I have a 9.2.0.7 Oracle database on MS Server 2003. I am getting the
error above on anything I try to do. This is a newly created database.
Also was able to import data from another database to it. Now
everything gets this error. On Metalink it states to run the utlrp.sql
script as sys. This did not correct the problem. I can query v$lock
without getting an error, and I do not see a lock on the system. If I
try to look at v$session I get

ERROR at line 1:

ORA-04020 (See ORA-04020.ora-code.com): deadlock detected while trying to lock object

SYS.CDC_ALTER_CTABLE_BEFORE

Has anyone had a problem like this and was able to resolve it.

Thanks in advance,

Laura
