Preparing and executing queries and wor king with cursors This section shows the basic steps of preparing and executing a query and working with cursors. Every data store backup contains the information needed to restore the data store as it existed at a the backup point ; the time the backup began. To rename the owner of tables in a data store , use the ttMigrate utility.

See “Managing cache groups” regarding timesten odbc TimesTen functionality. Examples of when the round trip would be required: Connecting to a database using a connection string T imesTen applications require a Timesten odbc or a connection string be specified to connect to a database.

See “Connecting to a database using a connection string” for details.

INI file, TimesTen uses the first one in the file. In the Description field, enter an optional description for timesten odbc server.

Both attributes take a percentage value. These files are used internally by TimesTen for maintaining logs. Consider ing TimesTen features for access control TimesTen has features to control database access with object-level resolution for database objects such as tables, views, materialized views, timesten odbc, and synonyms. For example, you cannot use a symbolic link to refer to the database in one DSN and the actual path name in another DSN.

Temporary data includes locks, cursors, compiled commands, and other structures needed for command timesten odbc and query evaluation. Timesten odbc maximum is 99, seconds.

TimesTen ODBC Functions and Options

timesten odbc The permanent data partition can be timesten odbc in size, but it cannot be decreased. Specify data store attributes in your ODBC.

You can monitor oebc fragmentation in the data store by using the ttBlockInfo built-in procedure. Under some circumstances, a TimesTen database may develop memory fragmentation such that significant amounts of free memory are allocated to partially filled pages of existing tables.

Thread programming with TimesTen TimesTen supports multithreaded application access to data stores. Figure Data store Description of “Figure Data store”. This section includes the following topics: INI file This section includes the following topics: When timesten odbc do not specify any value for the DSN connection timesten odbc in the connection string.

timesten odbc Migrate and rebuild the standby database Reverse the active and standby roles Destroy and re-create the new standby The example in this section shows how to perform an online defragmentation with an active standby timesten odbc replication scheme where the active database is ttdb1 and the standby database is ttdb2.

The default prefetch value is a good setting timesten odbc most applications. Yo u can choose the desired mode timestten the DuplicateBindMode TimesTen general connection attribute. It can bind a different value for the occurrence. If there is a failure timesten odbc the active node, failover transfer to the new tiimesten original standby node occurs, and applications are automatically reconnected to the new active node.

For the SQL statement above, the two occurrences of a are considered timesten odbc be a single parameter, so cannot be bound separately:. In environments where threads are created and timesten odbc rapidly, better performance may be obtained by maintaining a pool of connections.

Each concurrent connection can have different values.

Odbd can result in an inability to allocate memory for other uses such as new pages for other tables due to a lack of free memory. See “Compiling and timesten odbc applications” for related information.

This is typically used timestsn DDL statements or for DML statements that timesten odbc execute only a few times and without bind parameters. A value that is smaller than the actual buffer size may result in spurious truncation warnings. Migrate timesfen data store between releases of Timesten odbc Timedten a data store between different hardware platforms Add rows of data to a table Take a snapshot timesten odbc a data store and then restore it Rename the owner of tables in a data store To migrate a data store between releases of TimesTenuse the ttMigrate utility.

Features for use with replic ation For applications that timesten odbc replication, you can improve performance by using parallel replicationwhich uses multiple threads acting in parallel to replicate and apply transactional changes to nodes in a replication scheme.
