Hello,

Suggest you ask something more specific.

There are many ways to connect to mainframe databases including odbc and jdbc. . .

If a COBOL+DB2+CICS program is there how the database will establish and how it will work.

Hello,

When running a COBOL+DB2+CICS all of the connectivity is local to the mainframe. There is no need for odbc, jdbc, etc. These are for "remote" connectivity from typically a non-mainframe environment.

Batch jobs and cics regions are connected directly to database systems.

1. Sign onto the mainframe
2. Sign onto CICS
3. Invoke the transaction, which runs the COBOL program load module
4. The COBOL program issues SQL calls to access the DB2 database

Details depend upon the application, the database, and what the program is supposed to do (inquire, update, delete data for example).
