You can have multiple ldmd configuration files with various names. The names are case-sensitive (that is, Alpha and alpha are different names), so you can have configuration files that use the same word. The Oracle ILOM UI names are case-insensitive (but case-preserving). Thus, multiple configuration file names like Alpha and alpha cause confusion in the Oracle ILOM UI.
For example, if you type this command when there are multiple configuration file names, the UI hangs:
-> show /HOSTx/domain/configs
Workaround: Remove one of the case-matching ldmd configuration files. Then wait for the Oracle ILOM infrastructure to automatically restart the UI process.
