Re: Re[2]: max_failure and noreopen parameter in dataguard?

reopen is the interval in seconds between attempts to open, default 300 seconds.
max_failure is the number of attempts to reopen, default is nomax_failure meaning infinit attempts.
.
I think you need:
MAX_FAILURE=10 REOPEN=60
That will give you 10 attempts to reopen, with one minute between each attempt.
