包括了: 查正在运行的SQL语句, 某个服务中的session 表空间管理 锁状态 数据库中当前活跃用户信息 。。。。 这些代码来至于dbadmin 项目 是一个美国的DBA 写的 不错,在googlde code中的 有 PL/SQL DBA g_sid v$session.SID%type := '-1'; g_serial# v$sess
包括了:g_sid v$session.SID%type := '-1'; g_serial# v$session.SERIAL#%type; g_terminal v$session.TERMINAL%type; g_username v$session.username%type; function get_object_by_id(p_object_id in number) return varchar2 is l_object_name varchar2(1000); begin select owner || '.' || object_name into l_object_name from dba_objects where object_id = p_object_id; return l_object_name; exception when others then return p_object_id; end; function get_objects_locked_by_session(p_sid in number) return varchar2 is l_result varchar2(1000) := ''; cursor locks is select get_object_by_id(id1) locked_object from v$lock where type = 'TM' and sid = p_sid; begin for c in locks loop if l_result is not null then l_result := l_result || chr(10); end if; l_result := l_result || c.locked_object; end loop; return l_result; end; procedure get_session_info(p_sid in number) is begin select serial#, terminal, username into g_serial#, g_terminal, g_username from v$session where sid = p_sid; end get_session_info; function get_session_serial#(p_sid in number) return v$session.SERIAL#%type is begin if p_sid != g_sid then get_session_info(p_sid); end if; return g_serial#; end get_session_serial#; function get_session_terminal(p_sid in number) return v$session.terminal%type is begin if p_sid != g_sid then get_session_info(p_sid); end if; return g_terminal; end get_session_terminal; function get_session_username(p_sid in number) return v$session.username%type is begin if p_sid != g_sid then get_session_info(p_sid); end if; return g_username; end get_session_username; function get_sids(p_process in varchar2) return varchar2 is cursor users_sids is select sid, module, program from v$session s where s.process = p_process or s.process like p_process || ':%'; result varchar2(1000); begin result := ''; for c in users_sids loop if c.program = 'JDBC Thin Client' then result := 'Web sessions'; else if result is not null then result := result || chr(10); end if; result := result || to_char(c.sid) || ' ' || nvl(c.module, 'Main Menu'); end if; end loop; return result; end; --还有很多 见附件 。。。。。。
