I have a 2 node RAC but failed to create EM dbcontrol. Error "Password for SYS user: Invalid username/password"

[Woody Ling]

I have a 2 node RAC and used the following command to create the EM
dbcontrol :

emca -config dbcontrol db -cluster

STARTED EMCA at 10-may-2008 17:33:42

Enter the following information:
Database unique name: abcdb
Listener port number: 1541
Cluster name: crs
Password for SYS user:
Password for SYS user: Invalid username/password.
Password for SYS user:
Password for SYS user: Invalid username/password.
Password for SYS user:
Password for SYS user: Invalid username/password.
Password for SYS user:
Password for SYS user: Invalid username/password.
Password for SYS user:
Password for SYS user: Invalid username/password.
Password for SYS user:

The password is ok, I can connect by "sqlplus sys/password@abcdb as
sysdba" with no problem. But emca does not work.

In order to test the password, I try "emca -config dbcontrol db" and
no error. However, only one node em is created.

The crs is ok, listeners are up, tnsping response ok.

I also drop and re-create the db by dbca but it has the same problem.

I have tested "reconfig dbcontrol, -repos create, -repos drop etc" but
still same error...

Any idea?
