The Ultimate Guide to the Oracle Database 19c Administration Workshop Student Guide (PDF)

11. Recovery Scenarios and Practice Exercises

  • Scenario A: Crash recovery after instance failure — use automatic recovery on startup.
  • Scenario B: Media recovery after dropped datafile — perform RESTORE/RECOVER.
  • Scenario C: Point-in-time recovery (PITR) — use SET UNTIL TIME/FSCN and incomplete recovery, open with RESETLOGS.
  • Example PITR:
    • RMAN> RUN SET UNTIL TIME "TO_DATE('2026-03-10 14:30:00','YYYY-MM-DD HH24:MI:SS')"; RESTORE DATABASE; RECOVER DATABASE;
    • SQL> ALTER DATABASE OPEN RESETLOGS;

What is the Oracle Database 19c Administration Workshop?

The Oracle Database 19c Administration Workshop is an official, instructor-led training course (course code: DBA Admin I & II) offered by Oracle University. It is designed to equip DBAs with the skills needed to install, configure, manage, troubleshoot, and secure an Oracle 19c database.

The Student Guide PDF is the digital version of the courseware distributed to attendees of this workshop. It typically spans two volumes (Administration I and Administration II), totaling over 1,200 pages of concentrated, vendor-specific knowledge. The Ultimate Guide to the Oracle Database 19c

Key distinction: The "Student Guide" is different from the generic Oracle documentation library. It is structured for learning—with objectives, hands-on exercises, quizzes, and summary points—rather than pure reference. Scenario A: Crash recovery after instance failure —

Oracle Database 19c: Administration II (Focus: High-End Features & Tuning)

  • Automatic Storage Management (ASM): ASM instance, disk groups, mirroring, and rebalancing.
  • Multitenant Architecture: This is a massive emphasis in 19c. You will learn about Container Databases (CDBs), Pluggage Databases (PDBs), switching between PDBs, and cloning.
  • Resource Manager: Allocating CPU and sessions among different PDBs or consumer groups.
  • Backup and Recovery Using RMAN: Creating full, incremental, and cumulative backups; restoring data files, control files, and spfiles; using the RECOVER command; and enabling Fast Recovery Area (FRA).
  • Flashback Technologies: Using Flashback Database, Flashback Table, Flashback Drop, and Flashback Query for point-in-time recovery without full restoration.
  • Moving Data: Data Pump (expdp/impdp), SQL Loader, and external tables.
  • Performance Monitoring: Using Automatic Workload Repository (AWR), Automatic Database Diagnostic Monitor (ADDM), SQL Tuning Advisor, and real-time SQL monitoring.
  • Managing Performance Using SQL Plan Management: Capturing and evolving SQL baselines.

Strengths of the Student Guide

  • Hands-on, task-oriented approach — good for learning by doing
  • Includes sample scripts, configuration files, and lab step answers
  • Covers both basic administration and common real-world scenarios

5. Missing Modern DBA Topics

  • Zero coverage of:
    • Oracle Cloud (Autonomous Database, OCI CLI).
    • Multitenant container cloning (remote, refreshable PDBs).
    • Zero-downtime patching (RU, RUR, OPatch).
    • JSON or REST APIs for the database.
