i have just setup a brand new dataguard on my 18.10 instance(s). My show configuration and all databases show a successful configuration and i am running perfectly in max performance mode.
I tried converting the configuration to maxavailability mode first in cloud control. The process completes, but it hangs on the 'Processing Completed" screen. The protection mode does not get changed.
I shut everything down and tried to change it manually in DGMGRL only to see that when i run the
edit database <standby> set property LogXptMode=SYNC
to change it to sync mode it fails immediately with a
"Error: ORA-16713: The Oracle Data Guard broker command timed out."
i have bounced everything i can think of and searched the support site for solutions with no luck. I have done this procedure many many times and never had this issue. I tired updating the OperationTimeout for the configuration as one article suggested and that did nothing.
I am out of ideas..
