Debug Workflow for CCO (CloudConnect Optimizer)

Select Beserver in SGmon. It collects basic information related to the CCO job. The highlighted  text implies important debug messages one should look for while troubleshooting CCO. Once the job is ready to run, beserver firsts check the currently active CCO jobs, backup jobs and devices it targets. Based on this, it decides whether to run CCO, or fail.

The excerpt shows the starting of the test execution. For this, the job provider is Amazon. It starts the test with 1024 because the maximum write connection value for Amazon is 1024. It updates xml. Hence, it is better when the CCO job is running if no backup job is running as it may happen to use these test connections value.

The DLL generates data and starts writing to the OST image.

The DLL executes a number of tests and finally comes up with the suggested value. Once done with tests, it deletes the OST image created. It logs all the write connections values and corresponding throughput. The Server sends a VSN to update the default settings.
