        public abstract void setAutoCommit(boolean autoCommit)
                            throws java.sql.SQLException
        Sets the auto-commit mode. If the connection is in auto-commit mode, then all of its SQL statements are executed and committed as individual transactions. Otherwise, its SQL statements are grouped into transactions that are terminated by either a commit or rollback.

        By default, the connection is in auto-commit mode. The commit occurs when the statement execution completes or the next statement execute occurs, whichever comes first. In the case of statements returning a result set, the statement execution completes when the last row of the result set has been retrieved or the result set has been closed. In advanced cases, a single statement may return multiple results as well as output parameter values. Here the commit occurs when all results and output parameter values have been retrieved.

        The auto-commit mode is always false when the connection is part of a distributed transaction. See AS400JDBCXAResource for more information.

        Specified by:
        setAutoCommit in interface java.sql.Connection
        Parameters:
        autoCommit - true to turn on auto-commit mode, false to turn it off.

                          throws java.sql.SQLException
        Sets the read-only mode. This will provide read-only access to the database. Read-only mode can be useful by enabling certain database optimizations. If the caller specified "read only" or "read call" for the "access" property, then the read-only mode cannot be set to false. The read-only mode cannot be changed while in the middle of a transaction.

        This method can not be called when the connection is part of a distributed transaction. See AS400JDBCXAResource for more information.

                                      throws java.sql.SQLException
        Sets the transaction isolation level. The transaction isolation level cannot be changed while in the middle of a transaction.

        JDBC and DB2 for IBM i use different terminology for transaction isolation levels. The following table provides a terminology mapping:

        IBM i isolation levelJDBC transaction isolation level
        *CHG TRANSACTION_READ_UNCOMMITTED
        *CS TRANSACTION_READ_COMMITTED
        *ALL TRANSACTION_READ_REPEATABLE_READ
        *RR TRANSACTION_SERIALIZABLE
        Specified by:
        setTransactionIsolation in interface java.sql.Connection
        Parameters:
        level - The transaction isolation level. Possible values are:
        • TRANSACTION_READ_UNCOMMITTED
        • TRANSACTION_READ_COMMITTED
        • TRANSACTION_REPEATABLE_READ
        • TRANSACTION_SERIALIZABLE
        Throws:
        java.sql.SQLException - If the connection is not open, the input level is not valid or unsupported, or a transaction is active.

      • setTypeMap

        public abstract void setTypeMap(java.util.Map typeMap)
                         throws java.sql.SQLException
        Sets the type map to be used for distinct and structured types.

        Note: Distinct types are supported by DB2 for IBM i, but are not externalized by the IBM Toolbox for Java JDBC driver. In other words, distinct types behave as if they are the underlying type. Structured types are not supported by DB2 for IBM i. Consequently, this driver does not support the type map.

        Specified by:
        setTypeMap in interface java.sql.Connection
        Parameters:
        typeMap - The type map.
        Throws:
        java.sql.SQLException - This exception is always thrown.

      • toString

                 java.lang.String value)
                            throws java.sql.SQLException
        Sets the value of the client info property specified by name to the value specified by value.

        Applications may use the DatabaseMetaData.getClientInfoProperties method to determine the client info properties supported by the driver and the maximum length that may be specified for each property.

        The driver stores the value specified in a suitable location in the database. For example in a special register, session parameter, or system table column. For efficiency the driver may defer setting the value in the database until the next time a statement is executed or prepared. Other than storing the client information in the appropriate place in the database, these methods shall not alter the behavior of the connection in anyway. The values supplied to these methods are used for accounting, diagnostics and debugging purposes only.

        The driver shall generate a warning if the client info name specified is not recognized by the driver.

        If the value specified to this method is greater than the maximum length for the property the driver may either truncate the value and generate a warning or generate a SQLException. If the driver generates a SQLException, the value specified was not set on the connection.

        The following client info properties are supported in Toobox for Java.

        • ApplicationName - The name of the application currently utilizing the connection
        • ClientUser - The name of the user that the application using the connection is performing work for. This may not be the same as the user name that was used in establishing the connection.
        • ClientHostname - The hostname of the computer the application using the connection is running on.
        • ClientAccounting - Client accounting information.
        • ClientProgramID - The client program identification.

