ORA-12754: Feature ‘startup’ is disabled due to missing capability ‘Runtime Environment’

ORACLE 18C启动报ORA-12754
从http://edelivery.oracle.com网上可以下载oracle 18c for exadata,在普通的linux平台可以正常安装,但是无法正常启动实例(dbca无法创建库),报错信息为:ORA-12754: Feature ‘startup’ is disabled due to missing capability ‘Runtime Environment’.

---

由于普通的linux而非真实oracle一体机,而该版本中做了限制,因此无法启动数据库.根据oracle的作风,对于引进的新特性,oracle一般都提供隐含参数或者event控制,通过分析确定有_exadata_feature_on参数进行控制.
修改脚本创建库参数
由于我们无法在dbca图形化的界面中增加新参数,因此可以通过生成创建库脚本,然后通过修改参数文件,增加_exadata_feature_on=true

[oracle@xifenfei scripts]$ ls -ltr *.ora
-rw-r----- 1 oracle oinstall 2252 Feb 28 09:22 init.ora
-rw-r----- 1 oracle oinstall 2264 Feb 28 09:28 initxffdbTempOMF.ora
-rw-r----- 1 oracle oinstall 2386 Feb 28 09:29 initxffdbTemp.ora

然后重新执行xffdb.sh脚本创建库

[oracle@xifenfei scripts]$ sh xffdb.sh
You should Add this entry in the /etc/oratab: xffdb:/u02/soft:Y
