ORA-12518: TNS:listener could not hand off client connection (DBD ERROR: OCIServerAttach)

Hi again,
I'm on my enterprise management console and Database Instance and Listener shows the green arrow, but the Agent Connection to Instance shows a red downward arrow and the error:
Status: Failed
Details: ORA-12518: TNS:listener could not hand off client connection (DBD ERROR: OCIServerAttach)
My OraClrAgnt service is up and running (using winxp pro, oracle 11gR2), I'm on my home pc, all my ports are open (my machine's name is "abigail" and it is dmzhost)
Any suggestions to resolve this error?

Listener (and database instance) does not starts up automatically: ORA-12514: TNS:listener does not currently know of service requested in connect descriptor

Hi at all.... I'm a newbie with database oracle.,
I have the follow problem:
I installed Oracle Database 11g R2 XE on my guest operating system CentOS 6.5.
I have changed the hostname in my SO CentOS (where is installed oracle 11g R2 XE) after installation was completed successfully.
-) Before and during installation the hostname was localhost.
-) After installation I changed the hostname in VMCentOS
From the moment I changed the hostname, nothing starts up automatically. In particular, the listener and the database instance does not starts up automatically.
When I starts up the listener manually and I try to connect to database instance with SQLPLUS i get this error:
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
I think that the problem is due to the changed hostname because I, for testing and debugging purpose, re-installed a new OS CentOS virtual machine, re-installed oracle database 11g and I have not got that problem. The database instance and the listener starts up automatically!
Can any one tell me if maybe the problem is related to the hostname changed? ... and Why?
P.S.: After changed the hostname I have also modified the listener.ora and the tnsnames.ora by modifying the HOST with the correct hostname.

Moreover in /etc/sysconfig there isn't any file oracle-xe!!!
At this point, I suspect that something in the installation I mistook.

TNS listener error "ORA-12514: TNS:listener..."

Hi all,
I have a problem with my listener on Oracle 11.2.0.2.
I am more of a developer than a DBA, and I do not have a DBA to consult, so I hope you can address me, please.
I have 2 DB instances running on the same machine ORCL and ORCL2 on port 1521, both using the same listener "LISTENER" as well on port 1521.
In my TNSnames I had to add yesterday as well a new entry to a DB (ORCL3) hosted on a different machine.
Since then, I can connect to ORCL and ORCL3 without problem via sqlplus, but I get the below error when I connect to ORCL2:
ORA-12514: TNS:listener does not currently know of service requested in connect
descriptor
I think the answer is to have to separate listeners for ORCL and ORCL2, but I have had several failed attempts.
Can you please advise on what I need to do? I have looked at various sites, but if you are not too experienced with listeners, they are not really very clear.
Thanks

Hi, thanks.

Error ORA-12505, TNS:listener does not currently know of SID given in connect descriptor

I have a java code that tries to connect to my oracle database.Below given the code snippet.
I am getting error when I ran this code.
Java code.

         return;
Error I am getting is

Obviously there is no handler for XE service.
Maybe you changed hostname(this should be "Owner-PC") ?
Try to manually start/stop db and see if there are some errors:
sqlplus / as sysdba
startup
shutdown immediate
If after that you still can't find cause, try to ask on oracle db forum.

ORA-12526: TNS:listener: all appropriate instances are in restricted mode

Hi all,
I am trying to connect to Oracle10.2.0.2 in solaris9 as
conn sys/password@dbname as sysdba
but after this attempt it showing
ORA-12526: TNS:listener: all appropriate instances are in restricted mode
but if i connect like this
conn sys/password as sysdba
it works.
Can some one give me the solution for the same?
Thanks
Vipin

Hi,
When you want to connect to database there are majorly two kinds of protocols are involve
1. TCP and
2. IPC
when you are talking about <username>/<password>@<servername > then though you are on same server you are refering to TCP protocol and when you are talking about <username>/<password> then you are refering to IPC protocol
now here when you are going to connect to your database through
conn sys/password as sysdba
its working fine because you are using IPC and if you connect through
conn sys/password@dbname as sysdba
it will show you error because you are using Listener TCP.
So i think that you need to check your listener status and database status both and give the output.
Thanks

ORA-12528: TNS:listener: all appropriate instances are blocking new connections

I'm working with OBIEE 11.1.1.5, with Ora DB 11.2.
Suddenly, the OBIEE is not accessible.
The logs showed that the issue is DB connectivity.
When I try to enter directly to the DB via sqlplus I get the error:

ERROR:
ORA-12528: TNS:listener: all appropriate instances are blocking new connections
I tried restarting server, DB, listener, but nothing helped.
I've Googled and saw that I need to unregister some old connections, which were not closed correctly, i.e. entering DB and delete some records,
but I cannot login to the sqlplus.
I failed login as sys, system, scott - on the same error.
How can I solve this issue?
