Error description

  • When an IDR for Oracle instance is used for both source and
target, and when a refresh using fastload is started on this
IDR instance while the subscription using this IDR instance as
the source is already running in Mirror Continuous, a core dump
will take place

Local fix

  • 1. set 'refresh_allow_fast_loader=false' at the target datastore
level in MC and restart the instance.

OR

2. Do not run any Mirror Continuous for this instance as a
source when refresh is taking place
