Error description

  • missing condition in the define of syscat.sequences leads to
    duplicate entries
    

Local fix

  • Use the following query instead
    
    select
    a.seqschema, a.seqname, a.definer, a.definertype, a.owner,
    a.ownertype,
    a.seqid, a.seqtype, a.base_seqschema, a.base_seqname,
    a.increment, a.start,
    a.maxvalue, a.minvalue,
    case when a.lastassignedval + a.increment > a.maxvalue
    and a.increment > 0
    then case when a.cycle = 'Y' then a.minvalue else null end
    when a.lastassignedval + a.increment < a.minvalue
    and a.increment < 0
    then case when a.cycle = 'Y' then a.maxvalue else null end
    else coalesce(a.lastassignedval + a.increment, a.start) end,
    a.cycle, a.cache,
    a.order, a.datatypeid, a.sourcetypeid, a.create_time,
    a.alter_time, a.precision, a.origin, b.remarks
    from sysibm.syssequences as a left outer join
    sysibm.syscomments as b
    on a.seqid = b.objectid and b.objecttype = 'Q'
