SAP Solution Manager 7.1 Installation

Hello Masters

I'm starting the installation SAP Solution Manager 7.1 but I don't know wich medias are the correct.

I already downloaded the medias below:

51041939 ORACLE RDBMS 11.2.0.3 LINUX x86_64

51045452 SAP Solution Manager 7.1

51042607 SAP SOLMAN 7.1 SR1 Inst. Export

So I have some questions:

1) Is it the media SAP SOLMAN 7.1 SR1 Inst. Export the Installation Master DVD? If it is, why sapinst do not come with it?

2) I've downloaded sapinst separetely and ran it but I received an error saying that the files control.xml or product.catalog dont exist. There are no such files in the medias that I've downloaded.

Could you help me?

Regards
