ulimit -d problems

[ellaia adil]

Hi,
i want to set ulimit for user Oracle to 4000000.
i set "unlimited" as hard limit, but when i try to set 4000000 to soft limit, it doesn't work.
thx.

[crm-prd1]/home/oracle>ulimit -Hd unlimited
[crm-prd1]/home/oracle>ulimit -Hd
unlimited
[crm-prd1]/home/oracle>ulimit -d
2000000
[crm-prd1]/home/oracle>ulimit -d 4000000
su: ulimit: The specified value exceeds the user's allowable limit.

Your value is exceeding maxdsiz kernel setting.

What are your settings for maxdsiz and maxdsiz_64bit?

# kmtune | grep maxdsiz

Hi,
maxdsiz 2147483648
maxdsiz_64bit 2147483648

Hi,

You will need to increase these parameters and recompile your kernel.

Here's the relevant chapter from HP's SW Recovery Handbook:

You can also use 'sam' to do this.
