The ORACLE_CAPTURE_TYPE statement specifies that the CDC type to use for the PowerExchange installation. The only available type is PowerExchange Express CDC for Oracle.
The ORACLE_CAPTURE_TYPE value must be consistent with the ORAD type of CAPI_CONNECTION statement that is defined on the system that initiates the connection to the Oracle system for change capture.
Linux, UNIX, and Windows
  • D
    . PowerExchange uses Express CDC for Oracle and the ORAD CAPI_CONNECTION statement.
No default value is provided. The only valid value is D.
  • PowerExchange Express CDC for Oracle handles all character columns as variable length columns. This behavior affects PowerExchange column-level processing and the view of the CDC extraction map that is imported into PowerCenter. All systems that are involved in Oracle change capture processing must be aware of the Oracle CDC type that is in use.
    On the PowerExchange system where the ORAD CAPI_CONNECTION statements are defined, the CAPI_CONNECTION type implicitly defines the CDC type, and the ORACLE_CAPTURE_TYPE statement is optional. However, if other systems are involved in CDC processing, for example, because you run a separate PowerExchange Listener or use offload processing, you can define the ORACLE_CAPTURE_TYPE statement in the dbmover.cfg file on each system.
  • For the ORAD CAPI_CONNECTION statement, the ORACLE_CAPTURE_TYPE value must be D. Otherwise, PowerExchange issues an error message and ends abnormally.
