I have just installed TOra 2.0 as I am hoping it will be a decent replacement for SQLDeveloper, but I cannot connect to any Oracle Databases.
I am running XP SP2. I installed TOra using tora-2.0-setup.exe
I have Oracle 10g Client installed (I have been unsing this for ages so I know this is working) and also I have installed (unpacked) the 11g Instant Client into to TOra directory, and setup my PATH as in the Instant Client Documentation.
When I try to connect to a database using the Oracle (Instant Client) connector I get the following message.
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
I am pretty sure the connection details are correct, as I use them with SQLDeveloper. I am assuming that in the connection details where it asks for database this is the Oracle SID. Is this correct?
I do not have an option the use the Oracle TNS connector..should I have one?
Can anyone help me fix this?
I have a similar problem. I'm using the TOra-2.0-windows.zip package.
The connection works using Oracle SQLplus command line but not using TOra.
Can anyone help with that?
Yes I have the same problem. Please help...
Please use the 10.2 instant client with the Windows build, they are not major-version compatible.
Try the SERVICE_NAME value from tnsnames... Let me know if that works.
Er, sorry. Too fast on the submit button. You don't have a tns provider listed probably because you don't have ORACLE_HOME defined. You wouldn't want to use it anyhow.
Took me a while to get this too...
First, download Version 10.2.0.4 "Instant Client Package - Basic: All files required to run OCI, OCCI, and JDBC-OCI applications". (Lite version may work too)
Here's a link although it might eventually stop working:
Second, extract (or drag) the DLL files form the client to "C:\Program Files\TOra\"
Third, set up your client as follows:
Connection Provider: Oracle (Instant Client)
Host: 10.1.1.1 (The ip or hostname of the server)
Schema: (leave blank for now)
Port: (leave at 1521)
Database: (get this from the SID = XXX value in your ORACLE_HOME, sometimes "c:\orant\NET80\ADMIN\") You can probably guess this value easily.
This should save some people a couple hours!
I tried the above but I get the error
Unable to connect to the database
ORA-12514 TNS:listener does not currently know of service requested in connect descriptor
Can you help me out? Can I not somehow connect using the tnsnames file?
Thanks in advance.
I also want to add that in my case Oracle gives error 12514 if I do not specify database.
It took me about five annoying hours to figure out how to come around the 12514 message. I tried out several combinations of setting env-variables, installing instant-clients, tora-versions, exchanging dlls all to no success.
Finally the following worked for me on XP with tora 2.0, trying to connect against a remote oracle 11 db (I do not know whether all steps are really necessary):
- DL instant client 10.2.0.4, extract to somepath\ -
- create somepath\network\admin
- add tnsnames.ora with the values you get from you dba.
mine looks like:
(ADDRESS = (PROTOCOL = TCP)(HOST = dbhost)(PORT = dbhostport))
(SID = dbsid)
(SERVER = DEDICATED)
- Add ORACLE_HOME = somepath\ as a env-var (e.g. as a user-variable)
- Add TNS_ADMIN = somepath\ (not so sure whether neccesary)
- Add sometpath\ to your path
- Eventually add NLS_LANG as system-variable. See oracle documentation for details. Assumingly this one is neither needed.
(e.g. NLS_LANG = GERMAN_GERMANY.WE8MSWIN1252)
- Reboot (chaka!)
- Install Tora 2.0 and run it
- Now you should be able to choose Oracle(TNS) as for connection provider and all DB_Aliases should be displayed under the database drop down.
- Choose your db, fill in username and pw information and hopefully connect succesfully to your db.
Hope this helps.
No need to create the directory somepath\network\admin
just insert the tnsnames.ora into the somepath\ directory
steinhoe is right!
Add ORACLE_HOME to user variables and set the path to the oracle (instant) client directory. In my case it was:
(no need for instant client if you have oracle client)
Windows XP SP3, Tora 2, Oracle client 10.2.0.
