do (for example, “ORA-00942: table or view does not exist”), it is difficult to assess the seriousness of the error and whether it is cause for concern. This column explains what you can do to assess some ORA-600 or ORA-7445 errors and identify solutions. ORA-600 or ORA-7445: What Is the Difference? ORA-600 is a catchall message that indicates an error internal to the database code. The key point to note about an ORA-600 error is ora-00600 internal error code arguments kcratr_nab_less_than_odr that it is signaled when a code check fails within the database. At points throughout the code, Oracle Database performs checks to confirm that the information being used in internal processing is healthy, that the variables being used are within a valid range, that changes are being made to a consistent structure, and that a change won’t put a structure into an unstable state. If a check fails, Oracle Database signals an ORA-600 error and, if necessary, terminates the operation to protect the health of the database. The first argument to the ORA-600 error message indicates the location in the code where the check is performed; in the example above, that is ktfbtgex-7 (which indicates that the error occurred at a particular point during tablespace handling). The subsequent arguments have different meanings, depending on the particular check. An ORA-7445 error, on the other hand, traps a notification the operating system has sent to a process and returns that notification to the user. Unlike the ORA-600 error, the ORA-7445 error is an unexpected failure rather than a handled failure. The Oracle function in which that notification signal is received is usually, from Oracle Database 10g onward, contained in the ORA-7445 error message itself. For example, in the error message ORA-07445: exception encountered: core dump [kocgor()+96] [SIGSEGV] [ADDR:0xF000000104] [PC:0x861B7EC] [Address not mapped to object] []

ORA-00600: internal error code, arguments string tips Oracle Error Tips by ora 600 lookup tool on metalink Stephanie F. The Oracle docs note this on the ORA-00600 error: Error: ORA 00600 Text: internal error code, arguments: [%s], [%s], [%s], [%s], [%s], [%s], [%s] ------------------------------------------------------------------------------- http://www.oracle.com/technetwork/issue-archive/2011/11-sep/o51support-453463.html Cause: This is the generic internal error number for Oracle program exceptions. This indicates that a process has encountered an exceptional condition. Action: Report as a bug - the first argument is the internal error number On the Oracle DBA Forums, a user needs help with ORA-00600, as well as understanding the accompanying arguments. The replier informed the http://www.dba-oracle.com/t_ora_00600_internal_error_code_arguments_string_%20string_string_string_string_string_string.htm user that because ORA-00600 is an internal error, the Oracle Corporation knows the arguments. Here are the notes which helped the user resolve ORA-00600: An ORA-00600 is an internal error, and only Oracle Corporation knows the agruments. ALWAYS open a TAR when you get a ora-600. I check MOSC, and you can see many of the "common" codes there. ****************************************** ORA-00600 internal error code, arguments: [string], [string], [string], [string], [string], [string], [string], [string] Cause: This is the generic internal error number for Oracle program exceptions. It indicates that a process has encountered a low-level, unexpected condition. Causes of this message include: timeouts file corruption failed data checks in memory hardware, memory, or I/O errors incorrectly restored files The first argument is the internal message number. Other arguments are various numbers, names, and character strings. The numbers may change meanings between different versions of Oracle. Action: Report this error to Oracle Support Services after gathering the following information: events that led up to the error the operations that were attempted that led to
the generic kernel code of the Oracle RDBMS software. It is different from other Oracle errors in many ways. The following is a list of these differences: 1. An ORA-600 error http://www.orafaq.com/wiki/ORA-00600 may or may not be displayed on the screen. Therefore, screen output should https://oracle-base.com/articles/misc/ora-00600-ora-07445-ora-00700-how-to-diagnose-and-fix-them not be relied on for capturing information on this error. Information on ORA-600 errors are found in the database alert and trace files. We recommend that you check these files frequently for database errors. (See the Alert and Trace Files section for more information.) 2. Each ORA-600 error comes with a list of arguments They usually internal error enclosed in square brackets and follow the error on the same line for example: 3. Also some time, if we have used many cte's in a SP then it throws same error because of memory used by these ctc's exceed. ORA-00600 [14000][51202][1][51200][][] Each argument has a specific meaning which can only be interpreted by an Oracle support analyst. The arguments may also change meaning from version to version therefore customers internal error code are not advised to memorize them. 4. Every occurrence of an ORA-600 should be reported to Oracle Support. Unlike other errors, you can not find help text for these errors. Only Oracle technical support should diagnose and take actions to prevent or resolve damage to the database. 5. Each ORA-600 error generates a database trace file. Possible causes[edit] Possible causes include: time-outs, file corruption, failed data checks in memory, hardware, memory, or I/O messages, incorrectly restored files a SELECT FROM DUAL statement in PL/SQL within Oracle Forms (you have to use SELECT FROM SYS.DUAL instead!) How to fix it[edit] Contact Oracle Support with the following information: events that led up to the error the operations that were attempted that led to the error the conditions of the operating system and database at the time of the error any unusual circumstances that occurred prior to receiving the ORA-00600 message. contents of any trace files generated by the error the relevant portions of the Alert file in Oracle Forms PL/SQL, use SELECT FROM SYS.DUAL to access the system "dual" table Sometimes gathering statistics on the involved tables resolves the problem. Deleting statistics for a table involved would also solve the problem Try to reduce the no of CTE block

Introduction ORA-600/ORA-7445/ORA-700 Error Look-up Tool Introduction Oracle trap errors and gives them a specific error number. Looking up this error number in the Database Error Messages manual will typically give you an indication of the cause of the error and the action necessary to fix it. In addition to trapping specific errors, Oracle also has some catch-all error messages that are issued when something unexpected happens, the most important being the following. ORA-00600: internal error code, arguments: [string], [string], [string], [string], [string], [string], [string], [string], [string], [string], [string], [string] ORA-07445: exception encountered: core dump [string] [string] [string] [string] [string] [string] ORA-00700: soft internal error, arguments: [string], [string], [string], [string], [string], [string], [string], [string], [string], [string], [string], [string] These may be caused by something trivial, but they could also indicate something disastrously wrong has happened. It's impossible to tell by just looking at the error message and the description in the Database Error Messages manual. This article explains what you should do if you encounter one of these types of messages. ORA-600/ORA-7445/ORA-700 Error Look-up Tool You should typically use the following process. Log on to My Oracle Support. Go to the ORA-600/ORA-7445/ORA-700 Error Look-up Tool. Select the type of error (ORA-600/ORA-7445/ORA-700), enter the value of the first argument (the value within the first set of square brackets [?????]) and select the database version from the dropdown list. Click the "Lookup Error" button. Read the popup message and take the appropriate action. The popup will contain one of two types of messages. If the issue has been encountered before, the popup wi
