[omar abdullah]

Hi My dear

i have hp rp8400 with hpux 11i

how to increase ulimit file to 4GB in hpux
or increase it to ulimit

Regards
A. Omar

[Deepak Kr]

Omar,

Provide following:
#uname -a
#ulimit -a

and

#kmtune -q maxdsiz
or
#kctune -q maxdsiz

[Fabio Ettore]

Hi,

has your filesystem largefiles enabled?

Check that by

fsadm -F vxfs /

Best regards,
Fabio

[Sandeep_Chaudhary]

ulimit -f 8388608

add the same entry in .profile of user . if u want to apply this to everybody add to /etc/profile

[Deepak Kr]

Check kernel paramters mentioned above and then hard limits set otherwise you will get error when you will try changing beyond limit

shpu12:rsh:/home/dc93650>ulimit -aH

coredump(blocks) unlimited

Hi,

'limit file is 2 G in HPUX 11i'
As Fabio said, you have to check if it's an ulimit problem or a non-largefile system problem.
Do you have problems to store more than 2 GB of files or to store one file with more than 2 GB?

I have problems to store one file with more than 2 GB
and in export from oracle the dump file reach only to 2 GB

Is the output filesystem set for largefiles ??? !!!!!!

[omar abdullah]

HI MydEAR

I need configure ulimit in my system to large file (4 GB)
please giv me steps for that

Hi :

To enable 'largefiles' (those exceeding 2GB) for an existing filesystem, do:

# fsadm -F vxfs -o largefiles /dev/vg02/rlvol1

To enable 'largefiles' when you create the filesystem:

newfs -F vxfx -o largefiles /dev/vg02/rlvol1

To see the current 'largefiles' setting, do:

# fsadm -F vxfs /dev/vg02/rlvol1

Regards!

Hmmm.. asked for output from mount command and got a pile of kernel params :(

Oh well...

[V. Nyga]

Hi again,

you said:
data(kbytes) 262144
stack(kbytes) 8192

So your data is limited to 256 MB.
If you can create files till 2 GB than is THIS not your problem.
Your problem seems to be that your file system is not configured to store files larger than 2GB.
So check our answers and test it either with JRF's or Fabio's command or:

# fstyp -v /dev/vg00/lvol3 |grep -i f_flag

! For /dev/vg00/lvol3 you have to use the device where you want to store the files!

if f_flag: 0 then max 2 GB
if f_flag: 16 then max 8 GB

Can you give us the messages of these commands?

Hi again,

to increase ulimit check the usage of ulimit:
'man ulimit'

Do you have access to the 'Technical knowledge base'?:
http://www12.itrc.hp.com/service/cki/docDisplay.do?docLocale=en&docId=emr_na-c01005257-2

http://www12.itrc.hp.com/service/cki/docDisplay.do?docLocale=en&docId=emr_na-c01513482-1

http://www12.itrc.hp.com/service/cki/docDisplay.do?docLocale=en&docId=emr_na-c00905065-10

Also:
1. Log in as root.
2. Use ulimit() to check settings:
# ulimit -a
3. Reset ulimit() to its maximum value:
# ulimit -d 65536 oracle
4. Have the Oracle user log off and back on.

Volkmar

[V. Nyga]

Also - Shell: running ksh script in POSIX shell to exceed 2 GB ulimit:
