JDBC thin driver 8.0.5 giving SQLException: No more data to read from socket

H/W : sun4u sparc SUNW,Ultra-Enterprise
OS : SunOS 5.6 Generic_105181-16
JDBC driver : 8.0.5.0.0 (Production Release)
Oracle Server : 8.0.5
I am getting the following error "SOMETIMES". I am using a connection pool to connect to the server using the thin driver. Can anyone tell me why is this happening and how can I fix it.
Thanks,

ORACLE JDBC : java.sql.SQLException: No more data to read from socket

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...

Well, lot's of things could be causing this. Off the top of my head, in rough order of likelihood:
1) firewall - personal, on your box, or general, around the database, is reaping long-lived connections
2) connection wrappers on the database - ditto
3) your pooler is configured to terminate connections that are checked out of the pool for too long and you're exceeding that time for some operations
4) your database or it's listener is crashing out from under you (and possibly being auto-restarted by the time you look at it).

XI to jdbc error: No more data to read from socket

</SAP:Error>

Hi Sudeep,
This error most likely occurs when you use DB connection pool, which I think is the case in XI. When the JDBC adapter tries to connect to the database and discovers that the connection has been timed out/lost, then this exception is generated. Please have a look of the connection settings of your JDBC adapter and also at the note 831162.
Cheers...

Bug in Oracle JDBC thin driver (parameter order)

[ I'd preferably send this to some Oracle support email but I
can't find any on both www.oracle.com and www.technet.com. ]
The following program illustrates bug I found in JDBC Oracle thin
driver.
* Synopsis:
The parameters of prepared statement (I tested SELECT's and
UPDATE's) are bound in the reverse order.
If one do:
PreparedStatement p = connection.prepareStatement(
"SELECT field FROM table WHERE first = ? and second = ?");
and then bind parameter 1 to "a" and parameter to "b":
p.setString(1, "a");
p.setString(2, "b");
then executing p yields the same results as executing
SELECT field FROM table WHERE first = "b" and second = "a"
although it should be equivalent to
SELECT field FROM table WHERE first = "a" and second = "b"
The bug is present only in "thin" Oracle JDBC driver. Changing
driver to "oci8" solves the problem.
* Version and platform info:
I detected the bug using Oracle 8.0.5 server for Linux.
According to $ORACLE_HOME/jdbc/README.doc that is
Oracle JDBC Drivers release 8.0.5.0.0 (Production Release)
* The program below:
The program below illustrates the bug by creating dummy two
column table, inserting the row into it and then selecting
the contents using prepared statement. Those operations
are performed on both good (oci8) and bad (thin) connections,
the results can be compared.
You may need to change SID, listener port and account data
in getConnecton calls.
Sample program output:
$ javac ShowBug.java; java ShowBug
Output for both connections should be the same
--------------- thin Driver ---------------
[ Non parametrized query: ]
aaa
[ The same - parametrized (should give one row): ]
[ The same - with buggy reversed order (should give no answers):
aaa
--------------- oci8 driver ---------------
[ Non parametrized query: ]
aaa
[ The same - parametrized (should give one row): ]
aaa
[ The same - with buggy reversed order (should give no answers):
--------------- The end ---------------

Jdbc oracle jdbc-thin driver subname

I am working on Windows 2000 environment, using oracle8i 8.1.7 JDBC-Thin driver for use with JDK 1.2.x. The oralce8i 8.1.7 database is on another linux box. I can access the linux box through its ip address, but not by its hostname since it's not accessiable by the dns server. In my code, in the JDBCUrl, I used ip address instead of the hostname, e.g. "jdbc:oracle:thin:@10.0.113.108:1521:ora1". But I got the error like: "java.sql.SQLException: Io exception: The Network Adapter could not establish the connection". If I add a entry in my working machine's hosts file to map the hostname, I can fix the problem. But I don't know if this is the solution, or there is other better solutions.
Thanks
null

Using a hosts file entry is a common solution for problem where the dns lookup does not contain an entry for a RDBMS server platform.
The real solution is to resolve this issue :
"where the dns lookup does not contain an entry for a RDBMS server platform."

JDBC thin driver and Oracle 8.1.6

Hi,
I have installed Oracle 8.1.6 on Windows NT 4.0 with service pack 4 and using Oracle JDBC thin driver driver (classes111.zip). My application is multithreaded, but each thread maintains its own connection (and own set of Statements). Things are okay in single threaded mode, but in multi threaded mode, I get weird errors!
1. My resultsets are SCROLL_SENTITIVE and UPDATABLE
2. Sometimes, while updating a row, "No current row" SQLException is thrown, although a row exists that satisfies my select criteria
3. I am also calling executeUpdate() for inserting new rows and such rows are not seen by successive resultsets!
Appreciate any hints! Thanks!

