表:

  select * from cat;

  select * from tab;

  select table_name from user_tables;

视图:

  select text from user_views where view_name=upper('&view_name');

索引:

  select index_name,table_owner,table_name,tablespace_name,status from user_indexes order by table_name;

触发器:

  select trigger_name,trigger_type,table_owner,table_name,status from user_triggers;

快照:

  select owner,name,master,table_name,last_refresh,next from user_snapshots order by owner,next;

同义词:

  select * from syn;

序列:

本用户读取其他用户对象的权限:

  select * from user_tab_privs;

本用户所拥有的系统权限:

  select * from user_sys_privs;

用户:

  select * from all_users order by user_id;

表空间剩余自由空间情况:

  select tablespace_name,sum(bytes) 总字节数,max(bytes),count(*) from dba_free_space group by tablespace_name;

数据字典:

  select table_name from dict order by table_name;

锁及资源信息:

  select * from v$lock;不包括DDL锁

数据库字符集:

  select name,value$ from props$ where name='NLS_CHARACTERSET';

inin.ora参数:

SQL共享池:

  select sql_text from v$sqlarea;

数据库:

  select * from v$database

控制文件:

  select * from V$controlfile;

重做日志文件信息:

  select * from V$logfile;

来自控制文件中的日志文件信息:

  select * from V$log;

来自控制文件中的数据文件信息:

  select * from V$datafile;

NLS参数当前值:

  select * from V$nls_parameters;

ORACLE版本信息:

  select * from v$version;

描述后台进程:

  select * from v$bgprocess;

查看版本信息:

  select * from product_component_version;

2.  监控数据库

select '查看数据库的版本' from dual;

Select version FROM Product_component_version Where SUBSTR(PRODUCT,1,6)='Oracle';

 

select '查看数据库库对象' from dual;

select owner, object_type, status, count(*) count# from all_objects group by owner, object_type, status;

 

select '查看数据库的创建日期和归档方式' from dual;

Select Created, Log_Mode, Log_Mode From V$Database;

 

select '查看控制文件' from dual;

select name from v$controlfile;

 

select '查看表空间的名称及大小' from dual;

select t.tablespace_name, round(sum(bytes/(1024*1024)),0) ts_size from dba_tablespaces t, dba_data_files d where t.tablespace_name = d.tablespace_name group by t.tablespace_name;

 

select '查看表空间物理文件的名称及大小' from dual;

select tablespace_name, file_id, file_name, round(bytes/(1024*1024),0) total_space from dba_data_files order by tablespace_name;

 

select '查看表空间的使用情况' from dual;

select sum(bytes)/(1024*1024) as free_space,tablespace_name from dba_free_space group by tablespace_name ;

SELECT A.TABLESPACE_NAME,A.BYTES TOTAL,B.BYTES USED, C.BYTES FREE, (B.BYTES*100)/A.BYTES "% USED",(C.BYTES*100)/A.BYTES "% FREE"

FROM SYS.SM$TS_AVAIL A,SYS.SM$TS_USED B,SYS.SM$TS_FREE C

WHERE A.TABLESPACE_NAME=B.TABLESPACE_NAME AND A.TABLESPACE_NAME=C.TABLESPACE_NAME;

 

select '查看日志文件' from dual;

select member from v$logfile;

 

select '查看回滚段名称及大小' from dual;

select segment_name, tablespace_name, r.status, (initial_extent/1024) InitialExtent,(next_extent/1024) NextExtent, max_extents, v.curext CurExtent From dba_rollback_segs r, v$rollstat v Where r.segment_id = v.usn(+) order by segment_name;
