ORA-16801: redo transport-related property is inconsistent with database setting
Cause: The values of one or more redo transport-related configuration properties were inconsistent with database in-memory settings or server parameter file settings. This may happen by altering initialization parameters directly instead of altering property values using Data Guard broker.
Action: Query property the InconsistentLogXptProps on the primary database or check the Data Guard broker log to find which properties are set inconsistently. Reset these properties to make them consistent with the database settings. Alternatively, enable the database or the entire configuration to allow the configuration property settings to be propagated to to the initialization parameters.
