10.1 Requirements for High Availability

The following are required for a high availability configuration:

  • Each computer has an independent instance of Oracle TimesTen.

  • Each computer has an odbc.ini file that contains a separate DSN for each instance of Oracle TimesTen. Each Oracle TimesTen DSN uses the client/server mode of connection.

  • A BI Server repository can point to one or more physical repositories, but one set of aggregates exists per physical data source. Each physical data source has its own connection pool.
