Learning journey
A clearer learning flow.
The progression begins with Oracle architecture internals and database creation on Linux, advances through SQL and PL/SQL programming, Oracle Net, and storage and security administration, then moves into RMAN backup and recovery, Data Guard standby configuration, and RAC fundamentals, and finishes with Oracle Enterprise Manager, AWR/ASH performance tuning, and OCA/OCP exam preparation with a capstone enterprise DBA project.

Step 01
Oracle Architecture & Database Creation
Oracle Database 19c/21c installation on Linux; Oracle architecture — CDB/PDB multitenant model, SGA components (Shared Pool, Buffer Cache, Redo Log Buffer), PGA, and background processes (SMON, PMON, LGWR, DBWR, CKPT); Oracle Universal Installer (OUI); DBCA database creation; SQL*Plus and Oracle SQL Developer orientation.

Step 02
SQL, PL/SQL & Oracle Storage Management
Oracle SQL — DDL, DML, joins, subqueries, analytic functions, and Oracle-specific syntax; PL/SQL — blocks, procedures, functions, packages, cursors, exceptions, and triggers; tablespace management — system, undo, temp, and user tablespaces; datafile management and ASM storage basics; Oracle Net configuration — listener.ora and tnsnames.ora.

Step 03
User Security, Auditing & Database Maintenance
User management — CREATE USER, GRANT, REVOKE, profiles, and password policies; role-based access control and privilege management; unified auditing — configuring audit policies and log review; undo management and flashback technologies — Flashback Query, Table, and Database; redo log management; and Oracle alert log monitoring.

Step 04
RMAN Backup, Data Guard & RAC Fundamentals
RMAN architecture and configuration — backup sets, image copies, retention policies, incremental backups, and recovery catalogue; complete and point-in-time database recovery; Oracle Data Guard — physical standby setup, log transport, switchover and failover; Real Application Clusters (RAC) — architecture, interconnect, and administration basics; and Oracle GoldenGate concepts.

Step 05
OEM, AWR Performance Tuning & OCA/OCP Capstone
Oracle Enterprise Manager (OEM) Cloud Control — installation, monitoring, and alerts; AWR, ASH, and ADDM report generation and interpretation; SQL execution plan analysis — EXPLAIN PLAN and SQL Tuning Advisor; memory and I/O performance tuning; database patching with OPatch; OCA (1Z0-082) and OCP exam syllabus coverage; and a full enterprise Oracle DBA capstone project.
