I am running TOP and I am seeing ora_tt00 backroom process at the top of list
consistently (sorting by CPU), I mean it is at the top steadily. I
understand that this has something to do with Redo Transport but I am not
sure in what regards and if there is anything I can or should do about it. I
have 2 databases on this same server both running Data Guard but this process
is showing for only one of the databases. I think both databases are kind of
equal on activity.
Anything else I should be looking at?
Thanks,
Jeff
