FTP file from mainframe to multiple servers at same time

Hi,

Currently i am FTPing a file from mainframe to 3 different unix servers in JCL through 3 different steps. Each step will call a control card which had details about the destination server.

I want to eliminate these 3 steps in JCL. I need to FTP the file to 3 different servers at the same time in a single step. I wrote a REXX program which will dynamically create FTP control card which has details about 3 servers
I am invoking this FTP control card. When we run the JCL it successfully FTPs to the first server and then it quits automatically. It doesn’t FTP to the next server. It says invalid command. I am not sure if we can transfer a file to more than one server through the same control card.

Please let me know if it is possible and some idea on how should i proceed.

Thanks.

Is it possible to FTP to mulitple destinations?
Do you have a link to an FTP manual?

Sorry i couldnt get your question.
You can FTP a file to multiple different servers through different steps in JCL.

Do you have a link to an FTP manual? --- couldnt understand this

Is it even possible to FTP to multiple destinations (as with email) in a single step/FTP execution?
Do you have the FTP manual available to you to look this up?

I think XCOM will do the job.

Yes, it is. Once FTP has started it can open and close sessions as many times as it needs to.

Could you please provide me some idea on how can i do this.

I had created a control card as below:

servername1
userid1
password1
send file using put command
quit
servername2
userid2
password2
send file using put command
quit

called this control card in the FTP step thru JCL.

It successfully FTPs to servername1. After that it doesnt recognize any command and says invalid command. Hence not able to ftp to servername2.

Please advise.

You need to get rid of the quit statements (except for the last one).

I have tried that option. But it doesnt work.
coded as below:

servername1
userid1
password1
send file using put command

servername2
userid2
password2
send file using put command
quit

It FTPed to servername1 and then it threw error as invalid command for servername2, userid2,password2. Again it FTPed file to same servername1.

Maybe put a "disconnect" or "close" between the following statements :

send file using put command

servername2

You DO need to close the sessions between servers:

CLose subcommand--Disconnect from a remote host.

I tried this option and it worked. Thanks all for your timely help.

I have a doubt here. If the FTP of the first server failes will it still continue to FTP to the next server?
Is there a way to find out if the file was FTPed successfully in control card.

you can verify spool to see if there is any FTP failed statements.... Or you can issue a list command on to the servers once all FTPs are done

I tried failing the FTP of first server to see if the second server FTP runs succesfully. It didnt invoke the second server's FTP and it returned error code 1808.
My requirement is to successfully run FTP of the second server even if the first server FTP fails. Kindly provide me some pointers on how i can do this.

Run multiple steps or multiple jobs. If the first FTP does not complete successfully, then z/OS considers the step to have failed and will not execute any other FTP commands. So you cannot do what you want in a single step of a job.

Once again XCOM will do the job.

Oh, I almost forgot. You have to have it installed of course.

The funny thing is, I had been thinking about posting a comment to this that I didn't think it would be a good idea to do this because of exactly this issue.
