從上面的程式碼中，發現紅字部分正式出錯根源，錯誤號碼是ORA-00322和ORA-00312；

從網上檢視相關的文件，裡面說了一個解決辦法：

|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

今天有臺Oracle9i無法啟動，出現如下錯誤：
ora-00322:log 1of thread 1 is not current copy
ora-00312:online log 1thread 1:'opt/oracle/oradata/oradb/REDO02.LOG'

解決辦法如下：
1. shutdown  immediate;
2. startup mount;
3. alter database clear logfile 'opt/oracle/oradata/oradb/REDO02.LOG';
4. alter database open;
5. select status from v$instance;
看到Oracle可以正常啟動了；

登上去，做了類似的操做後，問題解決了。

Problem Description:
====================

You have a media failure, which causes the database to crash.

 
Problem Explanation:
====================

At startup, the database will mount, but gives the following errors at open:

  ORA-00312: "online log %s thread %s: '%s'"
      Cause: This message reports the filename for details of another message.
     Action: Other messages will accompany this message. See the
             associated messages for the appropriate action to take.

  ORA-00322: "log %s of thread %s is not current copy"
      Cause: Check of log file header at database open found that an online log
             appears to be an incorrectly restored backup.
     Action: Restore correct file or reset logs.

Search Words:
=============

Hardware, recover

Solution Description:
=====================

First check that ORACLE_HOME and ORACLE_SID are set correctly, and if not, do
so and re-start. Else, continue as follows.

Recover the loss of an inactive, online redo log group.

ALTER DATABASE CLEAR LOGFILE 'filename';

If there is more than one LOGFILE in the redo log group then you must
specify all the log files.

For example, the following fails:

SVRMGR> alter database clear logfile '/vobs/oracle/dbs/log3.log';
alter database clear logfile '/vobs/oracle/dbs/log3.log'
*
ORA-1514: error in log specification: no such log
ORA-1517: log member: '/vobs/oracle/dbs/log3.log

But, specifying all the log files in the group works:
SVRMGR> ALTER DATABASE CLEAR LOGFILE ('/vobs/oracle/dbs/t4.log','/vobs/oracle/;
Statement processed.

For more information Ref: Bug 763186

 
Solution Explanation:
=====================
 
The database, at open, does a check of log file headers and
found an online log that appears to be an incorrected restored file.
In this case it was not incorrect, but inactive. By issuing
the clear logfile, you can avoid going through an uneccessary
open resetlogs when applicable.
