What Happens
Each time the name manager or name exporter opens a database file, it makes the
following checks on the file:
File code. The DNS configuration file must have file code 849 and database files
must have file code 850.
Device type. The file must be a disk file.
File type. The file must be key-sequenced.
Key offset and length. The file must have key offset 0; the key length varies by file.
Record length. The maximum record length for the file must be greater than or
equal to the longest record that can be stored in the file.
The ZDNS-EVT-ILL-FILE message is generated if any of these checks fail. If the DNS
configuration file is invalid; the process issuing the event message calls a process
termination procedure such as ABEND.
When processing the START DNS command, DNSCOM performs each of the checks
listed above; if any of the checks fail, DNSCOM issues an error message, and DNS is
not started. If this event message is issued, then the file indicated in the message must
have been altered or replaced since DNS was last started (or DNS was not started
using DNSCOM).
Recommended Action
If the message refers to the DNS configuration file, that file may be rebuilt using the
INITIALIZE DNS, DNSCONFONLY command.
If the message refers to another database file, either replace the incorrect file using FUP
or use the ALTER DNSFILE command to refer to the correct file.
