Networking And Gateways :: TNS-12537 / Connection Closed
Oct 1, 2013
I am getting the error TNS-12537. In the SQLnet.ora file, if no IP Address is listed everything works fine and the listener starts without any issue. But one of the Security requirements we have is, we need to list all the client IP address on the SQLNet.ora file. I checked the Windows Firewall services and it is disabled.

I am facing ora - 12537 TNS connection closed issue while I am trying to login into database.I have installed Oracle database 11g on windows 7 premium OS.
I have 2 Database installed on the server one with the name of orcl and one with the name of mz50. When i am trying to connect from client side using toad to orcl i am able to connect to that db successfully but when i try to connect to mz50 DB i getting above mentioned error.
I check the tnsnames file as well as listener file and when i am trying to do tnsping both DB reply
I am trying to create a job that will execute a shell script on a remote server (Server B) when an existing job, on the local server (Server A), completes.
I have spent the last couple of days combing through Metalink, Oracle Documentation, AskTom, and Google. I know this is a relatively "new" feature/ability - released with 11.2 - but this particular error stack is no where to be found. I have attempted to be completely thorough with the information I provided, along with being diligent about masking important configuration information.
While the calling Job is starting the second job, the second job appears to timeout at 60 seconds and the job status is reported as failed with this error stack:
ORA-12537: TNS:connection closed ORA-06512: at "SYS.DBMS_ISCHED", line 4921 ORA-06512: at "SYS.DBMS_ISCHED", line 6853 ORA-29273: HTTP request failed ORA-06512: at "SYS.UTL_HTTP", line 1130 ORA-29261: bad argument ORA-06512: at "SYS.DBMS_SCHEDULER", line 3975 ORA-06512: at line 1
Configuration information:
Server A and Server B OS Version/Kernal Information: Oracle Linux Server release 5.8 x86_64 2.6.32-300.24.1.el5uek
Remote Scheduler Agent version, on both servers is: 11.2.0.3.1
Here is the listener status on Server B for db2:
serverb $$ lsnrctl status listdb2 LSNRCTL for Linux: Version 11.2.0.3.0 - Production on 23-JUL-2013 11:39:27 Copyright (c) 1991, 2011, Oracle. All rights reserved. Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=***))) STATUS of the LISTENER
[code]...
I have configured both servers with remote Scheduler agents and both databases have been configured and registered with the agents.
I have executed the shell script on Server B and it performs as expected.
I have the primary job calling the remote job, and that is performing as expected.
I have tested the connection from DB1 on Server A to DB2 on Server B with this
SQL> set serveroutput on SQL> DECLARE 2 versionnum VARCHAR2(30); 3 BEGIN 4 versionnum := DBMS_SCHEDULER.GET_AGENT_VERSION('ServerB.someplace.net');

and I have tested the connection from DB2 on Server B to DB1 on Server A with this
SQL> set serveroutput on SQL> DECLARE 2 versionnum VARCHAR2(30); 3 BEGIN 4 versionnum := DBMS_SCHEDULER.GET_AGENT_VERSION('ServerA.someplace.net');
I was trying to connect to a remote database from my client machine. Client machine runs a jsp code to connect to the database and execute a query. I have got oracle jdbc on my machine but still unable to connect to the database.
When checked in Google, i found that oracle connection manager has to be used to connect to the database from jdbc if the web server and database reside on different physical servers. But couldn't gather any further information regarding download and installation.
I do not have oracle connection manager on my system. I read in internet that it is shipped along with oracle 11g software. But i am not sure if that was the case in earlier version as well.
My question is where should i install oracle connection manager? (on database server or client machine) and is it possible to download and install only the connection manager as a stand alone so that i can connect to database from application?
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?
