When the Oracle BI Server is running on Linux or UNIX, most data source connections are for query-only access.
The Administration Tool is used for importing objects and is a Windows-only tool. Because of this, data source connections for import must be set up on Windows.
Note that some data source connections on Linux and UNIX do support write operations for special functions, like data source connections for write-back, usage tracking, and annotations for Oracle Scorecard and Strategy Management.
When the Oracle BI Server is running on Linux or UNIX and you need to update database object settings (such as the database type) or connection pool settings, you can copy the repository file to a Windows computer, make the changes using the Administration Tool on Windows, and then copy the repository file back to the Linux or UNIX computer.
There are three types of data source connections on Linux and UNIX platforms:
Native data source gateway connections, such as OCI for Oracle Database or DB2 CLI for IBM DB2
ODBC connections using the DataDirect Connect ODBC drivers that are bundled with Oracle Business Intelligence
Native ODBC connections using external drivers, such as for Teradata data sources
Note that you can have a single repository that contains both DataDirect Connect ODBC connections and native ODBC connections. In this situation, both the native ODBC drivers and DataDirect ODBC drivers need to be managed by the same DataDirect ODBC driver manager. For example, the Teradata ODBC drivers include their required ODBC driver managers. When the Teradata ODBC driver is used with Oracle BI EE, the driver must be managed by the DataDirect ODBC driver manager bundled with Oracle BI EE.
