I'm trying to recover from a connection that is no longer valid, whether it timed out or was killed, etc. From the servlet, I call ((OracleConnection)connection).pingDatabase() to see if the connection is alive and if not recreate it

Java.sql.SQLException: Io exception: End of TNS data channel

Hello folks,
Has amyone encountered this exception? If so, could you please shed some light for what might be going wrong?
Here is my confuguration:
400MB RAM
1.2GHTz processor
Win2K Pro
Oracle server 9.0.1
JDBC Thin driver (libs for 9.0.1)
Scenario:
My Java code uses Oracle Spatial to insert SDO_GEOMETRY objects into my DB model.
I have a config file where I store my connection properties, e.g.,
<DBConnection name="twatest">
<JDBCDriver>oracle.jdbc.driver.OracleDriver</JDBCDriver>
<URL>jdbc:oracle:thin:@saturn:1521:saturn</URL>
<Username>user1</Username>
<Password>twatest</Password>
</DBConnection>
We have 2 schemas defined: user1 and twatest.
The problem first occured when I switched from user1 to twatest. Consequent attempt to run the process as user user1 failed! The Java SQL statements do not use schemas (so they default, I suppose, to the default schema for that particular user, in our case being user1-->user1, twatest-->twatest).
The problem happens in the following Java class (search for "HERE" to see where exactly the problem occurs):
package com.vividsolutions.twatest;

I tried to find information on this on the net, but seems that this problem only happened when people dealt with LOBs?!
Thank you very much!

Suresh -- I'd probably log a TAR with Oracle support for this question if you definitely need it resolved. Support have access to all manner of existing cases, so this may be something they have seen before.

Problem with ORA -03113 End of Communication Channel

Hello,
Oracle Database 10g Release 10.2.0.1.0 - Production
Windows Server 2003 Version V5.2 Service Pack 2
Im having this problem when executing an stored procedure that executes a SQL statement wich has uses db links... I get this end of communication channel error.. so I thought it was a network issue, but all connections are fine.
The thing is that the procedure works fine, but just out of the nothing starts to give that problem, shutting down the database would not correct the problem, only restarting the server will fix the issue temporarily. I checked the dump file related to the process am running and I found this, I think it might be like a memory problem but not sure

what do you recommend me to try here?

Hi Ogan,
I agree ! Of course we are often obliged to compose with minimal downtime, testing resources, editors, management, time etc.
I have the same problems but keeping the base version is a pain and if you consider 10.2.0.5 you won't have to install many patchsets after this one on the 10gR2 homes/databases. It's a "good" investment if you have to keep the 10gR2 for several years (going to 11g is more difficult than installing a patchset !)
Oracle patchsets are great and well tested and if you pay your Oracle license you pay for that ! The patchsets, patchset updates, support make the difference with the versions you can download "freely" on OTN.
Best regards
Phil

End of TNS Channel

Trimming of a string with a space in stored Procedure Returns ORA-03113 followed by ORA-03114.
Oracle Version = 8.1.7
Database character set - UTF8
We have this problem in many of the SP's, the problem not simulatable with WE8ISO8859P1 as characterset.
I appreciate any inputs to resolve this issue. Thanks
Sample Procedure:
CREATE OR REPLACE PROCEDURE End_of_channel_test(
a in varchar2,
m_errorid IN OUT NUMBER)
AS
end1 varchar2(10);
BEGIN
end1 := ' ';
end1 := TRIM(end1);
RAISE_APPLICATION_ERROR(-20000,end1);
END End_of_channel_test;

This is perhaps not the right forum now...
But try: select nvl2(trim(' '),'NOT null','NULL') from dual

ERROR : End of TNS data channel

java.sql.SQLException: Io exception: End of TNS data channel
HI,
We have a websphere application and the backend is oracle 8.1.7 on NT.
We use JDBC for connectivity to Oracle.
We are coming across the above mentioned error for some of the transactions.
Also since no ORA- number is returned i'm unable to get to the cause of the error.
If anyone of u has come across a similar situation then pl let me know the cause of the error and the solution to it.
Thanks,
Ravi

ElectroD,
Try using "LEFT OUTER JOIN" instead of LEFT JOIN alone. It might get through.
Thanks,

OC4J problem and End of TNS data channel

We are using Oralce 9iAS with OC4J to host our java application. Recently, we kept having problem with the application. The problem is when user enters username and password to login, the application doesn't do anything until we restart OC4J instance. After tracking down all the error log files, it looks like problem happened whenever the application get "SQL Exception: End of TNS data channel" error. I don't know why are we getting this "End of TNS data channel" error. I don't think it is the application's problem.
1)Does anybody have any idea why?
2)Does OC4J server need to be restarted every once a while.
Thanks in advance.

