Answer 1

Hi
In step 1 : "Install SAP on DR site (including CI & DB)" -> With this step, I must install a new instance SAP with (CI + DB) in DR site as normally ? CI+DB must have a SID, hostname and instance number the same as Primary site ?
Ans-->  yes install DB+CI on one instance and it must have same SID,hostname(not necessary),instance number
step 3 : "enable force logging in primary site" -> I have not understand your comment, please guide clearly ?
Ans--> u need to implement force logging in primary database
sql> select force_logging from v$database;
sql>alter database force logging;
In step 4 : "From your primary site shutdown db and copy the datafiles to the DR site" -> With this step, before shutdown DB and copy datafile in Primary site to DR site, How do I do with the datafile was created in DR site at step 1 ( Must I delete them in DR site ?)
Ans-->do not copy the datafiles of primary to standy database. just take a full offline backup of primary database, then restore it on standby database(only restore do not open it), then configure oracle DG
In step 6 : "Create a backup controlfile" -> why create a backup controlfile while at step 1, we have a controlfile after a new instance SAP was created in DR site - I think If a new instance SAP was created in DR site, controlfile in DR site the same with Primary site (sorry if my thoughts are not true), please clearly
Ans--> u need to create a standby controlfile and it will be created from your primary database.
for your reference i am listing down the steps in serial order, first complete one then proceed to second and hopefully u will be able to configure Oracle GD
