Installing WAS 640 for Oracle DB on solaris

Hi.

I'm trying to install WAS 640 (NW 04 SR1) on solaris with oracle as the

DB. However, the installation program asks for the location of rdbms

dvd/cds. No oracle dvd/cds were provided with the NW04 SR1 package.

Please advise as to which dvds the installer is looking for.

I also tried installing oracle 9i, created a database and then ran the sap installer in custom installation mode and deselected "create new database". However the SAP install threw an error saying that it could

not find the necessary .ora files in the <ORACLE_HOME> directory specified.

Please tell me whether i'm looking in the right direction. Is there a particular set of configurations to be performed to enable SAP to run with oracle?
