You want to implement ASM for the existing database instances and define the following
parameters in the parameter file of the ASM instance.
DB_UNIQUE_NAME = +ASM
ASM_POWER_LIMIT = 1
ASM_DISKSTRING = ‘/dev/dsk/*s2′,’/dev/dsk/c1*’
ASM_DISKGROUPS = dgroupA, dgroupB
LARGE_POOL_SIZE = 8MB
While starting the ASM instance, you get the following error message:
ORA-15021: parameter “asm_diskstring” is not valid in RDBMS instance. and the instance
startup fails.
What causes the instance startup to fail?
A.
DB_NAME parameter should have been defined and set to ASM.
B.
ASM_DISKSTRING parameter should not contain any wildcard characters.
C.
ASM_DISKGROUPS cannot have two values.
D.
INSTANCE_TYPE parameter should have been defined and set to ASM.
E.
LARGE_POOL_SIZE should be set to a lower value.
F.
ASM_POWER_LIMIT should be set to a higher value.
