RAC node or<br />
proxy node<br />
The following image shows the processor utilization on a RAC node under the<br />
following conditions:<br />
• Swingbench load only<br />
• Swingbench load plus a backup running on the node<br />
• Swingbench load plus a clone sync<br />
This graph shows that using SnapView clones to create a copy of the production<br />
database significantly alleviates much of the backup overhead. The clone copy is<br />
mounted to the proxy host <strong>and</strong> the backup is then run from the proxy host.<br />
Line 1: shows the total CPU utilization on a RAC node under Swingbench load<br />
simulating a production-like load on the database.<br />
Line 2: shows the overhead incurred when running a backup on the RAC node<br />
concurrently with the Swingbench load.<br />
Line 3: shows the overhead incurred when creating a clone copy of the<br />
production database while running the Swingbench load.<br />
Pointer 4: is the point at which the clone sync commenced. This was an<br />
incremental sync.<br />
