测试增大db_files参数值

其实就是一句话，用alter system set db_files=xxx scope=spfile就可以了。
但是网络上有很多人说要修改重建控制文件才能完成云云。
此处就是测试。

在本机的hz2004实例上测试db_files参数扩充。

1。启动本机实例 net start oracleservicehz2004

2。sqlplus "/ as sysdba"
SQL> show parameter db_file;

NAME                               TYPE                   VALUE
------------------------------------ ---------------------- ------------------------------
db_file_multiblock_read_count       integer                16
db_file_name_convert                string
db_files                            integer                200

3。SQL> select file_name from dba_data_files;

FILE_NAME
--------------------------------------------------------------------------------
C:\ORACLE\ORADATA\HZ2004\SYSTEM01.DBF
C:\ORACLE\ORADATA\HZ2004\UNDOTBS01.DBF
C:\ORACLE\ORADATA\HZ2004\INDX01.DBF
C:\ORACLE\ORADATA\HZ2004\TOOLS01.DBF
C:\ORACLE\ORADATA\HZ2004\USERS01.DBF
C:\HZ2004DATA\HZ2004_CZRK.ORA
C:\HZ2004DATA\HZ2004_MLP.ORA
C:\HZ2004DATA\HZ2004_HXX.ORA
C:\HZ2004DATA\HZ2004_SFZ.ORA
C:\HZ2004DATA\HZ2004_PRM.ORA
C:\HZ2004DATA\HZ2004_PIC.ORA
C:\HZ2004DATA\HZ2004_SYS.ORA
C:\HZ2004DATA\HZ2004_IDX.ORA

13 rows selected

4。选定hz2004_sfz表空间进行测试，增加db_file(默认值为200)-13个文件（就是187个），以达到最大值。
每个数据文件1M。

DB_FILES[tr]PropertyDescription[/tr]

Parameter type	Integer
Default value	200
Modifiable	No
Range of values	Minimum: the largest among the absolute file numbers of the datafiles in the database Maximum: operating system-dependent
Basic	No
Real Application Clusters	Multiple instances must have the same value.

DB_FILES specifies the maximum number of database files that can be opened for this database. The maximum valid value is the maximum number of files, subject to operating system constraint, that will ever be specified for the database, including files to be added by ADD DATAFILE statements.
If you increase the value of DB_FILES, then you must shut down and restart all instances accessing the database before the new value can take effect. If you have a primary and standby database, then they should have the same value for this parameter.
