SwingBench can now be started to produce a transaction load and simulate an order-entry system to test the replication.
| Note |
|---|
Start a new terminal session on the source server, as oracle. |
- In the $HOME/replicate directory, execute the run_swingbench.bash script to start the charbench utility which is the character based version of SwingBench.
| No Format |
|---|
[oracle@source ~]$ cd $HOME/replicate
[oracle@source replicate]$ ./run_swingbench.bash |
The command that will be executed by the script is a very simple one... you can do this on the command line instead of running the script.
#/bin/bash
# -cs <connect_string>
# -u <schema_user>
# -p <schema_user_password>
# -uc <simulated_user_count>
# -min <min_transaction_think_time_in_milliseconds>
# -max <max_transaction_think_time_in_milliseconds>
# -rt <runtime_hh:mi>
# -a run automatically
# -v display run statistics
/u01/app/oracle/swingbench/bin/charbench -cs //source/XE -u repoe -p repoe -uc 10 -min 5 -max 200 -rt 0:10 -a -v
The output will be similar to the following and will run for 10 minutes. A total number of 10 users will be simulated.

| Tip |
|---|
If you want to stop SwingBench before the 10 minutes is up, just hit Ctrl C in the terminal window where it's running to interrupt it. While the SwingBench is running - keep an eye on your dbvisit console (The dbvisit console should still be running. if not restart the dbvisit console on the source server - cd $HOME/dbvrep_XE and ./start-console.sh )
|
| Note |

It is easy to change the parameters of swingbench to change the load and the time that it runs. The parameters are:
All command line options are listed here |
3. Optional. Swingbench is highly configurable. The load on the system can be easily increased. In this example, the number of users is set to 40 and the min and max delay is shortened. As a result the TPS peaks at over 400 transactions per second.
| Note |
|---|
Your laptop has to be powerful enough to handle this load and a large number of archived redo logs will be generated that may fill up the disk space. |

Right, that should have given the replication something to do. Lets return to the Replication Console and see what's happening.When we successfully installed DBVisit Replicate product on our RepAttack environment, we should test, how the replication works itself.
This chapter brings some basic examples, that should demonstrate the user how the logical replication works, how are the replicated DMLs transformed, how to use and monitor replicate and how to setup some basic features of replicate such as filtering rows and excluding columns.
