Initial system setup and information
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.
- 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 nz user is the default Netezza system
administrator account. The Linux user
is named nz with a default password of
- 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.
