No more data to read from socket error

转载自:http://stackoverflow.com/questions/7839907/no-more-data-to-read-from-socket-error
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 at oracle.jdbc.driver.T4CMAREngine.unmarshalUB1(T4CMAREngine.java:1142) at oracle.jdbc.driver.T4CMAREngine.unmarshalSB1(T4CMAREngine.java:1099) at oracle.jdbc.driver.T4CTTIfun.receive(T4CTTIfun.java:288) at oracle.jdbc.driver.T4CTTIfun.doRPC(T4CTTIfun.java:191) at oracle.jdbc.driver.T4C8Oall.doOALL(T4C8Oall.java:523) at oracle.jdbc.driver.T4CPreparedStatement.doOall8(T4CPreparedStatement.java:207) at oracle.jdbc.driver.T4CPreparedStatement.executeForDescribe(T4CPreparedStatement.java:863) at oracle.jdbc.driver.OracleStatement.executeMaybeDescribe(OracleStatement.java:1153) at oracle.jdbc.driver.OracleStatement.doExecuteWithTimeout(OracleStatement.java:1275) at oracle.jdbc.driver.OraclePreparedStatement.executeInternal(OraclePreparedStatement.java:3576) at oracle.jdbc.driver.OraclePreparedStatement.executeQuery(OraclePreparedStatement.java:3620) at oracle.jdbc.driver.OraclePreparedStatementWrapper.executeQuery(OraclePreparedStatementWrapper.java:1491) at org.apache.commons.dbcp.DelegatingPreparedStatement.executeQuery(DelegatingPreparedStatement.java:93) at org.apache.commons.dbcp.DelegatingPreparedStatement.executeQuery(DelegatingPreparedStatement.java:93) at org.hibernate.jdbc.AbstractBatcher.getResultSet(AbstractBatcher.java:208) at org.hibernate.loader.Loader.getResultSet(Loader.java:1869) at org.hibernate.loader.Loader.doQuery(Loader.java:718) at org.hibernate.loader.Loader.doQueryAndInitializeNonLazyCollections(Loader.java:270) at org.hibernate.loader.Loader.doList(Loader.java:2449) ... 63 more

We use spring, hibernate and i have the following for the datasource in my applciation context file.

I am not sure whether this is because of application errors, database errors or network errors.
【No more data to read from socket error】We see the following on the oracle logs

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
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
