Hi,

Can you help me to understand why my dml (merge) is too slow ?

According to OEM reports :

1/ Table access full (TIERS) require many IO requests 5 460 ! is it normal ?

2/ What it means % CPU ACTIVITY= 62% (table access by local index rowid / index range scan) ?

3/ Index Unique Scan require many Waits: 67 %? Why?

4/ Index range scan require many wait activity too? Is it normal?

5/ Another suspicious operation?

SEE ATTACHED FILE PLEASE .

Best regards.

GD.
