DNS Name Resolution

This information is most relevant when running the product on Linux/Unix platforms

There are several components that perform Internet Protocol name resolution as part of their normal operation. The Prognosis Server converts server names to uppercase so whether the name resolution succeeds or not depends on whether the name look-up is performed in a case-sensitive way or not.

Name resolution by DNS is not case-sensitive. However, if nsswitch.conf allows fallback to a hosts file then the name resolution might be case-sensitive and the lookup might fail if the canonical name of the host is mixed or lowercase.

To enable smooth operation, ensure that the hosts file contains an uppercase alias for the Prognosis hostname.
