I'm trying to setup data guard broker in my production instance. I have duplicated the primary database to standby database successfully. I've added primary database to data broker configuration and when I'm trying to add standby database following error is getting
DGMGRL> ADD DATABASE 'orcl_standby' AS CONNECT IDENTIFIER IS orcl_standby maintained as physical;
ERROR: ORA - 12154 : TNS: could not resolve the connect identifier specified
Tnsping from primary db to standby db and vice-versa is successful. I'm able to connect primary db from standby db using sqlplus sys/password@orcl as sysdba
but when trying to connect to standby db from primary db, error is getting like
ORA – 12154 : TNS: could not resolve the connect identifier specified.
Tried out all possible solutions.
Below is my tnsnames.ora file
ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.25.42)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
(SID = orcl)
(UR = A)
)
)
ORACLR_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
(CONNECT_DATA =
(SID = CLRExtProc)
(PRESENTATION = RO)
)
)
ORCL_STANDBY=
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.25.44)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl_standby)
(SID = orcl_standby)
(UR = A)
)
)
Any help will be appreciated

The part after
IDENTIFIER IS
must be a connection to the database. You should replace theorcl_standby
with something like'(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=tcp) (HOST=<server of the Standby>)(PORT=1521)))(CONNECT_DATA=(SID=<the SID of the Standby>)(SERVER=DEDICATED)))'
.
