Kursbeskrivning: Advanced Programming for DB2 z/OS

This is the classroom version of Instructor Led Online course 3V770.

This course provides lectures and hands-on lab exercises for the advanced application developer in a DB2 for z/OS environment.

You are expected to apply the knowledge acquired in this course to code and prepare high performing concurrent, static and dynamic programs supporting a local, remote, or distributed DB2 environment. An array of topics are taught which facilitates the coding and the maintenance of programs to enable you to write multi-purpose flexible programs that process large objects, use stored procedures, scroll through result sets, interact with the web, improve the usability of an application, use tools verses writing an application, and debug an application using the IBM Debug Tool.

This advanced course is for the classical COBOL or PL/I mainframe programmer and C, C++ programmer with an interest in advanced topics and recommended practices to code and prepare high performing programs in a DB2 for z/OS environment. The programs in the lab exercises are pre-coded using COBOL; the student must only supply the DB2/SQL specifics.
