• Oracle recommends the use of high redundancy disk groups for mission critical
applications. The location of the backup files depends on the backup method. To
reserve more space for the DATA disk group, choose external backups. This is
especially important when the RECO disk group is high redundancy. The following
table shows the backup options and settings.

• A valid time zone name is required for Oracle Exadata Database Machine
installation. Time zone data provided with Oracle Exadata Database Machine and
Oracle Linux comes from the zoneinfo database. A valid time zone name is
suitable as a value for the TZ environment variable consisting of form Area/
Location. For example, a valid entry is
America/New_York
. Invalid entries are EST,
EDT, UTC-5, and UTC-4.

3.1.2 Using Oracle Exadata Deployment Assistant on Systems with
Non-Default root Passwords
Starting with the November 2016 release, Oracle Exadata Deployment Assistant
supports deployment on Exadata environments that already have non-default root
passwords. You can perform the deployment without having to change the root
password back to the default. In earlier releases, OEDA expected the root password to
be the default on all the servers in an Exadata environment.