Hi Liya -
"End of TNS data channel" is usually a message sent by the database when something erroneous is occuring.
What version of the database, JDBC, and JDK are you using?
Are you getting any dump files from the database?
Can you describe a little more about what the application code is doing?

JDBC Thin Driver "End of TNS Data Channel

I don't know how much hope there is of getting this answered. It looks like most of these questions are going either ignored or simply abandoned by the Oracle staff, but here it goes.
I have an Oracle 7.3.4 database running on Netware 4.11. I was writing an app that would allow me to run a query and dump the output to Swing JTable.
I was using the JDBC 7.3.4 driver and was able to connect and run queries, however manipulating the resultset was difficult.
As I looked into moving the resultset data into a JTable, I realized I needed to make a custom Table model. JDBC 2.0 seemed to have all the features that would make this easy so I coded a TableModel that assumed JDBC 2.0 support.
I realized the 7.3.4 driver was not 2.0 compliant when I recieved an AbstractException when calling ResultSet.last()
I thought this would be no problem so I looked for a Oracle JDBC 2.0 Compliant driver that would support a 7.3.4 database.
I was happy to see that all JDBC thin clients claim to be backwards compatible. I downloaded JDBC 9.0.1 since I've upgraded to JSDK 1.3.1.
When trying to establish a connection I recieve the "IOException: End of TNS Data Channel."
I have tried all other JDBC drivers between 9.0.1 and 7.3.4 and the only driver that connects is the 7.3.4.
If anyone has any insight that could help me, please let me know. Thank you.

Is the class you have given is complete code or is it partical code?
Are you using any JDBC calls in your actual program ?
How big is this file /Temp/kongx.txt?
Please provide us the above details ?

[HELP] End of TNS data channel

[please CC: to me when you reply if possible]
i'm using
solaris 2.7, jdk 1.2.2, oracle 8i 8.1.6,
classes12.zip jdbc driver (the latest one for 8.1.6 that i downloaded a week ago)
when i recompiled & ran my used-to-be working code (with just newer jdbc driver & jdk), in run time, it kept giving me:
java.sql.SQLException: End of TNS datachannel
i'm positive that i'm using correct login/password/parameters for the oracle thin driver since the code was working fine.
any help would be appreciated.

JDBC Development Team said:
"I've never seen this before. Can you post a stack trace? Also, do you have small (tiny) test case?"
Do a search in this forum for "End of TNS Data Channel" and you should see at least 4 threads on this topic. The posts date back to May 1999. Shame on you if you haven't seen it before. Oracle hasn't issued a fix.
Here's my version of it:

Client: JDK 1.2.1, JDBC Thin Drivers 8.1.5

Yes, it definitely has to do with the language setting, and I do not have a database with a Chinese character set at my disposal.
No, by TAR I meant to officially contact the support that will take care of your problem, if you still need this, if you have a support contract. To have an idea on what TARS are, you can take a look at the metalink site (metalink.oracle.com) under the TARs tab.

End of TNS data Channel error

I am running oracle 8i v 8.0.3.0.6 on Netware. When trying to connect to an existing TNS Name(which works with all other item) using the JDBC thin client I receive the 'End of TNS data Channel' error.
Can anyone give me some direction as to what I can do.
Thanks;

If you are using the oracle thin driver, make sure you get the latest driver
from oracle.
Firewall could be an issue here, so try to make sure you set the
TestConnsOnReserve to true in the connection pool props.

