Input File Handling

Input Type

The agent can act on two input types. Depending on which one the agent is configured to work with, the behavior differs.

The default input type is bytearray, that is the agent expects bytearrays. If nothing else is stated the documentation refers to input of bytearray.

If the input type is MultiForwardingUDR, the behavior is different. For further information about the agent's behavior in MultiForwardingUDR input, see SCP Forwarding Agent MultiForwardingUDR Input.

File Information

Directory

Enter the absolute pathname of the target directory on the remote host, where the forwarded files will be placed. The pathname may also be given relative to the home directory of the user's account.

The files will be temporarily stored in the automatically created subdirectory DR_TMP_DIR in the target directory. When an End Batch message is received, the files are moved from the subdirectory to the target directory.

Create Directory

When enabled, this will create the directory, or the directory structure, of the path that you specify in Directory.

Compression

Select the compression type of the destination files. Determines whether the agent will compress the output files as it writes them.

• No Compression - the agent will not compress the files.

• Gzip - the agent will compress the files using gzip.

Target File Handling

Produce Empty Files

If enabled, the agent will create empty output files for empty batches rather than omitting those batches.

Handling of Already Existing Files

Select the behavior of the agent when the file already exists, the alternatives are:

• Overwrite - The old file will be overwritten and a warning will be logged in the System Log.

• Add Suffix - If the file already exists the suffix ".1" will be added. If this file also exists the suffix ".2" will be tried instead and so on.

• Abort - This is the default selection and is the option used for upgraded configurations, that is workflows from an upgraded system.

Temporary File Handling

Use Temporary Directory

If this option is selected, the agent will move the file to a temporary directory before moving it to the target directory. After the whole file has been transferred to the target directory, and the endBatch message has been received, and the temporary file is removed from the temporary directory.

Use Temporary File

If there is no write access to the target directory and, hence, a temporary directory cannot be created, the agent can move the file to a temporary file that is stored directly in the target directory. After the whole file has been transferred, and the endBatch message has been received, the temporary file will be renamed.

The temporary filename is unique for every execution of the workflow. It consists of a workflow and agent ID, and a file number.

Abort Handling

Select how to handle the file in case of cancelBatch or rollback, either Delete Temporary File or Leave Temporary File.

Advanced Settings

Port

Enter the port number the SCP service will use on the remote host.

Timeout (s)

Enter the maximum time, in seconds, to wait for a response from the server. 0 (zero) means to wait forever.

Accept New Host Keys

If selected, the agent overwrites the existing host key when the host is represented with a new key. The default behavior is to abort when the key mismatches.

Enable Key Re-Exchange

Used to enable and disable automatic re-exchange of session keys during ongoing connections. This can be useful if you have long lived sessions since you may experience connection problems for some servers if one of the sides initiates a key re-exchange during the session.

Buffered Mode

Select this check box if you want to enable buffered mode on the SCP client.

Additional Hosts

Additional Hosts

List of additional host names or IP addresses that may be used to establish a connection. These hosts are tried, in sequence from top to bottom, if the agents fail to connect to the remote host set in the Connection tab.

Use the Add, Edit, Remove, Up, and Down buttons to configure the host list.

After Treatment

Execute

Select between the two options:

• Before Move: Execute the following command and its arguments prior to transfer.

• After Move: Execute the following command and its arguments on the local copy of the transferred UDR, after transfer.

Command

Enter a command or a script

Arguments

This field is optional. Each entered parameter value has to be separated from the preceding value with a space.

The temporary filename is inserted as the second last parameter, and the final filename is inserted as the last parameter, automatically. This means that if, for instance, no parameter is given in the field, the arguments will be as follows:

$1=<temporary_filename>   $2=<final_filename>

If three parameters are given in the Arguments field, the arguments are set as:

$1=<parameter_value_#1> $2=<parameter_value_#2> $3=<parameter_value_#3> $4=<temporary_filename> $5=<final_filename>

Enable Backlog

When selected, this will enable the backlog functionality. When not selected the agent's behavior is similar to the standard SFTP forwarding agent.

Directory

Base directory in which the agent will create sub-directories to handle backlogged files. Absolute or relative path names can be used.

Type

Files is the maximum number of files allowed in the backlog folder. Bytes is the total sum (size) of the files that reside in the backlog folder. If a limit is exceeded the workflow will abort.

Size

Enter the maximum number of files or bytes that the backlog folder can contain.

Processing Order

Determine the order by which the backlogged data will be processed once the connection is reestablished, and select between First In First Out (FIFO) or Last In First Out (LIFO).

Duplicate File Handling

Specifies the behavior if a file with the same file name as the one being transferred is detected. The options are Abort or Overwrite and the action is taken both when a file is transferred to the target directory or to the backlog.
