SFTP to another server using infosphere streams 3.2

Question

I am trying to write a small SPL program in Streams 3.2

In that I need to generate files using filesink and the same file has to be transfered to another server using FTPCommand.

I have copied the com.ibm.streamsx.inet package in path $STREAM_INSTALL/toolkit, but I get an error message;

The same has done for Streams 4.2 also. still I am getting same error even this package is available in streams 4.2 version.

Can any one please help me?

Answer 1

You need to add the toolkit location of the com.ibm.streamsx.inet toolkit to your sc command.

sc -M TcpExample -t $HOME/toolkits/streamsx.inet.toolkits-2.7.4-20160502-0727/com.ibm.streamsx.inet/

Remark: Code sample above works only if you downloaded and extracted the inet toolkit from gitHub (https://github.com/IBMStreams/streamsx.inet/releases/download/v2.7.4/streamsx.inet.toolkits-2.7.4-20160502-0727.tgz) to $HOME/toolkits, otherwise you need to change the path given with -t option.

If you like to transfer a file from local to remote host, probably the FTPPutFile operator is the better choice. The streamsx.inet toolkit from public github requires streams minimum version 4.0.1. So the streams version 4.2 is fine.

Some time ago I provided a custom version of the toolkit which contains only the FTP operators but can be used with a streams release 3x (platform RHEL6 X86-64) here: https://github.com/joergboe/streamsx.inet/releases/tag/untagged-026faf73c5c2628bd514
