IBM Mainframe Forum

I want to code GDG for a particular person bank transaction for a year, at the end of each day the updated information has to be generated..How to code it? That person do daily transaction...How to generate GDG with updated information each day....kindly explain me the process and guide me with the coding..

Hello and welcome to the forum,

What you want to do is not clear. . .

Will every person that is a customer of the bank have an entire gdg for only themself? One of the banks i use has multiple million account holders. . .

The process is to DEFINE a GDG and then each time a new generation is created, it is cataloged by specifying (+1) in the JCL that creates the new generation.

If you are looking for something else, please clarify.

Hello,

Thought it was just me ...

Nope. . .

From the bit posted, it is my guess that this is not a good candidate for a GDG, but maybe some clarification will be posted. Recording transactions in a database surely comes to mind. . .

Thanks for ur reply dick..I am just a beginner in mainframe,please dont give negative comments by saying that i am not
a good candidate for GDG...Only by clarifing my doubts i can became strong in Mainframe.

You're welcome

First, you need to learn to be much less sensitive - especially until you learn much more about English communication. Your vocabulary looks good, but you completely missed the the intent of my last reply. Which leads to:

please dont give negative comments by saying that i am not

Second, the reply had nothing to do with you or your potential.

The reply was directed toward the initial "requirement". The "requirement" as posted does not fit with how GDGs are typically used.

Possibly you can clarify how your organization intends to manage these GDGs if one is assigned for every customer that opens an account. . .

Padma,

Phrasing a question properly is an art and that comes with experience. As you just experienced, reading and understanding is also an art and that also comes with exeperience.

I think what Dick meant was that you requirement is not a good candidate for GDG since typically a bank has millions of customers and you really don't want to define a GDG per customer.

A more clear question makes it easier to respond with a better answer.

It would be interesting to know whether there was database support such as IMS or DB2.

In our financial system, this type of transaction is stored in a db2 table as rows with a key that is a unique identifier for the customer, the date of the transaction, and a transaction type.

I would not recommend flat files or VSAM unless there is no database support.

This is just from financial system experience using both methods.

Good luck, though. Financial systems can be pretty tough to work on.
