** Myself
## Pre Step
#1) Install oracle software (oracle standard or enterprise edition)
#2) Assigne disk same as production system
#3) Transfer backup offline to standby host (not export or datapump) to same as location production system
#4) Create standby control file from production system and transfer to standby host same location of control file (same step as create standby database or dataguard)
#5) Set rcp or scp for trust file transfer
#6) Adjust Dynamic ENV and Execute binary ENV for you want
#7) Put shell script to standby database host (DR) ,Please see below
#8) Sheduling this shell for executing by crontab every 1 or 5 mins (script will be transfer difference archivlog)
##Concept for processing
#1) Find archive directory
#2) Find max sequence on standby db
#3) Find file transfer from primary db (newer archivelog)
#4) List file name transfer to standby db
#5) Transfer files from primary to standby db
#6) Recovery all transfer file (standby database will be apply new archivelog file from source system)
