In what is surely not a coincidence given Oracle's announcement of Symantec a certified Oracle Enterprise Linux partner, Red Hat has announced that SAP has certified its applications on Red Hat Enterprise Linux 5.
In fact, Red Hat has also announced that Oracle has completed certification of Oracle 10g Release 2 on RHEL 5.
According to Red Hat, after four months of product availability, nearly 400 applications are now certified, which puts into perspective somewhat the ISV support for Oracle Enterprise Linux, when you consider RHEL 5 launched a full 5 months after OEL.
A full list of RHEL 5 compatible software can be found here, while a list of Oracle endorsements (which doesn't necessarily mean certifications) is here.
