Attributes
The table below provides description descriptions for the properties in the CPS.
Property | Description | |||||||
Chunk size | Number of bytes of Numberofbytesof the source file to be sent in each packet.
| |||||||
Source Directory | The directory from where the FileTransmitter picks the files to be transmitted. | |||||||
Start timeout | Transmitter sends a Start packet to know the existence of receiver(s). This timeout is the time (in milliseconds) to wait before resending a Start packet.
| |||||||
Packets per update | Number of packets to be sent Numberofpacketstobesent before saving the transfer state to disk.
| |||||||
Status on Percentage Increase | Maximum increase in percentage Maximumincreaseinpercentage completion before the FileTransmitter sends another status report.
| |||||||
Status on Packets Transmitted Count | Maximum increase in the Maximumincreaseinthe number of chunks sent before the FileTransmitter sends another status report.
| |||||||
Status on Delay Interval | Maximum delay, in milliseconds, before the FileTransmitter sends another status report.
| |||||||
Delay before retransmission | Delay, in milliseconds, after which the FileTransmitter calculates the file status from the receiver and sends retransmissions.

The configuration can be validated using the Validate button. Note that this button doesn't does not check the existence of the source directory. Successful The successful result of the Validate operation appears as below.

The table below provides descriptions for the Expert properties in CPS.
Property | Description |
Pre Processing XSL Configuration | Pre Processing XSL configuration can be used to transform request message before processing it. Click the ellipses button against the property to configure the properties. Refer to the Pre/Post Processing XSL Configuration section under the Common Configurations page for details regarding Pre Processing XSL configuration and Post Processing XSL configuration (below). |
Post Processing XSL Configuration | Post Processing XSL configuration can be used to transform the response message before sending it to the output port. |
Process Message Based on Property | The property helps components to skip certain messages from processing. Refer to the Process Message Based On a Property section under the Common Configurations page. |
Threadpool Configuration | This property is used when there is a need to process messages in parallel within the component, still maintaining the sequence from the external perspective. Refer to the Threadpool Configuration section under the Common Configurations page. |

Requesting a report on the current state of FileTransmitter. In this scenario, 1000 send requests are being sent as shown below and then a Status command is sent as shown in the Sample Input to know the files which need data to be resent, the files that are yet to be sent and the current state of transfer (paused/in progress).
