Я достаточно долго охотился за этим документом, который в свое время был на металинке, но потом, видимо, по нежеланию обновлять его работники Oracle его убрали. Полагаю, что много информации актуально и до сих пор. Нашел на китайском сайте. Напоминаю, что очень ценная информация на металинке находится по поиску ORA-600 error lookup tool.

Как известно, в ошибка ORA-600 сопровождается двумя параметрами. Первый параметр - это либо число, которое отражает исходный компонент или слой, с которым связана ошибка; или
первый параметр - мнемоника, которая указывает исходный модуль, где произошла ошибка.

Итак, список по числам

1 Service Layer
The service layer has within it a variety of service related components which are associated with in memory related activities in the SGA such as, for example : the management of Enqueues, System Parameters, System state objects (these objects track the use of structures in the SGA by Oracle server processes), etc.. In the main, this layer provides support to allow process communication and provides support for locking and the management of structures to support multiple user processes connecting and interacting within the SGA.
Note : vos - Virtual Operating System provides features to support the functionality above. As the name suggests it provides base functionality in much the same way as is provided by an Operating System.
Код:
1	vos	Component notifier
100	vos	Debug
300	vos	Error
500	vos	Lock
700	vos	Memory
900	vos	System Parameters
1100	vos	System State object
1110	vos	Generic Linked List management
1140	vos	Enqueue
1180	vos	Instance Locks
1200	vos	User State object
1400	vos	Async Msgs
1700	vos	license Key
1800	vos	Instance Registration
1850	vos	I/O Services components
2000 Cache Layer
Where errors are generated in this area, it is advisable to check whether the error is repeatable and whether the error is perhaps associated with recovery or undo type operations; where this is the case and the error is repeatable, this may suggest some kind of hardware or physical issue with a data file, control file or log file. The Cache layer is responsible for making the changes to the underlying files and well as managing the related memory structures in the SGA.
Note :rcvindicates recovery. It is important to remember that the Oracle cache layer is effectively going through the same code paths as used by the recovery mechanism.

Код:
2000	server/rcv	Cache Op
2100	server/rcv	Control File mgmt
2200	server/rcv	Misc (SCN etc.)
2400	server/rcv	Buffer Instance Hash Table
2600	server/rcv	Redo file component
2800	server/rcv	Db file
3000	server/rcv	Redo Application

3400	server/rcv	Archival & media recovery component
3600	server/rcv	recovery component
3700	server/rcv	Thread component
3800	server/rcv	Compatibility segment
It is important to consider when the error occurred and the context in which the error was generated. If the error does not reproduce, it may be an in memory issue.

4000 Transaction Layer
Primarily the transaction layer is involved with maintaining structures associated with the management of transactions. As with the cache layer , problems encountered in this layer may indicate some kind of issue at a physical level. Thus it is important to try and repeat the same steps to see if the problem recurs.

Код:
4000	server/txn	Transaction Undo
4100	server/txn	Transaction Undo
4210	server/txn	Transaction Parallel
4250	server/txn	Transaction List
4300	space/spcmgmt	Transaction Segment
4400	txn/lcltx	Transaction Control
4450	txn/lcltx	distributed transaction control
4500	txn/lcltx	Transaction Block
4600	space/spcmgmt	Transaction Table
4800	dict/rowcache	Query Row Cache
4900	space/spcmgmt	Transaction Monitor
5000	space/spcmgmt	Transaction Extent
It is important to try and determine what the object involved in any reproducible problem is. Then use the analyze command. For more information, please refer to the analyze command as detailed in the context of Note:28814.1; in addition, it may be worth using the dbverify as discussed in Note:35512.1.

6000 Data Layer
The data layer is responsible for maintaining and managing the data in the database tables and indexes. Issues in this area may indicate some kind of physical issue at the object level and therefore, it is important to try and isolate the object and then perform. an anlayze on the object to validate its structure.

Код:
6000	ram/data
        ram/analyze
        ram/index	data, analyze command and index related activity
7000	ram/object	lob related errors
8000	ram/data	general data access
8110	ram/index	index related
8150	ram/object	general data access
Again, it is important to try and determine what the object involved in any reproducible problem is. Then use the analyze command. For more information, please refer to the analyze command as detailed in the context of Note:28814.1; in addition, it may be worth using the dbverify as discussed in Note:35512.1.

12000 User/Oracle Interface & SQL Layer Components
This layer governs the user interface with the Oracle server. Problems generated by this layer usually indicate : some kind of presentation or format error in the data received by the server, i.e. the client may have sent incomplete information; or there is some kind of issue which indicates that the data is received out of sequence

Код:
12200	progint/kpo
        progint/opi	lob related
                        errors at interface level on server side, xa , etc.
