These are the UDRs related to the TCP IP processing agent.

RemoteHostConfig

The RemoteHostConfig UDR contains the connection details for the remote host. This UDR is included in all the other UDR types.

The following fields are included in the RemoteHostConfig:

Field	Description

Field	Description
`host (string)`	This field contains the hostname or IP address to the remote host.
`port (int)`	This field contains the port to the remote host.

ConnectionRequestUDR

When the agent receives this UDR, it tries to establish a new connection, or close a connection to a a remote host. The agent then returns the ConnectionStateUDR containing information about the current state of the connection.

The following fields are included in the ConnectionRequestUDR:

Field	Description

Field	Description
`closeConnection (boolean)`	This field determines whether the request is for opening or closing a connection. If a new connection is to be made, this field is set to `false`, and if a connection is to be closed, this field is set to `true`.
`remoteHost (RemoteHostConfig (TPCIP))`	This is the RemoteHostConfig UDR containing the connection details.

ConnectionStateUDR

The agent returns the ConnectionStateUDR when a ConnectionRequestUDR has been sent, as well as if a connection goes down for some reason.

The following fields are included in the ConnectionReqeustUDR:

Field	Description

Field	Description
`connectionOpen (boolean)`	If you have a valid connection (see the `validAddress` field below), this field indicates whether the connection is open or not, `true` for open and `false` for closed.
`remoteHost (RemoteHostConfig (TPCIP))`	This is the `RemoteHostConfig` UDR containing the connection details.
`validAddress (boolean)`	This field indicates if the connection details in the `RemoteHostConfig` UDR are valid or not, `true` for valid and `false` for invalid.

RequestUDR

When the agent receives a RequestUDR it tries to send the included bytearray to the remote host.

The following fields are included in the RequestUDR:

Field	Description

Field	Description
`data (bytearray)`	This field contains the actual data to be sent.
`remoteHost (RemoteHostConfig (TPCIP))`	This is the `RemoteHostConfig` UDR containing the connection details.

ResponseUDR

If the TCP/IP processing agent has been configured to handle responses, it returns ResponseUDRs to the workflow.

The following fields are included in the ResponseUDR:

Field	Description

Field	Description
`data (bytearray)`	This field contains the response.
`remoteHost (RemoteHostConfig (TPCIP))`	This is the `RemoteHostConfig` UDR containing the connection details.

Note!

An internal buffer in the TCP/IP processing agent limits the maximum data size of a response. If the size exceeds 1024 bytes, the response may be split into multiple UDRs. For each response that exceeds the limit, the agent automatically increases the buffer size in a stepwise manner.

ErrorUDR

The agent returns the ErrorUDR if a RequestUDR fails.

The following fields are included in the ErrorUDR:

Field	Description

Field	Description
`data (bytearray)`	This is original data from the `RequestUDR`. This can be used for storing the data.
`ErrorReason (string)`	This field contains the reason for the failure.
`ErrorStackTrace (string)`	This field contains the stack trace from the failure. Note! This field should only be read if absolutely necessary, since it requires a large amount of CPU.
`remoteHost (RemoteHostConfig (TPCIP))`	This is the `RemoteHostConfig` UDR containing the connection details.
