COBOL DB2 programming to store & access JSON

I am new to DB2 and working on a requirement to store the JSON data after service call request and retrieve back the JSON data for analytical purposes.

I was searching for sample COBOL/DB2 programming for JSONs like DCLGEN declarations, host variable definitions, processing details, download the data from table etc…May be the key words I used, did not hit for the right page. Requesting you guys if you can route me to the right place.
