检查你的代码没有提前松散的LOB定位器（没有/没有任何改变它你得到LOB定位器后）：

SQL> create table t (x int, y clob);


SQL> declare
  2   l_y clob;
  3   buffer varchar2(10) := 'abcdef';
  4  begin
  5   -- You get clob locator
  6   insert into t values(1,empty_clob()) return y into l_y;
  7   -- you loose lob locator
  8   update t set y = empty_clob() where x = 1;
  9   -- you try to use lost locator
 10   dbms_lob.write(lob_loc => l_y, amount => 6, offset => 1, buffer => buffer );
 11  end;
 12  /
declare

error in line 1:
ORA-22922: nonexistent LOB value 
ORA-06512: in  "SYS.DBMS_LOB", line 1132 
ORA-06512: in  line 10

ORA-22922：jboss 6 eap中不存在LOB值错误
