In a Distributed SpectroSERVER (DSS) environment it is a requirement that all the catalogs are the same on all the SpectroSERVERs.
If they become out of sync you may see the following error:
"Two or more of the Spectrum catalogs in the DSS are in conflict'.
There is "More Information" link which provides more information as "Conflict have been encountered in the device identification settings within the DSS environment.
These conflicts exist because two or more of Spectrum catalogs are different.
Conflicts of this type may have been introduced by changing a modeling catalog using MTE or by failing to apply custom catalog work to all SpectroSERVERs in the DSS.
All conflicts must be resolved in order to use the identification tab."
Release: 10.x / 21.x
