During a load test a query was found to be slowly executing. It is the index that is causing it to perform poorly.
It's a system generated query as can be seen from the corresponding AWR and query ID.
Two workarounds were tried:
1. Add an index hint
2. Drop the index altogether
The 1st option can't be used since it is a system generated query and it's not known how it will take the index.
The 2nd option - dropping the index - showed a good result in the test, the execution time was drastically reduced.
