DB2 Z/os - Last used time

Postby p19689 » Thu Aug 25, 2011 2:20 pm

Hi , I would like to identify all the Views that haven't been used for last 24 months . The application was coded in COBOL and runs on DB2 Z/os V9. What is the best way to approach this task.

Select all
select distinct BQUALIFIER,BNAME,DNAME from sysibm.syspackdep where btype = 'V'

gives you all packages where the views are used.
Unfortunately the column lastused in syspackage is not yet maintained in db2 v9.
Unless you have SMF history of monitor trace 7 there is no info in db2 when a package was last used.
I can explain it to you, but i can not understand it for you.

Thanks GuyC, What you are suggesting is to go through the recently used packages and identify the views from them as there is no direct way to do that ?
