I have client and database on same machine, when I will connect to the instance , it will use IPC, suppose If I will use connection string then which process will handle this request?
View 2 RepliesI have one query related to database connection from server to client.I have one database in the server and I want to connect from client.I set the tnsnames in client system as follows.

The database name is : BAM_240T.ipdc.com
Sqlnet.ora entry is

When I connect to server I m getting the following error.

I am having difficulty in making the 32 bit Oracle client connection to an existing 64 bit DB. The 64 bit SQL*Plus will connect just fine, but when trying to configure the 32 bit client I can never get a successful TEST of the connection. It always returns "No TNS Listener". I have tried several things, but may be way off base. To name a couple ...
1) Stopped the 64 bit listener so my 32 bit listener can use Port 1521 ... no success
2) Tried naming the 32 bit listener to LISTENER32 to not conflict with the original LISTENER name ... no success
If there is a documented way to make this work, I would surely like to be pointed to the "how to" of this item. I need this as a commercial application I have that connects to the DB requires the 32 bit client.
When i connect from client to server the client looks up for the host address and port number in tnsnames.ora and connect to it via listener.ora in server.Where does pga and sga come into picture here?
Also what is the role of sqlnet.ora in client?What will happen if i specify a different port for the instance in tnsnames.ora and listener.ora?
connecting two oracle database in two different server.I installed Oracle 10g XE in both system.Both system act as Server.I need to connect both server using database link concept.

Connecting Oracle to SQL Server via database link.
I am trying to connect from Oracle 10G to a SQL Server database. I have looked at the manual and i will admit that i am finding the documentation quite difficult to follow. There seems to be several options to use but none of the documentation describe how each option works.
As an example, i have been given the following information on the database i need to connect to (i.e. the SQL Server database)
- Username
- Password
- Database Name [lets assume the database name is data_extract]
To connect the above i made the following changes
$ORACLE_HOME/hs/admin/inithsodbc.ora
---------------------------------------
HS_FDS_CONNECT_INFO = data_extract
HS_FDS_TRACE_LEVEL = 0
$ORACLE_HOME/network/admin/tnsnames.ora

sqlserver.db =
(DESCRIPTION =

Note: In listener.ora, i only added the last SID_DESC entry. I then went on and created the database link as shown below
create database link sqlservdb using 'sqlserver.db';
When i try to access a table i get the following error
sqlplus> select * from TESTTABLE@sqlservdb;
select * from TESTTABLE@sqlservdb

ERROR at line 1:
ORA-28545: error diagnosed by Net8 when connecting to an agent

ORA-02063: preceding 2 lines from ORASQLSERVER
A couple of things i am not sure of:
- Where do i specify the username and password to access the sql server from the oracle db to the sql server db
- Having read around on the internet, i can see some people refering to a DSN datasource. I am told that the information that i have is all i need. Is this correct or do i need something else?
- The sid i specified in inithsodbc.ora and tnsnames.ora is actually the sql server database. Is this correct?

I have been told client is not getting to the listener because listener is only listening on 127.0.0.1.
unless & until DB server is configured with a routable IP#, no remote client will succeed.
Database is up and running and client machines able to do TNSPING; But when users try to connect the database thro SQL DEVELOPER, they are getting below information:
your database connection has been reset. Any pending transactions or session state has been lost.in the database server, SQLNET.ORA reads as below:
> more sqlnet.ora
AUTOMATIC_IPC = ON
names.directory_path = (TNSNAMES,EZCONNECT)
names.default_domain = world
name.default_zone = world
sqlnet.expire_time = 15sqlnet expire time shows 15 min.
normally this error willbe suppressed if user tried after some time. But now we get this error for more than 2 hrs.
1) I put attention that TNS write events into its log in too big frequency: ~ 10 time in second. I see that it is for every connection, but I assume that this no too good to performance.Is there some way to tell to TNS not to write event for every connection but only for errors?
2) May I to remove alert.log of DB? Or DB will make me problems with this?
3) How can I tell to my client connect directly to my instance rather than during TNS?

I installed Oracle Express on my Windows 2003 Enterprise server. And right off the bat I cannot connect to it via command line. I have googled and read many sites, but am still getting the same error, no matter what I do. I am newbie again (was a DBA in 1990...when I used to have the same error and fix it in seconds...not sure why this problem still lingers in Oracle) so most likely I am overlooking something. Below are my tnsnames.ora and liserner.ora files

I am trying to create a database link using this syntax:
CREATE PUBLIC DATABASE LINK remote
USING 'remote';
where 'remote' is the service name. It creates it successfully giving the message "External database Created"
Note: I am doing using TOAD

select * from scott.employee@remote
it gives an error:
ORA-12154: TNS:could not resolve the connect identifier specified
But the 'remote' db entry exists in the tnsnames.
Can currently connect to a 9.2.0.1 database using Oracle Developer 6.0 with the following connect string:
C:orantBINifrun60.EXE GMS ops$cannonc/cannonc@GMS3B.TEST.COM[/email]
I don't believe it is using the TNSNAMES.ora entry for this, because when I take it out of there it still connects. I create a 10.1.0.5 database and copied the tables,etc to there. But I'm having problem connecting, getting "ORA-12154:TNS Could not resolve service name". Tried the following:
C:orantBINifrun60.EXE GMS ops$cannonc/cannonc@NJZTEST[/email]
C:orantBINifrun60.EXE GMS ops$cannonc/cannonc@NJZTEST.TEST.COM[/email]
I did add the entry for the 10G database to TNSNAMES.ora:
NJZTEST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = njzainettest.test.com)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = njztest)
)
)
I new to this, but my guess is the other entry had the full path name..and this SERVICE_NAME does not. But then again I don't believe it looks at the TNSNAMES file. This NJZTEST is the 2nd instance on the NJZAINETTEST machine.
