If you send a ping to a server, a response will only indicate the the server is up. You can issue ping as a TSO command in a batch TSO step, parse/read the resulting output, and go from there.
If you want to confirm that FTP is up and responding, you're going to have to open an FTP session, log on, receive an FTP command prompt, etc. |

And what do you do if FTP is not available on the server? The batch job can't just sit there and wait for FTP to come up.
This is a management issue disguised as a technical issue. Management needs to determine when the FTP server will be up and available so the batch job can be scheduled during that window. Any technical solutions to the management problem are, at best, somewhat limited since they can't address the root problem of the FTP server being down when it is needed. |

As Kevin warned, PING does not tell you that FTP is available on the server. |

Hello,
Suggest you not waste time checking server availability - just sent the file and if the send fails (for any reason) the job should present the error in whatever manner is standard for reporting errors on your system.
Also suggest that something be scheduled on the server to "pull" the data rather than have the mainframe "push" the data. The mainframe is more likely to be up and available.
As was mentioned - this is really a management issue looking for a technical solution. . . |
