Hi,

I need to compress the file which is stored in tape and write the compressed file into disk using PKZIP utility.

I ran this step, but it is working for disk files but tape.
Code:

//STEP41   EXEC PGM=PKZIP,REGION=0M
//SYSPRINT DD  SYSOUT=*
//DATAFILE DD  DSN=ARET.XX.TAPE,
//             DISP=SHR
//ZIPFILE  DD  DSN=ARET.YY.ZIP,
//             DISP=(NEW,CATLG),
//             UNIT=SYSDA,
//             DCB=(RECFM=U,DSORG=PS,BLKSIZE=(32465))
//SYSIN    DD  *
-ECHO
-ARCHIVE_OUTFILE(ZIPFILE)
-INFILE(DATAFILE)
-COMPRESSION_LEVEL(SUPERFAST)
-GZIP
-DATA_TYPE(BINARY)
-SAVE_LRECL(Y)
/*

Please help me.

Thanks,
Sattia

Standard-label (SL) or Non-labeled (NL)?

I tried this code
Code:

//STEP41   EXEC PGM=PKZIP,REGION=0M
//SYSPRINT DD  SYSOUT=*
//TAPEIN   DD  DSN=A021721.SPH30490.EOWL2.TNDREXTR.TAPE,
//             UNIT=TAPE,
//             LABEL=(1,NL),
//             DCB=(RECFM=FB,LRECL=755,BLKSIZE=(32465)),
//             DISP=OLD
//SYSIN    DD  *
-ARCHIVE(A021721.OUT)
-INFILE(TAPEIN)

But this is also not working.

sattia,

Non labeled tapes do not contain DCB(lrecl,recfm,blksize) information that PKZIP is looking for compressing. So you need to add the DCB info on the DD statement.
Code:

//DATAFILE DD  DSN=ARET.XX.TAPE,
//             DISP=SHR,
//             UNIT=TAPE,LABEL=(1,NL),
//             DCB=(LRECL=nnn,RECFM=yy,BLKSIZE=aaaaa)             


Hope this helps...

Cheers

Kolusu

In your JCL you have assigned the tape file to Datafile DD. Correct that.
