Timesten Odbc Drivers

These requests timesten odbc serialized by TimesTen, although the application may require additional serialization of its own. Include file Description timesten. This section discusses the TimesTen implementation of automatic client failover as it applies to application developers, king cobra l4v driver covering the following topics.

The TimesTen binding mechanism early binding differs from that of Oracle Database late binding. This function takes care of any custom actions you want to occur in a failover situation. Sizes of attribute values apply to values of connection and statement attributes, either passed or returned. This is relevant only for client connections.

Using additional TimesTen data management features

All tracks are read, transmitted and applied in parallel. Automatic client failover is for use in High Availability scenarios with a TimesTen active standby pair replication configuration.

If there is a failure of the active node, failover transfer to the new active original standby node occurs, and applications are automatically reconnected to the new active node. Before statement execution, points to the buffer where the application places the parameter value to be passed to the application. Rowids can be represented in either binary or character format.

Returns a bit mask indicating platform information. Deleted rows are deleted on commit full level. Row value constructor expressions not supported.

It is up to the application to manage the data pointed to by the foCtx setting. Managing TimesTen data This section provides detailed information on working with data in a TimesTen database.

Allocated from heap, no limit on concurrency. The options are defined in the timesten.

First connection attributes are set when the database is first loaded, and persist for all connections. Environment objects are allocated from heap. Example Connect and disconnect complete program This example contains a complete program that creates, connects to, and disconnects from a database. Scrollable cursors not supported.



Pointer to a buffer for the data of the parameter. Catalog names as qualifiers not supported. The temporary data partition is created when a data store is loaded into memory and is destroyed when it is unloaded. Subsequent occurrences of the parameter name are not given their own position numbers.

It is required in the data structure due to driver manager implementation details, in case you are using a driver manager. Left outer joins supported. String scalar functions not supported. Another piecewise approach, using callback functions, is supported by Oracle Database but not by TimesTen. Generally, a higher value may result in better performance for larger result sets, at the expense of slightly higher resource use.

An operation running on an hstmt on timesten odbc thread. Every connection to the database is timesten odbc. The application may load several drivers and access each driver independently. Because the callback function executes asynchronously to the main thread of your application, it should generally perform only simple tasks, such as setting flags that are polled by the application. Maximum length of the rgbValue buffer, in bytes.

Wor king with rowids Each row in a database table has a unique identifier known as its rowid. Because this is a general connection attribute, different connections to the same database can use different values.

Managing TimesTen dataTimesTen ODBC Support

This function is called when the attempt to connect to the new active original standby node begins, and again after the attempt to connect is complete. No specific limit to number of active concurrent statements in asynchronous mode. Sizes of option or attribute values apply to values of connection options, statement options, column attributes, or driver and data source information, either passed or returned.

Binding is based on the position of the first occurrence of a parameter name. If the active node fails, the standby node becomes the new active node and then notifies the client of the failover. Commands are not shared with any other connection.

Daemon connections limited to this value. Asynchronous mode not supported. It can bind a different value for the occurrence.

Inner table right table in a left outer join or left table in a right outer join can also be used in an inner join. Global temporary tables can be created full level. The recovered database reflects the state of all durably committed transactions and possibly some transactions that were committed non-durably.

An operation running on an hstmt on another thread. There are several things to consider when choosing a character set for your database. The user name and password are used as is.

Transactions are serializable. Datetime scalar functions not supported. Pointer to driver descriptor handle.

It is also advisable to link your applications dynamically rather than statically. If a failover has already occurred and the client is already connected to the new active node, the next failover request results in an attempt to reconnect to the original active node. It can leave the parameter occurrence unbound, in which case it takes the same value as the first occurrence. This example contains a complete program that creates, connects to, and disconnects from a database. Con necting to and disconnecting from a database This section provides examples of connecting to and disconnecting from the database.
