[...] 8. Boykie and TomLiotta gave it their best shot trying to help figure out why AS/400 SFTP causes one position shift of data in send file. [...]

To show spacing, paste your lines. Then select the pasted lines and click the {code} box at the top of the entry area:

DATA FROM AS/400—————–||||||DATA WHILE LOADING INTO ORACLE
1222 XXX 333333 XYZ1 444444 ||||||1222 XXX||333333 XYZ1 444444
3323 YYY 213333 XYZ1 231233 ||||||3323 YYY|||213333 XYZ1 231233
2313 ZZZ 323233 XYZ1 231233 ||||||2313 ZZZ|||323233 XYZ1 231233

Please use WRKLNK (or the DSPF command) to view the portion of the file that causes the problem. Select a portion of the first record and the second and third records to show part of a good line and a couple bad lines. You only need to show a block of characters from before and after the problem area. The section might look like this:

,"233719","TESTLF    ","T
,"233719","TESTLF    ","T
,"233719","TESTLF    ","T
,"233719","upddta2   ","T

Then, while still viewing the file, press so you can copy/paste a {code} block like:

2C223233 33373139 222C2254 4553544C 46202020   ,"233719","TESTLF   
2C223233 33373139 222C2254 4553544C 46202020   ,"233719","TESTLF   
2C223233 33373139 222C2254 4553544C 46202020   ,"233719","TESTLF   
2C223233 33373139 222C2275 70646474 61322020   ,"233719","upddta2

Finally, press to get back to character mode and press to show the CCSID of the file. Paste the CCSID value back here. Something odd is going on. The data needs to be examined to be sure of some possibilities. Tom

Hi Tom, Presently,We are doing an Enhancement, where we are sending files from AS/400 to Oracle through Unix Interface(SFTP). DATA FROM AS/400-----------------||||||DATA WHILE LOADING INTO ORACLE 1222 XXX 333333 XYZ1 444444 ||||||1222 XXX||333333 XYZ1 444444 3323 YYY 213333 XYZ1 231233 ||||||3323 YYY|||213333 XYZ1 231233 2313 ZZZ 323233 XYZ1 231233 ||||||2313 ZZZ|||323233 XYZ1 231233 Here, whats happening is after file received into oracle and during loading, first line loading in proper way, but when coming from second line onwards, data shifting by one position starts from YYY. This is because length of second field is 4, due to we filled with only 3, and left WITH one blank position(XXX/YYY/ZZZ), this blank causes shift of rest of the record by one position. (213333 XYZ1 231233) I would like to check with you, is unix causes such a cause while sending from system1 to System2 Thank you! Venkat

Hi Tom,
Presently,We are doing an Enhancement, where we are sending files from AS/400 to Oracle through Unix Interface(SFTP).

DATA FROM AS/400 DATA WHILE LOADING INTO ORACLE
1222 XXX 333333 XYZ1 444444 1222 XXX 333333 XYZ1 444444
3323 YYY 213333 XYZ1 231233 3323 YYY 213333 XYZ1 231233
2313 ZZZ 323233 XYZ1 231233 2313 ZZZ 323233 XYZ1 231233

Here, whats happening is after file received into oracle and during loading, first line loading in proper way, but when coming from second line onwards, data shifting by one position starts from YYY. This is because length of second field is 4, due to we filled with only 3, and left WITH one blank position(XXX/YYY/ZZZ), this blank causes shift of rest of the record by one position.

I am copying data from flat file to path…

How are you copying it? Show us the command or program code that did the copying.

…and sending on SFTP.

Sending to what? What kind of system? Unix? Windows? AS/400? Mainframe?

I would first look at what you chose for a record delimiter. The first thing that comes to mind is that you used a Carriage-return/line-feed combination, but the receiving system only reacts to newlines (line-feeds).

Maybe other possibilities will come to mind if we know what is being done.
