Oracle ASM : Alter asm_diskstring when ASM Instance is Down,

oracleoracle-12coracle-asm

I am beginner for Oracle ASM
I know we can alter asm_diskstring with following ways

  1. SqlPlus
  2. ASMCA

but these requires +ASM to be UP and running. Is there way to set asm_diskstring when +ASM instance is down ?

Thanks,

Best Answer

You can create pfile to set asm_diskstring.

$ vi asmpfile.ora
instance_type=asm
asm_diskstring=path_to_asmdisks

Then can start asm instance using this pfile and later can create spfile from pfile.
