Should remote systems attempt exports between times (A) and (B), ZDNS-EVT-
IMPORT-REJECTED event messages are generated for each such system. These event
messages may be safely ignored. The ZDNS-EVT-IMPORT-REJECTED message
should be selected by filters that are forwarding event messages to human operators to
guard against the possibility that the ALLOWIMPORTS attribute has been
inadvertently left in the OFF state.
Logical Database Reload The occurrence of a ZDNS-EVT-DATABASE-ERROR message and some instances of a
ZDNS-EVT-TYPE-ERROR message necessitate the rebuilding of the DNS database on
a node. This is accomplished using the following steps:
1. With DNS in the running state, execute the following command:
INFO/OUT RELOAD/ * , OBEYFORM
This creates a copy of the DNS database in OBEY file format in the volume and
subvolume set by a prior CMDVOL command. If the OBEY file already exists,
DNSCOM appends to it (which may not be what you intend). The CMDVOL
command and OBEY files are described in the Distributed Name Service (DNS)
Management Operations Manual.
2. Make any changes necessary to the edit files created in step 1. In particular, it is a
good idea to modify the file DNS to SET ALLOWIMPORTS OFF.
3. Execute the following command:
DNS /IN RELOAD/
For C00 systems, replace the command in step 1 with the following sequence of
commands. Steps 2 and 3 are the same for C-series systems.
INFO/OUT FILES/ DNSFILE * , OBEYFORM
INFO/OUT PROCS/ DNSPROCESS * , OBEYFORM
INFO/OUT DNS/ DNS , OBEYFORM
INFO/OUT DOMS/ DNSDOMAIN * , OBEYFORM
