bin/svrmgrl

connect Target_Database_Login as SYSDBA ;
exit

If you use the Recovery Catalog:
bin/rman target Target_Database_Login rcvcat
Recovery_Catalog_Login

bin/rman target Target_Database_Login nocatalog
If this fails, refer to the Oracle documentation for instructions on how to set up
the password file and any relevant parameters in the initORACLE_SID.ora
