Hello,

I am having trouble connecting to a local database using tnsnames. I can connect from a remote PC just fine. Here are my specs:

-- Oracle 10g R2 w/patchset 10.2.0.3
-- listener.ora:
MOWBLSNR =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = oracle2.rhsnet.org)(PORT = 1529))
)

SID_LIST_MOWBLSNR =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = mowb.rhsnet.org)
(ORACLE_HOME = /oraclebase/product/10.2.0)
(SID_NAME = mowb)
)
)

-- tnsnames.ora:
MOWB =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = oracle2.rhsnet.org)(PORT = 1529))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = mowb.rhsnet.org)
)
)

-- sqlnet.ora:
NAMES.DEFAULT_DOMAIN= rhsnet.org

NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)

Here is the output of tnsping:
oracle@oracle2:~> tnsping mowb

Used parameter files:

TNS-03505: Failed to resolve name

I know there is stuff on the net regarding this, but I cant find the answer to my problem.

Can anyone tell me why this isnt working?

Thanks

>NAMES.DEFAULT_DOMAIN= rhsnet.org
try
#NAMES.DEFAULT_DOMAIN= rhsnet.org
instead

I commented that out and it still does not work.

Here is the output of lsnrctl status MOWBLSNR:

I figured out the problem. The file /etc/tnsnames.ora existed, but was empty. Apparently Oracle looks there before it looks in $ORACLE_HOME/network/admin/tnsnames.ora. I deleted the file /etc/tnsnames.ora and tnsping works.
