解决：

1. 查看是否有spfile:

SQL> show parameter spfile;
NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
spfile                               string

2. 从pfile创建spfile

SQL> create spfile from pfile;
File created.

3. 关闭数据库

SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.

4. 启动数据库

SQL> startup;
ORACLE instance started.

5. 查看是否有spfile文件

SQL> show parameter spfile;

------------------------------------ ----------- ------------------------------
spfile                               string      /opt/oracle/product/11.2.0/dbn
                                                 ame_1/dbs/spfileORCL.ora

6. 再次执行该命令，问题解决

SQL> alter system set processes=500 scope=spfile;
System altered.
