Hello guys,
I have read through a couple of pages on how to send an zip attachement through SMTP but none have the complete solution. sorry if you feel this is a repetition
Everything seems to be fine in Mainframe side and i didn't get any errors.
but when i tried opening the file in Windows using a ZIP utility it pops me the below error
[Cannot open the file: it doesn't appear to be a valid archive
if you downloaded this file , try downloading file again
]
I Zipped the file using PKZIP , the JCL is as below
| Code: |
[//STEP1 EXEC PGM=PKZIP,REGION=6M,TIME=90
//STEPLIB DD DSN=SYSU.PKZIP.LOADLIB,DISP=SHR
//SYSUDUMP DD SYSOUT=*
//SYSPRINT DD SYSOUT=*
//SYSIN DD *
-ARCHIVE_DSN(XXXXXXXXXXXX)
-ARCHUNIT(BIGPRD)
-ARCHSPACE(CYL)
-ARCHPRIMARY(10)
-ARCHSECONDARY(10)
-DATA_DELIMITER(LF)
-FILE_TERMINATOR(LF)
-TRANSLATE_TABLE_DATA(EBC#8859)
-ACTION(ADD)
YYYYYYYYYYYY
/* |
Note:
XXXXXXXXXXXX --> OUTPUT DATASET
YYYYYYYYYYYY --> INPUT DATASET
]
Emailing step is as below
| Code: |
//STEP1 EXEC PGM=LINKABND,PARM=(UCANDU,12)
//SYSPRINT DD SYSOUT=*
//SYSUT1 DD DSN=EMAIL.LIST(CNTCRD),DISP=SHR
// DD DSN=XXXXXXXXXXXX,
// DISP=SHR
//SYSUT2 DD DSN=TEMP.DATASET,
// DISP=(,CATLG,DELETE),
// UNIT=SCRTCH,
// SPACE=(CYL,(10,10),RLSE),AVGREC=K,
// DCB=(DCO01.DSCB,RECFM=U)
//SYSIN DD *
COPY,ALL
//*
//STEP2 EXEC PGM=IEBGENER
//SYSIN DD DUMMY
//SYSPRINT DD SYSOUT=*
//SYSUT1 DD DSN=TEMP.DATASET,DISP=SHR
//SYSUT2 DD SYSOUT=(A,SMTP)
//* |
]
Emailing details / Mime as below
[HELO xxxxx
MAIL FROM:<>
RCPT TO:<a@xxx.COM>
DATA
FROM: Report
TO: TEST MAIL
SUBJECT: Report
MIME-VERSION: 1.0
CONTENT-TYPE: APPLICATION/OCTET-STREAM; NAME="A.ZIP"
CONTENT-TRANSFER-ENCODING: BASE64 ]
Note: I tired using SAS to send the ZIped file and it was succesfull, i was able to open the Zip file in windows, which might mean by Zipping is fine.
Problem is I cant use SAS, Can anyone help me out of this.

Have you tested with using a different encoding?
Have you tested with a multi-part MIME message? |

Robert,
Since we i am transferring to windows EBCDIC needs to be converted into ACSII and BASE64 does that. Advise me if am wrong on this. |

1. You are ABSOLUTELY WRONG on this. A ZIP file is a BINARY file and if you translate it to ASCII then you no longer have a ZIP file -- you have garbage. This would explain your results -- a ZIP file that was translated is not an archive anymore.
2. BASE64 is an ASCII-encoding and it is NOT used for binary (that is, ZIP) file transfers. You should be using a binary encoding for your SMTP transfer. |

I have run into similar problem sometime back and was patiently waiting if someone would post a solution in this thread.
In our case we transferred the file to USS and zipped it there with TARZIP and then sent it through email. No exactly a solution, but a work around. |

| I think we need to change the length of the file, I think the error you get is because the length of all the SMTP files needs to be the same,else it gives an error.Did you try the same after modifying the length of the zipped file? |

Superman,
How do you propose to modify the length of a zipped file and still have the contents intact? (With super human strength? :-) )
As far as i know, i think ZIP files are of RECFM=U and LRECL=0
| Code: |
Organization . . . : PS
Record format . . . : U
Record length . . . : 0
Block size . . . . : 6144 |

Vasanth,
I had'nt thought of that.Does pose a problem.
So you mean to say there is no way I can transfer a PKZIP file via SMTP. |

Hello VasanthZ and Superman
I almost left this post as i really low on hope. hopefully this helps you
If zipping file to LRECL 80 will provide the solution here it is, you need to include two extra parameters
| Code: |
-ARCHUNIT(BIGPRD)
-ARCHSPACE(CYL)
-ARCHPRIMARY(10)
-ARCHSECONDARY(10)
-DATA_DELIMITER(LF)
-FILE_TERMINATOR(LF)
-ARCHIVE_LRECL=080
-ARCHIVE_RECFM=FB
-TRANSLATE_TABLE_DATA(EBC#8859)
-ACTION(ADD)
|
I was able to zip but failed with the SMTP |

Hello ALL,
Here is the piece of SAS code that works perfectly,I hope this turns out to be useful.
| Code: |
//SASMAIL EXEC SAS9,REGION=2M
//SYSIN DD *
DATA;
FILENAME MYFILE EMAIL
TO= "A@B.COM"
FROM= "A@B.COM"
SUBJECT= "SUBJECT OF UR MAIL"
ATTACH= ('ZIP FILE PS NAME'
NAME = 'A' EXT="ZIP"); ----> ZIP FILE NAME IN MAIL
DATA _NULL_;
FILE MYFILE;
PUT 'DESCRIPTION OF THE MAIL';
RUN;
QUIT;
/*
|
PS: There is Limit on SMTP, so if the sas execution went fine and you didnt receive the mail it means you have crossed the limit. |

Arjun,
I have been using Z/OS PKZIP lately and received the same error message as you did, but as Robert pointed out it was because I had NOT specified the transfer method of the zipped data set from mainframe to Windows as BINARY. One thing you may want to try is downloading a free copy of ZIPREADER (from PKZIP developer) to extract your data set once it is on your PC rather than WINZIP.
