I have an issue where I need to capture the datastream from a CICS program. I know the transaction. All I have are the loadlibs. What I would like to do is write a program to recognize the trancode and capture the datastream. Then write to a VSAM file. I have never tried somethng like this, any ideas? Thanks Texas programmer.

TX-programmer,

Capturing a data stream isn't that easy. Since you only have the loadlibs instead of the actual program you cannot issue RECIEVE BUFFER commands.

You can use the CICS Bridge facility to capture the datastream.

Check this link which explains in detail about Bridging to 3270 transactions

Hope this helps...

Cheers

You can also use FEPI (Front End processing interface), which 'front ends' any CICS terminal based transaction and intercepts the 3270 datastream. It's probably more complex than using the bridge facility but I think there are some restrictions on the bridge facility which don't apply to FEPI. FEPI has its own manual, available via this board's manual links.

Finally, there are some supplied products which do these sort of captures - e.g. Compuware's Hiperstation product. This could be ideal if you already have one of these products installed, or if you've got some spare cash in the software budget.
