How do you check the performance on an Oracle database?

To monitor throughput:

  1. From the Database Home page, click Performance. The Performance page appears.
  2. In the instance activity chart, click Throughput. The Throughput charts are shown with Instance Throughput Rate set to the default value of Per Second.

What is performance monitoring Oracle?

The Oracle Database makes it easy to proactively monitor the health and performance of your database. It monitors the vital signs (or metrics) related to database health, analyzes the workload running against the database, and automatically identifies any issues that need your attention as an administrator.

    Five Best Practices for Proactive Database Performance Monitoring

    1. Monitor Availability and Resource Consumption. This first step of proactive monitoring is to check whether all databases are online at regular intervals.
    2. Measure and Compare Throughput.
    3. Monitor Expensive Queries.
    4. Track Database Changes.
    5. Monitor Logs.

    How do I monitor my Oracle performance scripts?

    Then I will cover these eight important scripts for monitoring the Oracle database:

    1. Check instance availability.
    2. Check listener availability.
    3. Check alert log files for error messages.
    4. Clean up old log files before log destination gets filled.
    5. Analyze tables and indexes for better performance.
    6. Check tablespace usage.

    What is Oracle performance tuning?

    Performance tuning is the process of optimizing Oracle performance by streamlining the execution of SQL statements. In other words, performance tuning simplifies the process of accessing and altering information contained by the database with the intention of improving query response times and application operations.

    What should I monitor in Oracle database?

    With the System Statistics page of the Oracle Database XE graphical user interface, you can monitor the following types of database statistics:

    • Physical Input/Output (I/O)
    • Logical I/O.
    • Memory usage.
    • CPU time and wait events.
    • SQL cursors.
    • Transactions committed.

    How do you manage database performance?

    Monitor performance metrics such as top users, queries, programs, etc. Visualize end-to-end application performance right from the tools being used. Get alerts when set database thresholds are about to be violated. Visualize the SQL execution plans in order to isolate bottlenecks.

    How do I check SQL performance issues?

    Start by checking your wait stats

    1. Ensure your TempDB database is configured optimally.
    2. Make sure you’re running index maintenance frequently.
    3. Implement indexes that provide a benefit to your queries.
    4. Check your most expensive queries and stored procedures.
    5. Monitor your performance counters.
