MRP0 - wait_for_log

Hello everyone,

Maybe someone of you have experienced the same problem I am. I've configured Data guard from a RAC database (2 nodes) to Standalone Database with an active duplicate enabling Real-time apply.

The problem is as follows:

1.- "MRP0 - wait_for_log" detected in Standby database, logs are not applied anymore:

PROCESS   STATUS          THREAD#  SEQUENCE#     BLOCK#     BLOCKS
