SCOPE = SPFILE
The change is applied in the server parameter file only. The effect is as follows:
■ For dynamic parameters, the change is effective at the next
startup and is persistent.
■ For static parameters, the behavior is the same as for dynamic
parameters. This is the only SCOPE specification allowed for
static parameters.
SCOPE = MEMORY
The change is applied in memory only. The effect is as follows:
■ For dynamic parameters, the effect is immediate, but it is not
persistent because the server parameter file is not updated.
■ For static parameters, this specification is not allowed.
SCOPE = BOTH
The change is applied in both the server parameter file and
memory. The effect is as follows:
■ For dynamic parameters, the effect is immediate and
persistent.
■ For static parameters, this specification is not allowed.
