oracle linux database installer can't find elfutils-libelf-devel-0.97 pdksh-5.2.14

If you run the validation it's ok

The problem is in the database/stage/cvu/cv/admin/cvu_config
configuration file

You can ignore or set CV_ASSUME_DISTID=
to OEL6 or higher.

make a backup and test before :)

Can ping from Oracle linux to an address but not to a name

In Oracle linux, we assigned 8.8.8.8 as dns, and we could ping 8.8.8.8, but can't ping to www.google.com in example.

We solved assigning the dns we used to assign to our microsoft windows computer.
