As Laozhang Said:
在Exadata中,同样可以借助IORM来控制flashCache和flashLog的使用,比如在如下的dbplan中,针对oltp和dss均打开了flashLog,而flashCache缺只对oltp有效。
CellCLI> alter iormplan -
> dbplan=((name=oltp, level=1, allocation=80, flashCache=on, flashLog=on),-
> (name=dss, level=1, allocation=20, limit=50, flashCache=off, flashLog=on),-
> (name=other, level=2, allocation=100, flashCache=off, flashLog=off))
IORMPLAN successfully altered
