This error message could mean errors in different areas of the Oracle kernel. The actual area is identified by the
arguments listed in the error message. For example

ORA-600: internal error code, arguments: [ 784 ], [ 0x3BE577248 ], [ 0x3BE578B88 ],

In the ORA-600 error message, the first argument 784 indicates that the error is related to the service layer.
Similarly, depending on the range that the first argument falls into, the error is grouped under a specific category, as
shown in Table 18-1 .

If an ORA-600 error is encountered and a solution to the problem is not available internally or from search on
metalink, Oracle Support needs to be notified by opening a service request. During the notification process, all related
information, including copies of the alert log and trace files referenced in the alert log, needs to be uploaded for
Oracle to analyze and provide the appropriate fix 2 .

■ as discussed in the earlier sections, starting with oracle Database 11g, the aDr should be used to package all
related information required for oracle support.
