Checking Preinstall Requirements
The OUI automatically performs the following verifications (some steps are specific to the
Linux/Unix platform):

Checks for certified version of operating system software. For example, only the SuSE
SLES-7, Red Hat Advanced Server 2.1, and United Linux 1.0 platforms are supported
under Linux, and only Solaris 2.8 or higher is supported for Sun platforms. (Always verify
current certifications at
http://technet.oracle.com
.)

Checks to make sure 32-bit Oracle 10
g
software components are not installed to an Oracle
home directory with 64-bit Oracle 10
g
software and vice versa.

Verifies that all the required operating system patches are installed.

Checks for all the required kernel parameters.

Checks if the
DISPLAY
variable and X Server permissions are set.

Verifies sufficient swap space and temporary space are available.

Verifies that the Oracle home directory where the software being installed is either empty
or has the supported version of software components. Previous versions of Oracle were
allowed to install software to an Oracle home directory with a different software version,
but Oracle 10
g
does not allow this. It warns you if the software directory is not empty.
