We try to install OSM 7.0. But as per installation guide, we need to have database installation parameter O7_DICTIONARY_ACCESSIBILITY=TRUE. Currently our DB pointing to O7_DICTIONARY_ACCESSIBILITY=FALSE.
Is it mandatory to change the value. why do need to change this parameter. Any specific reason ?
Yes it is necessary to change O7_DICTIONARY_ACCESSIBILITY=TRUE cause this feature allows OSM to function for any localization. Since localization is optional but OSM installation have been designed as such that you cannot skip this step.
