Issue/Introduction

 

Question: 

When user looks at the data for a given collection id in DETECTOR SQL Table Activity Display , he only sees data for the associated qualified table, but the display is missing information about I/O against SPTR, which used to be displayed. Is this an expected behavior and that they should not expect to see I/O against SPTR? If so, is the data for SPTR I/O stored somewhere else?

 

Here is an example of a before and after view:

Answer: 

Regarding the concern about the STPR table not showing up under PSA, here is the explanation:

STPR table is internal to DB2 and DB2 accesses it and it is not accessed by the applications. So it’s okay to not see the I/O against that table since it is not attributed to the application.
