Process Monitor Developers: A Comprehensive Guide to Monitoring Sessions in Your RAC Instance

As a process monitor developer, you understand the importance of monitoring sessions in your Real Application Clusters (RAC) instance. With the 'Active Sessions' report in Oracle Enterprise Manager, you can now easily track and analyze the performance of your database. In this article, we will explore how to use this report to gain a deeper understanding of what's happening in your RAC instance.

The 'Active Sessions' report queries the GV$ view, providing valuable insights into sessions across your RAC instance, including plan details, bind variables, and v$session_longops. This information is essential for identifying bottlenecks and optimizing performance.

One of the key benefits of this report is its customizability. Once you've added it to your 'User Defined Reports' section, you can edit it to fit your specific needs. For example, if you want to include additional columns or filters, you can easily do so by modifying the report's SQL query.

However, some users may find the raw SQL output difficult to read due to its lack of carriage returns and extra spaces. Additionally, the v$session_longops view does not provide real-time information on tasks such as backup or index creation. To overcome these limitations, we recommend customizing the report to include only the most relevant data.

To get started with monitoring sessions in your RAC instance, simply navigate to the 'Tools' menu and select 'Monitor Sessions...'. From there, you can browse through the list of active sessions and drill down into details such as plan and bind variables. You can also use this report to identify bottlenecks by analyzing wait times, locks, and performance data.

In conclusion, the 'Active Sessions' report is a powerful tool for process monitor developers, providing valuable insights into the performance of their RAC instance. By customizing the report and leveraging its features, you can gain a full picture of what your users and applications are doing in the database.
