  • Debugging OWB generated SAP ABAP code executed through RFC

    - by Anil Menon
    Within OWB if you need to execute ABAP code using RFC you will have to use the SAP Function Module RFC_ABAP_INSTALL_AND_RUN. This function module is specified during the creation of the SAP source location. Usually in a Production environment a copy of this function module is used due to security restrictions. When you execute the mapping by using this Function Module you can’t see the actual ABAP code that is passed on to the SAP system. In case you want to take a look at the code that will be executed on the SAP system you need to use a custom Function Module in SAP. The easiest way to do this is to make a copy of the Function Module RFC_ABAP_INSTALL_AND_RUN and call it say Z_TEST_FM. Then edit the code of the Function Module in SAP as below FUNCTION Z_TEST_FM . DATA: BEGIN OF listobj OCCURS 20. INCLUDE STRUCTURE abaplist. DATA: END OF listobj. DATA: begin_of_line(72). DATA: line_end_char(1). DATA: line_length type I. DATA: lin(72). loop at program. append program-line to WRITES. endloop. ENDFUNCTION. Within OWB edit the SAP Location and use Z_TEST_FM as the “Execution Function Module” instead of  RFC_ABAP_INSTALL_AND_RUN. Then register this location. The Mapping you want to debug will have to be deployed. After deployment you can right click the mapping and click on “Start”.   After clicking start the “Input Parameters” screen will be displayed. You can make changes here if you need to. Check that the parameter BACKGROUND is set to “TRUE”. After Clicking “OK” the log for the execution will be displayed. The execution of Mappings will always fail when you use the above function module. Clicking on the icon “I” (information) the ABAP code will be displayed.   The ABAP code displayed is the code that is passed through the Function Module. You can also find the code by going through the log files on the server which hosts the OWB repository. The logs will be located under <OWB_HOME>/owb/log. Patch #12951045 is recommended while using the SAP Connector with OWB 11.2.0.2. For recommended patches for other releases please check with Oracle Support at http://support.oracle.com

  • URL Routing in ASP.NET 4.0

    In the .NET Framework 3.5 SP1, Microsoft introduced ASP.NET Routing, which decouples the URL of a resource from the physical file on the web server. With ASP.NET Routing you, the developer, define routing rules map route patterns to a class that generates the content. For example, you might indicate that the URL Categories/CategoryName maps to a class that takes the CategoryName and generates HTML that lists that category's products in a grid. With such a mapping, users could view products for the Beverages category by visiting www.yoursite.com/Categories/Beverages. In .NET 3.5 SP1, ASP.NET Routing was primarily designed for ASP.NET MVC applications, although as discussed in Using ASP.NET Routing Without ASP.NET MVC it is possible to implement ASP.NET Routing in a Web Forms application, as well. However, implementing ASP.NET Routing in a Web Forms application involves a bit of seemingly excessive legwork. In a Web Forms scenario we typically want to map a routing pattern to an actual ASP.NET page. To do so we need to create a route handler class that is invoked when the routing URL is requested and, in a sense, dispatches the request to the appropriate ASP.NET page. For instance, to map a route to a physical file, such as mapping Categories/CategoryName to ShowProductsByCategory.aspx - requires three steps: (1) Define the mapping in Global.asax, which maps a route pattern to a route handler class; (2) Create the route handler class, which is responsible for parsing the URL, storing any route parameters into some location that is accessible to the target page (such as HttpContext.Items), and returning an instance of the target page or HTTP Handler that handles the requested route; and (3) writing code in the target page to grab the route parameters and use them in rendering its content. Given how much effort it took to just read the preceding sentence (let alone write it) you can imagine that implementing ASP.NET Routing in a Web Forms application is not necessarily the most straightforward task. The good news is that ASP.NET 4.0 has greatly simplified ASP.NET Routing for Web Form applications by adding a number of classes and helper methods that can be used to encapsulate the aforementioned complexity. With ASP.NET 4.0 it's easier to define the routing rules and there's no need to create a custom route handling class. This article details these enhancements. Read on to learn more! Read More >

  • Can we replace XML with JSON entirely?

