很遗憾，没有拿到客户的相关TRACE文件。因此无法确认出现ORA-600错误时，具体引发错误的语句以及堆栈信息。根据MOS的查询结果，这个kssadd: null parent的相关错误，只有一个和JOB相关的，虽然确认影响版本为11.1.0.7，很符合当前问题的版本，但是报错并未发生在JOB进程或CJQ进程上。

而从这个报错信息的发生来看，这个错误的出现与ORA-16191错误直接相关。这个600错误的出现都是在ORA-16191大量产生后出现的，而随着ORA-16191错误的被最终解决，该错误也没有再次出现。基本上可以确定，ORA-16191是这个ORA-600[kssadd: null parent]错误产生的一个诱因。

最后简单说明一下ORA-16191错误，导致这个问题的原因是主库修改了SYS的密码，导致主库归档到本库时密码不正确。在11g的情况下，如果开启了SEC_CASE_SENSITIVE_LOGON参数，那么有时即使复制了密码文件到目标数据库，报错依旧。将SEC_CASE_SENSITIVE_LOGON置为false，可以避免这个错误。
