Oracle Certification Guides

Oracle certification guides organized by OCI, Database, Java, and MySQL product families.

This section collects Oracle certification guides on TechExamLexicon.com using the same vendor-first shape as the IT Mastery practice routes: Oracle is the issuer, and product families such as OCI, Database, Java, and MySQL group the individual exam-code pages.

Oracle product families

Family	What it covers	Start here
Oracle Cloud Infrastructure	OCI foundations, architecture, security, operations, observability, DevOps, AI, data science, integration, and database-services routes.	1Z0-1122-25 or 1Z0-1127-25

1Z0-909	MySQL 8.0 Database Developer	Cheat Sheet
1Z0-1122-25	OCI AI Foundations Associate	Cheat Sheet
1Z0-1127-25	OCI Generative AI Professional	Cheat Sheet
1Z0-997-25	OCI Architect Professional	Cheat Sheet
1Z0-1084-25	OCI Developer Professional	Cheat Sheet

The Java 25-aligned 1Z0-831 guide is intentionally conservative about live Oracle exam-publication claims: it teaches the Java SE 25 platform and the expected next professional-Java lane, but its exact Oracle storefront and catalog status should be checked against Oracle-owned sources.

Start with the product family that matches your exam code, then use the exam guide for orientation, the study plan for pacing, the cheat sheet for final review, the FAQ for recurring questions, and the resources page for Oracle references.