    - by Saeed Neamati
    I'm sure lots of developers are familiar with XML and JSON, and they've used both of them. Thus no point in explaining what they are, and what is their purpose, even in brief. If we try to map their concepts, we can say (correct me if I'm wrong): XML tags are equivalent to JSON {} XML attributes are equivalent to JSON properties XML tag collection is equivalent to JSON [] The only thing I can think of, which doesn't exist in JSON, is XML Namespaces. The question is, considering this mapping, and considering that JSON is highly lighter in this mapping, can we see a world in future (or at least theoretically think of a world) without XML, but with JSON doing everything XML does? Can we use JSON everywhere XML is used? PS: Please note that I've seen this question. It's something entirely different from what I'm asking here. Thus please don't mention duplicate.

  • Using CTAS & Exchange Partition Replace IAS for Copying Partition on Exadata

    - by Bandari Huang
    Usage Scenario: Copy data&index from one partition to another partition in a partitioned table. Solution: Create a partition definition Copy data from one partition to another partiton by 'Insert as select (IAS)' Create a nonpartitioned table by 'Create table as select (CTAS)' Convert a nonpartitioned table into a partition of partitoned table by exchangng their data segments. Rebuild unusable index Exchange Partition Convertion Mutual convertion between a partition (or subpartition) and a nonpartitioned table Mutual convertion between a hash-partitioned table and a partition of a composite *-hash partitioned table Mutual convertiton a [range | list]-partitioned table into a partition of a composite *-[range | list] partitioned table. Exchange Partition Usage Scenario High-speed data loading of new, incremental data into an existing partitioned table in DW environment Exchanging old data partitions out of a partitioned table, the data is purged from the partitioned table without actually being deleted and can be archived separately Exchange Partition Syntax ALTER TABLE schema.table EXCHANGE [PARTITION|SUBPARTITION] [partition|subprtition] WITH TABLE schema.table [INCLUDE|EXCLUDING] INDEX [WITH|WITHOUT] VALIDATION UPDATE [INDEXES|GLOBAL INDEXES] INCLUDING | EXCLUDING INDEXES Specify INCLUDING INDEXES if you want local index partitions or subpartitions to be exchanged with the corresponding table index (for a nonpartitioned table) or local indexes (for a hash-partitioned table). Specify EXCLUDING INDEXES if you want all index partitions or subpartitions corresponding to the partition and all the regular indexes and index partitions on the exchanged table to be marked UNUSABLE. If you omit this clause, then the default is EXCLUDING INDEXES. WITH | WITHOUT VALIDATION Specify WITH VALIDATION if you want Oracle Database to return an error if any rows in the exchanged table do not map into partitions or subpartitions being exchanged. Specify WITHOUT VALIDATION if you do not want Oracle Database to check the proper mapping of rows in the exchanged table. If you omit this clause, then the default is WITH VALIDATION.  UPADATE INDEX|GLOBAL INDEX Unless you specify UPDATE INDEXES, the database marks UNUSABLE the global indexes or all global index partitions on the table whose partition is being exchanged. Global indexes or global index partitions on the table being exchanged remain invalidated. (You cannot use UPDATE INDEXES for index-organized tables. Use UPDATE GLOBAL INDEXES instead.) Exchanging Partitions&Subpartitions Notes Both tables involved in the exchange must have the same primary key, and no validated foreign keys can be referencing either of the tables unless the referenced table is empty.  When exchanging partitioned index-organized tables: – The source and target table or partition must have their primary key set on the same columns, in the same order. – If key compression is enabled, then it must be enabled for both the source and the target, and with the same prefix length. – Both the source and target must be index organized. – Both the source and target must have overflow segments, or neither can have overflow segments. Also, both the source and target must have mapping tables, or neither can have a mapping table. – Both the source and target must have identical storage attributes for any LOB columns.

  • Using heavyweight ORM implementation for light based games

    - by Holland
    I'm just about to engulf myself in an MVC-based/Component architecture in C#, using MySQL's connector/Net for the data storage, and probably some NHibernate/FluentNHibernate Object-relational-mapping to map out the data structure. The goal is to build a scalable 2D RPG. Then I think about it...and I can't help but think this seems a little "heavy weight" for a 2D RPG, especially one which, while I plan to incorporate a lot of functionality and entertaining gameplay, may be ported to something like Windows Phone or Android in the future. Yet, on the other hand even a 2-Dimensional RPG can become very complicated, and therefore must incorporate a lot of functionality. While this can be accomplished with text/XML/JSON for data storage, is there a better way? Is something such as Object-Relational-Mapping useful in such an application? So, what do you think? Would you say that there is a place for such technologies? I don't know what to think...

