[?] Informix Certifications

Greetings, I'm in the process of preparing to pursue various Informix certifications. Rather than take Informix's recommended courses for the Database Specialist Certification I'd like to study on my own. There are two exams necessary for this certification: 1 - Database Fundamentals Exam (consisting of Relational Database Design and SQL) 2 - Managing & Optimizing INFORMIX-Online Dynamic Server Databases Exam My tentative plan is to study through the 1 - Informix Guide to SQL Tutorial & Informix - SQL User Guide What do I need to study and review for the second exam? Informix - OnLine Administrator's Guide? Informix DB-Access User Manual? What else would be helpful in this regard? Any and all advice here is a greatly appreciated. Max Pyziur pyz@panix.com
