DboSession -this $lSession
set lDesignsIter [$lSession NewDesignsIter $lStatus]
set lDesign [$lDesignsIter NextDesign $lStatus]
set lNullObj NULL

set oldLibName [DboTclHelper_sMakeCString "E:\\PROJECT_WORKLIB.OLB"]
set newLibName [DboTclHelper_sMakeCString "E:\\MCU_PARTS_LIB.OLB"]

#DboLib_ReplaceCache wrapper
proc ReplaceCacheByName {partName} {
    global oldLibName
    global newLibName
    global lDesign
    set lPartStr [DboTclHelper_sMakeCString $partName]
