After the DRX Configuration File is created, it is ready to start replication. You can start replication by starting (up) the replication resource with the following commands.
Startup of resources provides a way to start all resources in the configuration file at once with control over the DRX services already prepared during installation or individually through a command-type utility. The following is a description of this
...
The way users change the contents of a configuration file and restart resources is called a static change settings.

| base-dir | DRX_PATH (Env variable) | Set the default route. |
| drbd-conf | DRBD_PATH (Env variable) | Set the path of drbd. |
| connect-timeout | 10 | Connection timeout |
| bwlimit | 0 | Bandwidth limitations on the network. 0 is unlimited and can be set to K, M, G (Unit Bytes Per Seconds) |
| loglevel-file | info | Log level to write to file |
| loglevel-stdout | info | The log level to output to the console when running foreground |
| logfile-max-size | 10M | Maximum size of log file |

5.3.2. Dynamic Change Settings
Using the drx-ctl set command to change real-time settings during operation is called dynamic setting change. Settings through the set command are temporary, not reflected in the contents of the actual resource configuration file.
