I ran an SQL SELECT using hint key HINT_$PHY$ to do physical reads only but find that my index is still accessed.
z/OS CA Datacom 15.1
Table involved in the SQL SELECT resides in an area for which a BA24 (blocksize alter) process has been run. Once a BA24 process has been run, so even if that ended successfully , it is not possible to do physical sequential reading .
After running DBUTLTY BACKUP/LOAD all physical reads will be restored.
DEFECT DE370752 has been opened for the CBS Diagnostic report to reflect the use of physical data scan or not . And if not, for what reason.
