Oracle Database from File system to +ASM Migration ..

Oracle Database from File system to +ASM Migration ..

File system to +ASM


For this demonstration I am Creating new database 

Create database . 

create database vihd
logfile   group 1 ('/u01/app/oracle/oradata/vihd/redo1.log') size 10M,
          group 2 ('/u01/app/oracle/oradata/vihd/redo2.log') size 10M,
          group 3 ('/u01/app/oracle/oradata/vihd/redo3.log') size 10M
