Netezza: Multiple history databases

(Q) Can we have multiple history databases created?

An history database captures information about user activity such as

  • Queries
  • Query plans
  • Table access
  • column access
  • session creation
  • and failed authentication.

Trust me, your auditors love this information 🙂

The above information is stored in a database that you have created using nzhistcreatedb command.

Once you create database(s), you have to create an history configuration using “CREATE HISTORY CONFIGURATION” to decide on what history to collect and at what frequency and what database to load this information.

We can create N number of history databases but only one can be active at any time. Whichever history configuration is active, that decides the current history database.
