Oracle Database 19c: ASM Administration Workshop — Lesson 2: ASM Files, Templates, Aliases, Directories, and ACFS Awareness

Learning Objectives

• Explain the architecture, workflow, or business purpose behind ASM file types, naming, aliases, directories, and file placement.
• Apply templates, redundancy, striping, and file creation attributes and database, control, redo, archive, backup, and temporary files in a controlled scenario.
• Validate outcomes and troubleshoot risks involving ADVM and ACFS concepts, use cases, boundaries, and operational ownership.

Detailed Topics

• ASM file types, naming, aliases, directories, and file placement
• templates, redundancy, striping, and file creation attributes
• database, control, redo, archive, backup, and temporary files
• ADVM and ACFS concepts, use cases, boundaries, and operational ownership

Instructor Demonstration

Demonstrate ASM file types, naming, aliases, directories, and file placement within an ASM storage estate expanded and rebalanced while protecting redundancy, performance, and database availability, then capture the exact configuration, command, transaction, report, model, query, code, or process evidence that proves the result for lesson 2.

Hands-On Exercise

Implement a controlled exercise covering templates, redundancy, striping, and file creation attributes and database, control, redo, archive, backup, and temporary files, then introduce and resolve an exception involving ADVM and ACFS concepts, use cases, boundaries, and operational ownership while preserving before-and-after evidence.

1. Confirm the environment, identities, inputs, dependencies, risks, and expected outcome.
2. Complete the course-specific configuration, development, analysis, or process workflow.
3. Capture settings, commands, data, outputs, logs, reports, screenshots, calculations, or test results.
4. Compare the observed result with acceptance criteria and document corrective action.

Scenario Analysis

• Identify the technical or business decision that must be made.
• Compare valid approaches and their security, performance, reliability, cost, compliance, and support trade-offs.
• Define rollback, recovery, ownership, communication, and evidence requirements.

Troubleshooting Guidance

Diagnose issues across ASM file types, naming, aliases, directories, and file placement, templates, redundancy, striping, and file creation attributes, database, control, redo, archive, backup, and temporary files, ADVM and ACFS concepts, use cases, boundaries, and operational ownership without making an unverified production change. Separate symptoms from causes, gather evidence, test the smallest reversible correction, rerun validation, and record preventive action.

Validation Checklist

• The requirement, scope, inputs, dependencies, and expected result are documented.
• The result is reproducible and supported by course-specific evidence.
• Normal, boundary, failure, security, performance, and operational conditions are reviewed.
• Exceptions, rollback, ownership, and the next improvement priority are recorded.

Lesson Outcome

Learners can apply ASM Files, Templates, Aliases, Directories, and ACFS Awareness in a realistic Oracle Database 19c: ASM Administration Workshop scenario and validate the result with documented evidence.
