Oracle数据库检查死锁的sql

实现代码如下：SELECT;;;SID,;DECODE;(BLOCK,;0,;'NO',;'YES');blocker,DECODE;(request,;0,;'NO',;'YES');waiterFROM;v$lockWHERE;request;>;0;OR;BLOCK;>;0ORDER;BY;BLOCK;DESC;SELECT;;;bs.username;'Blocking;User',;bs.username;'DB;User',ws.username;'Waiting;User',;bs.SID;'SID',;ws.SID;'WSID',bs.serial#;'Serial#',;bs.sql_address;'address',bs.sql_hash_value;'Sql;hash',;bs.program;'Blocking;App',ws.program;'Waiting;App',;bs.machine;'Blocking;Machine',ws.machine;'Waiting;Machine',;bs.osuser;'Blocking;OS;User',ws.osuser;'Waiting;OS;User',;bs.serial#;'Serial#',ws.serial#;'WSerial#',DECODE;(wk.TYPE,'MR',;'Media;Recovery','RT',;'Redo;Thread','UN',;'USER;Name','TX',;'Transaction','TM',;'DML','UL',;'PL/SQL;USER;LOCK','DX',;'Distributed;Xaction','CF',;'Control;FILE','IS',;'Instance;State','FS',;'FILE;SET','IR',;'Instance;Recovery','ST',;'Disk;SPACE;Transaction','TS',;'Temp;Segment','IV',;'Library;Cache;Invalidation','LS',;'LOG;START;OR;Switch','RW',;'ROW;Wait','SQ',;'Sequence;Number','TE',;'Extend;TABLE','TT',;'Temp;TABLE',wk.TYPE);lock_type,DECODE;(hk.lmode,0,;'None',1,;'NULL',2,;'ROW-S;(SS)',3,;'ROW-X;(SX)',4,;'SHARE',5,;'S/ROW-X;(SSX)',6,;'EXCLUSIVE',TO_CHAR;(hk.lmode));mode_held,DECODE;(wk.request,0,;'None',1,;'NULL',2,;'ROW-S;(SS)',3,;'ROW-X;(SX)',4,;'SHARE',5,;'S/ROW-X;(SSX)',6,;'EXCLUSIVE',TO_CHAR;(wk.request));mode_requested,TO_CHAR;(hk.id1);lock_id1,;TO_CHAR;(hk.id2);lock_id2,DECODE(hk.BLOCK,0,;'NOT;Blocking',;/**//*;Not;blocking;any;other;processes;*/1,;'Blocking',;;;;;/**//*;This;lock;blocks;other;processes;*/2,;'Global',;;/**//*;This;lock;is;global,;so;we;can't;tell;*/TO_CHAR;(hk.BLOCK));blocking_othersFROM;v$lock;hk,;v$session;bs,;v$lock;wk,;v$session;wsWHERE;hk.BLOCK;=;1AND;hk.lmode;! =;0AND;hk.lmode;!=;1AND;wk.request;!=;0AND;wk.TYPE(+);=;hk.TYPEAND;wk.id1(+);=;hk.id1AND;wk.id2(+);=;hk.id2AND;hk.SID;=;bs.SID(+)AND;wk.SID;=;ws.SID(+)AND;(bs.username;IS;NOT;NULL)AND;(bs.username;<>;'SYSTEM')AND;(bs.username;<>;'SYS')ORDER;BY;1;
