Hi All, am getting a time out while trying to FTP a .txt file to a dataset.
Pls let me know what information I need to furnish.

Outside of any obvious issues, presuming that the process is normally functional, I'd be asking my network engineers to run a network sniffer trace between the servers.

OK, Just FYI Its a UNIX server.

Has the FTP ever run? If so, ask your site support group what got changed. If not, you need to talk to your site support group to ensure the routers involved are set up for the FTP -- sometimes they are, sometimes they are not. A time out could also occur if the Unix server's FTP listener died for some reason, or never got started.

Thanks Robert and Kevin. I'll check these things. Apart from that is there a chance that the JCL is responsible for Time out.

In FTP a time out occurs when one side does not respond within the specified number of seconds (a configuration option). Unless your JCL points to the wrong IP address, there is no way JCL per se will cause a time out -- only the FTP client and FTP server could generate a time out. And even if the JCL points to the wrong IP address, it would still be the FTP server on the other end of the connection that would time out (especially if there were no FTP server on the other end of the connection, since the time out would occur while attempting to connect to the server).

Sometimes additional data is generated in the FTP output that can help resolve time outs -- if you can, post the OUTPUT of the FTP (redact the identification data of course).
