What are the different ways to run a COBOL DB2 program
using JCL? |

Hello,
You run them as directed by the system and database people. |

If your shop provides IMS DB/DC support, you can run batch jobs using IMS BMP or DBB environments.
Another common method is using the TSO environment which can be invoked in batch through the IKJEFT01 utility.
For details, look up the application planning manuals for DB2. |

| You will have to run your Cobol-DB2 program using the IKJEFT01 or 1B tool. Provide your program name and DB2 system name in the control card. |

Hello an welcome to the forum,

Not exactly true. . . There are also other ways that i'll not mention here.
When using an abbreviation (i.e. 1B) for some kind of add-on (not part of the basic product/environment) it is best to specify the full name rather than just the abbreviation. |

1B is not a special utility, just an abbreviated suffix for IKJEFTxx interfaces to invoke programs running in batch TSO/E envirionment.
There are in fact three alternate routines (entry points): IKJEFT01, IKJEFT1A, and IKJEFT1B, the difference being the way return codes and abends are handled by the interface |

And of course, CAF & RRSAF are another methods or running a DB2 application program.

For that, first you need to know - where to look at? And that's not an easy art, for sure! |

How common is CAF and RRSAF in batch applications? It is of cause site specific, but I have have never come across any implementations using these interfaces on the mainframes I have worked with.
The manual quotes some sample code for applications, but mostly in assembler. As I understand it, you will have to code the DB2 interface initialisation and termination yourself in an application, as opposed to the DB2 co-processor code that gets included in common DB2 interface programming. |

you are correct, you need to code the connect yourself. can be done in cobol, very easily.
I have used RRSAF in batch applications when using MQS and DB2. |
