When dealing with Oracle 19c Real Application Clusters (RAC), the process of capturing a workload from a source Oracle 19c RAC database and replaying it on a target Oracle 19c RAC database using HammerDB involves some additional considerations. Below are the revised steps:
Capture and Replay Workload from Source to Target Oracle 19c RAC
Go to the “Session” menu and select “Define Database.”
Choose “Oracle” as the database type.
For RAC, enter connection details for one of the nodes in the target Oracle 19c RAC cluster:
Hostname: <Node 1 hostname>
Port: <Oracle port>
Service Name: <Target Oracle service name>
Username: <Your target Oracle username>
Password: <Your target Oracle password>
Configure Replay on Target Database:
In the “Session” menu, select “Define Workload.”
Choose “Replay Workload.”
Specify the replay options, load the previously saved captured workload file, and configure the target Oracle 19c RAC database connection.
Run Load Test on Target Database:
Start the load testing by selecting the “Run Benchmark” option in HammerDB.
Monitor the progress of the test, which now replays the captured workload on the target Oracle 19c RAC database.
Review the detailed performance metrics and statistics provided by HammerDB after the load test completes.
Analyze the impact of the replayed workload on the target Oracle 19c RAC database.
These steps are tailored for Oracle 19c RAC. Always refer to the official documentation for accurate and up-to-date information, and ensure that you have the necessary permissions and licenses for performing load testing on both Oracle 19c RAC databases.
