我们知道solaris上安装Oracle需要调整system参数。在solaris9中需要调整7个参数

noexec_user_stack
semsys:seminfo_semmni
semsys:seminfo_semmns
semsys:seminfo_semmsl
semsys:seminfo_semvmx
shmsys:shminfo_shmmax
shmsys:shminfo_shmmni

到了solaris10后，废弃了其中三个参数，并且不在建议直接修改system参数，而是使用命令修改。

如下4个参数（和原参数的对应关系参考官方文档）：

project.max-sem-ids
process.max-sem-nsems
project.max-shm-memory
project.max-shm-ids


查看系统参数
# id -p // to verify the project id
uid=0(root) gid=0(root) projid=1 (user.root)
# prctl -n project.max-shm-memory -i project user.root
# prctl -n project.max-sem-ids -i project user.root

修改系统参数

# prctl -n project.max-shm-memory -v 4gb -r -i project user.root
# prctl -n project.max-sem-ids -v 256 -r -i project user.root

# su - oracle
$ id -p
uid=100(oracle) gid=100(dba) projid=100(group.dba)
$ exit

# projmod -sK "project.max-shm-memory=(privileged,4G,deny)" group.dba
# cat /etc/project 验证查看

修改PID
