E' , 'OTHER' ) object_type , count(*) quantity from

sys.obj$ o where o.type# > 1 group by decode (o.type#,1,'INDEX' , 2,'TABLE' , 3

, 'CLUSTER' , 4, 'VIEW' , 5 , 'SYNONYM' , 6 , 'SEQUENCE' , 'OTHER' ) union select

'COLUMN' , count(*) from sys.col$ union select 'DB LINK' , count(*) from

22。按用户查看object种类

select u.name schema, sum(decode(o.type#, 1, 1, NULL)) indexes,

sum(decode(o.type#, 2, 1, NULL)) tables, sum(decode(o.type#, 3, 1, NULL))

clusters, sum(decode(o.type#, 4, 1, NULL)) views, sum(decode(o.type#, 5, 1,

NULL)) synonyms, sum(decode(o.type#, 6, 1, NULL)) sequences,

sum(decode(o.type#, 1, NULL, 2, NULL, 3, NULL, 4, NULL, 5, NULL, 6, NULL, 1))

others from sys.obj$ o, sys.user$ u where o.type# >= 1 and u.user# =

o.owner# and u.name <> 'PUBLIC' group by u.name order by

sys.link$ union select 'CONSTRAINT' , count(*) from sys.con$

23。有关connection的相关信息

1）查看有哪些用户连接

select s.osuser os_user_name, decode(sign(48 - command), 1, to_char(command),

'Action Code #' || to_char(command) ) action, p.program oracle_process,

status session_status, s.terminal terminal, s.program program,

s.username user_name, s.fixed_table_sequence activity_meter, '' query,

0 memory, 0 max_memory, 0 cpu_usage, s.sid, s.serial# serial_num

from v$session s, v$process p where s.paddr=p.addr and s.type = 'USER'

order by s.username, s.osuser

2）根据v.sid查看对应连接的资源占用等情况

select n.name, www.2cto.com

v.value,

n.class,

n.statistic#

from v$statname n,

v$sesstat v

where v.sid = 71 and

v.statistic# = n.statistic#

order by n.class, n.statistic#

3）根据sid查看对应连接正在运行的sql

select /*+ PUSH_SUBQ */

command_type,

sql_text,

sharable_mem,

persistent_mem,

runtime_mem,

sorts,

version_count,

loaded_versions,

open_versions,

users_opening,

executions,

users_executing,

loads,

first_load_time,

invalidations,

parse_calls,

disk_reads,

buffer_gets,

rows_processed,

sysdate start_time,

sysdate finish_time,

'>' || address sql_address,

'N' status

from v$sqlarea

where address = (select sql_address from v$session where sid = 71)
