ORA-00600: internal error code, arguments: [12235], [], [], [], [], [], [], []

一个客户的数据库时发现有ora-00600 12235错误，并且出现频率不高
客户数据库版本9.2.0.7 操作系统AIX 5.3Mon Dec 22 12:01:15 2008Errors in file /software/oracle/admin/sjqddb/bdump/sjqddb_ora_5644398.trc:ORA-00600: internal error code, arguments: [12235], [], [], [], [], [], [], []解决该问题的方法:以下metalink解释Note: For additional ORA-600 related information please read Note 146580.1PURPOSE: This article discusses the internal error "ORA-600 [12235]", what it means and possible actions. The information here is only applicable to the versions listed and is provided only for guidance.ERROR: ORA-600 [12235] [a] [c] [d] [e]VERSIONS:versions 7.0 to 9.2DESCRIPTION: This error shows up when Oracle detects an Oracle defunct process.When an Oracle process starts up, it reads data from the SGA that defineswhat type of process it should become.If the process does not locate any valid customization data, it reports ORA-600 [12235] and exits.On a heavily loaded system, ORA-600 [12235] may be a symptom that the server process was too slow in starting. That is, the process that initiated the new server may timeout waiting for the new process to start and abandon the new server request. In the new server process it is possible that the new server reaches the code to customize its operation before the os request to kill the process is actioned. The messages "ksbsrv: No startup acknowledgement from forked process ..." and "Timed out trying to start shared server ..." may be reported to trace and alert files.FUNCTIONALITY:USER/ORACLE INTERFACE LAYERIMPACT:NO IMPACTSUGGESTIONS:Ignore the error.One of the most common reasons for this error to be reported is that someone typed 'oracle' manually at the OS prompt.If this error is reported regularly and appears not to be explainedby comments made in this note, contact Oracle Support Services.Known Issues:Bug# 3616023 P See Note 3616023.8Tru64: "skgpspawn failed:category = 27143" during process / instance startupFixed: 10.2.0.1Bug# 405159 See Note 405159.8OERI:12235 possible starting any slave processFixed: 8.0.6.0通看metalink解释说是人为的运行了oracle命令也有可能造成该bug出现,对生产系统没什么影响，可以忽略。