  • Collision filtering techniques

    - by Griffin
    I was wondering what efficient techniques are out there for mapping collision filtering between various bodies, sub-bodies, and so forth. I'm familiar with the simple idea of having different layers of 2D bodies, but this is not sufficient for more complex mapping: (Think of having sub-bodies of a body, such as limbs, collide with each other by placing them on the same layer, and then wanting to only have the legs collide with the ground while the arms would not) This can be solved with a multidimensional layer setup, but I would probably end up just creating more and more layers to the point where the simplicity and efficiency of layer filtering would be gone. Are there any more complex ways to solve even more complex situations than this?

  • Why we do not use PowerConnect to access PeopleSoft Tree

    - by dylan.wan
    1. It does not allow you to use parameters to the PeopleSoft connect. It may be changed later. However, it was a big issue when we try to address customer issues. 2. It requires EFFDT as an option. It expect that people change the EFFDT using Mapping Editor. How can a business user does that every month? 3. It asks for a Tree Name. Many PeopleSoft tree structure supports multiple trees. Tree is just a header of the hierarchy. Whenever you add a new Tree, you need to create a new mapping!! It does not make sense to use PowerConnect due to the customer demands. All requirements are from customers. We have no choice but stop using it.

  • blurry lines between web application context layer, service layer and data access layer in spring

    - by thenaglecode
    I Originally asked this question in SO but on advice I have moved the question here... I'll admit I'm a spring newbie, but you can correct me if I'm wrong, this one liner looks kinda fishy in a best practices sort of way: @RepositoryRestResource(collectionResourceRel="people"...) public interface PersonRepository extends PagingAndSortingRepository<Person, Long> For those who are unaware, the following does many things: It is an interface definition that can be registered in an application context as a jpa repository, automagically hooking up all the default CRUD operations within a persistence context (that is externally configured). and also configures default controller/request-mapping/handler functionality at the namespace "/people" relative to your configured dispatcher servlet-mapping. Here's my point. I just crossed 3 conceptual layers with one line of code! this feels against my seperation-of-concern instincts but i wanted to hear your opinion. And for the sake of being on a question and answer site, I would like to know whether there is a better way of seperating these different layers - Service, Data, Controllers - whilst maintaining as minimal configuration as possible

  • Q&amp;A: Will my favourite ORM Foo work with SQL Azure?

    - by Eric Nelson
    short answer: Quite probably, as SQL Azure is very similar to SQL Server longer answer: Object Relational Mappers (ORMs) that work with SQL Server are likely but not guaranteed to work with SQL Azure. The differences between the RDBMS versions are small – but may cause problems, for example in tools used to create the mapping between objects and tables or in generated SQL from the ORM which expects “certain things” :-) More specifically: ADO.NET Entity Framework / LINQ to Entities can be used with SQL Azure, but the Visual Studio designer does not currently work. You will need to point the designer at a version of your database running of SQL Server to create the mapping, then change the connection details to run against SQL Azure. LINQ to SQL has similar issues to ADO.NET Entity Framework above NHibernate can be used against SQL Azure DevExpress XPO supports SQL Azure from version 9.3 DataObjects.Net supports SQL Azure Open Access from Telerik works “seamlessly”  - their words not mine :-) The list above is by no means comprehensive – please leave a comment with details of other ORMs that work (or do not work) with SQL Azure.

  • Windows 8 keyboard shortcuts when virtualising OS X

    - by mbrit
    Seriously, I have no idea why this took me so long to actually sort out.So in Windows 8 you have new keyboard shortcuts for accessing search (Win+Q), charms (Win+C), settings (Win+I), etc. Problem is that some of those collide with standard OS X mapping - for example Win+Q will close down VMware, Win+C will issue copy, etc.You can add additional mappings into VMware. Use the Preferences panel to do that. Here you can see that I've mapped Win+Shift+C to Win+C. (OK, that assumes you use a Windows keyboard with a Mac, like I do. If you use a Mac keyboard, you're mapping Apple+Shift+C to Win+C.)

