Scenario: During peak hours, several users report slow query performance. How can the DB2 administrator identify the cause and resolve the issue promptly?
- Disable unnecessary applications to reduce system load
- Enable monitoring tools to capture SQL performance metrics
- Increase hardware resources such as CPU and memory
- Restart the DB2 instance to clear any temporary bottlenecks
Enabling monitoring tools to capture SQL performance metrics allows the DB2 administrator to identify poorly performing queries during peak hours. These tools can provide insights into various metrics such as execution time, I/O operations, and locking behavior, enabling the administrator to pinpoint the cause of slow query performance. Increasing hardware resources or restarting the DB2 instance may provide temporary relief but may not address the root cause of the issue. Disabling unnecessary applications can reduce system load but may not directly address SQL performance concerns.
