OK (0 msec)
When I connect to standby database using SQL getting the error.
SQL> connect sys/password@orastd as sysdba
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor.
Solution:
Looks like your standby DB instance is not register with the listener.
You have to register db using NETMGR or edit listener.ora file.
