The SharePlex internal tables shareplex_actid and shareplex_routes have one additional columns each in 8.6.3 which were missing.
The ora_setup was not run after SharePlex upgrade. This resulted in shareplex_actid missing the column CDB_CON_ID and shareplex_routes missing the column FLAG causing Capture and Read to show the above errors.
Shutdown SharePlex, run ora_setup so that the internal tables are updated and restart SharePlex.
