No more data to read from socket only in 2nd and 3rd database

Hi,
I'm developing an application for a client with three independent login modes, each one with an independent database.
I'm using the following products:
Oracle 9i database (9.2.0.6.0)
Oracle Content Management SDK 10g (9.0.4.0.0)
Oracle Workflow (2.6.3.0.0)
Oracle Application Server 10g (9.0.4.2.0)
In development, I've these products installed in x86 machines with Windows 2000. I've no problems and no errors.
In the client, I've the same products and versions but installed in a Solaris Machine and I've the following error ONLY when I use the second and the third login modes (not always, maybe only in 50% of the times I submit data in the application). In the first login mode I have no problems. The code for the different modes is essentially the same so I don't understand what is the problem. I don't have access to the client server so I can't make a debug.
The error is:
Caused by: java.sql.SQLException: No more data to read from socket

I'm using oracle jdbc thin driver.
As data source class I'm using jdbc.pool.OracleConnectionCacheImpl.
Anyone have a clue what is happening?

Have you resolved this? I am getting the same error, but after restarting my webserver and re-establishing my connection pools it works(for a while). I need to find the root.
Thanks for any help,

"No more data to read from socket."?

Hi everybody,
We recently migrated from Oracle 10g Database Enterprise Edtion to Oracle 11g R2 Database Enterprise Edition
with Data Guard and a dedicated standy-by database. The database is a data source for multiple applications.
Among others, we are using two JBoss 4.2.3 GA application servers which run together in a clustered configuration.
During our migration of our database, we also updated our OJDBC thin drivers from Oracle within our JBosses. We
replaced the ojdbc14.jar with ojbc6.jar (Oracle 11g 11.1.0.7.0) and updated or added referenced libraries as well.
Since our migration we experience an unfamiliar problem from time to time. Suddenly our deployed EJBs crash with
the exception "SQLException: No more data to read from socket." The occurence is rather random than bound to
a specific bean. The only noticeable thing is that it appears more often when there is more work load on our
JBosses.
Our only solution up to now is to shutdown our JBosses, restart the database and restart our JBosses again.
Depending on our work load we do this from every two days to every 4 hours.
I googled the message and even found several hundred hits that mentioned the exception above, but none of
them got really solved, instead people found some case of work around for them. But none of them worked for us,
since this exception seems more general and can have multiple causes.
We did not have this problems when we were using the Oracle 10g database. Currently I am not sure if this problem
is related to the new Oracle 11g R2 database, the new OJDBC thin driver or JBoss.
Anybody experienced the same problem? And maybe even got it properly solved?
If you need further information, just ask. I will happily offer as much information as possible to solve this.
Greetings,
CB

Hi,
I remember that we received similar error after upgrading the database from 9.2.0.7 to 10.2.0.4 in one of our application using JDBC 10.1.0.5. We worked with Oracle support, and they provided us with patch Patch 5851267, that resolved our problem.
So I would recommend you to do the same.

scott --
which jdbc versionare you using ??
if not the 816sdk -- try it ...
make sure you match up with the jdk version ...
note: jdk 1.2 functionality is not in any of the orcl drivers
yet.
check out for this faq (3rd question -- i think) for more details
on jdk 1.2 support :
http://technet.oracle.com/tech/java/sqlj_jdbc/htdocs/jdbc_faq.htm
in general -- this occurs due to several different conditions :
verify that the connections string is correct :
for thin -- the hostid:port:sid must match the listener you're
trying to connect with -- and a tcp/ip connection on the server
ust exist.
for oci driver make sure the "tnsname" entry being specified
exists and has the same information in its "entry" correct (i.e.
matches the listener values)
also make sure the listener and the orcl instance are started.
also make sure you're using jdk 1.1.x with 8.1.5 or lower
drivers.
816sdk can be used with jdk 1.1 or 1.2 if you are using the
correct jdbc driver version from otn to match the jdk version.
only jdk 1.1.x functionality is available in the jdk 1.2 driver
at this time.
also make sure you're using a thin driver if in an applet.
thin or oci in a servlet is ok if properly set up.
without more info --
i can't tell which of these "setup or condition" issues applies
to your situation ...
always provide :
jdk details,
applet vs. application vs. servlet,
jdbc driver version number and type(thin/oci)
also server version in all cases and if oci driver is being
used -- the oracle client version,
it's always better to provide too much detail with java
issues than just an error message ...
i hope this helps ...

