Hello All,

I am trying to configure physical standby(s) across two boxes. I am getting the errors

ORA-12154: TNS:could not resolve service name
ORA-16055: FAL request rejected

I am able to communicate between the two servers, tnsping both of them, sqlplus to each of the instances, but getting the TNS issue. Can you please point me to something which i am missing.

Please let me know if you would need more details.

Please find the alert log details:

>ORA-12154: TNS:could not resolve service name
ERROR means that the connect string could not be resolved (on local node).
Typically it means the @TNS_ALIAS could not be found in local tnsnames.ora file
