Hi.
I'm trying to implement a DataGuard on Solaris 10 x64, but when I'm linking a physical standby database with the Primary database, always have the next error:

ORA-12533: TNS:illegal ADDRESS parameters
FAL[server, ARCh]: Error 12533 creating remote archivelog file '(DESCRIPTION=(ADDRESS_LIST=)(CONNECT_DATA=(SERVICE_NAME=dbb_XPT)(SERVER=dedicated)))'
FAL[server, ARCh]: FAL archive failed, see trace file.

Errors in file /data/oracle/product/admin/dbp/bdump/dbp_arch_4949.trc:
ORA-16055: FAL request rejected

PING[ARC0]: Heartbeat failed to connect to standby '(DESCRIPTION=(ADDRESS_LIST=)(CONNECT_DATA=(SERVICE_NAME=dbb_XPT)(SERVER=dedicated)))'. Error is 12533.

-----------------------
The tnsnames.ora of production server have:

DBP =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = prod server ip)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = dbp_XPT)
)
)


DBB =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = standby server ip)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = dbb_XPT)
)
)

Thanks for your help.
