A factory-configured and installed
IBM® Netezza® system
includes the following components:
- A Netezza data
warehouse appliance with preinstalled Netezza software
- A preconfigured Linux operating
system (with Netezza modifications)
on one or both system hosts. Netezza high-availability
(HA) models have two hosts, while non-HA models have one host.
- A virtual server environment to run the Mantra® compliance application.
- Several preconfigured Linux users
and groups, which must not be modified or deleted.
- The nz user is the default Netezza system
administrator account. The Linux user
is named nz with a default password of nz.
The Netezza software
runs as this user, and you can access the system by using a command
shell or remote access software as the nz user.
- Netezza HA
systems also require a Linux user
(hacluster) and two Linux groups
(hacluster and haclient) that are added automatically to the host
during the Heartbeat RPM installation.
- The MantraVM service uses the mantravm user and mantravm group
that are automatically added to the host during the MantraVM installation.
- A Netezza database
user named admin (with a default password of password).
The admin user is the database super-user, and has full access to
all system functions and objects. You cannot delete the admin user.
You use the admin account to start creating user databases and other
database user groups and accounts to which you can assign appropriate
permissions and access.
- A preconfigured database group named public. All
database users are automatically placed in the group public and therefore
inherit all of its privileges. The group public has default access
privileges to selected system views, such as lists of available databases,
tables, and views. You cannot delete the group public.
Netezza Support
and Sales representatives work with you to install and initially configure
the Netezza in
your customer environment. Typically, the initial rollout consists
of installing the system in your data center, and then configuring
the system host name and IP address to connect the system to your
network and make it accessible to users. They also work with you to
do initial studies of the system usage and query performance, and
might advocate other configuration settings or administration ideas
to improve the performance of and access to the Netezza for
your users.
