That seems to make sense, looks like I'll need to approach the problem from
a direction direction.

Thanks for the help

Best regards

Jonathan,

This one caught my eye so I thought I'd try to figure it out.  The one thing
I came across doing a Google search is a cover letter for PTF MF22430.
Here's a description of the problem fixed:


DESCRIPTION OF PROBLEM FIXED FOR APAR MA20199 :
-----------------------------------------------
  Provide a means for a customer to get the I/O for database
  records initiated prior to the application accessing them.
  This is the underlying support for QDBBRCDS API.

CORRECTION FOR APAR MA20199 :
-----------------------------
  I/O wait times may be reduced by using the QDBBRCDS API.
  See the API documentation for description and interface details.


>From reading this I'm thinking the API is used as a pre-fetch in your
application to get records into a record cache in order to enhance
performance in your application.

Subject: API to retrieve data field contents

Hi

Has anybody had any experience of using API's to retrieve the contents of PF
fields?  I've been looking at the API documentation, and the only one that I
can find that looks like what I need is QDBBRCDS.  The description says
about bringing the records into main storage, and only provides input
parameters for the records you want.  How do you reference the records
afterwards as there's no pointer or anything returned by the API?

Any advice would be gratefully received.

Thanks

Jonathan Mason
