搭建測試環境後出現的問題
仍然是很久以前的記錄
ORA-03113&ORA-07445;
今天weblogic jdbc突然中斷幾次，導致系統無法登陸，登陸時錯誤提示為：

重置JDBC後，可以正常使用，但是過20多分鐘問題依舊。
我同時連線的會話卻一直正常，沒有出現過網路中斷。
心裡這時想的是肯定是應用開發有問題，本來這個測試環境就是上的新版本應用嘛。
出於職業習慣，檢查了一下alert檔案（原來是沒有做日誌監控的，現在包括測試庫，自動10分鐘日誌監控，應該可以避免問題沒有及時發現），發現有如下提示：

對照時間，和發生問題的時間一樣，
靠，居然還是我資料庫的問題。
開啟其中一個跟蹤檔案：

上網去查詢ora-07445的內容，其中有一個建議是如下的：
oracle的BUG，在初始化檔案裡面設定引數
alter system set event = "10262 trace name context forever, level 1024000" scope=spfile;
重啟再看看還會不會產生這種錯誤。
按照這個方法作修改，重啟資料庫，10多分鐘後，問題又來了。
苦於沒有metlink帳號（付了錢的，但是過了半年還沒有拿到帳號），還是仔細看看跟蹤檔案的提示吧。
看了一會兒還是看不出什麼問題，不過每個檔案裡面都有以下的語句
Current SQL statement for this session:
select count(*) from GuPolicyCopyMain em,GuPolicyCopyRisk er,GuPolicyCopyEndorHead eh where em.policyNo=er.policyNo and em.endorSeqNo=er.endorSeqNo and er.policyNo=eh.policyNo and er.endorSeqNo=eh.endorSeqNo and em.endorSeqNo!='000' AND (em.policyNo = 'PFNU03004403') AND (er.uwYear = '2007') AND (eh.validInd = '1') AND (eh.inputDate>=to_date('2007-12-06', 'YYYY-MM-DD HH24:MI:SS')) AND (eh.underWriteInd = '6')
引起了注意，好歹看看這句語句吧。執行這句語句，報ORA-03113的錯誤。
問題根源找到！！！！！！！！！！！
單獨查詢任何一個表都是沒有問題的。
懷疑是約束或索引有問題，先禁用掉這些表的約束試試吧。
禁用掉這些表相關的約束後，再執行這條語句，成功執行。
為了找出哪個表有問題，只得一個個表啟用約束，在看是否可以執行，終於在執行啟用GuPolicyCopyRisk的
pk_rf91時，約束一啟用，執行那條語句就有ORA-03113的錯誤。
解決辦法：
刪掉主鍵pk_rf91，
用drop constraint pk_rf91時，提示有外來鍵引用到這個主鍵，不讓刪。
先禁用掉所有的外來鍵吧，結果還是一樣的問題。
於是來一招狠的吧，drop constraint pk_rf91 cascade（刪之前查一下有哪些外來鍵應用這個約束，並且獲得生成他們的語句，這個主鍵可是有11個外來鍵引用呢！）
再重新生成主鍵，外來鍵。
按照此方法執行，到目前為止是沒有異常了。
