Чтобы после перезагрузки их не потерять создадим проект:

projdel user.oradb

projadd -U oradb -K "project.max-shm-memory=(priv,150gb,deny)"  user.oradb
projmod -sK "process.max-stack-size=(privileged,9223372036854775807,deny)" user.oradb
projmod -sK "process.max-file-descriptor=(privileged,20480,deny)" user.oradb
projmod -sK "process.max-sem-nsems=(priv,1024,deny)" user.oradb
projmod -sK "project.max-sem-ids=(priv,512,deny)" user.oradb
projmod -sK "project.max-shm-ids=(priv,512,deny)" user.oradb


Или так:

# projadd group.dba
# usermod -K project=group.dba oradb
# usermod -K project=group.dba oragrid

# more /etc/project

system:0::::
user.root:1::::
noproject:2::::
default:3::::
group.staff:10::::
group.dba:100::::

# projmod -sK "project.max-shm-memory=(priv,150gb,deny)"  group.dba
# projmod -sK "process.max-stack-size=(privileged,9223372036854775807,deny)" group.dba
# projmod -sK "process.max-file-descriptor=(privileged,20480,deny)" group.dba
# projmod -sK "process.max-sem-nsems=(priv,1024,deny)" group.dba
# projmod -sK "project.max-sem-ids=(priv,512,deny)" group.dba
# projmod -sK "project.max-shm-ids=(priv,512,deny)" group.dba


Проверяем так:
# prctl -i project group.dba

# vi /etc/system
# Oracle:
set noexec_user_stack=1
