Problem: "end-of-file on communication chanel"

Hi,
I have an Oracle 7.3.4 Workgroup database who it was saved one
month ago on WinNT 4.0 Server, SP5, noarchive log mode, approx.
20Mb!
Today I had a error message from one client:
"Oracle internal error on Insert values [],[]..."
I checked the server and I find in the trace file the same
message!
Then I tried to make a full export of the base but after some
tables it stops for 2 hours on one table! Then I killed the
process and I restart the server!
But, after that, when I try to open the database, from SRVMGR23,
after the mounting, I receive the message:
"end-of-file on communication chanel "
What can I do?
Please help!!!!
Thanks in advance!

Hi,
once I had this problem and it had something to do with improper use of clobs inside the datastore procedure I used. If you are using user datastore, look at your datastore procedure, maybe your use of clob there is wrong.

The error, ORA-03113: end-of-file on communication channel, is a client driver error.
The client driver simply says "hey, the database server process servicing me has torn down our communication channel!". The communication channel is usually a TCP socket connection.
The client driver has no idea why. Thus you have to find the answer on the server.
The usual cause of this communication channel being closed, is the Oracle server process servicing the client session, crashing.
When an Oracle server process crashes, it does not tell the client. It usually writes an entry to the Oracle alert log, dump a trace file, and terminates. When terminating, it tears down any communication channels (TCP sockets) it may have opened.
Therefore you must look in
- the alert log file for an error message listing the crash (which will include the dump file name)
- look at this trace dump file (which is difficult if you're not familiar with Oracle internals)
- investigate the stack trace and error codes on Metalink (which often turns up the bug notes for this, plus any workarounds or available patches)
Usually however, one should log these types of Oracle server errors as a TAR with Oracle Support.

Error ORA-03113: end-of-file on communication channel in droppping a table

Good evening,
I am very new on Oracle and I have a problem with some tables. Without any reason, apparently, I can't drop some of my table. Oracle gives me this error:
ORA-03113: end-of-file on communication channel
and then close the connection of the user.
What I should have to do?
It is very important.
Thanks a lot
best regards

ORA-03113: end-of-file on communication channel while executing a query

Hi all,
I am getting following error while executing one of the query.
ORA-03113: end-of-file on communication channel
The query involves subqueries. At one point, in the second last condition of the whole query is the cause. what makes the query to disconnect from database.
I am pasting the whole query with highlighted part causing the error.

Awaiting your valuable suggestions.

I would start by compareing the explain plan of both versions of the statement.
Also by adding such a restriction you might change from an uncorrelated subquery to a correlated subquery. I'm not sure, because your code is hardly readably without formatting.
In any case you seem to select again and again from the same table. Maybe you should find a way to optimize to query in terms of io (less table access). Then this problem could go away.

Context Index World Lexer ORA-03113: end-of-file on communication channel

I have release 10g Release 1 (10.1.0.2.0) for Windows and trying to take advantage of the World Lexer.
My table is:
create table worldtest(
filename char(32),
content blob
I've created a preference for the WORLD_LEXER:
     begin
     ctx_ddl.create_preference('wlex', 'WORLD_LEXER');
     end;
Right now I'm working with 10,000 records of PDF, MS-Word, Text, and HTM documents. When I try and create a context index using this lexer:
create index i_ctx_wc on worldtest(content)
indextype is ctxsys.context
parameters ('lexer wlex');
The following error is returned, and I have to use drop index force to remove the index. Without 'Force' a message is return saying the index is an a loading state, but nothing is occuring.
create index i_ctx_wc on worldtest(content)
indextype is ctxsys.context
ERROR at line 1:
ORA-03113: end-of-file on communication channel
The indexing works fine when I leave the world lexer preference out.
Any suggestions would be wonderful. I've been banging my head on this one for a while.
Thanks.

Hi,
I couldn't reproduce (different version which is perhaps the problem). Check out bug 4056162. ORA-3113 related to the use of the world lexer. The resolution is not published externally, so no help there, but the bug is closed so perhaps support can provide some insight.
Thanks.

Did you actually read the alert-log ??
The problem is clear in there. Your datafiles are corrupted!!!
While the database is trying to correct these, a lot of ORA-00600 and ORA-07445's are generated.
Consult Oracle Support to get this resolved

Getting end-of-file on communication channel error on this query

Hi guys,
I'm getting the end-of-file on communcation channel error when running the following query in SQL PLUS, If run it in a stored procedure called through code of JDBC, it gave "no more data to read from socket" error. Any idea what went wrong? kind of frustrated now. We are using the Oralce 9.0.1.4.0, which suppose to fix some sdo_uion and sdo_buffer bugs. Thanks a lot!!
select SDO_GEOM.SDO_BUFFER((SELECT SDO_AGGR_UNION(MDSYS.SDOAGGRTYPE(GEOLOC, 0.011119487)) FROM GEOTEL_SOURCE where MSA='5000' and COMPANY_NAME ='AMERICAN FIBER SYSTEMS'),1.0,5,'unit=MILE arc_tolerance=0.05') from GEOTEL_SOURCE a where a.MI_PRINX = 1;

Hi Daniel,
Just tried the 9.2.0.2 patch, seems to work better now. At least I don't get the end-of-file on communication channel error. But how about the speed thing? I isolated the problem, and find out that sdo_aggr_union is taking too long to finish( 1 Hour!!! for 2300 lines with the same city. Any clue to optimize it, I tried some hint like /*+ordered*/ No_Merge and something like that, does not improve though. Thanks!

