The Oracle 1Z0-001 (Introduction to Oracle: SQL and PL/SQL) exam for the DBA 9i track is completely retired and no longer active. Oracle has officially phased out the Oracle 9i certification program.
Because Oracle continuously updates its technology, you cannot register for or take this specific exam. However, if you are looking to become an Oracle Database PL/SQL Certified Professional, you must transition to the modern equivalents. The current standard path requires passing the SQL baseline exam followed by the active PL/SQL professional exam.
To pass the modern equivalent track on your first attempt, follow this updated roadmap: 1. Master the Prerequisite: The SQL Associate Exam
Before you can earn your PL/SQL Professional credentials, you need to prove your baseline SQL fluency. The Exam: Take the Oracle Database SQL 1Z0-071 Exam.
Core Focus: This exam validates your depth of knowledge regarding SELECT queries, DDL/DML statements, tables, indexes, normalization, and the Oracle optimizer. 2. Prepare for the Modern PL/SQL Replacement Exam
The active replacement for historical PL/SQL testing is the 1Z0-149 (Oracle Database Program with PL/SQL) exam. To pass it on your first try, focus your studies heavily on these three core segments:
Declaring Variables & Identifiers: Master valid/invalid identifiers, bind variables, and declaring complex variable data types using the %TYPE and %ROWTYPE attributes.
Writing Executable Statements: Understand lexical units, implicit vs. explicit data conversions, nested blocks, and utilizing built-in SQL functions directly inside your PL/SQL expressions.
DML and Block Control: Learn how to write flawless procedural blocks utilizing Data Manipulation Language (DML) and transaction controls (COMMIT and ROLLBACK). 3. Strategy for First-Time Success
Because Oracle multi-choice questions are famously “twisted” and require deep syntax analysis within strict time limits, structural preparation is vital: Certification Question – Oracle Forums
