Below the url to download
OBIEE Patch 126.96.36.199.2 BP1 is available for download from Oracle Support site (http://support.oracle.com or http://supporthtml.oracle.com ).
If it helps mark as correct.
If this is related to client side implementation then reach out your client to get Support Identifier. Software we can download with out it but not patches and other.
If it is personal use then you may not get it.
Hope this helps
