transaction, report, or code evidence that proves the result.

Applied Workshop

Implement a controlled workshop covering startup stages and instance states and CDB, PDB, containers, and services, then test a failure or exception involving dynamic performance views and architecture verification.

1. Confirm environment, identity, data, dependencies, and expected result.
2. Complete the product-specific implementation or analysis.
3. Capture commands, configuration, output, logs, transactions, or reports.
4. Explain the operational, security, performance, or business trade-off.

Validation Standard

The Oracle Architecture, Instance Lifecycle, and Multitenant Context result must be reproducible, traceable to approved inputs, and consistent with the expected Oracle product behavior.

• The intended target and ownership are verified.
• The result is supported by reproducible evidence.
• Security, performance, reliability, and support impact are reviewed.
• Unexpected behavior is investigated before acceptance.

Failure Analysis

Diagnose issues in SGA, PGA, processes, and database files, startup stages and instance states, CDB, PDB, containers, and services, or dynamic performance views and architecture verification without making an unverified production change.

Learners isolate the smallest proven cause, apply a reversible correction, rerun validation, and record the preventive action.
