TNS Listener Throwing ORA-12514?
Mar 29, 2011
Our Oracle database was working fine up until last Thursday, now, for reasons unknown, Oracle is refusing connections. I have done a lot of reading about this error and I have performed all of the recommended actions to no avail. The actions I have performed are (see [URL])...
- Wait a moment and try to connect a second time. Yes, did that, probably 1,000 times - same results.
- Check which services are currently known by the listener by executing: lsnrctl services <listener name> And here are those results (I replaced some of the private stuff with x's)...
C:\Documents and Settings\xxxxx.xxxxx>lsnrctl services orcl

Services Summary...
[code]...
Why does the service PLSExtProc show up but not orcl? I don't get this but that's how its been since installation and as I said, it worked fine until last Thursday.
Here is what my TNSNAMES file looks like (again, replaced private info)...
# tnsnames.ora Network Configuration File: \oracle\product\10.2.0\db_1\NETWORK\ADMIN\tnsnames.ora
# Generated by Oracle configuration tools.
ORCL =

[code]...
- Check that the SERVICE_NAME parameter in the connect descriptor of the net service name used specifies a service known by the listener. See above.
- If an easy connect naming connect identifier was used, check that the service name specified is a service known by the listener. I don't know what this is.
- Check for an event in the listener.log file. There are a ton of them ... here is one of the entries...

One of colleague (who has left) created a database link using the statement:
CREATE PUBLIC DATABASE LINK CIVCLMANLINK USING ''CIVCLMAN''
When I try to use this link like:
SELECT * FROM CLIENTMANAGEMENT.ADDRESS@CIVCLMANLINK;
I get the following error:
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
I can connect to the CIVCLMAN using the Oracle Enterprise Manager / SQL Plus, I can tnsping as well

I searched the knowledge base here and in other forums and haven't found the answer. There was a similar condition presented earlier, but it turned out the resolution was to run the >shutdown/>startup on the server rather than from a client. Not applicable in my case!
Shutdown and startup called used to work with 9i, now startup fails in 10g. ORACLE_HOME and ORACLE_SID are set and report correct values. What is different in 10g that the script (shown below) now throws a TNS listener error after shutdown?
I successfully upgraded from 9i to 10g (10.2.0.5.0) on Windows Server 2003, 32-bit last weekend. Now our backup_script.bat and oracle_stop_start.sql throw "ORA-12514: TNS:listener does not currently know of service requested in the connect descriptor"
This batch file and sql script predate me and worked with 9i for years. Now the startup command in the oracle_stop_start throws this error after executing shutdown. The backup batch file calls:
sqlplus "system/manager@wind as sysdba" @D:ptcwindchillackupsoracle_stop_start
The entire oracle_stop_start.sql is as follows:
shutdown immediate;
startup open;
quit
What is different in 10g that this now doesn't work? Shutdown works, but it will not startup due to the listener error. I have made the backups work by commenting out the call to sqlplus and I'm getting good backup dumps.
In my virtual image of the server I have found that I can duplicate the error after >shutdown. I have found that if I exit sql*plus and go back in as follows I can get the database instance to restart from the command line:
c:>sqlplus /nolog
sql>connect sys/* as sysdba
sql>startup open wind;
That does start, mount and open the database instance.
Is there a better way to be making sure that everything is stopped before executing the >exp command to create a backup dump? I will look into and test datapump export/import and RMAN for creating the backups, after I get this working again.
why this worked in sql*plus in 9i but not in 10g? Can I make TNS Listener smarter? Change or add variables to the startup command?

I'd like to call an existing function/procedure from a resource template. For example, I have a procedure called 'rest' with an out parameter of 'p_out' - how do I use this within a resource template?
At the moment I have defined the template as type 'PL/SQL Block' and with the 'GET' defined as:
begin
myschema.rest(:p_out);
end;
APEX_PUBLIC_USER has been granted 'all' on the procedure. The p_out is populated with a piece of text.
When I call this resource, I get a '500 Internal Error' returned. I've tried adding p_out as an X-APEX-FORWARD parameter, but nothing seems to work.
Query-based templates seem to work OK.
Using Listener 1.1.3 with Tomcat6.