Xlmplsql parser error - end of file in communication channel

I receive:
end of file in communication channel error while trying to parse big xml files (at about 50 KB).
I am using plxmlparser_v1_0_2 with database 8.1.7. The xml and xsl files are stored in clob columns.
When I parse smaller files everthing works fine.
Is there any limitation for xml file size?
How to solve that problem?
Thanks in advance.
best regards

Thanks for your answer.
The system is a little bit complicated - there are several xsl files are imported by other xsl files.
I will try to prepare an example and send you.

Java Stored Proc - ORA-03113: end-of-file on communication channel

Help with error please.
Running java stored procedure and getting
end-of-file error. This error occurs after successful connection established.
Simple function returns a java.util.String that is a coded version of the DATE parameter. Procedure does not use a connection object.
Error message and description list below.
ERROR at line 1:
ORA-03113: end-of-file on communication channel
Cause: An unexpected end-of-file was processed on the communication channel. The problem could not be handled by the Net8, two task, software. This message could occur if the shadow two-task process associated with a Net8 connect has terminated abnormally, or if there is a physical failure of the interprocess communication vehicle, that is, the network or server machine went down.
Action: If this message occurs during a connection attempt, check the setup files for the appropriate Net8 driver and confirm Net8 software is correctly installed on the server. If the message occurs after a connection is well established, and the error is not due to a physical failure, check if a trace file was generated on the server at failure time. Existence of a trace file may suggest an Oracle internal error that requires the assistance of customer support.
I am currently looking into the trace file as suggested.
Thanks

ORA-03113: end-of-file on communication channel ERROR

After applying Database patch 3095277 to my 9.2.0.1.0 installation
in order to update it to 9.2.0.4.0,I'm getting ORA-03113: end-of-file on communication channel
ERRORS when attempting various tasks. This is a local installation running on a Windows XP Workstation.
I've even tried creating a new test database but the result is the same.
The reason for moving up to 9.2.0.4.0 is so I can start using Advanced Queuing, which I understand had problems in earlier releases.
However before the update I could at least create the JMS queue tables without ERROR whereas now I get the following errors when attempting to create a queue table in SQL Plus from within Enterprise Manager Console.
SQL*Plus: Release 9.2.0.4.0 - Production on Thu Sep 18 08:20:08 2003

BEGIN SYS.DBMS_AQADM.CREATE_QUEUE(Queue_name=> 'JMSQUE',queue_table=> 'JMSQTBL'); END;
ERROR at line 1:
ORA-03114: not connected to ORACLE
I would be grateful of any pointers as to how to resolve this problem.
Regards
Gary.

Chris, Thanks for the suggestion,
I took a look in the trace log and found the following entries that point to a ORA-00600 as you mentioned earlier.
This is only a test database so there's no great loss if
I have to re create it, but in saying that I did create a new test02 from scratch and had the same problem.
Is it posible something went wrong when applying the 9.2.0.4.0 patch ?.
Regards
Gary.

End-of-file on communication channel error when starting database

Hi All,
I have small problem, when we specify at startup without any pfile, it will go to read spfile,in our case it gives error end-of-file on communication channel.
Can anyone please help me to resolve this issue?
Thank you
Chirag

Oracle unable to spawn job slave processes should not prevent the instance from starting - these are not critical system processes and the instance can function without them (as it can when the job queue is set to zero processes).
The o/s failure message also does not make much sense.. overlapped I/O is Microsoft Windows term for async I/O. This can be used at file I/O level, but is also supported for any other file handle like sockets - thus applicable at the network layer too.
I'm a bit confused to how a PFILE versus a SPFILE startup can cause this. If that is the case, then surely there are something different ito init instance settings that triggers this error?
Can you copy and paste the actual SQL*Plus session (as already requested). Show us startup command (and params) used in SQL*Plus and the resulting messages (and errors displayed) in response to the startup.

8.1.7 Post-installation end-of-file on communication channel error

Hi everyone,
I got a problem with a new install of Oracle 8.1.7. First, I had 8.0.5 installed on Linux which contained a relative huge database. I wanted to upgrade to 8.1.7 and so, I installed it (with no default database). After I applied the patch (the setup_stubs.sh script) I tried to migrate the existing database with the odma (oracle data migration assistant). However, during the process odma gave me an error "An error occured while starting up the database..." I checked the log that came with the error message and it occured when it was trying to open the database i.e. the instance started, but when it came for mounting the database it displayed: ORA-03113: end-of-file on communication channel
I attempted to do the migration manually. So I tried to start the database using svrmgrl:
startup restrict pfile=$ORACLE_HOME/dbs/initSID.ora
and, of course, I get the instance started, but when it comes to mount the db, it gave me:
ORA-03113: end-of-file on communication channel
Anybody knows why I get this error on startup?
I checked my environment variables, my PATH and also made sure that svrmgrl was the version for 8.1.7. Everythings seem fine.
Any ideas?
Anything would be very much appreciated.
Thanks
joss

Hi,
the answer is simple. check first if TWO_TASK parameter is set to value from Ur tnsnames.ora. usually this environment variable must not be set for servers, only for client side. that means try 'unset TWO_TASK' and then should work.
best regards,
nicky
