FTP can GET or PUT directly to HFS file systems as long as you have the permissions to get to the directory and file. So run a mainframe FTP job to move the file to the FTP server.

I have tried in the below manner

Code:

sds.server.com
userid
pass
bin
cd 'hfs:/SYE1/tmp/'
put 'claims.txt'  data\claims.txt
quit
 


I get the error message as "Invalid local file identifier". The FTP program is unable to locate the HFS path, where as a SAS program is able to identify. I got this path when I set the FILESYSTEM options as 'HFS'.

Can you give me any ex. for reference...??

Try this instead:
Code:
sds.server.com
userid
pass
bin
cd /SYE1/tmp/
put 'claims.txt'  data\claims.txt
quit
As I said, FTP understands HFS file systems -- all you have to do is enter "cd /directory/directory/file" and you'll be there.

Sigh ... any chance /SYE1/tmp is on your LOCAL mainframe and you're connecting to another box for the FTP? If so, change my previously provided cd /SYE1/tmp/ to lcd /SYE1/tmp/

And if that doesn't work, post some actual FTP messages with the header numbers so we can see what's going on.

Thanks for your inputs....The below are the updates from my side...Now the FTP is able to identify the HFS path, but it says "There is no file with the specified name"

Code:

  libname claimst 'USERID.CLAIMS.FILE'; 
  libname hfs1 '/SYE1/tmp/';                                       
  data hfs1.AUS_CLAIMS(outrep=windows_32);               
    set claimst.AUS_CLAIMS;                           
  run;                                                             
                                                                   
  FILENAME INPUT  "USERID.FTP.TEMPIN";                           
  FILENAME OUTPUT "USERID.FTP.TEMPOUT";                           
  data _null_;                                                     
       file input;                                                 
       infile cards;                                               
       input;                                                     
       put _infile_;                                               
  cards;                                                           
CSC.FTP.COM

lcd '/SYE1/tmp/'                                                   
put 'AUS_CLAIMS.sas7bdat' +

As the SAS log says... HFS1.AUS_CLAIMS.DATA, I have modified the FTP card as
Code:

put 'AUS_CLAIMS.DATA' +                           
     Data19\AUS_CLAIMS.DATA     

and result is
Code:
     
put fails: /SYE1/tmp/AUS_CLAIMS.DATA does not exist


any clue...??

Try
Code:
put 'AUS_CLAIMS +                           
     Data19\AUS_CLAIMS.DATA 
The SAS code indicates the library name was AUS_CLAIMS with no extension. You might want to go into OEIS or OMVS and do an ls on /SYE1/tmp/ to see what is in the directory.

One way would be
Code:
//TMP      EXEC  PGM=IKJEFT01,REGION=0M,
//         DYNAMNBR=200
//SYSPROC  DD  DSN=SYS1.SBPXEXEC,DISP=SHR
//SYSTSPRT DD  SYSOUT=*
//STDOUT   DD  SYSOUT=*
//SYSTSIN  DD  *
  oshell ls -al /SYE1/tmp/
/*
//
although you may have to ask your site support group about the location of the SYS1.SBPXEXEC file; this is not required to be SYS1.SBPXEXEC.

The ls command in FTP is going to list the directory for the other side of the connection -- not your local directory.

Another thing you could try would be to FTP from your desktop to your mainframe, signing in with your user id and password, then issuing the cd /SYE1/tmp/ and ls -al commands.

But, the command " lcd /SYE1/tmp/ " says that -
"HFS directory /SYE1/tmp/ is the current working directory".

Then the command " ls " should also search in the HFS directory only rt..??

When you're doing FTP, be aware of the difference between lcd and cd -- lcd changes the directory on your local machine (i.e., the client) whereas cd changes the directory on the remote machine (i.e., the server). The ls (or its equivalent dir) command does not work on the local machine -- only the remote machine.

Hello Robert,

Can you let me know like will there be any space constraint in the HFS ...?? I mean is that preallocated with a predifined size...??

Yeah, Unix is case sensitive -- so AUS_CLAIMS and aus_claims are different files. Glad to hear you got it solved.

Be aware that Unix System Services support zFS and HFS file systems -- HFS is not being upgraded in the future as IBM wants everybody to move to zFS. HFS files are allocated via JCL and if defined with a secondary can grow just like any sequential file. zFS files are VSAM linear data sets, are defined through IDCAMS, and are preformatted before use. Depending upon your operating system release, it may or may not be possible to dynamically extend their size -- I believe that feature came in version 1.9 of z/OS (but don't hold me to that -- I haven't verified it).

How to tell the difference? If you have access to OEIS on your TSO menu, you can use the File_systems tab at the top of the screen to look at the mounted file systems; if you have access the Attributes include whether the mounted file system is HFS or zFS. Otherwise you may have to talk to your systems support group to find out for sure. For example:
Code:
