you could used mv, but you may want to used cp instead, just because you may have to fall back, if your instance won't startup, like when it happend to me. this way, you can undo the init.ora and see where it went wrong.
This is Rohit from India.See ur configuration of control file placement is not correct.In order to protect ur database from crash u have to place ur controlfile on different disks.Because if ur disk containg controlfile crashes then u cant mount ur database.In such case u have to restore ur database to the last backup of ur controlfile.
In order to move ur controlile to different disks,first shutdown ur database.
SVRMGR > SHUTDOWN IMMEDIATE/NORMAL
Dont shutdown ur database using abort option.
Then,copy ur existing controlfile to other disks using ur operating system commands.
Then in init.ora parameter file,edit ur CONTROL_FILES parameter.Include all ur controlfile paths
Then save the file and then start the database.If u keep ur controlfiles in different disks,then ur database becomes riskfree of a crash or a controlfile not found.
this concept is known as mirroring of Controlfile and is recommended by OFA.If u have an any doubts ,please be free to write to me at email@example.com
Always shutdown yr database normally i.e shutdown immediate or shutdown normal. This ensures that all yr control files are up to date.
Next copy yr control files to their respective place/diretories.
Change the control_files parameters in init.ora to the new location.
Startup the database.
