Migration from Oracle ASM to Exadata

[Former Member]

Hi,

  Our customer has ordered for Oracle exadata HW for the Test and Production SAP instances.

However, since the delivery of these HW is delayed they have provided us normal Linux servers running Oracle ASM.

So currently SAP instances are installed with SAP instance on RHEL 5 and Oracle instance on ASM(Oracle Linux 5).

Oracle Db version is 11.2.0.2

Whenever we get the final HW we will need to migrate this setup like -

SAP instance on RHEL 5.x and Oracle instance on Exadata.

My question is -

what are the options do we have for this migration ?

Does this have to be performed using O2O methods mentioned in the Exadata best practice guides.

Since our datafiles are already installed on ASM disk groups +DATA, +RECO, +ARCH is it possible for us to move the datafiles using any other method.

Thanx for your replies

Hi,

Per the guides are 4 methods.

O2O and OOO are Oracle specific methods and payable (as far as I know)

But you can do the migration using RMAN Duplicate DB and also RMAN Transportable tablespaces.

I

I think they are explained on the ASM migration Guide. they are valid even when you are already ASM
