them; it only takes a minute: Sign up Hibernate SQL Error: 17002, SQLState: null Io exception: Connection reset up vote 0 down vote favorite We're using hibernate 3 and c3p0-0.9.1. We've an Hibernate criteria based query to check the keyed in user name and password from database tables as well as other queries. During execution of first query i.e sql state = 08006 error code = 17 002 websphere the login page, we're facing the connecion reset issue with SQLState as null. If provide the details again in the page, everything is working on fine for some time. If we try after some time, again the same problem for the first time and when re-enter the user name and password, it is working fine for sometime.

This can cause a memory consumption problem. JDBC Thin driver does not http://stackoverflow.com/questions/27447193/hibernate-sql-error-17002-sqlstate-null-io-exception-connection-reset allocate memory when using VARCHAR2 output type. But JDBC OCI driver allocates memory for both CHAR and VARCHAR2 types. So, CPU load in OCI driver is higher than Thin driver. At previous releases, the solution to the problem was to invoke the Statement.setMaxFieldSize method. A better solution is to use OracleCallableStatement.registerOutParameter. Oracle encourages you always to call registerOutParameter (int paramIndex, int sqlType, int scale, int maxLength) on each CHAR or VARCHAR2 column. https://docs.oracle.com/database/121/JJDBC/apxtblsh.htm This method is defined in oracle.jdbc.OracleCallableStatement. Use the fourth argument, maxLength, to limit the memory consumption. This parameter tells the driver how many characters are necessary to store this column. The column is truncated if the character array cannot hold the column data. The third argument, scale, is ignored by the driver. Memory Leaks and Running Out of Cursors If you receive messages that you are running out of cursors or that you are running out of memory, make sure that all your Statement and ResultSet objects are explicitly closed. Oracle JDBC drivers do not have finalizer methods. They perform cleanup routines by using the close method of the ResultSet and Statement classes. If you do not explicitly close your result set and statement objects, significant memory leaks can occur. You could also run out of cursors in the database. Closing a statement releases the corresponding cursor in the database. Similarly, you must explicitly close Connection objects to avoid leaking and running out of cursors on the server-side. When you close the connection, the JDBC driver closes any open statement objects associated with it, thus releasing the cursor on the server-side.

REDISCOVERY To verify whether you are hitting this problem, verify whether the Oracle instance is configured for Multithreaded Server (MTS). If the Oracle instance is not configured for MTS, you are probably encountering a different problem. Otherwise, continue. Try forcing the JDBC connection to use a dedicated server instead of a shared server. This can be accomplished in several ways. For JDBC OCI or Thin, this can be done by reconfiguring the server for dedicated connections only. This approach, however, may not be feasible in many cases. In such cases, the following options apply: For JDBC OCI: 1) Add the (SERVER=DEDICATED) property to the TNS connect string stored in the tnsnames.ora file on the client. 2) Set the user_dedicated_server=ON in sqlnet.ora on the client. For JDBC Thin: You must specify a full name-value pair connect string (the same as it might appear in the tnsnames.ora file) instead of the short JDBC Thin syntax. For example, instead of "jdbc:oracle:thin:@host:port:sid" you would need to use a string of the form "jdbc:oracle:thin:@(DESCRIPTION=" + "(ADDRESS_LIST=" + "(ADDRESS=(PROTOCOL=TCP)" + "(HOST=host)" + = "(PORT=port)" + ")" + ")" + "(CONNECT_DATA=" + "(SERVICE_NAME=sid)" + "(SERVER=DEDICATED)" + ")" + ")" If the connection works fine after having made these changes, it is very likely that this is the problem you are encountering. In this case, one last test will help to verify this fact. Log into the remote host on which the Oracle instance is running and execute the appropriate command to determine what the server 'thinks' its hostname is (i.e. the name that was configured when the server was installed Vendor Code 17002 Network Adapter Sql Developer
