Will updates statements applied to a Logical Standby DB update DBs accessed via DB Links

Hi,

What I like to know is whether updates statements applied to a Logical Standby Database
will update other databases accessed via Database Links.

We have

Primary DB - PrimA
External DB - ExtDB

our applications run on "PrimA" and they may
Scenario 1. update data in "ExtDB" using a DB Link.
Scenario 2. Update data in PrimA based on data stored in ExtDB accessed via a DB Link

We have created a Logical Standby Database from "PrimA" for reporting purposes called "DestB".

My query is based on what happens when SQL-APPLY applies SQL from "PrimA" to "DestB"

Scenario 1. "ExtDB" has already been updated by "PrimA" - will "DestB" try and update also ?

Howdy, Stranger!
