数字类型的Ora-600
Ora-600 Base Functionality Description
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.
 

Ora-600 Base Functionality Description
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 : rcv indicates 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.
 

Ora-600 Base Functionality Description
2000 server/rcv Cache Op
2100 server/rcv Control File mgmt 
2200 server/rcv Misc (SCN etc.)

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. 
 
Ora-600 Base Functionality Description

4600 space/spcmgmt Transaction Table 
4800 dict/rowcache Query Row Cache

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.

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
