replicate before data for oracle lob columns or have the option to turn it off/on if you want
we've been made aware that your it is a limitation where lob columns don't get replicated with before data in qlik which technically brings data integrity into question and or kind of misses the point of change data capture.
we think this feature should be added as it works everywhere but oracle or at least have an option for you to turn this off or on if performance is an issue.
