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.

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.

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.

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.