  • Faster, Simpler access to Azure Tables with Enzo Azure API

    - by Herve Roggero
    After developing the latest version of Enzo Cloud Backup I took the time to create an API that would simplify access to Azure Tables (the Enzo Azure API). At first, my goal was to make the code simpler compared to the Microsoft Azure SDK. But as it turns out it is also a little faster; and when using the specialized methods (the fetch strategies) it is much faster out of the box than the Microsoft SDK, unless you start creating complex parallel and resilient routines yourself. Last but not least, I decided to add a few extension methods that I think you will find attractive, such as the ability to transform a list of entities into a DataTable. So let’s review each area in more details. Simpler Code My first objective was to make the API much easier to use than the Azure SDK. I wanted to reduce the amount of code necessary to fetch entities, remove the code needed to add automatic retries and handle transient conditions, and give additional control, such as a way to cancel operations, obtain basic statistics on the calls, and control the maximum number of REST calls the API generates in an attempt to avoid throttling conditions in the first place (something you cannot do with the Azure SDK at this time). Strongly Typed Before diving into the code, the following examples rely on a strongly typed class called MyData. The way MyData is defined for the Azure SDK is similar to the Enzo Azure API, with the exception that they inherit from different classes. With the Azure SDK, classes that represent entities must inherit from TableServiceEntity, while classes with the Enzo Azure API must inherit from BaseAzureTable or implement a specific interface. // With the SDK public class MyData1 : TableServiceEntity {     public string Message { get; set; }     public string Level { get; set; }     public string Severity { get; set; } } //  With the Enzo Azure API public class MyData2 : BaseAzureTable {     public string Message { get; set; }     public string Level { get; set; }     public string Severity { get; set; } } Simpler Code Now that the classes representing an Azure Table entity are defined, let’s review the methods that the Azure SDK would look like when fetching all the entities from an Azure Table (note the use of a few variables: the _tableName variable stores the name of the Azure Table, and the ConnectionString property returns the connection string for the Storage Account containing the table): // With the Azure SDK public List<MyData1> FetchAllEntities() {      CloudStorageAccount storageAccount = CloudStorageAccount.Parse(ConnectionString);      CloudTableClient tableClient = storageAccount.CreateCloudTableClient();      TableServiceContext serviceContext = tableClient.GetDataServiceContext();      CloudTableQuery<MyData1> partitionQuery =         (from e in serviceContext.CreateQuery<MyData1>(_tableName)         select new MyData1()         {            PartitionKey = e.PartitionKey,            RowKey = e.RowKey,            Timestamp = e.Timestamp,            Message = e.Message,            Level = e.Level,            Severity = e.Severity            }).AsTableServiceQuery<MyData1>();        return partitionQuery.ToList();  } This code gives you automatic retries because the AsTableServiceQuery does that for you. Also, note that this method is strongly-typed because it is using LINQ. Although this doesn’t look like too much code at first glance, you are actually mapping the strongly-typed object manually. So for larger entities, with dozens of properties, your code will grow. And from a maintenance standpoint, when a new property is added, you may need to change the mapping code. You will also note that the mapping being performed is optional; it is desired when you want to retrieve specific properties of the entities (not all) to reduce the network traffic. If you do not specify the properties you want, all the properties will be returned; in this example we are returning the Message, Level and Severity properties (in addition to the required PartitionKey, RowKey and Timestamp). The Enzo Azure API does the mapping automatically and also handles automatic reties when fetching entities. The equivalent code to fetch all the entities (with the same three properties) from the same Azure Table looks like this: // With the Enzo Azure API public List<MyData2> FetchAllEntities() {        AzureTable at = new AzureTable(_accountName, _accountKey, _ssl, _tableName);        List<MyData2> res = at.Fetch<MyData2>("", "Message,Level,Severity");        return res; } As you can see, the Enzo Azure API returns the entities already strongly typed, so there is no need to map the output. Also, the Enzo Azure API makes it easy to specify the list of properties to return, and to specify a filter as well (no filter was provided in this example; the filter is passed as the first parameter).  Fetch Strategies Both approaches discussed above fetch the data sequentially. In addition to the linear/sequential fetch methods, the Enzo Azure API provides specific fetch strategies. Fetch strategies are designed to prepare a set of REST calls, executed in parallel, in a way that performs faster that if you were to fetch the data sequentially. For example, if the PartitionKey is a GUID string, you could prepare multiple calls, providing appropriate filters ([‘a’, ‘b’[, [‘b’, ‘c’[, [‘c’, ‘d[, …), and send those calls in parallel. As you can imagine, the code necessary to create these requests would be fairly large. With the Enzo Azure API, two strategies are provided out of the box: the GUID and List strategies. If you are interested in how these strategies work, see the Enzo Azure API Online Help. Here is an example code that performs parallel requests using the GUID strategy (which executes more than 2 t o3 times faster than the sequential methods discussed previously): public List<MyData2> FetchAllEntitiesGUID() {     AzureTable at = new AzureTable(_accountName, _accountKey, _ssl, _tableName);     List<MyData2> res = at.FetchWithGuid<MyData2>("", "Message,Level,Severity");     return res; } Faster Results With Sequential Fetch Methods Developing a faster API wasn’t a primary objective; but it appears that the performance tests performed with the Enzo Azure API deliver the data a little faster out of the box (5%-10% on average, and sometimes to up 50% faster) with the sequential fetch methods. Although the amount of data is the same regardless of the approach (and the REST calls are almost exactly identical), the object mapping approach is different. So it is likely that the slight performance increase is due to a lighter API. Using LINQ offers many advantages and tremendous flexibility; nevertheless when fetching data it seems that the Enzo Azure API delivers faster.  For example, the same code previously discussed delivered the following results when fetching 3,000 entities (about 1KB each). The average elapsed time shows that the Azure SDK returned the 3000 entities in about 5.9 seconds on average, while the Enzo Azure API took 4.2 seconds on average (39% improvement). With Fetch Strategies When using the fetch strategies we are no longer comparing apples to apples; the Azure SDK is not designed to implement fetch strategies out of the box, so you would need to code the strategies yourself. Nevertheless I wanted to provide out of the box capabilities, and as a result you see a test that returned about 10,000 entities (1KB each entity), and an average execution time over 5 runs. The Azure SDK implemented a sequential fetch while the Enzo Azure API implemented the List fetch strategy. The fetch strategy was 2.3 times faster. Note that the following test hit a limit on my network bandwidth quickly (3.56Mbps), so the results of the fetch strategy is significantly below what it could be with a higher bandwidth. Additional Methods The API wouldn’t be complete without support for a few important methods other than the fetch methods discussed previously. The Enzo Azure API offers these additional capabilities: - Support for batch updates, deletes and inserts - Conversion of entities to DataRow, and List<> to a DataTable - Extension methods for Delete, Merge, Update, Insert - Support for asynchronous calls and cancellation - Support for fetch statistics (total bytes, total REST calls, retries…) For more information, visit http://www.bluesyntax.net or go directly to the Enzo Azure API page (http://www.bluesyntax.net/EnzoAzureAPI.aspx).

