Oracle 19c故障恢复

发表于 2020 年 3 月 10 日由惜分飞

有客户找到我们,他们的oracle 19c数据库由于异常断电,导致启动异常,经过一系列恢复之后,依旧无法解决问题,请求我们给予支持.通过我们的Oracle数据库异常恢复检查脚本(Oracle Database Recovery Check),获取数据库当前信息如下:
数据库版本为19C并且安装了19.5.0.0.191015 (30125133)补丁

数据库使用pdb

数据库启动成功后,一会就crash掉

通过报错信息判断,数据库open之后(特别是pdb 4 open之后),开始报ORA-600 4193错误.然后由于CLMN进程异常,最后数据库crash.对于这类故障,因为使用的pdb,而且是由于pdb的undo异常导致数据库启动之后crash,可以通过对于pdb进行特殊处理,从而实现数据库启动之后不再crash.

ORA-600 4194/ORA-600 4193/ORA-600 4137故障解决

发表于 2016 年 8 月 4 日由惜分飞

对于常见的undo异常错误,ORA-600 4193,ORA-600 4194,ORA-600 4137等错误的处理一般步骤.
适用版本

Oracle Database - Enterprise Edition - Version 9.2.0.1 to 11.2.0.4 [Release 9.2 to 11.2]
Information in this document applies to any platform.

报错现象

The following error is occurring in the alert.log right before the database crashes.

ORA-00600: internal error code, arguments: [4194], [#], [#], [], [], [], [], []

This error indicates that a mismatch has been detected between redo records and rollback (undo) records.

ARGUMENTS:

Arg [a] - Maximum Undo record number in Undo block
Arg [b] - Undo record number from Redo block

Since we are adding a new undo record to our undo block, we would expect that the new record number
 is equal to the maximum record number in the undo block plus one. Before Oracle can add 
a new undo record to the undo block it validates that this is correct. If this validation fails,
 then an ORA-600 [4194] will be triggered.

报错原因

This also can be cause by the following defect

Bug 8240762 Abstract: Undo corruptions with ORA-600 [4193]/ORA-600 [4194] or ORA-600 [4137] after SHRINK

Details: 
Undo corruption may be caused after a shrink and the same undo block may be used 
for two different transactions causing several internal errors like:
ORA-600 [4193] / ORA-600 [4194] for new transactions
ORA-600 [4137] for a transaction rollback

处理步骤

Best practice to create a new undo tablespace.
This method includes segment check.

Create pfile from spfile to edit
>create pfile from spfile;

1. Shutdown the instance

2. set the following parameters in the pfile
    undo_management = manual
    event = '10513 trace name context forever, level 2'

3. >startup restrict pfile=<initsid.ora>

4. >select tablespace_name, status, segment_name from dba_rollback_segs where status != 'OFFLINE';

This is critical - we are looking for all undo segments to be offline - System will always be online.

If any are 'PARTLY AVAILABLE' or 'NEEDS RECOVERY' - Please open an issue with Oracle Support or update the current SR.

If all offline then continue to the next step

5. Create new undo tablespace - example
>create undo tablespace <new undo tablespace> datafile <datafile> size 2000M;

6. Drop old undo tablespace
>drop tablespace <old undo tablespace> including contents and datafiles;

7. >shutdown immediate;

8 >startup nomount;  --> Using your Original spfile

9 modify the spfile with the new undo tablespace name

  Alter system set undo_tablespace = '<new tablespace created in step 5>' scope=spfile;

10. >shutdown immediate;

11. >startup;  --> Using spfile
 


The reason we create a new undo tablespace first is to use new undo segment numbers
 that are higher then the current segments being used.
This way when a transaction goes to do block clean-out 
the reference to that undo segment does not exist and continues with the block clean-out.
