ORA-07455：估计执行时间（386781721秒），超过限制（86400秒）

Question

我正在尝试运行一个查询而其失败是由于＆＃34; ORA-07455：估计执行时间（386781721秒），超过限制（86400秒）＆＃34;

你能不能给我一些建议来解决这个问题？这是我试过的查询：

SELECT DISTINCT
    batch.id,
    UPPER(TRIM(NVL(t2.user_login, DECODE( INSTR(CAST(T.COLUMN_VALUE.EXTRACT('//text()') AS VARCHAR2(200)),'@',1,1),0,CAST(T.COLUMN_VALUE.EXTRACT('//text()') AS VARCHAR2(200)),
    SUBSTR(CAST(T.COLUMN_VALUE.EXTRACT('//text()') AS VARCHAR2(200)),1, (INSTR(CAST(T.COLUMN_VALUE.EXTRACT('//text()') AS VARCHAR2(200)),'@',1,1)-1)))))) AS USER_LOGIN,
    UPPER(CAST(t.COLUMN_VALUE.EXTRACT('//text()') AS VARCHAR2(200))) AS EMAIL_ADDRESS ,
    t1.BATCH_ID,
    t1.CREATED_BY
FROM
    message t1,
     TABLE( xmlsequence( XMLTYPE( '<x><x>'  || REPLACE(t1.RECIPIENTS, ',', '</x><x>')  || '</x></x>' ).EXTRACT('//x/*'))) t, --CHR(13)  ||CHR(10)
    BATCH,
  (
    SELECT DISTINCT
        user_login,
        sender
    FROM
        MESSAGE, BATCH
where BATCH.ID = MESSAGE.ID and BATCH.ID=1
  )
  t2
WHERE
    BATCH.BATCH_ID                                          = t1.BATCH_ID
    AND CAST(t.COLUMN_VALUE.EXTRACT('//text()') AS VARCHAR2(200)) = t2.sender(+) 
and t1.id=1
    ORDER BY   batch.id,  USER_LOGIN

这是我试图执行的查询。