  • How to get Rosegarden to work with timidity?

    - by molybtek
    I'm having problems getting Rosegarden to play midi using Timidity on Ubuntu 11.10 amd64. I've tried mapping the MIDI playback device to one of the Timidity port that was automatically created on start up and that failed. I've also tried manually starting timidity using the -iA option, and mapping the Rosegarden's MIDI playback device to one of the new ports, and that still failed. When I close Rosegarden, I can hear one or two notes get played. Would anyone know how I can get Rosegarden to work again. Thanks.

  • Samba: map domain group to local one

    - by user285467
    I have a problem with mapping pure domain group to one existing on UNIX system. When I map NT domain account by default samba picks local SID - one that can be acquired via the command; net getlocalsid Instead of SID that comes from domain; net getdomainsid This is the behavior that I do not understand. I can explicitly set the SID to the domain one. E.g.: net groupmap add sid=[DOMAIN SID]-[RID] ntgroup=[DOMAIN group] unixgroup=[UNIX group] type=l However the command getent group | grep 'DOMAIN group indicates this group to be domain one - GID created in accordance to RID backend in use, not the GID of 'UNIX group' as expected. Worth to mention I use the winbind. Strange thing is that I already have such mapping in place for other 'DOMAIN group2' that getent group reports with GID of local UNIX group with all members of the 'DOMAIN group2'. Now the question is how to populate such behavior for other of my groups???

