SOLARIS 10 SHARE MEMORY

在solaris10上安装oracle,调整共享内存参数的问题
#projmod-a-K “project.max-shm-memory=(priv,4294967295,deny)” user.oracle

.....

在做完以上的参数配置后,查看/etc/project文件内容变为如下形式:

$ more project
system:0::::
user.root:1::::
noproject:2::::
default:3::::
group.staff:10::::
user.oracle:1233:oracle parameters:oracle::process.max-sem-nsems=(priv,256,deny);project.max-sem-ids=(priv,100,deny);project.max-shm-ids=(priv,100,deny);project.max-shm-memory=(priv,4294967295,deny)

使用prctl命令查看设置是否生效:

$ prctl -n project.max-shm-memory $$
process: 29333: -sh
NAME    PRIVILEGE       VALUE    FLAG   ACTION                       RECIPIENT
project.max-shm-memory
        privileged      4.00GB      -   deny                                 -
        system          16.0EB    max   deny                                 -
$

可以看到project.max-shm-memory值已经是4G了.
