seting shm_max

[sachinonnet]

I am using solaris 10 for oracles. we created shell script to install oracle on solaris.

while setting shm_max for default project i am getting an error

prctl -n project.max-shm-memory -v 400gb -r -i project default

ERROR : prctl: default: No controllable process found in task, project, or zone.

to resolve this error i need to open one session for user whose project is set to default.

1. need to open / login to another user who it set to default project

su - oracle <<EOF!

2. set shm_max with root user permission

prctl -n project.max-shm-memory -v 400gb -r -i project default

is there a way to do both task from sigle script, i am executing scripts with root user permission and need to open an session in backgroud for user oracle.



thanks
Sachin

Well, this is not a Solaris forum. Have you looked for help on the Sun or Oracle web sites?

Thanks Rubberman,

we need to set same parameters and project on linux as well. i thought someone allready gone through similar issue on linux as well.

You can alter the system shmmax parameter with the sysctl tool. Look at the man page for systcl, the file /etc/sysctl.conf, and the header file /usr/include/linux/shm.h for more information.
