Verify OS and CRS installation standard

In Oracle world, we have utility called "OraChk" (earlier it was called RACCheck) to verify that RAC is built as per Oracle standards and best practices.

Is there similar utility or some reference SAP note that helps in this regard for Oracle on SAP?

I want to ensure that RHEL 5.x OS build and Oracle 11.2.0.3 CRS build is up to the SAP standard and there is no deviation.

Thanks,

Abhi
