database update not executed in Exception

[Yebach]

Hello

In my try-Except block I have a db update to update database back to initial value if code fail. Looks like update is not executed.

except Exception as e:
    "Če je napaka pri ustavljanju woshi engina"
    #db.rollback()
    db(db.scripts.id == scriptId).update(sc_status = 10)
    db.commit()
    print db._lastsql
    print "skripta %s v status 10!" %(str(scriptId))
    "pobrišemo tudi datoteke ker drugače bo engine še kr laufov"
    #Pobiršem out file če obstaja v mapi engine/e1 in sc_engine_out
    count = 0
    outPath= os.path.join(request.folder, 'engine', 'e1', str(scriptId) + '.out')
    while (count < 5 and ( os.path.isfile(outPath))):
        count += 1
        os.remove(outPath)
        time.sleep(0.05)

    count = 0
    llsFle = os.path.join(request.folder, 'engine', 'e1', str(scriptId) + '.lls')
    while (count < 5 and (os.path.isfile(llsFle))):
        count += 1
        os.remove(llsFle)
        time.sleep(0.05)


    exc_type, exc_obj, exc_tb = sys.exc_info()
    fname = os.path.split(exc_tb.tb_frame.f_code.co_filename)[1]
    errmsg = ["error pri parseOut funkciji", exc_type, fname, exc_tb.tb_lineno,e.__doc__ , e.message]
    print "errmsg ", errmsg
    print(exc_type, fname, exc_tb.tb_lineno)
    print e.__doc__
    print e.message
    #Writte error to log file
    exceptionLogger(errmsg, scriptId, org, auth.user_id)
    return {"error" : 666}

I tried with db.rollback() and it is the same. The print is shown, also the sql UPDATE scripts SET sc_status=10 WHERE (scripts.id = 434); is correct  and it works if executed on database.

any suggestions??

thank you
