Export Missing table on 11GR2 ?

Question

I'm observing this mystery on our 11.2.0.1.0 system running under Solaris about mysterious missing tables that really exist on the database.
Here is the log of my session trying to export an existing table and export cant seem to find it .
-bash-3.00$ . oraenv
ORACLE_SID = [oracle] ? HR90
The Oracle base for ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome01 is /u01/app/oracle
-bash-3.00$ sqlplus system

About to export specified tables via Conventional Path ...
EXP-00011: SYSADM.PSCLASSDEL does not exist

Even a full export of the schema does not include these "missing" table at all.
Has anyone encounteed this on 11gR2
Thanks.

Answer 1

Thanks . This seems to be a new parameter in 11gR2 . It just got me by surprise that Oracle set it to true by default changing the old behaviour . Inserting records is really not an option but there are modules in the system that does check these table's existence after an import restore. I'm going to be using expdp to get these tabs back. Anyway all seems well . Thanks to all who responded.Have a great day .
