While most modern Oracle certifications focus on newer versions like Oracle Cloud Infrastructure (OCI) and Oracle Database 11g, some institutions and training centers still offer courses and certifications for Oracle 9i, particularly for database administration. The primary way to get certified is by passing the two required exams for the Oracle9i Database Administrator OCA credential: Exam #1Z0-007 (Introduction to Oracle9i: SQL) and Exam #1Z0-031 (Oracle9i Database: Fundamentals I). 

Training and certification for Oracle 9i

• Official certification exams: To earn the Oracle9i OCA credential, you must pass two exams:
• Exam #1Z0-007: Introduction to Oracle9i: SQL: This can be taken online.
• Exam #1Z0-031: Oracle9i Database: Fundamentals I: This is a proctored exam that must be taken at an authorized test center.
• Training courses: Many training providers, like National Council of Training Academy and Unisoft Technologies Nagpur, offer specialized courses to help you prepare for these exams. These courses can cover foundational concepts, SQL, PL/SQL, and the architectural components of the Oracle 9i database.
• Focus of the training: Courses typically focus on key areas such as:
• Database structure and storage (tables, columns)
• Writing and executing SQL statements
• Data manipulation and aggregation
• Database backup and recovery
• Security mechanisms
• Note: Oracle 9i is an older version. While some organizations still use it, most new development and certifications focus on newer versions. Some courses may be designed to "upgrade" skills from 9i to newer versions.
