Hi All,
I am receiving high expensive SQL statements alerts for the object SWWWIHEAD in EWA report continuously in one of our PI 7.3 box,
I have checked the SQL statement which is using more I/0 (40 %) and CPU (2%), below is the select statement which it's using. Can you please let me know me know the possible root cause for the issue and also any issue in the below query ? I have gone through few notes 881187 & 1024505 but those are not helping to tune this performance issue, as per the note 881187 the indexes for the table already exist in our system.
Please let me know if you need more logs or information on the same.
