4.6.4.1.1 RRP I/O Parameter: Input
It is possible to select the source of the input data. The input may either come from standard input
or from a file.
If standard input is selected, the standard output of another tool must be piped to this tool (refer to
section 4.6.3.1.2 of the ’Raw Data Record’ tool), else the option ’standard input’ is not applicable.
Example:
The command "recordraw –e localhost –p 5545 | replayrawsendraw –g" starts the ’Raw Data Record’
tool listening to port 5545 of the local host. The received data are not logged to standard output, but
piped to the ’Replay Raw Data Send Raw Data’ tool, which starts up in graphical mode. The ’Replay
Raw Data Send Raw Data’ tool replays the data received via standard input, if the corresponding radio
button is selected and replay is started.
If selecting the radio button ’file’, it is possible to choose an input file by pressing the button ’Choose’,
which opens a file selection dialog as shown in section 4.6.3.1.4 .
NOTE: It is not possible to enter the input file name directly into the textfield. The destination host
can be changed only by a supervisor user in a non−intuitive fashion in order to avoid acci-
dental replay of data into a live operational system.
If the data read from input are not of raw data format, then an error message is written to standard
output. The error message says that there are missing columns in the read records.
4.6.4.1.2 RRP I/O Parameter: Interface
A mandatory parameter is the address of the interface, where data shall be sent to. The address con-
sists of the hostname and the port of the socket, to which the data have to be output. Only the IP port
can be changed within the application. The hostname is a parameter only accessible within the config-
uration file (access restrictions apply).
4.6.4.1.3 RRP I/O Parameter: Logging
Logging to ’Screen Output’ can be done in the same format being used for file logging (one line per
record) or in a verbose mode. The layouts of the formats are introduced in section 4.6.3.1.3 .
The size of the ’Screen Output’ buffer can be limited in the corresponding text field. The textfield con-
tains the maximum number of lines, the ’Screen Output’ buffer shall contain.