ORA-17410: No more data to read from socket

Hi,
I have a dmp exported from Oracle 9i (9.2.0.1.0) and I'm using it on 10g (10.2.0.1.0). Everything works fine except this type of code:
select *
from table_name
where column_name = 3;
column_name's type is NUMBER(1,0). I only have this problem when column type is NUMBER(1,0). I changed the type from NUMBER(1,0) to NUMBER, but I still get this error when using this column...
When running this code I get in less than 5 seconds ORA-17410: No more data to read from socket and nothing else works anymore until I disconnect and connect again to the DB. When I run this code on Oracle 9i it works. I only have this problem on Oracle 10g.
Can you help me?
Thx.

I don't know how to check the IDLE_TIME for the logged in user, but IDLE_TIME is expressed in minutes and I get this error in 2-5 seconds.
I exclude network problems because I get this error even when running the code on the server using SQL Developer, not only from the application and other complex functions and procedures are working fine if they don't use columns with type NUMBER(1,0) in where statements.
Thx for your answer.

Error code: 17410: No more data to read from socket

We have a strange issue.
We have a stored procedure which we invoke using JDBC code. Calls to this stored procedure runs fine on 2 databases but fails on the 3rd one. If we run the stored procedure using SQL Plus, it works fine.
SQLException being thrown is:
java.sql.SQLException: No more data to read from socket
Oracle database version is Oracle9i Enterprise Edition Release 9.2.0.7.0 - 64bit Production in all three environments
While debugging the issue we figure the order of Java code made a difference while invoking the stored procedure that did not initially work.
Original Code:
ArrayDescriptor desc = ArrayDescriptor.createDescriptor( "SCHOOLLISTTYPE", conn );
StructDescriptor structdesc = StructDescriptor.createDescriptor( "SCHOOLCODEOBJ", conn );
Object[] attributes1 = { new String( "00131700" ), new String( "00" ) };
STRUCT empType1 = new STRUCT( structdesc, conn, attributes1 );
Object[] attributes2 = { new String( "00115900" ), new String( "01" ) };
STRUCT empType2 = new STRUCT( structdesc, conn, attributes2 );
Object[] attributes3 = { new String( "03078200" ), new String( "00" ) };
STRUCT empType3 = new STRUCT( structdesc, conn, attributes3 );
Object[] arrayElements = { empType1, empType2, empType3 };
ARRAY newArray = new ARRAY( desc, conn, arrayElements );
CallableStatement ps = conn.prepareCall( "{call AWSchools.Names (?, ?, ?)}" );
Throws the SQLException mentioned above.
But if I change the code to:
StructDescriptor structdesc = StructDescriptor.createDescriptor( "SCHOOLCODEOBJ", conn );
Object[] attributes1 = { new String( "00131700" ), new String( "00" ) };
STRUCT empType1 = new STRUCT( structdesc, conn, attributes1 );
Object[] attributes2 = { new String( "00115900" ), new String( "01" ) };
STRUCT empType2 = new STRUCT( structdesc, conn, attributes2 );
Object[] attributes3 = { new String( "03078200" ), new String( "00" ) };
STRUCT empType3 = new STRUCT( structdesc, conn, attributes3 );
Object[] arrayElements = { empType1, empType2, empType3 };
ArrayDescriptor desc = ArrayDescriptor.createDescriptor( "SCHOOLLISTTYPE", conn );
ARRAY newArray = new ARRAY( desc, conn, arrayElements );
CallableStatement ps = conn.prepareCall( "{call AWSchools.Names (?, ?, ?)}" );
code works fine.
This is strange as the ArrayDescriptor and StructDescriptor and independent objects till we invoke ARRAY newArray = new ARRAY( desc, conn, arrayElements );
Why would creating the ArrayDescriptor after we have done with arrayElements and desc make a difference?
And this happens only with one database server. The original code works fine in other 2 oracle database.
We did search in many forums about the error "No more data to read from socket". Seems this is a dark error which does not have any convincing answers.
Any help will be greatly appreciated.
Thanks.

enable gateway tracing by setting HS_FDS_TRCE_LEVEL=255 in your DG4MSQL configuration file. Then open a new SQL*Plus window and execute:
select user from dual@<dg4msql db link>;

