Hi all.
Oracle 8.1.6.0.0 EE , NT4.0 SP6
=======================
SQL> desc OLD_EBCREDT
Name Null? Type
----------------------------------------- -------- ----------------------------
F1 NUMBER(10)

SQL> drop table OLD_EBCREDT ;
drop table OLD_EBCREDT
*
ERROR at line 1:
ORA-00604: error occurred at recursive SQL level 1
ORA-01410: invalid ROWID

SQL> drop trigger EBCREDU;
drop trigger EBCREDU
*
ERROR at line 1:
ORA-00604: error occurred at recursive SQL level 1
ORA-00607: Internal error occurred while making a change to a data block
ORA-00600: internal error code, arguments: [kcoapl_blkchk], [1], [105952],
[6401], [], [], [], []

What is problem ? Is error in data dictinary ?
Is sys tables corrupted(triggers$ or objects$ ,.. )?
ORA-00607 not exists in Oracle Error Message. Why?
I am wait for reply.

Best Regards.
