IBM PureData System for Analytics, Version 7.1
IBM PureData System for Analytics, Version 7.1
The following table describes the commands that you can use to monitor and manage the IBM® Netezza® system. These commands are in the /nz/kit/bin directory on the Netezza host. A subset of these commands is also installed with the Netezza client kits and can be run from a remote client system, as described in Command locations.
To run these commands from the Netezza system, you must be able to log in as a valid Linux user on the Netezza system. Most users typically log in as the nz user. In addition, many commands require that you to specify a valid database user account and password; the database user might require special privileges, as described in Command privileges. Throughout this section, some command examples show the database user and password options on the command line, and some examples omit them with the assumption that the user and password were cached such as by using nzpassword.