I am using oracle 11.2.0 in linux platform.i have created a listener for the asm database. and i am using non default port of 1525 whenever i go for lsnrctl>status always shows for the port 1521. i don't want the default port 1521 and i have changed the local listener as listener1 with port 1525 protool tcp in spfile and registered with the asm database.Is there any option to change the default listener as listener1.
also,everytime when i give lsnrctl>show current_listener it is showing "listener"
i have set the current-listener to listener1 and save_config listener1 and reloaded.After exit and enter lsnrctl>status it will show for port 1521 When i attempt to start listener1 every time. it will prompt listener1 is already running.

In one of our RAC envrionment, we have more than 15 databases in a server running in AIX Operating system.the Listener file I am able to find only one entry (SID). But while trying to execute lsnrctl status it displays all the 15 SIDs in the list hosted in the ser ver. Not sure how it works?
As we created another one new database in the database, where i need to add this SID in the listener.ora file to reload the listener.

We have many many APEX applications in APEX 3.0 running on a 10.2.0.4 database that needs desperately to be upgraded. As a test, I've set up a clean 11gR2 database and copied the production APEX database into it via datapump. I set up APEX Listener, as I don't have any OAS sitting around and the EPG doesn't seem to be supported for APEX 3.0... the Listener doesn't say one way or the other.
When trying to log in, I get the login page, but it tries to reference files such as apex_get_3_1.js while I only have files such as htmldb_get.js in my images directory in production. I noticed it is looking for what appears to be 3.1 files instead of 3.0 files... which concerns me.
The APEX listener appears to be more than just a Java PL/SQL gateway.
Is there a minimum version of APEX the APEX Listener supports?

We have a listener with the password set to it. We are trying to configure that listener to the OEM grid. However, its not getting configured. The status shows as down.
However, when we try to set up without the password, we are able to configure it on the OEM console.
Need to understand, that if passwords are set to the listener; then won't that get configured over the OEM. or is there something where we are lacking.

I am new to Oracle DB. I have installed Oracle 10g in XP Service Pack2 and was able to login using SYS/SYSTEM users and also was able to create a new user XYZ...
Once I restarted my system, I am facing a strange problem while login. It is continuously throwing the error "tns: listener does not currently know of service requested in connect descriptor". I do not understand the reason. I have checked the services and all oracle related services are running.
However, when I tried to login with the same userid/password from command prompt using 'sqlplus' command, I am able to login ! There was no error this time.

i have installed oracle 11g r2 rac with 2 nodes. i want to configure the client side load balancing and server side load balancing. For the client side load balancing the i have configured with the
(FAILOVER=ON) (CONNECT_TIMEOUT=5) (RETRY_COUNT =3).
and to configure server side load balancing i have modified the service as follows:
execute (DBMS_SERVICE.MODIFY_SERVICE (service_name=>'service_name', clb_goal=>DBMS_SERVICE.CLB_GOAL_SHORT);
now i have few questions:
1. for the server side load balancing do we have to configure the REMOTE_LISTENER on each node so that the instance on each node registers with the listeners on other node.
2. if we have 3 nodes does this mean that we have to configure the REMOTE_LISTENER on 3 nodes to register with the listeners on the other remaining 2 nodes.
3. does the listener have to be registered with the vip network address (where the clients usually use to connect).

how setting up Forms6i to work with 10g database? Do I need some Patch? What special configuration to make? What about the many TNSNAMES.ORA and SQLNET.ORA files in the Forms 6i Folder, versus those on the 10g Database Folder?

I have local development Oracle 9i database in my Windows XP. I see it uses TNS Listener port 1521. For some reason it must be using port 8080 also or in the background because it seems to not let my local web container (Apache Tomcat which uses Port 8080) on the same workstation work when it (TNS Listener) is turned on. how I edit the Listener port number and if I do change the port number what other things do I need to change such as the OEM login settings to the local database

11g RAC environment, I manually shutdown the database with "shutdown immediate" and stop the listener with "lsnrctl stop". Later I manually startup only the database but the listener is also started automatically at almost the same.
Why would this happen ? I just don't want the listener to startup automatically at that time. What can i do to prevent the listener from auto-starting when i startup the database manually.

From doc. I see that the "current" is the number of client connections it is handling, that is, its current load.It is not correlating with the sessions or processes in DB, so what does this means?
Does it show that more than 150 connections try to perform connection simultaneously?

I've been trying to rebuild our Oracle 11g server. I started off by wiping Oracle completely and kicked off the install again. The install goes smoothly, but does not create the Listener. I've been trying to use netca to create it myself. The below is the output from netca:
Listner Control complete.
Listener start failed.
Looking in the netca trace file, I see the following error (note I'm only including the error with a few lines before):
