OracleDriver (Oracle Database JDBC API Reference)

Jdbc Driver Connection Url

Two keys differing in case only are considered conflicting, and there are no guarantees on which one will be used. Sets the default escape processing behavior for Statement objects. Alternatively, you can use the forName method of the java. Any property from the list can be specified.

For optimal connection performance, you should set the portNumber when you connect to a named instance. The driver will call setFetchSize n with this value on all newly-created Statements. The class must implement com.

This method is preferable because it allows you to make the driver registration configurable and portable. Should the driver cache the parsing stage of CallableStatements. When using loadbalancing or failover, the number of times the driver should cycle through available hosts, voodoo 2 driver windows 7 attempting to connect.

Connection Examples

Driver interface, as is the case with OracleDriver. Should the driver throw java. If no instance name or port number property is specified, a connection to the default instance is created. If the database is not specified, the connection is made with no default database.

While it is not possible to write host sublists recursively, a host list may contain host sublists as its member hosts. The useConfigs connection option is convenient shorthand for specifying combinations of options for particular scenarios. Include a current Java thread dump in exception messages when deadlock exceptions are detected?

How long should the driver wait, when failed over, before attempting to reconnect to the primary host? Should the driver refer to the internal values of autocommit and transaction isolation that are set by Connection. Assumes the configured user has permissions to create databases.

The type of the object returned is java. However, if you forget, Java's garbage collector will close the connection when it cleans up stale objects. The host and the port are identified by the keys host and port. Connecting with DataSource Objects.

Sample JDBC driver connection URL formats

If not specified, live management of replication connections is disabled. Changes in Connection Properties. Should the driver issue appropriate statements to implicitly set the transaction access mode on server side when Connection. Used when time zone from server doesn't map to Java time zone.

Maximum allowed packet size to send to server. Caches client's default time zone. As a side effect, obtaining the statement's generated keys information will return a list where normally it wouldn't. For user name and password values, use the connection property collections. Should the driver use Unicode character encodings when handling strings?

After you've loaded the driver, you can establish a connection using the DriverManager. Relying on the garbage collection, especially in database programming, is a very poor programming practice.

Connection URL Sample - SQL Server

The authentication plugins or mechanisms listed will not be used for authentication which will fail if it requires one of them. Although the previous example uses a username and password in the connection string, you should use integrated security as it is more secure.

If autoReconnect is set to true, should the driver attempt reconnections at the end of every transaction? Ignore non-transactional table warning for rollback? Properties and Descriptions useUnicode Should the driver use Unicode character encodings when handling strings? When auto-commit is enabled, the number of statements which should be executed before triggering load-balancing to rebalance.

Number of queries to issue before falling back to the primary host when failed over when using multi-host failover. High-load environments might want to consider disabling this functionality. It won't prevent failures when switching to slaves i. The comparison is done using Class. Each host in the list can be specified in any of the three ways described in Single host above.

This will avoid a round trip to the server to determine the port number. Inside a host sublist, no host can have user credentials in the format, but individual host can have user credentials specified in the key format. Also overrides the characterEncoding with those corresponding to character set of this collation.

Each instance is identified by a specific name. The regex must follow the patterns used for the java. This interface is preferred over DriverManager because it allows details about the underlying data source to be transparent to your application.