  • nhibernate configure and buildsessionfactory time

    - by davidsleeps
    Hi, I'm using Nhibernate as the OR/M tool for an asp.net application and the startup performance is really frustrating. Part of the problem is definitely me in my lack of understanding but I've tried a fair bit (understanding is definitely improving) and am still getting nowhere. Currently ANTS profiler has that the Configure() takes 13-18 seconds and the BuildSessionFActory() as taking about 5 seconds. From what i've read, these times might actually be pretty good, but they were generally talking about hundreds upon hundreds of mapped entities...this project only has 10. I've combined all the mapping files into a single hbm mapping file and this did improve things but only down to the times mentioned above... I guess, are there any "Traps for young players" that are regularly missed...obvious "I did this/have you enabled that/exclude file x/mark file y as z" etc... I'll try the serialize the configuration thing to avoid the Configure() stage, but I feel that part shouldn't be that long for that amount of entities and so would essentially be hiding a current problem... I will post source code or configuration if necessary, but I'm not sure what to put in really... thanks heaps! edit (more info) I'll also add that once this is completed, each page is extremely quick... configuration code- hibernate.cfg.xml <?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <section name="hibernate-configuration" type="NHibernate.Cfg.ConfigurationSectionHandler, NHibernate" /> </configSections> <hibernate-configuration xmlns="urn:nhibernate-configuration-2.2"> <session-factory> <property name="dialect">NHibernate.Dialect.MsSql2005Dialect</property> <property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property> <property name="connection.driver_class">NHibernate.Driver.SqlClientDriver</property> <property name="connection.connection_string_name">MyAppDEV</property> <property name="cache.provider_class">NHibernate.Caches.SysCache.SysCacheProvider, NHibernate.Caches.SysCache</property> <property name="cache.use_second_level_cache">true</property> <property name="show_sql">false</property> <property name="proxyfactory.factory_class">NHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle</property> <property name="current_session_context_class">managed_web</property> <mapping assembly="MyApp.Domain"/> </session-factory> </hibernate-configuration> </configuration> My SessionManager class which is bound and unbound in a HttpModule for each request Imports NHibernate Imports NHibernate.Cfg Public Class SessionManager Private ReadOnly _sessionFactory As ISessionFactory Public Shared ReadOnly Property SessionFactory() As ISessionFactory Get Return Instance._sessionFactory End Get End Property Private Function GetSessionFactory() As ISessionFactory Return _sessionFactory End Function Public Shared ReadOnly Property Instance() As SessionManager Get Return NestedSessionManager.theSessionManager End Get End Property Public Shared Function OpenSession() As ISession Return Instance.GetSessionFactory().OpenSession() End Function Public Shared ReadOnly Property CurrentSession() As ISession Get Return Instance.GetSessionFactory().GetCurrentSession() End Get End Property Private Sub New() Dim configuration As Configuration = New Configuration().Configure() _sessionFactory = configuration.BuildSessionFactory() End Sub Private Class NestedSessionManager Friend Shared ReadOnly theSessionManager As New SessionManager() End Class End Class edit 2 (log4net results) will post bits that have a portion of time between them and will cut out the rest... 2010-03-30 23:29:40,898 [4] INFO NHibernate.Cfg.Environment [(null)] - Using reflection optimizer 2010-03-30 23:29:42,481 [4] DEBUG NHibernate.Cfg.Configuration [(null)] - dialect=NHibernate.Dialect.MsSql2005Dialect ... 2010-03-30 23:29:42,501 [4] INFO NHibernate.Cfg.Configuration [(null)] - Mapping resource: MyApp.Domain.Mappings.hbm.xml 2010-03-30 23:29:43,342 [4] INFO NHibernate.Dialect.Dialect [(null)] - Using dialect: NHibernate.Dialect.MsSql2005Dialect 2010-03-30 23:29:50,462 [4] INFO NHibernate.Cfg.XmlHbmBinding.Binder [(null)] - Mapping class: ... 2010-03-30 23:29:51,353 [4] DEBUG NHibernate.Connection.DriverConnectionProvider [(null)] - Obtaining IDbConnection from Driver 2010-03-30 23:29:53,136 [4] DEBUG NHibernate.Connection.ConnectionProvider [(null)] - Closing connection

