staging_store_can_run_independently

Use this system parameter to determine if subscriptions will exclusively use the CDC Replication staging store to accumulate change data or if they will be allowed to use independent log readers and log parsers to receive data directly from the database logs.

Versions supported—CDC Replication Engine for Oracle databases version 6.5 and later

Changes to this system parameter value will only take effect after the replication engine is restarted.

If you change the value from true to false, you will need to clear the staging store before starting replication.