        Specified by:
        setClientInfo in interface java.sql.Connection
        Parameters:
        name - The name of the client info property to set
        value - The value to set the client info property to. If the value is null, the current value of the specified property is cleared.

        //JDBC40DOC * @throws SQLClientInfoException if the database returns an error while //JDBC40DOC * setting the client info value on the database server.

        Throws:
        java.sql.SQLException

      • setClientInfo

        public abstract void setClientInfo(java.util.Properties properties)
                            throws java.sql.SQLException
        Sets the value of the connection's client info properties. The Properties object contains the names and values of the client info properties to be set. The set of client info properties contained in the properties list replaces the current set of client info properties on the connection. If a property that is currently set on the connection is not present in the properties list, that property is cleared. Specifying an empty properties list will clear all of the properties on the connection. See setClientInfo (String, String) for more information.

        If an error occurs in setting any of the client info properties, a ClientInfoException is thrown. The ClientInfoException contains information indicating which client info properties were not set. The state of the client information is unknown because some databases do not allow multiple client info properties to be set atomically. For those databases, one or more properties may have been set before the error occurred.

        The following client info properties are supported in Toobox for Java.

        • ApplicationName - The name of the application currently utilizing the connection
        • ClientUser - The name of the user that the application using the connection is performing work for. This may not be the same as the user name that was used in establishing the connection.
        • ClientHostname - The hostname of the computer the application using the connection is running on.
        • ClientAccounting - Client accounting information.
        • ClientProgramID - The client program identification.
        Specified by:
        setClientInfo in interface java.sql.Connection
        Parameters:
        properties - the list of client info properties to set //JDBC40DOC * @throws SQLClientInfoException If there is a problem with the Client Info. //JDBC40DOC * if the database returns an error while setting the //JDBC40DOC * clientInfo values on the database

      • setNetworkTimeout

        public abstract void setNetworkTimeout(int timeout)
                                throws java.sql.SQLException
        Sets the maximum period a Connection or objects created from the Connection will wait for the database to reply to any one request. If any request remains unanswered, the waiting method will return with a SQLException, and the Connection or objects created from the Connection will be marked as closed. Any subsequent use of the objects, with the exception of the close, isClosed or Connection.isValid methods, will result in a SQLException.

        In the JTOpen JDBC driver, this is implemented by setting the SoTimeout of the underlying socket.

        Currently, setting the network timeout is only supported when the "thread used" property is false.

        When the driver determines that the setNetworkTimeout timeout value has expired, the JDBC driver marks the connection closed and releases any resources held by the connection.

        This method checks to see that there is an SQLPermission object before allowing the method to proceed. If a SecurityManager exists and its checkPermission method denies calling setNetworkTimeout, this method throws a java.lang.SecurityException.

        Parameters:
        timeout - - The time in milliseconds to wait for the database operation to complete. If the JDBC driver does not support milliseconds, the JDBC driver will round the value up to the nearest second. If the timeout period expires before the operation completes, a SQLException will be thrown. A value of 0 indicates that there is not timeout for database operations.
        Throws:
        java.sql.SQLException - If a database error occurs.
        java.sql.SQLException - - if a database access error occurs, this method is called on a closed connection, or the value specified for seconds is less than 0.
        java.lang.SecurityException - - if a security manager exists and its checkPermission method denies calling setNetworkTimeout.

        public abstract int getNetworkTimeout()
                               throws java.sql.SQLException
        Retrieves the number of milliseconds the driver will wait for a database request to complete. If the limit is exceeded, a SQLException is thrown.
        Returns:
        The current timeout limit in milliseconds; zero means there is no limit
        Throws:
        java.sql.SQLException - - if a database access error occurs or this method is called on a closed Connection

      • setSchema

        public abstract void setSchema(java.lang.String schema)
                        throws java.sql.SQLException
        Sets the given schema name to access.

        Calling setSchema has no effect on previously created or prepared Statement objects. For the toolbox driver, the DBMS prepare operation takes place immediately when the Connection method prepareStatement or prepareCall is invoked. For maximum portability, setSchema should be called before a Statement is created or prepared.

        Parameters:
        schema - The name of the schema to use for the connection
        Throws:
        java.sql.SQLException - If a database access error occurs or this method is called on a closed connection