  • NHibernate won't persist DateTime SqlDateTime overflow

    - by chris raethke
    I am working on an ASP.NET MVC project with NHibernate as the backend and am having some trouble getting some dates to write back to my SQL Server database tables. These date fields are NOT nullable, so the many answers here about how to setup nullable datetimes have not helped. Basically when I try to save the entity which has a DateAdded and a LastUpdated fields, I am getting a SqlDateTime overflow exception. I have had a similar problem in the past where I was trying to write a datetime field into a smalldatetime column, updating the type on the column appeared to fix the problem. My gut feeling is that its going to be some problem with the table definition or some type of incompatible data types, and the overflow exception is a bit of a bum steer. I have attached an example of the table definition and the query that NHibernate is trying to run, any help or suggestions would be greatly appreciated. CREATE TABLE [dbo].[CustomPages]( [ID] [uniqueidentifier] NOT NULL, [StoreID] [uniqueidentifier] NOT NULL, [DateAdded] [datetime] NOT NULL, [AddedByID] [uniqueidentifier] NOT NULL, [LastUpdated] [datetime] NOT NULL, [LastUpdatedByID] [uniqueidentifier] NOT NULL, [Title] [nvarchar](150) NOT NULL, [Term] [nvarchar](150) NOT NULL, [Content] [ntext] NULL ) exec sp_executesql N'INSERT INTO CustomPages (Title, Term, Content, LastUpdated, DateAdded, StoreID, LastUpdatedById, AddedById, ID) VALUES (@p0, @p1, @p2, @p3, @p4, @p5, @p6, @p7, @p8)',N'@p0 nvarchar(21),@p1 nvarchar(21),@p2 nvarchar(33),@p3 datetime,@p4 datetime,@p5 uniqueidentifier,@p6 uniqueidentifier,@p7 uniqueidentifier,@p8 uniqueidentifier',@p0=N'Size and Colour Chart',@p1=N'size-and-colour-chart',@p2=N'This is the size and colour chart',@p3=''2009-03-14 14:29:37:000'',@p4=''2009-03-14 14:29:37:000'',@p5='48315F9F-0E00-4654-A2C0-62FB466E529D',@p6='1480221A-605A-4D72-B0E5-E1FE72C5D43C',@p7='1480221A-605A-4D72-B0E5-E1FE72C5D43C',@p8='1E421F9E-9A00-49CF-9180-DCD22FCE7F55' In response the the answers/comments, I am using Fluent NHibernate and the generated mapping is below public CustomPageMap() { WithTable("CustomPages"); Id( x => x.ID, "ID" ) .WithUnsavedValue(Guid.Empty) .

  • Hibernate + PostgreSQL : relation does not exist - SQL Error: 0, SQLState: 42P01

    Hello, I am having some problems trying to work with PostgreSQL and Hibernate, more specifically, the issue mentioned in the title. I've been searching the net for a few hours now but none of the found solutions worked for me. I am using Eclipse Java EE IDE for Web Developers.

Everything is lowercase, so I don't think that it's that issue. If I switch to MySQL, the same code same project (I only change driver,URL, authentication), it works. In Eclipse Datasource Explorer, I can ping the DB and it succeeds. Weird thing is that I can't see the tables from there either. It expands the public schema but it doesn't expand the tables. Could it be some permission issue? Thanks!

  • WS2008 subst in Logon script does not "stick"

    - by Frans
    I have a terminal server environment exclusively with Windows Server 2008. My problem is that I need to "map" a drive letter to each users Temp folder. This is due to a legacy app that requries a separate Temp folder for each user but which does not understand %temp%. So, just add "subst t: %temp%" to the logon script, right? The problem is that, even though the command runs, the subst doesn't "stick" and the user doesn't get a T: drive. Here is what I have tried; The simplest version: 'Mapping a temp drive Set WinShell = WScript.CreateObject("WScript.Shell") WinShell.Run "subst T: %temp%", 2, True That didn't work, so tried this for more debug information: 'Mapping a temp drive Set WinShell = WScript.CreateObject("WScript.Shell") Set procEnv = WinShell.Environment("Process") wscript.echo(procEnv("TEMP")) tempDir = procEnv("TEMP") WinShell.Run "subst T: " & tempDir, 3, True This shows me the correct temp path when the user logs in - but still no T: Drive. Decided to resort to brute force and put this in my login script: 'Mapping a temp drive Set WinShell = WScript.CreateObject("WScript.Shell") WinShell.Run "\\domain\sysvol\esl.hosted\scripts\tempdir.cmd", 3, True where \domain\sysvol\esl.hosted\scripts\tempdir.cmd has this content: echo on subst t: %temp% pause When I log in with the above then the command window opens up and I can see the subst command being executed correctly, with the correct path. But still no T: drive. I have tried running all of the above scripts outside of a login script and they always work perfectly - this problem only occurs when doing it from inside a login script. I found a passing reference on an MSFN forum about a similar problem when the user is already logged on to another machine - but I have this problem even without being logged on to another machine. Any suggestion on how to overcome this will be much appreciated.
