Ciao a tutti,
I tested the gzip utility for our GC DSTs runs.
In a first moment I gziped a RAW GC file (run11111) and I tried to
copy it on a 'scratch' tape without success. I received a QIO system
error (see DISK$SCRAUSA9:[MACRODATA.RAW.TEST]test.log for detailes).
I tried again changing the SET FILE/ATTRIB=(RFM:FIX,LRL:21600) for
the GC file and gzipping it again w/o success (same error).
This should be due to the Record format of a gziped file that is Stream_LF.
Then I used the VMSTOTAR utility and I had no problems in copying the
file so obtained (DISK$SCRAUSA9:[MACRODATA.RAW.TEST]GC011111_TAR.DST;1) on
the tape and in recovering it (of course I had to mount the drive
using /REC=512).
The output file (from the tape) is
DISK$SCRAUSA9:[MACRODATA.RAW.TEST]GC011111_TAR_TAPE.DST and it is binary
identical to the source one.
Then I tried to unzip the 2 *TAR* files w/o success ("unknown suffix").
I think I should change again the Record format in Stream_LF....
Could someone of you tell me how to do it?
