i m trying dataguard in rac.first i am just creating a standby database by just making tnsentries and changing pfile necessary parameters for standby.
is enabling of force logging a necessary parameter
as i tried without enabling force logging.is it a mandatory step
FORCE LOGGING isn't mandatory but highly recommended. If you don't set FORCE LOGGING, you need to have administrative procedures that track the usage / execution of NOLOGGING OPERATIONS and then ensure that the target tablespaces are backed up from production and restored to the standby.
