Step 5: Session Management (Admin Role)
If you have admin rights, you can also:
- View active sessions (filter by username, SQL ID, and so on).
- Identify stuck or long-running sessions.
- Use the provided interface or API to terminate safe-to-kill sessions (based on naming patterns like _RDS_CUSTOM).
Table 23-2 Interpretation Tips
Observation | Likely Cause / Next Step |
---|---|
High wait time on temp I/O | Queries spilling to disk → check joins/sorts |
One query dominates Top SQL | Regressed plan or unindexed access → tune it |
Lots of queued statements | Resource bottleneck (e.g., CPU) → throttle, tune |
Sharp spike in APEX load time | Backend slowness or DB resource saturation |
Session count far above normal | Application surge, leaking sessions, or blocking |
