AIX

Hi,

I have a question.
Im trying to tar a files that the size is bigger that 2 gig.
When i tried to tar it, i got an error says "eached end-of-file before expected"

How can i solve this?

Thanks and Regards

You are reaching the maximum file size allowed. Change the user settings for soft maximum file size and hard maximum file size to a bigger value or to -1 to set the limit to infinity.

I have faced this problem once in AIX for Oracle user.
this options should be set while creating user itslef.
I think if u change now,it will not work.
U have to execute some scripts after changing to -1 .

Yeah.
The Dba did some modification in the machine, so that's the reason why i cannot tar any files that size more than 2 gig.

But, let say the file is 10 gig, is there any automated way i could do...do cut/slice the files into 5 let say and tar+gz it at one time....

and whenever i want to restore it, i coould just restore it will combined together again?

You will also need to enable support for large files on your filesystem if you have not already do so...

Create a shell script under a file, named Split_export.sh

# -b1000m indicates to split command to split the input file into every 1000 MB size.

# As it splits, the split command will suffix aa, ab, ac, ad ... upto zz to the file name specified.

After saving the above three commands in split_export.sh, execute the following.
=======================================================================

chmod a+x split_export.sh

nohup split_export.sh > /tmp/split_export.log 1>&2 &

=======================================================================
After a few minutes you should see files in the export dump directory.

Create a shell script with the following command under the file name split_import.sh.

After creating provide execution permission to this script as follows:
======================================================================

Chmod a+x split_import.sh

# The import script assumes in this example that the above export script created 2 split files

# called expfileaa and expfileab. The order of the file for the cat command is very important.

nohup cat /dumpdir/expfileaa /dumpdir/expfileab > /dev/split_pipe &

# sleep 3 seconds

Sleep 3

nohup uncompress < /dev/split_pipe > /dev/compress_pipe &

#Sleep at this point is very important as some time is needed to uncompress the file and send it to the pipe.

sleep 60

imp username/password file=/dev/compress_pipe and other parameters for export.

nohup split_import.sh > /tmp/split_import.log 1>&2 &

=======================================================================
Wait for the import to finish.
