Hi,

We are currently providing support for a large legacy application developed mainly in COBOL, JCL and DB2. Recently, there is a move to migrate the IMS DBD/GSAM/PSB sources from IBM's Data Dictionary to Endevor. What IMS DBD/GSAM/PSB ? That is something that I have no idea. The only thing I know about IMS/DB is that it is a hierarchical database as opposed to DB2 which is relational.

We would like to determine what would be the impact of this change to our system. Off the top of my head, I know we don't use IMS/DB but that is something that I cannot tell for certain at this time since I remember discovering a module invoking a Assembler module several months back.

Any idea on how to check? Say, Endevor search? But what do I search for?

Pls advise.


Thanks,

I suggest that if these ims components exist and are to be moved to Endevor, ims is being used. . . somewhere. . .

but given the confusing way the question is posed anything we might suggest
is pure speculation...

Hi,

I can say one thing. As far as i know, if IMS DB has been used in the COBOL programs, it can be found as follows:

Example:

Code:


PROCEDURE DIVISION.

ENTRY ‘DLITCBL’ USING DB-PCB-1, DB-PCB-2.

............
............

Call 'CBLTDLI' using WS-PARM-COUNT, <-------- OPTIONAL
                     WS-FUNCTION-CODE,
                     DB-PCB-MASK,
                     IO-AREA,
                     SSA-1, SSA-2, SSA-3,..

..............
..............



I don't know how to use search option in Endevor. You can use the word 'DLITCBL' or 'CBLTDLI' as key word for search.

Hope this bit helps.

Cheers
Agni.

Thanks for that Agni. That was helpful. I can now rest and say that we are not using IMS :-)
