Customize the optional statements in the ADNR configuration file.
The optional debug_level statement determines how much log data is captured in the ADNR's log file.
Technically, the host_group and server_group statements are optional. They can be omitted to flush a name server of all ADNR-managed resource records. However, if you omit these statements, ADNR will not manage name servers for the sysplex until the ADNR configuration file is updated with host_group and server_group statements and the MODIFY REFRESH command is issued. When no host_group or server_group statements are configured, the ipaddrlist statement is also optional. For more information, see Flushing a zone.
The key statement defines the key file used in creating digital signatures, which is used when specifying transaction signatures (TSIGs) for zone updates and zone transfers. For more information about keys, see Authorizing dynamic updates and Authorizing zone transfers.
