Enable and disable security commands

This section explains how to enable or disable the advanced security commands and features.

The advanced security features are enabled by default on Netezza® systems. However, if you run a command that is described in this document and the command fails with the message ERROR: <command> is not currently supported, you must enable the features.

To enable or disable the features, you must log in to the IBM® Netezza system host, set the history configuration to QUERY or NONE and edit the postgresql.conf file. After you specify the configuration setting, save the file and restart the system (nzstop and nzstart) for the settings to take effect.
