pfile:
+ASM.__oracle_base='/oracle/database/u01/app/oracle'#ORACLE_BASE set from in memory value*.asm_power_limit=1*.diagnostic_dest='/oracle/database/u01/app/oracle'*.instance_type='asm'*.large_pool_size=12M*.remote_login_passwordfile='EXCLUSIVE'

+ASM.__oracle_base='/oracle/database/u01/app/oracle'
*.asm_power_limit=1
*.diagnostic_dest='/oracle/database/u01/app/oracle'
*.instance_type='asm'
