Oracle日常治理用到的一些sql语句 继续添加中 表空间及容量: select tablespace_name,sum(bytes)/1024/1024/1024 from dba_data_files group by tablespace_name; 表空间的空闲容量: select tablespace_name,sum(bytes) from dba_free_space group by tablespace_name; 系统表空间: select tablespace_name from dba_tablespaces; 系统数据文件: select file_name from dba_data_files; 系统控制文件: select value from v$parameter where name='control_files'; 系统重做日志文件: select member from v$logfile; 归档日志文件: select value from v$parameter where name='log_archive_dest';
