How Oracle Error 1033 occurs and ORA-00600 errors are resolved

This error frequently occurs in Oracle data after an illegal shutdown:

Exp-00056:oracle Error 1033 appears

Ora-01033:oracle initialization or shutdown in progress

User:

Password:

This is obviously the database does not have the means to start, but the database service can be started, but the program cannot connect to the database.

The first choice to find the problem to see the database bdump directory alert file specific report what the error

You see the last few rows

Errors ORA-00600: Internal error code, parameters: [Kcratr1_lostwrt], [], [], [], [], [], [], []

This error does not need to study what meaning, the following is the solution:

oracle9/10g startup times wrong ORA-00600: Internal error code, parameters: [Kcratr1_lostwrt], [], [], [], [], [], [], []

By the way, the role of Oracle's several adump, Bdump, Cdump, Dpdump, Pfile, and Udump directories:

Audit_file_dest = C:\ORACLE\PRODUCT\10.2.0\ADMIN\ORCL\ADUMP

Background_dump_dest = C:\ORACLE\PRODUCT\10.2.0\ADMIN\ORCL\BDUMP

User_dump_dest = C:\ORACLE\PRODUCT\10.2.0\ADMIN\ORCL\UDUMP

Core_dump_dest = C:\ORACLE\PRODUCT\10.2.0\ADMIN\ORCL\CDUMP

From the above you can know:

Adump: Audit Information

Bdump: Background process trace and alert log, which means that Alert_sid.log also exists in this directory

Cdump:core trace, typically used to log applications, will have little information unless there is a problem with the database.

Dpdump: is to store some login information

Pfile: initialization parameter file Initsid

Udump: Foreground manual trace, such as the trace file for session after SQL Trace

There are alert files in the Bdump, and some background process trace file

Trace file for session after SQL Trace is normally placed in Udump

Cdump typically place some core trace files

Wangfl

Adump is generally audit dump

Bdump is background dump.

Udump is User dump

Cdump is core dump
