Q

"Invalid column name" error

I am running a command to create a backup file on an Oracle 8i database running on a Netware 5 server. I receive an "invalid column name" error message. What do I need to do to find out what the column name is that is causing the error?

I am running the following command to create a backup file on an Oracle 8i database running on a Netware 5 server:
 
exp81 system/manager full=y file=User:orahome1hris_backup.dmp 
log=User:orahome1hris_backup.log
I receive the following error message: "exporting referential integrity constraints. exporting synonyms"
 
EXP-00008: ORACLE error 904 encountered
ORA-00904: invalid column name
EXP-00000: Export terminated unsuccessfully
What do I need to do to find out what the column name is that is causing the error?
It looks like the Data Dictionary is not correct. Sign on to the database with SQL*Plus as the SYS user and run the catexp.sql script found in your ORACLE_HOME/rdbms/admin directory. That should fix the problem.