ORA-17410: No more data to read from socket error

Hi
iam getting "No more data to read from socket error" on tomcat screen.
I have tried to explain the scenario, thats why it looks lengthy.
Any help is appreciated.
The application is calling a procedure which inturn tries to load class files and this error comes.
The database is on Oracle 9i (9.2.0.5) and we maintain it as a standby database.
Steps taken to create the standby database.
1. I have taken the cold backup of production database and copied it to Standby server
2. Created the oracle service on the Standby server. created the pfile and pwd file
3. Get the database to Nomount
4. recreate the controlfile
5. once in mount state, archive logs are copied from production and applied using
" recover database using backup controlfile"
This database was opened and started getting errors on tomcat screen.
Following are the things i tried to resolve the error:
1. I have put the latest JDBC drivers on oracle as well as at application end.
2. i can see all java files in Enterprise Manager on the Host Machine.
But through TOAD when i go to "Schema Browser" of "SYS" there are no java
files under "java tab" its empty.
3. I have run
C:\oracle\ora92\javavm\install\ initjvm1.sql
and few other java related scripts from "RDBMS" folder.
4. I have check listener config . Tried restarting the listener followed by starting the database.
I think there could be some connectivity issue or is there any parameter which needs to be set.
I would really appreciate any help.
Thanks,
Jerry

I am not very sure but can u do this on Standby Server? Looks like queries are only allowed on standby server in 11g.

[solaris 8] Oracle 8.1.6 EE: no more data to read from socket

Hi,
I'm sorry for writing to this list, but it is the most related I could find.
I installed Oracle 8.1.6 EE on a sparc 5 with solaris 8. I had to install the thread patches for solaris 8 because the emn0 process of oracle was dying every 30 minutes.
After that, the DB seemed to work ok, but when running a heavy java process (jdbc),
the process reports "java.sql.SQLException: No more data to read from socket".
Have anyone experienced this kind of problem ?
I decided to reinstall solaris 7... Could anyone help me ? comments ? suggestions ?
Thanks in advance.
Gabriel

Reason: the ORACLE server process crashes (sometimes), and the result is the "empty"
socket.

Java.sql.SQLException: No more data to read from socket

Hello,
we're now facing some strange problem which is probably caused by some malfunctioned connections being present in connection pool. The MGP process is failing for some clients with following error message. During the MGP process, some users are processed without any problems and some encounter this exception. I tried to restart the DB and both OL servers (we have 2 OL servers, on one of them is running MGP), but it didn't help.
Some time before I restarted the servers, we were also occasionally facing "Server connections exceeded" error message, but I don't think this is relevant...
We're using 10gR2 OL servers and 10gR2 RDBMS.
Any ideas what could be wrong?

I'm not using localhost, but the host name. We just today notified some other network problems on this server and discovered there're 2 network cards - one of them which wasn't connected was configured for DHCP and the other one was configured properly with fixed IP address. We disabled the disconnected network card and it looks like the problems with other applications is solved so we'll se if the Mobile Server is also cured...

These exception occures every hour after the connection pool is being closed and refreshed.
Also there are a lot of the follwoing warnning in the log :
<BEA-001074><A JDBC pool connection leak was detected.
Does these two problems connected? What can we do in order to solve it?
Thanks

Also there are a lot of the follwoing warnning in the log :
<BEA-001074><A JDBC pool connection leak was detected.
Does these two problems connected? What can we do in order to solve it?Hi. The problems are not directly related, but may have the same cause.
Something is killing your DBMS connections out from under the driver.
Do you have a firewall between WLS and the DBMS, or a flakey network?
Contact BEA support to get the 8.1sp2 patch for getting meaningful
connection leak traces (CR209251_81sp2.jar). When that patch is installed
the leak messages should show a full stack trace of the application code
where the connection was obtained. It is that application code that
somehow failed to close the pool connection, causing a pool leak. I
suspect that the application code got an unexpected exception, such as
when/if the DBMS/network/firewall killed a connection. In this case I
believe the application went through an exception-handling path that
forgot to close the connection.

SQLDeveloper tool script execution aborts with Error report: No more data to read from socket

Hello,
Strange behaviour of the SQLdeveloper tool while executing script with typical DDLs like:
Create Table,
Alter Table
Create Trigger ( use of :new and : old attributes in tehe body of trigger ).
Insert Into....
Scripts works ok from time to time.
But sometimes coincidentally aborts with the error :
Error report:
No more data to read from socket
Do not understand where is the problem.
Scripts works ok when executed in SQL*Plus on server ( where Oracle RDBMS resides ).
The version of SQLDeveloper is
Version 3.2.20.09 Build MAIN-09.87
The version of RDBMS is 11.2.0.2.0 .
Thanx for any reference or direction or hint for upgrade or experience.
Greetings,

Welcome to the forum!
Please provide the 4 digit Oracle version (result of SELECT * FROM V$VERSION) for the source and target servers; 10g and 11g are not versions. You also mention sql developer so what is the exact version you are using?

You can't delete the "OF out_a.ALLOCATION_ID" of the for update clause or you would get a syntax error by leaving FOR UPDATE OF with nothing specified after it.
Also you original statement said

But now you say that if you delete the "OF..." the problem doesn't happen and the code compiles on 10g.
Does the original code compile on 10g or not? Does it compile on 11g or not? After the original code is migrated to 11g does it compile? That is, the code is there can you manually compile it?

