Purpose

This note aims to provide a high level overview of the internal errors which may be encountered on the Oracle Server (sometimes referred to as the Oracle kernel). It is written to provide a guide to where a particular error may live and give some indication as to what the impact of the problem may be. Where a problem is reproducible and connected with a specific feature, you might obviously try not using the feature. If there is a consistent nature to the problem, it is good practice to ensure that the latest patchsets are in place and that you have taken reasonable measures to avoid known issues.

For repeatable issues which the ora-600 tool has not listed a likely cause , it is worth constructing a test case. Where this is possible, it greatly assists in the resolution time of any issue. It is important to remember that, in a many instances , the Server is very flexible and a workaround can very often be achieved.

Scope and Application

This bulletin provides Oracle DBAs with an overview of internal database errors.

Disclaimer:Every effort has been made to provide a reasonable degree of accuracy in what has been stated. Please consider that the details provided only serve to provide an indication of functionality and, in some cases, may not be wholly correct.

ORA-600 Lookup Error Categories

In the Oracle Server source, there are two types of ora-600 error :

  • the first parameter is a number which reflects the source component or layer the error is connected with; or
  • the first parameter is a mnemonic which indicates the source module where the error originated. This type of internal error is now used in preference to an internal error number.

Both types of error may be possible in the Oracle server.

Internal Errors Categorised by number range

The following table provides an indication of internal error codes used in the Oracle server. Thus, if ora-600[X] is encountered, it is possible to glean some high level background information : the error in generated in the Y layer which indicates that there may be a problem with Z.

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 :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.

Ora-600 Base Functionality Description
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

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.

Ora-600 Base Functionality Description
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.

Ora-600 Base Functionality Description
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

Ora-600 Base Functionality Description
12200 progint/kpo