I have a JBOSS aplication server connect to database. When I tested on local, everything was ok. But when i test on real system , have a message "connection time out" on log file of app server while Oracle db still active. I viewed OEM, the system is executing the query :
"SELECT a.path songFilePath, a.BEAT beat from vp_song a, mst_my_album b "+ "where "+ "a.BEAT = b.BEAT "+ "and b.my_album_id IN "+ "(select my_album_id from (select my_album_id, ROW_NUMBER() OVER (order by my_album_id asc) "+ "R from mst_my_album where msisdn = ?) WHERE R BETWEEN ? and ?)";
I 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.
when i am connecting to my database in command prompt,sql * plus editor is it successfully connecting to the database but not connecting with the oracle client OEM.
but after connecting the LAN it is not connecting and also in the case when i am connecting to the internet through the USB datacard it is not connecting with the oracle client OEM.
how can i connect to database when the LAN,USB datacard connection.
TNS-12518: TNS:listener could not hand off client connection TNS-12571: TNS:packet writer failure TNS-12560: TNS:protocol adapter error TNS-00530: Protocol adapter error Linux Error: 104: Connection reset by peer
ODBC--call failed.TNS:listener was not given the SID in CONNECT_DATA (#12504)
TNSname sets the SID. SQL*Plus is able to connect from the client Windows XP Proff using the same name. Access, on the same client, uses the same Oracle driver to connect successfully to other Oracle databases. These other databases show equal tnsname (different name and SID...)
ODBC Data Source Administrator configures the database and the test connection is successful.
Cannot set up a link from Access to the Oracle database. At some point, I have created a new Access database and it did let me connect, view the list of tables, and set up links to several tables, but the next day I could not open any of the tables and the complain was: ODBC--connection to 'MYDB' failed.
It seems that SQL*Plus passes correctly the SID from the TNSname but ODBC, when invoked from Access, does not. Yet, ODBC does it right for other databases.
I am using the following piece of code to close the connection to the oracle database, I am using the context created in the previous step and passing it to the below code(connection.context)to release the connection.
if (connection.context == 0 || connection.ca == 0) return true; // Multithreading: get the communication area of the context struct sqlca & sqlca = *(connection.ca); EXEC SQL BEGIN DECLARE SECTION;
[code].....
When the above code is executed there is no exception thrown but the connection is not getting close. I am using the V$SESSION system views to monitor the connection created.
I there anything I am missing in my code for the connection closing to fail.
I'm working on a java program connected to a Oracle 9i db. I'm inexperienced about Oracle specific capabilities. The experienced Oracle users
I would like to know if there's a way to create a temporary table so that: - the table will be deleted automatically when a specific db connection closes (obligatory) - the table is visible for just one specific connection (optional)
What I would like to do is: 1 - Get the result set for query A. 1a - process the results 1b - store the results in a performance friendly way ( I thought about a temp table) 2 - Run query B over result set A. 3 - Run query C over result set A. X - The stored result set A has to be removed before/when the program ends (ideally when the db connection closes).
The problem isn't how to do this in java. The problem is to do it in a way so that the table will be automatically removed when the db connection used to create it will be closed so that's unimportant if the java program crashes or ends normally.
I'm using Oracle 11. I'm currently having some problem to start my Oracle database after database restore, hence unable to start my SAP application too.
Problem: After completing debug of procedure from SQL Developer, whenever I try to compile that procedure or execute any query from the SQL worksheet, I get the closed connection error message. However I can debug that procedure for any number of times. Any other activity for that database connection gives closed connection error.
(CONNECT_DATA = (SID = PLSExtProc) (PRESENTATION = RO) ) ) /*----------------------------------------------------*/ sqlnet.ora # This file is actually generated by netca. But if customers choose to # install "Software Only", this file wont exist and without the native # authentication, they will not be able to connect to the database on NT.
I have one production server with oracle 11g R2 DB. I have to change Server Hardware and thats why I have to install oracle 11g R2 DB on New hardware and test it. I had installed DB with software only option and copied the cold backup of production server. The hostname and ip address of both the servers are different. I had change the "db_domain" parameter into init.ora with the hostname.Now my question is that can the same db runs on the same network with different hosts. Change of "db_domain" parameter into the init.ora is enough or i have to follow some other procedure.
