Restore the DB, showing DB in use

Hi Folks,

Recently I was facing some issue while restoring AX database, whenever I try to restore the Transactional DB its show error "DB is use" while actually this DB is not used anywhere. Than I try to take take the database offline, But again there was one other issue.
Same issue again DB offline taking very long time.
I tried below steps and this worked for me. :)
Step 1: Try to run below two queries in same given sequence.

i. ALTER DATABASE <DBNAME> SET OFFLINE WITH ROLLBACK IMMEDIATE

ii. ALTER DATABASE <DBNAME> SET Offline

Step 2: Now try to take offline manually.

Step 3: Restore the DB.
Step 4: Some time after doing restoration/backup DB will not work.
Than u need to roll back above query operation
ALTER DATABASE <DBNAME> SET online WITH ROLLBACK IMMEDIATE
ALTER DATABASE <DBNAME> SET online.
