Scenario: A DBA notices that a query is running slowly in DB2. Upon investigation, it is found that the table being queried does not have any indexes. What recommendation would you provide to optimize the query performance?

Adding indexes to the columns involved in the query can significantly enhance query performance by allowing DB2 to quickly locate the relevant rows. This reduces the need for full table scans and can lead to faster query execution. Rewriting the query might help in some cases, but adding indexes is a more direct solution to the problem of slow query performance due to the lack of indexes. Increasing server memory or partitioning the table may not directly address the issue of slow query performance caused by missing indexes.
