If all is configured correctly when running either our Tcl or Python driver script we will see output such as follows, note that Vuser 2 shows FINISHED SUCCESS just after it starts so the only activity that this script is doing on the database is capturing the NOPM and TPM over a time period, in this example 2 minutes. $./hammerdbcli

Back in the Dim And Distant Past of 2003 I even co-led an open source project that brought some at-the-time interesting innovations to this area. Continuous Integration and Continuous Delivery (CI/CD) are techniques that I’ve had a passion about for a long time. Most of the basic and medium functionality is covered.

When taking this approach you would not focus on the test result but instead monitor the databases ability to cope with the variation in demand and transaction response times. This is because Virtual User 1 is the monitor Virtual User but this Virtual User does not run in the replica meaning it ends immediately. Step Workloads.

Allan also introduced me to Richard McDougall, who had worked with Allan for Sun Australia, and Richard visited for a rotation to build some monitoring tools.
