hi,
I have changed the listener hostname....before changing the host name also tnsoping database server name works fine....
i am posting the tnsnames.ora of databse server
RBTT =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS=(PROTOCOL=TCP) (HOST=application server_name) (PORT = 1521))
(CONNECT_DATA =
(SERVER=DEDICATED)
(SERVICE_NAME = RBTT)
tnsnames.ora for application server
RBTT =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS=(PROTOCOL=TCP) (HOST=database server name) (PORT = 1521))
(CONNECT_DATA =
(SERVER=DEDICATED)
(SERVICE_NAME = RBTT)
is this is the right one..
and regarding this connectivity between two servers tnsnames.ora and listener.ora plays a vital role....should i have to make any changes in sqlnet.ora in both application server and database server...should i have to copy sqlnet.ora,listener.ora in application server...and what has to be set in both???
I have changed sqlnet.ora in database server in names.directory_path=tnsnames.ora
thanks in advance,
