ORA-00600ORA-01565ORA-27046 - 数据库编程

昨天在做数据泵导入导出的时候，突然遇到ude-00008错误，查看日志文件：

Errors in file /oracle/afcprd01/db/10.2.0/admin/afcprd01_afcdb/bdump/afcprd01_dbw0_1417220.trc:

Instance terminated by DBW0, pid = 1417220

数据库已经宕机了，spfile损坏了，具体怎么损坏的，也不清楚。既然如此，就只有恢复spfile了。

MOS上面给出非常详细的方案：

ORA-600 [kmgs_parameter_update_timeout_1], [1565], Instance Terminated, Can't Startup Using Either Pfile Or Spfile (Doc ID 960080.1)

Now, database can not be started using either pfile or spfile.

CAUSE

In this case, this is looking spfile corruption issue, due to which database can not be open, but pfile is also having some problem, possibly some junk character is there, which not allowing to open the database using pfile.

SOLUTION

To solve the issue related to corrupted PFILE/SPFILE , please follow the below steps.

- Restore any old valid pfile / spfile from backup

- If the backup of the pfile / spfile is not available , try to get the instance startup parameters from the alert log from last startup.

- If the backup of the pfile / spfile nor old alert log is not available , follow the below steps:

Startup the database in restricted mode using a new pfile.
This new pfile should be created using old pfile by copying all the parameters one-by-one.

First make it with minimum values, just to startup and check the possibility that there is even a problem with the new pfile.

-- If it is unsuccessful, then there might be an issue with new pfile also.
-- Now, edit and copy all the parameters in it one-by-one from old pfile.
-- Open the database with new pfile again.
-- Once database is open, create spfile from this new pfile.
-- Shutdown the database.
-- Startup the database with the spfile now.
