Swingbench SwingBench can now be started to produce a transaction load and simulate an order-entry system and to test the replication.

This uses port forwarding which was setup when Virtual Box was configured (02 - Set up NAT network in Virtual Box). 192.168.1.197 is the IP address of the host machine (laptop). Use ifconfig or ipconfig to identify what the local IP address is of the host machine. |
2. Start charbench which is the character based version of swingbench.

| /u01/ 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.

[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

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. This simulation will take approximately 15 minutes.
| Note |
|---|
Your laptop has to be power 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.
