查询Oracle 中死事务的语句
SQL> SELECT KTUXEUSN, KTUXESLT, KTUXESQN, /* Transaction ID */
2 KTUXESTA Status, KTUXECFL Flags ,KTUXESIZ
3 FROM x$ktuxe
4 WHERE ktuxesta!='INACTIVE';
KTUXEUSN KTUXESLT KTUXESQN STATUS FLAGS KTUXESIZ
---------- ---------- ---------- ---------------- ------------------------ ----------
13 5 47447 ACTIVE DEAD 2819919
39 0 502 ACTIVE NONE 1
43 45 480 ACTIVE NONE 0
SQL> /

---------- ---------- ---------- ---------------- ------------------------ ----------
13 5 47447 ACTIVE DEAD 2819919alter system set fast_start_parallel_rollback=false scope=both;
之后，再次运行
SQL> SELECT KTUXEUSN, KTUXESLT, KTUXESQN,/* Transaction ID */
2 KTUXESTA Status, KTUXECFL Flags ,KTUXESIZ
3 FROM x$ktuxe
4 WHERE ktuxesta!='INACTIVE';
KTUXEUSN KTUXESLT KTUXESQN STATUS FLAGS KTUXESIZ
---------- ---------- -------------------------- ------------------------ ----------

SQL> /
KTUXEUSN KTUXESLT KTUXESQN STATUS FLAGS KTUXESIZ
---------- ---------- -------------------------- ------------------------ ----------
13 5 47447 ACTIVE DEAD 2033433 set serveroutput on
SQL> declare
2 l_start number;
3 l_end number;
4 begin
5 select ktuxesiz into l_startfrom x$ktuxe where KTUXEUSN=13 and KTUXESLT=5;
6 dbms_lock.sleep(60);
7 select ktuxesiz into l_endfrom x$ktuxe where KTUXEUSN=13 and KTUXESLT=5;
8 dbms_output.put_line('time estDay:'|| round(l_end/(l_start -l_end)/60/24,2));
9 end;
10 /
time est Day:.21
24*0.21=5.04小时。即：预计5.04小时后回滚完毕。
另外注意：在其他环境使用时，请注意替换KTUXEUSN=13和KTUXESLT=5
