Oracle 9i RAC建库过程报错：ORA-29807: specified operator does not exist
这是oracle bug，针对这个bug描述如下：
This is a known issue (bug 2925665). You can click on the "Ignore" button to continue.
Once DBCA has completed database creation, remember to run the 'prvtxml.plb' script. from
$ORACLE_HOME/rdbms/admin independently, as the user SYS. It is also advised to run the
'utlrp.sql' script. to ensure that there are no invalid objects in the database at this
time.
解决方法：
安装完成后，执行以下两个脚本后可解决：
SQL> conn / as sysdba
Connected.
SQL>@$ORACLE_HOME/rdbms/admin/prvtxml.plb
SQL>@$ORACLE_HOME/rdbms/admin/utlrp.sql
