The figure shows two computers: the first computer has Identity Management 9.0.2 on it. The Identity Management is associated with a Metadata Repository 9.0.2. This metadata repository is used for identity management and product metadata. Step 1 is associated with the first computer: step 1 is to install 9.0.2 Oracle9iAS Infrastructure.

Step 2 is to run procedures documented in the text.

The second computer contains a middle tier 10g (9.0.4). This middle tier uses the product metadata from the 9.0.2 metadata repository on the first computer. Step 3 is to install the 10g (9.0.4) middle tier on the second computer.
