Question

由于以下参数，我无法在我的数据库中添加超过200个数据文件：

select records_total from v$controlfile_record_section where type = 'DATAFILE';
select value from v$parameter where name = 'db_files';

这两个都给我一个200的输出。我需要将此值增加到400，所以我尝试过：

alter system set records_total = 400 where name = 'db_files';
alter system set value= 400 where type = 'DATAFILE';

但我得到了小号

QL Error: ORA-02065: illegal option for ALTER SYSTEM
02065. 00000 -  "illegal option for ALTER SYSTEM"
*Cause:    The option specified for ALTER SYSTEM is not supported
*Action:   refer to the user manual for option supported

我可以更改这些参数以及如何更改？

你可能想要使用这样的命令：

这假设您正在使用SPFILE（或者您需要手动编辑init.ora文件并重新启动）并且您没有使用RAC（否则您将需要使用srvctl stop database -d my_sid之类的命令）

正如同样提到的，它可以帮助查看ALTER syntax。它也可能有助于查看Oracle Database Reference，它将告诉您命令是否是动态的（意味着它可以在不重新启动数据库的情况下运行）。

无法更改Oracle参数
