ORA-29807: specified operator does not exist


这是Oracle 的bug , 可以忽略掉，安装完成后，在$ORACLE_HOME/rdbms/admin 目录下运
行utlrp.sql ，用于修补ORA-29807 错误。
解释：
ORA-29807: specified operator does not exist
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.
 
$ dbca
Fatal: Stack size too small. Use 'ulimit -s' to increase default stack size.
