| I have a cobol non db2 source pgm and it calls a db2 pgm. How different will be the compilation process from a normal cobol db2 compilation.Will there be a pre-compilation process ? |

No, you don't need a precompile for a program that does not access DB2 directly.

You will have to execute it like you execute a DB2 program (probably DSN RUN...)

| Could you please explain me how the bind will happen here. Or if you could explain me how exactly the compile and run would happen it would be of great help. |

You are making things complex while they are very simple:
Preparation
A DB2 program requires precompile, compile and bind.
A non-DB2 program requires only compile.
Execution
A DB2 program, or a program that calls a DB2 program, need to be invoked as a DB2 program, usually under DSN.

You need to start your program from the IKJEFT01 or similar TSO batch environment, or if your installation has IMS DB/DC, as a batch job in that environment.
Ask support personnel, or your colleagues for advice on this. You are presumably not the first to have a DB2 batch implemneted at your site. |

This is what i understood. Do correct me if i am wrong.
The main cobol pgm(CP1) will undergo a normal compile process and the db2 subprogram(DS1) will undergo the pre-complie,compile,bind process to generate the plan.Then in run jcl we need to give the main pgm name and plan name for execution. |
