I got ” ORA-12152: TNS: Unable to send Break Message ”  error in Oracle database.

 

ORA-12152: TNS: Unable to send Break Message

 

Details of error are as follows.

ORA-12152: TNS: Unable to send break message.

Cause: Unable to send break message. Connection probably disconnected.

Action: Reestablish connection. If the error is persistent, turn on tracing and reexecute the operation.

 

 

cannot reclaim string bytes disk space

This ORA-19804 error is related with the Unable to send break message. Connection probably disconnected.

Reestablish connection. If the error is persistent, turn on tracing and reexecute the operation.

 

This issue can also be reproduced with SQL*Plus, so it is not particular to the JDBC driver.
Underlying layer / TCP network has disconnected the client-server communication link (TCP socket).

In this particular case, it is caused by a faulty ethernet card resulting in ORA-12152: TNS:unable to send break message.

Replace the client faulty ethernet card.

 

Or To solve this error, set  sqlnet.expire_time=100 in sqlnet.ora ( under $ORACLE_HOME/network/admin ), it will be solved.
