The Accessing IMS Databases from COBOL course looks at the COBOL coding required to access an IMS database. It describes the DL/I commands and functions used to reference and manipulate IMS data, and shows how a simple COBOL program is written to perform such tasks. An overview of DL/I command codes and status codes is provided along with more detailed IMS database data manipulation techniques. The final module focuses on IMS database recovery methods and COBOL programming considerations.
COBOL Programmers who need to work with IMS databases.
The learner should have a solid knowledge of IMS database concepts and methods used to access an IMS database. This content can be obtained from the IMS Database course in the IMS curriculum.
After completing this course, the student will be able to:
- Describe how a COBOL program access an IMS database
- Code a COBOL program to reference and manipulate IMS database data
- Describe how IMS Database recovery is performed following a COBOL program error
