1、查看datafile信息（文件號、是否在線和路徑名字）

select file#,status,name from v$datafile;

select file#,name,checkpoint_change# from v$datafile;
select file#,name,checkpoint_change# from v$datafile_header;

 

2、查看數據文件信息（文件號、對應的表空間、文件路徑、是否可用）

select file_id,tablespace_name,file_name,status from dba_data_files;

 

3、查看controlfile的路徑名字信息

select name from v$controlfile;

 

4、查看redo log組的狀態

select group#,sequence#,members,status from v$log;

 

5、查看redo log組文件狀態和成員信息（路徑和名字）

select group#,type,member from v$logfile;

 

6、查看歸檔日志信息

select name,sequence# from v$archived_log;

 

7、查看tablespace的信息

select file_name,file_id,tablespace_name,bytes/1024/1024 M,status from dba_data_files;

 

8、查看臨時文件的信息

select file#,status,enabled,bytes/1024/1024 M,name from v$tempfile;
