$ $ORACLE_HOME/bin/sqlplus "sys/password as sysdba"

SQL> alter user dcm identified by hello1234 account unlock;

Special Note:

The instance is different from other Oracle Application Server instances. During the installation of OracleAS Metadata Repository Installer does not ask for AS instance name and once the installations is finished, OEM 10gAS Server control is not started up, because it is not configured for this instance. As this instalaltion steps only install the metadata which is not required to manage.