Hi,
We are using the Weblogic application server for our web-based applications.
We defined a connection pool in it, which creates 2 connections to an Oracle
database i.e initial capacity 2 and maximum capacity 4. But every one in a
while when requesting data, I get the following error : SQLException : End

problem or database problem.If anyone has any idea please help,b'coz it is

Exhausted Result set and End of TNS data channel

Please reply to : [email protected] (there's hopeful :-)
Using the same code, but with different drivers I get :
8.1.7 Thin Driver : End of TNS data channel
8.1.7 OCI Driver : Exhausted Resultset
Both are talking to an 8.1.7 server.
The problems are coming at different points in the code, and seem
to be data/volume based - they are reproducible in the main, but
don't always happen.
I've checked the forums for both of these problems, but nothing
seems to match my approach - just loads of calls to simple
prepared statements generated for an OO/RDB mapping.
Any pointers appreciated - such as why these happen?
Thanks

End of TNS Data Channel

I still haven't seen a fix or a work around for the "End of TNS Data Channel" error.
(This is the problem trying to connect to a 7.3.x server using 8.x Thin JDBC drivers. For further details, search this forum for "End of TNS Data Channel" to read many related posts dating as far back as May 1999.

Hi,
I had arrived very late to this forum and I don't know if now
there is a solution or workaround related with "End of TNS Data

I'm trying to connect a HttpServlet with an Oracle 7.3.4 server
and I have the specific need to use JDBC 2.0 driver because I
must use it's table "scrolling" facilities, but allways I get
the same SQL Exception.
Please send me any suggestion about this topic to my email

Io exception: End of TNS data channel when Indexing

I am trying to create an index on a column which contains rules to be used with CTXRULE. I would also like to improve the wildcard search, so that searching for
"depletes" would be matched up with the rule "%deplete%". I am also using a blank stopwords list as the rules are quite precise.
For that, I am creating the following preferences:
-- create new pref
exec Ctx_Ddl.Create_Preference('wildcard_pref', 'BASIC_WORDLIST');
-- allows better %abc%
exec ctx_ddl.set_attribute('wildcard_pref','SUBSTRING_INDEX', 'TRUE');
or
-- allows better abc%
exec ctx_ddl.set_attribute('wildcard_pref','prefix_index', 'YES');
exec ctx_ddl.set_attribute('wildcard_pref','PREFIX_MIN_LENGTH', 3);
exec ctx_ddl.set_attribute('wildcard_pref','PREFIX_MAX_LENGTH', 10);
-- drop existing stoplist pref
exec ctx_ddl.drop_stoplist('stoplist_pref');
-- create new stoplist pref
exec ctx_ddl.create_stoplist('stoplist_pref');
create index testrule_IDX on test_table(rules)
indextype is ctxsys.CTXRULE
parameters ('Wordlist wildcard_pref Stoplist stoplist_pref');
The above script works fine until it comes to creating the index, upon which I get the following error (line numbers different):
Error starting at line 11 in command:
create index testrule_IDX on test_table(rules)
indextype is ctxsys.CTXRULE
parameters ('Wordlist wildcard_pref Stoplist stoplist_pref')
Error at Command Line:11 Column:0
Error report:
SQL Error: Io exception: End of TNS data channel
However, if I don't include the additional attributes, the index gets created without any issues.
I am using Oracle 10.2.0.3 on UNIX, and running the code through SQL developer.
Any help would be greatly appreciated.
Thanks.

According to the documentation wildcards and prefix and substring indexes are not supported with ctxrule. If you try to use these things, the index may not get created. If you are creating your index from SQL*Plus, you should get a specific error message telling you that or you might get more information from ctx_user_index_errors. If you try to use a wildcard in your rules, it seems to cause the whole query to return no rows. However, if you user a lexer with index_stems, it seems to return all words that have the same stem word as the search word in the rules. Please see the demonstration below with and without the index_stems.

What does "End of TNS data channel" mean?

DB: Oracle 8
OS: WinNT
I am trying to add a new connection via the connection manager. I
have tested my connection to the DB using SQL NET and know that
TNS names are correct. However when I enter all details in the
connection manager and click "Test Connection" I get the
following error message.
"End of TNS data channel"
Anyone have any ideas,
Thanks,

I have used all possible configurations using the sid, and
service name. I also succesfully used one of ODBC connections,
however the Connection 'wizard' wouldn't add it to its Connection
list.

If you are trying to connect to an 8.0.5 DB on LINUX,
