Active server database

The active server database contains zone and host information, including some zone properties, such as start of authority (SOA) information, and through host properties, such as mail exchanger (MX) information, which might be useful in tracking down problems.

Domain Name System (DNS) allows you to view a dump of the authoritative data, cache data, and hints data for a server instance. The dump includes the information from all of the server's primary and secondary zones (forward and reverse mapping zones), as well as information that the server has obtained from queries.

You can view the active server database dump using iSeries™ Navigator. If you need to save a copy of the files, the database dump file name is NAMED_DUMP.DB in your iSeries directory path: Integrated File System/Root/QIBM/UserData/OS400/DNS/<server instance>, where "<server instance>" is the name of the DNS server instance. More information about the active server database is available in the DNS online help topic Understanding the DNS server database dump.

To access the active server database dump, follow these steps:

  1. In iSeries Navigator, expand your iSeries server > Network > Servers > DNS.
  2. In the right pane, right-click your DNS server and select Configuration.
  3. In the DNS configuration window, select View > Active Server Database.
