corn jobs not working properly

Hi There,

I have a script in cron that copy my data files from one folder to another on daily basis, some of the data files are larger than 2 GB, and /var/mail/oracle is showing me following errors regarding the script execution:

cp: /u02/oradata/TABSTST/TABS_DATA01.dbf: File too large

a /u01/daily_cold_backup/TABSTST/system01.dbf 819216 blocks
a /u01/daily_cold_backup/TABSTST/undotbs01.dbf 4014096 blocks
Can't open /dev/tty to prompt for more media.

Would you help me in this respect please?

Re: corn jobs not working properly

Your second list looks like it i tar's 'v' output. Unless patched, tar has a 2 GiB filesize limit. Since you didn't bother to indicate your OS version, I won't bother to look up the appropriate patch but the patched version of tar (of the Gnu version) will support a maximum filesize of 8GiB. Look in that patch database for tar.
If it ain't broke, I can fix that.

Re: corn jobs not working properly


If you are using 'cp' and receive a "file too large" error, then your destination filesystem probably doesn't have 'largefiles' enabled. There are several easy ways to ascertain whether or not a filesystem supports largefiles:

# fsadm -F vxfs /mountpoint

# mkfs -m -F vxfs /dev/vgXX/lvolN

...either will show 'largefiles' or 'nolargefiles'.

If you find that you need to convert a nolargefiles to a largefiles filesystem, do:

# fsadm -F vxfs -o largefiles /mountpoint

...if you have OnlineJFS installed. Otherwise you will need to unmout the filesystem and do:

# fsadm -F vxfs -o largefiles /dev/vgXX/rlvolN

*Note* the use of the raw device --- 'rlvolN'.

As for an 11.11 version of 'tar' that supports files up to 8GB in size, you can install:


No reboot is required.
