oracle connection的相关信息

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, &nbs

  p;  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,

  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)