Try this isntead.
java -classpath d:\jdbc\classes12.zip;. jdbccheckup
an error occured:
Exception in thread "main" java.lang.NoClassDefFoundError:jdbccheckup
Why??????

Connection error to 9i database using JDBC thin driver

I have no problem with my code connecting to an Oracle 8 database, just 9i.
I'm trying to debug in Visual Cafe (JDK 1.1.7) and have both the classes111.zip and the nls_charset11.zip in my CLASSPATH.
Any suggestions would be appreciated. Thanks

If you're using 8i 8.1.7.1 or 8i 8.1.7.0 thin JDBC drivers on NT, then you can get them to connect to 9i by applying the 8i 8.1.7.1 Patch available at:
http://technet.oracle.com/software/tech/java/sqlj_jdbc/htdocs/solsoft.html
You might have to register/login first.
Basically, it's just a case of replacing a class already in your classes111.zip or classes12.zip with the class in the patch.
Took me a while to find this, but it worked first time after patching. Hope this helps.

JDBC thin driver, failUTF8Conv

I browse through JDBC some records from an Oracle 8.1.7 DB with NLS_CHARACTER=EL8ISO8859P7 and greek data.
Some records (columns are type varchar2) are displayed ok, but at some other certain records, an exception occurs and I get:
"JBO-27022: Failed to load value at index 3 with java object of type java.lang.String due to java.sql.SQLException.
Error Message: Fail to convert between UTF8 and UCS2:failUTF8Conv"
How can this be solved?

Change expired password using oracle jdbc thin driver

Hello,
I have a java program that uses the oracle jdbc thin driver (ojdbc6 - version 11.2.0.3) for database connection. My question is if I have any possibility to change an expired password (java.sql.SQLException: ORA-28001: the password has expired) using the thin driver - NOT OCI?

No - the thin driver doesn't have any password management features.

          String url = "jdbc:oracle:thin:@son1129:1521:sonias";
          Connection con;
          String query = "select EMPNO, ENAME from EMP";

               Properties props = new Properties();
               try {
               props.put("oracle.net.authentication_services", "CYBERSAFE");

               props.put("oracle.net.encryption_types_server", "DES");
               props.put("oracle.net.crypto_seed", "4fhXXXX");
               } catch (Exception e) { e.printStackTrace();
               DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
               // ASO
               con = DriverManager.getConnection(url, props);
               stmt = con.createStatement();
               ResultSet rs = stmt.executeQuery(query);

Oracle jdbc driver information, which i obtained as per Note 94091.1
=============
Database Product Name is Oracle
Database Product Version is Oracle8i Enterprise Edition Release 8.1.7.1.1 - Production With the Partitioning option
JServer Release 8.1.7.1.1 - Production
JDBC Driver Name is Oracle JDBC driver
JDBC Driver Version is 8.1.7.0.0
JDBC Driver Major Version is 8
JDBC Driver Minor Version is 1

1. What JDBC Thin client Driver are you using? (version) If you don't know, open up the Manifest.
2. the JDBC/OCI driver is a thick driver. It uses the oracle client, and therefore should read the tnsnames.ora
3. You have yet to give us any ORA- errors, which would help immensely in troubleshooting.

OS Authentication using JDBC Thin driver

Hi
I have a problem while connecting to Oracle database using JDBC Thin Driver, Basically I am trying to connect using OS Authentication. The following explains clearly what I am trying to do.
String connectionURL = "jdbc:oracle:thin:@localhost:1521:XYZ";
String userName = "/";
String password = "";
java.util.Properties info = new java.util.Properties();
info.setProperty("user",userName);
info.setProperty("password",password);
conn = DriverManager.getConnection(connectionURL,info);
When executing the code I am getting an exception as follows.
java.sql.SQLException: Null user or password not supported in THIN driver
When i searched in the Oracle site i got the below information
Note:
By default, the JDBC driver retrieves the OS username from the user.name system property, which is set by the JVM. If the JDBC driver is unable to retrieve this system property or if you want to override the value of this system property, then you can use the OracleConnection.CONNECTION_PROPERTY_THIN_VSESSION_OSUSER connection property. For more information, see Oracle Javadoc.
I want to know how to set the OracleConnection.CONNECTION_PROPERTY_THIN_VSESSION_OSUSER connection property.
Advance Thanks

Based on your code, when you try to connect your username is null and the password is "/". You are not going to be able to get the OS password using Java.