Error report:No more data to read from socket when compile package

We are going to migrate db from oracle 10g to oracle 11g. But when compile a package which is fine on oracle 10g, an exception "Error report:No more data to read from socket" throws on sql developer and break the connection. We have researched the issue and found if modify some code on a cursor, the issue will not happen.
code:
PROCEDURE DELETE_MANU_INTERV_BORROWS(
p_borrow_id IN NUMBER,
p_asset_id IN NUMBER,
p_nsb_coll_type IN VARCHAR2,
p_nsb_coll_code IN VARCHAR2,

p_settle_date IN NUMBER,
p_trans_type IN VARCHAR2,
p_status OUT VARCHAR2,
p_shorts_cursor OUT SYS_REFCURSOR
IS
var_end_settle_date GEC_IM_ORDER.SETTLE_DATE%type;
CURSOR exist_allocation IS
SELECT out_a.ALLOCATION_ID FROM
GEC_ALLOCATION out_a,
GEC_BORROW b,
GEC_IM_ORDER o,
GEC_TRADE_COUNTRY gc,
(SELECT f.FUND_CD, f.BRANCH_CD, tc.TRADE_COUNTRY_CD, NVL(gc.COLLATERAL_CURRENCY_CD, gbk.COLLATERAL_CURRENCY_CD) as COLLATERAL_CURRENCY_CD
FROM GEC_FUND f
LEFT JOIN GEC_G1_BOOKING gbk ON f.fund_cd = gbk.fund_cd AND gbk.TRANSACTION_CD = 'G1L' AND gbk.POS_TYPE = 'NSB'
LEFT JOIN GEC_G1_COLLATERAL gc ON gc.G1_BOOKING_ID = gbk.G1_BOOKING_ID
LEFT JOIN GEC_TRADE_COUNTRY tc ON gc.TRADE_COUNTRY_CD = tc.TRADE_COUNTRY_CD
) loan_info
WHERE b.BORROW_ID = out_a.BORROW_ID AND
out_a.IM_ORDER_ID = o.IM_ORDER_ID AND
o.FUND_CD = loan_info.FUND_CD AND
o.ASSET_ID = p_asset_id AND
gc.TRADE_COUNTRY_CD = o.TRADE_COUNTRY_CD AND
o.TRANSACTION_CD = p_trans_type AND
loan_info.COLLATERAL_CURRENCY_CD = p_nsb_coll_code AND
loan_info.BRANCH_CD = p_branch_code AND
o.SETTLE_DATE >= p_settle_date AND
o.SETTLE_DATE <= var_end_settle_date AND
b.STATUS = GEC_CONSTANTS_PKG.C_BORROW_MANUAL
ORDER BY out_a.ALLOCATION_ID ASC
FOR UPDATE OF out_a.ALLOCATION_ID;
If delete the "OF out_a.ALLOCATION_ID" of the for update clause of CURSOR exist_allocation, this prolbem will not happen, and the code is comple succesfully on sql developer for oracle 10g.
Does anybody have any idea? I've googled the similer problems but still can't find a clue. I'll appreciate any help.

UPDATE set a.name=b.name
when not matched then
insert (a.id,a.name) values ( b.id,b.name);This code is giving error : No more data to read from socket error.
But when I am trying
MERGE INTO TABLE1
( SELECT ...
FROM VIEW1*
where a.column1='test' ) a UNPIVOT ("VALS" FOR cols IN ( .....columns to unpivot.......))
) b ON ( a.id=b.id)
WHEN MATCHED THEN
UPDATE set a.name=b.name
when not matched then
insert (a.id,a.name) values ( b.id,b.name);It's working properly.
Any idea why I am getting error with code 1?

You need to look for an Oracle specific error code and message. The error text you have posted does not seem to be an Oracle error.
The error however could result from an ORA-3113 end-of-file on communication channel.
This Oracle error means that the Oracle server process servicing your request (executing SQL or PL/SQL code) ran into a fatal error (potentially an Oracle bug). The server process then proceeds with a "crash dump" - writes an error to the database instance's alert log, writes a trace file and then terminiates abnormally.
It terminates without telling the client and without tearing down the tcp client-server connection. When the client then attempts to use this connection, the socket read fails. No data to read as the socket connection no longer exists.
But this is speculation - we need to see the actual Oracle error (from the server or from the client driver). And you seem to be using an Oracle client that suppresses Oracle error codes and text. Which places a serious question mark over the actual usability of such client s/w for Oracle client-server.
