Unusual sqlt result

edited Jul 15, 2018 9:32AM in SQL Performance (MOSC) 5 commentsAnswered ✓
Hi, I am attempting to tune a query that uses a dblink. I ran sqlt on it and I got the following:

Index referenced by an Execution Plan does not exist.

If a Plan references a missing index then this Plan cannot be generated by the CBO. The index may had been just suggested by the STA or maybe it was dropped.

The index (all 3) in question does exist and is valid. I have not been able to get anything on the knowledge base of the internet on this issue. I have never seen it even tuning other queries that go accross a dblink. Any ideas? I tried sqlt on the other database but the id doesn't seem to be in the lib cache or awr.

Howdy, Stranger!
