FTP Adapter

The FTP adapter is used to work with an FTP server in your local environment from RunMyProcess DigitalSuite. By means of the FTP server, you can get, add, and delete files, list and rename files and folders (directories), and create and remove folders in your local environment.

Prerequisites

The following prerequisites must be fulfilled to install and run the FTP adapter:

You must install the adapter on a local system in your environment. This can either be the system where you have installed the DigitalSuite EnterpriseConnect Agent, or a different one which is able to connect to the Agent's host.
You can install the adapter several times in your environment, for example, to work with different FTP servers. The identifier of the adapter (protocol setting in the handler.config configuration file) must be unique for each of the installations.
The local FTP server (e.g. standard FTP server of Microsoft Windows, VSFTPD on Linux) you want to use must be running and configured to allow access by the adapter.
The files and folders to be handled from RunMyProcess DigitalSuite must be accessible from the FTP server.

Installing the Adapter

To install the adapter:

Download the following ZIP file: unified-adapter-[version].zip

[version] is the current version number

The ZIP file contains executables, licences, configuration files, and reference files for several adapters.
Extract the ZIP file to a local folder. The following path is recommended:

[parent-folder]\adapters\ftp

[parent-folder] is a folder of your choice. If the EnterpriseConnect Agent is installed on the same machine, use its installation folder as the [parent-folder], for example, C:\ProgramFiles (x86)\dsec-agent.
Copy the configuration files for the FTP adapter, FTP.config and handler.config, from the configFiles\ftp.reference subfolder to the configFiles folder, for example:
```
copy configFiles\ftp.reference\*.config configFiles
```
Overwrite existing files in the configFiles folder.
If desired, delete obsolete files. Only the following folders and files are required in the ftp folder to use the adapter:
```
ftp
├── configFiles
│   ├── handler.config
│   └── FTP.config
├── lib
│   └── unified-adapter-[version].jar
└── log.properties
```
In addition, we recommend you keep the following:
- runAdapter.bat batch file for starting the adapter on Microsoft Windows
- ftp.reference subfolder in the configFiles folder for reference purposes

Configuring the Adapter

Configuration settings for the FTP adapter are required in the following configuration files:

handler.config
FTP.config

Edit the files with a plain text editor.

handler.config

The handler.config file contains general configuration settings for connecting the adapter to the EnterpriseConnect Agent:

#Generic Protocol Configuration
protocol = FTP
protocolClass = org.runmyprocess.sec2.FTP
agentHost = 127.0.0.1:8080
pingFrequency = 1000
adapterConnectionInterval = 1000
offlineLogsMaxSize = 100
maxNumberOfLogsInBatch = 100
clusterEnabled = false
clusterAgentsHttpAddressList = localhost:8071,localhost:8072,localhost:8073

The settings have the following meaning:

protocol: The identifier of the adapter. If you install the adapter several times in your environment, the identifier must be unique for each of the installations, for example, FTP1 and FTP2.
protocolClass: The adapter's Java class.
agentHost: The IP address and port of the EnterpriseConnect Agent.
pingFrequency: The frequency in milliseconds in which the adapter pings the EnterpriseConnect Agent.
adapterConnectionInterval: The frequency in milliseconds in which the adapter tries to connect to the EnterpriseConnect Agent.
offlineLogsMaxSize: The maximum number of log entries that the adapter collects locally and sends to the EnterpriseConnect Agent when it re-connects to it after it was disconnected.
maxNumberOfLogsInBatch: The maximum number of log entries the adapter sends to the EnterpriseConnect Agent at a time. A value of 0 means that the number of log entries sent at a time is unlimited.
clusterEnabled: true if the EnterpriseConnect Agent is configured and running as a cluster, false otherwise.
clusterAgentsHttpAddressList: The IP addresses and ports of the EnterpriseConnect Agent cluster, if clusterEnabled is set to true.

FTP.config

The FTP.config file contains specific settings for the adapter:

#FTP Configuration
host=127.0.0.1
port=21

The settings have the following meaning:

host: The host name or IP address of the FTP server to be used. Specify just the name or IP address without ftp://.
port: The port of the FTP server.

Starting the Adapter

The adapter needs to be running to be able to access files and folders by FTP.

Before you start the adapter, make sure that the DigitalSuite EnterpriseConnect Agent is running.

To start the adapter:

Change to the ftp installation folder.
Execute the following command, depending on the operating system:
- On Microsoft Windows: Execute the runAdapter.bat batch file.
- On Linux: Execute the following command directly, or create and execute a corresponding shell script to do so:
```
java -XX:+UseG1GC -XX:+ExitOnOutOfMemoryError -Djava.util.logging.config.file=./log.properties -cp lib/*: org.runmyprocess.sec2.AdapterHandler
```

Using the Adapter

If everything is configured and running correctly, you can place requests to the local FTP server from RunMyProcess DigitalSuite through the EnterpriseConnect Agent and the FTP adapter. Follow the examples below to get, add, and delete files, list and rename files and folders (directories), and create and remove folders in your local environment.

Request: POST on http://[agent-host]:[port]/, where [agent-host] and [port] are the IP address and port of the EnterpriseConnect Agent.

Content Type: application/json

Accept: application/json

Content (examples):

The message body is a JSON (JavaScript Object Notation) object whose structure depends on the operation to be executed. Each operation requires a nested JSON object with the outer object specifying the protocol, and the inner object defining the operation-specific parameters.

Some examples are described below. You can also find a sample request in the ftp.reference\InputJSONExample.txt file in the ftp installation folder.
