How can I monitor and address fragmentation issues on RDS for Oracle database?

Amazon RDS for Oracle does not support the Automatic Fragment Advisor or the Automatic Segment Space Management feature of Oracle. However, RDS provides monitoring tools that can help you identify and address fragmentation issues.

One of the tools that RDS provides is the Oracle SQL monitoring feature, which allows you to monitor the SQL statements that are being executed on your database. This can help you identify SQL statements that are causing fragmentation issues, such as large insert or update statements. You can also use the Amazon RDS Performance Insights feature to monitor database performance and identify any performance bottlenecks.

In addition, you can use the Oracle Analyze Table command to gather statistics on table and index objects, which can help you identify fragmentation issues. You can also use the Oracle Segment Advisor to identify segments that are candidates for defragmentation.

It's important to note that Amazon RDS takes care of many of the administrative tasks associated with managing an Oracle database, such as backups, software patching, and hardware maintenance. However, it's still your responsibility to monitor the performance of your database and address any issues that arise.
