How do I troubleshoot the error "javasqlSQLException: No more data to read from socket" when I'm trying to connect to my Amazon RDS for Oracle instance?
I get the error "javasqlSQLException: No more data to read from socket" when I try to connect to my Amazon Relational Database Service (Amazon RDS) for Oracle DB instance.
"I get the error "javasqlSQLException: No more data to read from socket" when I try to connect to my Amazon Relational Database Service (Amazon RDS) for Oracle DB instance.ResolutionYou get the error “javasqlSQLException: No more data to read from socket“ because of a connectivity issue between the Oracle server and the client JDBC driver. The most common reasons and troubleshooting options for these connection failures are the following:The connection is abruptly terminated due to network interruptions: To troubleshoot this issue, check the alert.log file of the instance for any TNS timeout errors posted during the time when the connection timed out from the application end. For more information, see Oracle documentation for TNS timeout errors. For more information on accessing the alert log for RDS instances, see Oracle database log files.The connection is terminated because of Oracle errors on the server side: Check the alert.log file for ORA-0600 or ORA-07445 errors. Collect the trace dump for specific Oracle errors. Check if these errors have a known fix provided by Oracle support.The client-server connection is not active: To troubleshoot this issue, set the parameter SQLNET.EXPIRE_TIME to a specified interval, in minutes, to send a probe that verifies that the client-server connections are active. For more information, see Oracle documentation for SQLNET. EXPIRE_TIME.The RDS for Oracle instance is not available or was restarted when the JDBC client was trying to use an existing connection to the Oracle server: To troubleshoot this issue, retrieve events for the RDS instance and check if the instance was restarted or stopped when the connections were established from the JDBC client.The JDBC drivers used for connecting to the RDS for Oracle Instance are incompatible: To troubleshoot this issue, confirm that the version of JDBC driver is compatible with that of the DB instance. For the list of compatible JDBC drivers, see Oracle documentation for Compatibility matrix for Java machines and JDBC drivers used with ODI. If the JDBC driver is incompatible, download the latest JAR file in your source code. Then, include this file in your classpath when you compile the class that creates connections to the database. For more information, see Downloading the JDBC driver.The memory components on the client side cause timeouts: To troubleshoot this issue, check if the Oracle Data Integrator has memory components on the client side that cause unwanted timeouts. Be sure that you set the correct values for these components on the client side. For more information, see Oracle documentation for How to define Java options (such as the limits of memory heap, the location of non-Java libraries, etc.) in ODI.Related informationOracle documentation for A "No More Data to Read From Socket" error has been signaled from an ODI integration interfaceFollow"
