ODP.NET unable to connect [message #543503] Wed, 15 February 2012 01:32 Go to next message

I am trying to connect to an 11gR2 DB from a Windows Server 2008 R2 64 bit client with a 64bit client application. The 64bit client is the only one installed in the machine and ORACLE_HOME and TNS_ADMIN points to the correct paths. I use ODP.net4 so I installed it to use the oracle home as the client.

I am able to connect to the server with SQLPlus, using TNS (afis/***@AFISL), but when I attempt to connect with the client application, I get this error:
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor

The connection string I use is: "Data Source=AFISL;user id=afis;password=***;"

ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
 *Cause:  The listener received a request to establish a connection to a
 database or other service. The connect descriptor received by the listener
 specified a service name for a service (usually a database service)
 that either has not yet dynamically registered with the listener or has
 not been statically configured for the listener.  This may be a temporary
 condition such as after the listener has started, but before the database
 instance has registered with the listener.
 *Action:
  - Wait a moment and try to connect a second time.
  - Check which services are currently known by the listener by executing:
    lsnrctl services <listener name>
  - Check that the SERVICE_NAME parameter in the connect descriptor of the
    net service name used specifies a service known by the listener.
  - If an easy connect naming connect identifier was used, check that
    the service name specified is a service known by the listener.
  - Check for an event in the listener.log file.

Ask your DBA.

Regards
Michel

Hi Michel,

Thank you for the input, I did check all the issues listed in the error description, I think that somehow ODP.net4 isn't using TNS correctly, as I am able to connect using SQLplus, using the same TNS name, so I don't think the problem is on the listener side.

Kind regards,
Gustav

Gustav, there is inconsistency in your Oracle Net files. In listener.ora, you create a listener called LISTENER1, but then you define SID_LIST for a listener called LISTENER. This is possibly why you get the ora-12514.

Another inconsistency: you have defined a default_domain in sqlnet.ora, but you have not appended this to the TNS name defined in tnsnames.ora. Personally, I do not use default_domain because I think it causes confusion for no benefit. I would get rid of it.

Hi John,

Thank for for the advise, I renamed the SID listener to LISTENER and removed the default_domain, but the problem persists.

I also tried to connect via easyconnect Data Source=afis/***@//10.1.22.18/afisl.pencom.local and that also doesn't work. What I can't understand is that I can connect with SQLplus and sqldeveloper on both TNS and easyconnect

I can connect with SQLplus
In that case, you are not using those files. The inconsistency with the default_domain makes it impossible.

Quote:
Data Source=afis/***@//10.1.22.18/afisl.pencom.local

There is no port specified here. Does ODP.net4 have a default for this? It would need to be :1521.

[edit: sorry, I missed that you had removed thhe default domain. So OK, SQL*Plus should work with those files now]

I tried adding the port (set to default 1521), so Data Source=afis/***@//10.1.22.18:1521/afisl.pencom.local, but no change

So does the listener know about the service?

lsnrctl services listener1


[edit:
also,

lsnrctl status listener1
]

I renamed the listener from listener1 to listener to remove the inconsistency mentioned in the listeners.ora file

Your database instance is not registering with the listener, probably because of the config file inconsistencies.

In your database istance:

alter system set local_listener='(ADDRESS=(PROTOCOL=TCP)(HOST=10.1.22.18)(PORT=1521))';
alter system register;


then re-run the lsnrctl commands, and try again.

But next time you post you MUST format the output correctly with [code] tags, as I have done above. Please read our OraFAQ Forum Guide and How to use [code] tags and make your code easier to read
