在T5-4中安装11.2.0.4 RAC，DBCA创建数据库时遇到ORA-27102 out of memory错误。

@db

T5-4的内存是1TB，我在设置project.max-shm-memory 参数时，设定800GB，DBCA创建数据库只给数据库400G的SGA，发生了这个错误。

把project.max-shm-memory 调小到128G，SGA给100G左右也不行。

1. oracle@dbcenter1: prctl -n project.max-shm-memory $
2. process: 33047: -bash
3. NAME    PRIVILEGE       VALUE    FLAG   ACTION                       RECIPIENT
4. project.max-shm-memory
5.         privileged       128GB      -   deny                                 -
6.         system          16.0EB    max   deny
