Hi, Hoping for help with a gzip issue on Solaris 9. We have used gzip to decompress files sourced from a Z/os mainframe which have been compressed with PKZIP for many years. On Z/os there is a PKZIP option to produce a gzip compatible file. E.g.
//STEPZIP EXEC PGM=PKZIP,REGION=2048K //STEPLIB DD DISP=SHR,DSN=SYS1.ZIP.LOAD //SYSPRINT DD SYSOUT=* //SYSIN DD * -ARCHIVE(DPFCBTE.C824797.TESTZIP.ARC.DS9) -ARCHIVE_SPACE_MULTIVOL=Y -TEMP_SPACE_MULTIVOL=Y -ARCHUNIT(SYSDA,59) -ARCHSPACE(TRK) -ARCHPRIMARY(10) -ARCHSECONDARY(10) -ZDW -BINARY -GZIP DPFCBTE.C824797.TESTZIP.DS9 /* Z/os job control language may not make much sense to non mainframers but I include it to be complete. The SYSIN card is the command input fpr pkzip. Recently we have started to receive bigger files and are getting an error message gunzip: FLEXCBA0001241111251111_RT.gz: invalid compressed data--length error However unzip can decompress the file. ssdb0046t:c836088>unzip FLEXCBA0001241111251111_RT.ZIP Archive: FLEXCBA0001241111251111_RT.ZIP SecureZIP for z/OS by PKWARE inflating: QPFCB/C1111/C25T0002/BITS/UNBLK We can compress the uncompressed file produced by unzip. ssdb0046t:c836088>gzip UNBLK ssdb0046t:c836088> We can gunzip the compressed file also ssdb0046t:c836088>gunzip UNBLK.gz ssdb0046t:c836088>ls -ltrh total 10899144 -rw-r----- 1 c836088 staff 5.2G Dec 8 23:47 UNBLK ssdb0046t:c836088> So any problems do not appear to be due to the data itself. Are there any known gzip bugs that might cause this error??
