ORA-00600: internal error code, arguments: [4194]
4193：表示undo和redo不一致（Arg [a] Undo record seq number，Arg [b] Redo record seq number ）；
4194：表示也是undo和redo不一致（Arg [a] Maximum Undo record number in Undo block，Arg [b] Undo record number from Redo block）
故障解决：
1、修改参数
undo_management= MANUAL
undo_tablespace= SYSTEM
2、OPEN数据库，删除当前undo空间，重建新的undo空间
3、修改参数
undo_management= AUTO
undo_tablespace= UNDOTBS1
4、重新启动数据库

使用PlateSpin复制出来的一数据库服务器（Oracle 10g）在启动数据库实例时遇到“ORA-00600: internal error code, arguments: [4194].....”错误，实例在启动后，会自然Down掉。具体情况如下所示：

这个错误，官方文档Step by step to resolve ORA-600 4194 4193 4197 on database crash (文档 ID 1428786.1)有提供详细的介绍。建议处理前，建议先查阅次文档，错误出现的主要场景：
This issue generally occurs when there is a power outage or hardware failure that initially crashes the database. On startup, the database does the normal roll forward (redo) and then rollback (undo), this is where the error is generated on the rollback.
具体操作如下所示
Step 1: 通过spfile创建生成pfile
SQL> create pfile from spfile;
File created.
Step 2: 关闭数据库实例。
Step 3：修改pfile中undo_management为MANUAL
[oracle@DB-Server dbs]$ grep undo initepps.ora
*.undo_management='AUTO'
*.undo_tablespace='UNDOTBS'
[oracle@DB-Server dbs]$ vi initepps.ora
Step 4: 使用PFILE启动数据库
[oracle@DB-Server dbs]$ sqlplus / as sysdba

Redo Buffers 14671872 bytes

Database opened.
Step 5：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. There are many options from this moment and Oracle Support Analyst can offer different solutions for the bad undo segments.
If all offline then continue to the next step
SQL> select tablespace_name, status, segment_name from dba_rollback_segs where status != 'OFFLINE';
TABLESPACE_NAME STATUS SEGMENT_NAME
------------------------------ ---------------- ------------------------------
SYSTEM ONLINE SYSTEM
Step 6： 新建一个UNDO表空间
SQL> create undo tablespace UNDOTBS1
2 datafile '/u04/epps/oradata/undotbs_01.dbf'
3 size 4G;
Tablespace created.
Step 7： 删除旧的UNDO表空间
SQL> drop tablespace UNDOTBS including contents and datafiles;
Tablespace dropped.
Step 8：关闭数据库实例
SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> exit
Disconnected from Oracle Database 10g Release 10.2.0.4.0 - 64bit Production
Step 9：启动数据库实例到NOMOUNT状态

Step 10：修改spfile中的undo_tablespace参数
SQL> alter system set undo_tablespace='UNDOTBS1' scope=spfile;
System altered.

Step 12：启动数据库实例（使用spfile）

| Step by step to resolve ORA-600 4194 4193 4197 on database crash (文档 ID 1428786.1) |
In this Document

| Changes |
| Cause |
| Solution |
APPLIES TO:
Oracle Database - Enterprise Edition - Version 9.2.0.1 to 11.2.0.3 [Release 9.2 to 11.2]
Information in this document applies to any platform.
***Checked for relevance on 04-Dec-2013***
SYMPTOMS
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.
CHANGES
This issue generally occurs when there is a power outage or hardware failure that initially crashes the database. On startup, the database does the normal roll forward (redo) and then rollback (undo), this is where the error is generated on the rollback.
CAUSE
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
SOLUTION
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=
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. There are many options from this moment and Oracle Support Analyst can offer different solutions for the bad undo segments.
If all offline then continue to the next step
5. Create new undo tablespace - example
>create undo tablespace datafile size 2000M;
6. Drop old undo tablespace
>drop 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 = '' 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.
