ulimit for oracle10
Hello,
I have an es45 4Go ram on 5.1b patchkit 6 and we want to install oracle10g.
I want to increase the data limit for oracle10 user, but the command ulimit -d 1024000 sent me "exceeds allowable limit"
I think kernel parametters are ok but i don't understand how can i increase this.
Thank for your help

Re: ulimit for oracle10
Francois,
Your kernel parameters are NOT ok.
They do not follow the requirements as documented by Orace in Ch 2, "Configure Kernel Subsystem Attributes" in the installation guide:
http://www.oracle.com/pls/db102/to_pdf?pathname=install.102%2Fb25300.pdf&remark=portal+%28Getting+Started%29
Specifically, the stack_size setting is silly. Recommended is 32M, max is really 512M, not 2G.
The Address Space settings also appear excessive, but that should be ok.
Be sure to also check out:

Hope this helps some,
