When trying to export any user using system the below error appeared

Connected to: Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 – 64bit Production
With the Partitioning, Real Application Clusters, Automatic Storage Management, Oracle Label Security,

ORA-06512: at “SYS.KUPV$FT”, line 1020
ORA-47401: Realm violation for CREATE TABLE on SYSTEM.SYS_EXPORT_SCHEMA_07

The above error related because the system user is not allow to access data Dictionary files.

Run the below command
SQL>
BEGIN
DVSYS.DBMS_MACADM.ADD_AUTH_TO_REALM(
realm_name => ‘Oracle Data Dictionary’,
grantee => ‘SYSTEM’);
END;
/
PL/SQL procedure successfully completed.

Or you can use the GUI in Database vault and under Data Dictionray realms add the system user as participant.

Thank you  

connection to database cannot be established – DBCA

Posted on by Osama Mustafa in Database
Environment :-

Oracle Grid Infrastructure 11.2.0.4
Nodes # : 4
Operating system : Redhat 6.6

When trying to configure enterprise manager the following error appeared :-

Connection to the database cannot be established because the listener could be down. Please make sure that the service is registered with a listener and the listener is up.

The listener is up, VIP is working on all nodes without any issue when check dbca logs looking for more details i found this error :-

dbca trace in $ORACLE_BASE/cfgtoollogs/dbca.

ORA-1017: invalid username/password

Both was correct, because of this i recreate password file on all nodes and restart my operation it’s working without any issue this time.

Thanks
