ADO事务处理方式运行正常

调用方式如下:
//找到初始化站点的配置数据

= null;
            IConfigurationElement[] rolesConfigElems 
= null;

= null;
            SetupConfigElems(
ref pluginsConfigElems,
                             
ref catalogsConfigElems,
                             
ref rolesConfigElems,
                             
ref usersConfigElems);

            
//第一步 创建站点数据
            DBTrans.ITransactionRoutine routineSaveSiteInDB = new RoutineSaveSiteInDB(m_siteMgr, m_site);

            
//第二步 创建默认的分配模块
            DBTrans.ITransactionRoutine routineAssignPlugins =
                
new RoutineAssignPlugins(m_site, pluginsConfigElems);

            
//第三步 创建固定的应用目录
            DBTrans.ITransactionRoutine routineCreateCatalogs =
                
new RoutineCreateCatalogs(m_site, catalogsConfigElems);

            
//第四步 创建固定的角色,创建固定的用户,并分配到角色中,并且给角色分配目录权限
            DBTrans.ITransactionRoutine routineCreateRoles =
                
new RoutineCreateRoles(m_site, rolesConfigElems, usersConfigElems);

            DBTrans.ITransactionRoutine[] routineList 
= {
                routineSaveSiteInDB,
                routineAssignPlugins,
                routineCreateCatalogs,
                routineCreateRoles
            }
;

            
try
            
{
                DBTrans.DoTransaction(
new string[] {dbConn},routineList);
            }

            
catch (ApplicationException ex)
            
{
                result.Success 
= false;
                result.KernelMessage 
= ex.InnerException.Message;
            }

            
return result;
