此前执行了CREATE SPFILE FROM MEMORY. 重新使用SPFILE启动时，出错如下：

解决方法：
1.先CREATE PFILE FROM SPFILE。
2.然后在PFILE里将background_dump_dest，user_dump_dest这两个参数删除。--在PFILE里可以看到这两个参数后面都显示的大致有参数deprecated.这种语句。如下：
*.user_dump_dest='/u01/app/oracle/product/11.2.0/dbhome_1/log/diag/rdbms/bys3/bys3/trace' #Deprecate parameter
3.重新使用CREATE SPFILE FROM PFILE，然后正常启动即可。
