No more data to read from socket error
OracleHibernateSpringJdbcOracle Problem Overview
We are using Oracle as the database for our Web application. The application runs well most of the time, but we get this "No more data to read from socket" error.
Caused by: java.sql.SQLRecoverableException: No more data to read from socket

We use spring, hibernate and i have the following for the datasource in my applciation context file.
<bean class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close" id="dataSource">
<property name="driverClassName" value="${database.driverClassName}" />
<property name="url" value="${database.url}" />
<property name="username" value="${database.username}" />
<property name="password" value="${database.password}" />
<property name="defaultAutoCommit" value="false" />
<property name="initialSize" value="10" />
<property name="maxActive" value="30" />
<property name="validationQuery" value="select 1 from dual" />
<property name="testOnBorrow" value="true" />
<property name="testOnReturn" value="true" />
<property name="poolPreparedStatements" value="true" />
<property name="removeAbandoned" value="true" />
<property name="logAbandoned" value="true" />
</bean>
I am not sure whether this is because of application errors, database errors or network errors.
We see the following on the oracle logs

Oracle Version : 11.2.0.1.0
Oracle Solutions
Solution 1 - Oracle
For errors like this you should involve oracle support. Unfortunately you do not mention what oracle release you are using. The error can be related to optimizer bind peeking. Depending on the oracle version different workarounds apply.
You have two ways to address this:
- upgrade to 11.2
- set oracle parameter
_optim_peek_user_binds = false
Of course underscore parameters should only be set if advised by oracle support
Solution 2 - Oracle
We were facing same problem, we resolved it by increasing initialSize
and maxActive
size of connection pool.
You can check this link
Maybe this helps someone.
Solution 3 - Oracle
Another case: If you are sending date parameters to a parameterized sql, make sure you sent java.sql.Timestamp
and not java.util.Date
. Otherwise you get
> java.sql.SQLRecoverableException
: No more data to read from socket
Example statement:
In our java code, we are using org.apache.commons.dbutils
and we have the following:
final String sqlStatement = "select x from person where date_of_birth between ? and ?";
java.util.Date dtFrom = new Date(); //<-- this will fail
java.util.Date dtTo = new Date(); //<-- this will fail
Object[] params = new Object[]{ dtFrom , dtTo };
final List mapList = (List) query.query(conn, sqlStatement, new MapListHandler(),params);
The above was failing until we changed the date parameters to be java.sql.Timestamp
java.sql.Timestamp tFrom = new java.sql.Timestamp (dtFrom.getTime()); //<-- this is OK
java.sql.Timestamp tTo = new java.sql.Timestamp(dtTo.getTime()); //<-- this is OK
Object[] params = new Object[]{ tFrom , tTo };
final List mapList = (List) query.query(conn, sqlStatement, new MapListHandler(),params);
Solution 4 - Oracle
This is a very low-level exception, which is ORA-17410.
It may happen for several reasons:
-
A temporary problem with networking.
-
Wrong JDBC driver version.
-
Some issues with a special data structure (on database side).
-
Database bug.
In my case, it was a bug we hit on the database, which needs to be patched.
Solution 5 - Oracle
Try two things:
- Set in $ORACLE_HOME/network/admin/tnsnames.ora on the oracle server server=dedicated to server=shared to allow more than one connection at a time. Restart oracle.
- If you are using Java this might help you: In
java/jdk1.6.0_31/jre/lib/security/Java.security
changesecurerandom.source=file:/dev/urandom
tosecurerandom.source=file:///dev/urandom
Solution 6 - Oracle
I had the same problem. I was able to solve the problem from application side, under the following scenario:
>JDK8, spring framework 4.2.4.RELEASE, apache tomcat 7.0.63, Oracle Database 11g Enterprise Edition 11.2.0.4.0
I used the database connection pooling apache tomcat-jdbc
:
You can take the following configuration parameters as a reference:
<Resource name="jdbc/exampleDB"
auth="Container"
type="javax.sql.DataSource"
factory="org.apache.tomcat.jdbc.pool.DataSourceFactory"
testWhileIdle="true"
testOnBorrow="true"
testOnReturn="false"
validationQuery="SELECT 1 FROM DUAL"
validationInterval="30000"
timeBetweenEvictionRunsMillis="30000"
maxActive="100"
minIdle="10"
maxWait="10000"
initialSize="10"
removeAbandonedTimeout="60"
removeAbandoned="true"
logAbandoned="true"
minEvictableIdleTimeMillis="30000"
jmxEnabled="true"
jdbcInterceptors="org.apache.tomcat.jdbc.pool.interceptor.ConnectionState;
org.apache.tomcat.jdbc.pool.interceptor.StatementFinalizer"
username="your-username"
password="your-password"
driverClassName="oracle.jdbc.driver.OracleDriver"
url="jdbc:oracle:thin:@localhost:1521:xe"/>
This configuration was sufficient to fix the error. This works fine for me in the scenario mentioned above.

Solution 7 - Oracle
Downgrading the JRE from 7 to 6 fixed this issue for me.
Solution 8 - Oracle
Yes, as @ggkmath said, sometimes a good old restart is exactly what you need. Like when "contact the author and have him rewrite the app, meanwhile wait" is not an option.
This happens when an application is not written (yet) in a way that it can handle restarts of the underlying database.
Solution 9 - Oracle
In our case we had a query which loads multiple items with select * from x where something in (...) The in part was so long for benchmark test.(17mb as text query). Query is valid but text so long. Shortening the query solved the problem.
Solution 10 - Oracle
I got this error then restarted my GlassFish server that held connection pools between my client app and the database, and the error went away. So, try restarting your application server if applicable.
Solution 11 - Oracle
I seemed to fix my instance by removing the parameter placeholder for a parameterized query.
For some reason, using these placeholders were working fine, and then they stopped working and I got the error/bug.
As a workaround, I substituted literals for my placeholders and it started working.
Remove this
where
SOME_VAR = :1
Use this
where
SOME_VAR = 'Value'
Solution 12 - Oracle
Seemed to be an issue with a view. JDBC query was using a view. I took a guess, recompiled the view and error is gone.
Solution 13 - Oracle
In my case the error occurs running a simple query like this in SQLdeveloper:
select count(1) from tabel1 inner join tabel2 on table1.id = table2.id_table1 ;
I solved the error so...
select
/*+OPT_PARAM('_index_join_enabled' 'false') */
count(1) from tabel1 inner join tabel2 on table1.id = table2.id_table1 ;
