This parameter is ignored by the new diagnosability infrastructure introduced in Oracle Database 11g Release 1, which places trace and core files in a location controlled by the DIAGNOSTIC_DEST initialization parameter.
第八步：调整pfile参数文件，并创建spfile文件后启动
打开pfile文件，可以看到两个弃用的参数后面都有注释“#Deprecate parameter”
将两个废弃的参数注释，然后生成spfile文件后启动
SYS@cams>create spfile from pfile;
File created.
SYS@cams>startup;
ORACLE instance started.

第九步：模拟在第六步的时候未能及时发现参数文件被误删除，然后数据库关闭了，启动的时候报错。
