No more data to read from socket error

Question

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

Answer 1

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

Answer 2

Downgrading the JRE from 7 to 6 fixed this issue for me.

Answer 3

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.

Answer 4

This is a very low level exception, which is ORA-17410.

It may happens by several reasons:

1. A temporary problem on networking.

2. Wrong JDBC driver version.

3. Some issues with special data structure (on database side).

4. Database bug.

In my case, it was a bug we hit on the database, which needs to be patched.

Answer 5

We were facing same problem, we resolved it by increasing initialSize and maxActive size of connection pool.

Maybe this helps someone.

Answer 6

Try two things:

1. 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.
2. If you are using Java this might help you: In java/jdk1.6.0_31/jre/lib/security/Java.security change securerandom.source=file:/dev/urandom to securerandom.source=file:///dev/urandom
