Problem

A user is trying to open a Relativity catalog, but is getting format errors within the designer tool. Why is that happening?

Resolution

As part of the process of creating a Relativity catalog, the file manager needs to be identified. For the majority of cases, this is the RM file handler as the data files are RM files. It is possible to configure Relativity to access MF files, so the file handler needs to be set to the MF file handler.

Once the catalog file handler has been set, not only are the data files accessed using the specified file handler, but the catalog is also created using that file handler. This means that if the MF file handler is used, the catalog is created in the Micro Focus format, not in the RM file format.

When the catalog is deployed, or the location is moved (eg moved from a development machine to a deployment server), the same version of the file handler needs to be present so that the catalog is correctly accessed.
