Hi Charlotte,

you basically need these project definitions to define how much IPC resources can be used. The default setting calculated by the OS are not always what you want :-( Everything is allright except the allowed shared memory.
You need to define a project and kind of attach a max shared memory to it. I assume you already have a user 'oracle' and a group 'dba'. If not add these to you system.

Create a default project like:

projadd -c "Oracle default project" group.dba

This assigns a default project (called group.dba) to the UNIX group dba (the one that user oracle is a member of).

Now modify this project so adequate shared memory can be used:

projmod -sK "project.max-shm-memory=(privileged,2G,deny)" group.dba

Thats it. You can now use SGA up to 2G in size.

Good luck and have fun with that best OS in the world :-)

Cheers
Paul

Look in /etc/passwd, /etc/shadow, /etc/group and /etc/project to see how this info is stored in these files.
