I am receiving error message as:

tar -zxvf OVM_EL5U3_X86_EBIZ12.1.1_DB_VIS_PVM.tgz.1

gzip: stdin: not in gzip format
tar: Child returned status 1
tar: Error is not recoverable: exiting now

file name is ending with. Tgz. 1.

When file name is. Tgz. 0 it will unzip by tar -zxvf command.

Why not rename it? – hexafraction Dec 19 '12 at 12:12
Is this file splitted? – Zignd Dec 19 '12 at 12:12
I had rather run file OVM_EL5U3_X86_EBIZ12.1.1_DB_VIS_PVM.tgz.1 to see what exactly it is. – Nehal J. Wani May 12 '14 at 18:10

This is what i found after a quick google search, a PDF explaining how to correctly extract the contents of the file.

Looks like there are several files:


You need to copy all those files to a specific directory, /OVS/seed_pool/ . Then run the following commands:

# cd /OVS/seed_pool
# cat OVM_EL5U3_X86_64_EBIZ12.1.1_DB_VIS_PVM.tgz.0 \
OVM_EL5U3_X86_64_EBIZ12.1.1_DB_VIS_PVM.tgz.1 \
OVM_EL5U3_X86_64_EBIZ12.1.1_DB_VIS_PVM.tgz.2 \
OVM_EL5U3_X86_64_EBIZ12.1.1_DB_VIS_PVM.tgz.3 \
OVM_EL5U3_X86_64_EBIZ12.1.1_DB_VIS_PVM.tgz.4 \
OVM_EL5U3_X86_64_EBIZ12.1.1_DB_VIS_PVM.tgz.5 \
OVM_EL5U3_X86_64_EBIZ12.1.1_DB_VIS_PVM.tgz.6 \
OVM_EL5U3_X86_64_EBIZ12.1.1_DB_VIS_PVM.tgz.7 | tar -xz

Note those are only 2 commands, denoted with the starting #.

Those commands shall create the following directory structure, with these files inside:

|- System.img (OS image file)
|- ebs1211db.img.img (Oracle E-Biz 12.1.1 DB Tier image file)
|- vm.cfg (VM configuration file)
|- README.txt

For more help, please look into the PDF mentioned above.

The tar.gz/tgz file you are having is split into multiple files. (tgz.0, tgz.1,tgz.2 etc..)

So that's the reason when you try to extract using the command

tar -zxvf OVM_EL5U3_X86_EBIZ12.1.1_DB_VIS_PVM.tgz.0

it works properly. But the contents wont be fully available.

Use the cat command to combine all the OVM_EL5U3_X86_64_EBIZ12.1.1_DB_VIS_PVM.tgz.* parts into one tar.gz file

then use the command

tar -zxvf OVM_EL5U3_X86_EBIZ12.1.1_DB_VIS_PVM.tgz

These files include multiple files and sub-directories into a single file using tar command. To save the bandwidth tar files are compressed using gzip program.

tar zxvf backups.tgz

tar command options

-z : Uncompress the resulting archive with gzip command.
-x : Extract to disk from the archive.
-v : Produce verbose output i.e. show progress and file names while extracting files.
-f backup.tgz : Read the archive from the specified file called backup.tgz.
-C /tmp/data : Unpack/extract files in /tmp/data instead of the default current directory.
