XStream replication system parameters

Use these parameters to control the way that CDC Replication works with Oracle XStream.

mirror_on_ddl_operation
The mirror_on_ddl_operation parameter determines what action CDC Replication takes when it detects a DDL operation at a source table.
mirror_heartbeat_interval_seconds
Use this system parameter to specify the frequency in seconds for performing a heartbeat operation on the source database to keep it busy.
mirror_batch_interval_seconds
Use this system parameter to set the Oracle XStream batch processing interval in seconds.
mirror_idle_timeout_seconds
Use this system parameter to set the Oracle XStream idle timeout value.
mirror_update_low_watermark_seconds
Use this system parameter to set the frequency of updating the low watermark during replication, in seconds.
xstream_capture_checkpoint_retention_time_days
Use this system parameter to set the checkpoint retention time for Oracle XStream capture.
xstream_configuration_events
This property controls whether CDC Replication triggers events when making changes to XStream components.
xstream_capture_parameters
Use this parameter to define the way that CDC Replication configures Oracle XStream capture.
xstream_apply_parameters
Use this parameter to define Oracle XStream apply parameters that are associated with an XStream outbound server. CDC Replication uses the parameters to configure the XStream outbound server.
xstream_oldest_acceptable_build_timeout_hours
Use this parameter to define the maximum amount of time from which CDC Replication should initialize an Oracle XStream capture.
xstream_include_extra_capture_attributes
Use this parameter to determine what attributes CDC Replication configures to be supplied by Oracle XStream when it defines an Oracle XStream capture.
