I made an installation of Oracle 11g recently and had started to set up
Data Guard when got some errors during configuration. Since the new
version of databases came with Automatic Diagnostic Repository (ADR)
I thought it might be useful and interesting to check if adrci can
provide some view of not only alert log but Data Guard log files as well.
Unfortunately I did not find such possibility but at least dr...log file
can be added to an incident package if it is generated.
I hope in future releases ADR will integrate Data Guard logs as well.
Have a good day!
