ALL_STREAMS_SCHEMA_RULES displays information about several types of schema rules.

ALL_STREAMS_SCHEMA_RULES displays information about these types of schema rules:

Schema rules created for the capture processes that enqueue the captured changes into queues accessible to the current user
Schema rules created for the propagations that have a source queue accessible to the current user

This view does not contain information about rules created using the DBMS_RULE_ADM package.
