Oracle database administrators who perform performance tuning operations need to be familiar with the aspects of the database which indicate issues or problems. Interviewers will ask you about these to ensure that you recognize these signals and know how to respond to them. They're likely to ask you about the issues the organization has already encountered or are likely to encounter based on the structure of their Oracle database.

When responding to the interviewer's question about what indicators you can expect related to a specific issue you are likely to encounter with the Oracle database, make sure you include all of the signals you may encounter. In some cases, these may be limited to only one indicator, while in others, there may be multiple signals indicating that a specific action needs to be taken. This is an exception to the rule of keeping your answer direct and to the point. You should provide all of the possible scenarios related to this issue.

"There are several indications that the SHARED_POOL_SIZE parameter needs to be increased., These include Poor data dictionary or library cache hit ratios and getting error ORA-04031. Another indication is steadily decreasing performance when all the other tuning parameters are the same."
