2GB size limitation using the "at" command

[Leo Rojas]

Is there a 2GB size limitation using the "at" command in 11.0? Even when I do a copy command using "at" it stops a 2GB, however when I don't use the "at" command I can run the same copy with files greater than 2GB's.

There are some commands that are limited to a 2 gig limit, as documented in the release notes in /usr/share/doc/10.20RelNotes or 11.0RelNotes.

Also, make sure that largefiles is enabled on the filesystem. There is also a white paper for this in /usr/share/doc/lg_files.txt.

Leo:

There have been many recent discussions on this. Do a search in the forums for "2GB" and "at". Hope this helps.

I think this is a problem caused by ulimit for your shell. There are a few possible workarounds;

1. Modify the file /var/adm/cron/.proto to change the line ulimit $1 to ulimit 4194303 or ulimit unlimited
2. change your shell to ksh and run ulimit unlimited before sudmitting the at job
3. do ulimit unlimited in your .profile

I would double check first that you have set up the file system as 'largefiles'. You can check this by doing:
# fsadm /dev/vg_name/rlvol_name (This will display largefiles or nolargefiles)
To change it to largefiles do:
#fsadm /dev/vg_name/rlvol_name
#umount /file_sys
#fsadm -o largefiles /dev/vg_name/rlvol_name (This changes it to largefiles..and you
then need to change your etc/fstab to reflect largefiles also)

I think my parameter settings for large files are correct because I don't have any problems copying files greater than 2G by themselves, but when I use the "at" command then it stops at 2. Any other suggestions?PLEASE...
