EMCA fails with error "ORA-01017: invalid username/password; logon denied"

Creation of dbcontrol repository fails when execute

 

$ emca -config dbcontrol -repos create

With error:

Database connection through listener failed. Fix the error and run EM Configuration Assistant again.

Some of the possible reasons may be:

1) Listener port 1521 provided is incorrect. Provide the correct port.
2) Listener is not up. Start the Listener.
3) Database service is not registered with listener. Register the database service.
4) Listener is up on physical host and ORACLE_HOSTNAME environment variable is set to virtual host. Unset ORACLE_HOSTNAME environment variable.
5) Listener is up on virtual host. Set environment variable ORACLE_HOSTNAME=.
6) /etc/hosts does not have correct entry for hostname.

Cause

SYS password is invalid.

Solution

1) drop existing dbcontrol
  $ emca -deconfig dbcontrol db -repos drop
2) reset SYS password (also in password file, if using)
3) create the dbcontrol
  $ emca -config dbcontrol -repos create

尝试上述步骤无效后，发现remote_login_passwordfile参数在之前的测试中被修改了，改回后终于成功
