Databases :: Multiple Transactions In One Method?
Nov 10, 2010
I have an application which connect to oracle db.
I have two database hitting functions.
One is adding Userdetails(Fn Name : AddUserDtls) and another one adding address details(Fn name : AddAddresDtls) based on UserName which will get added after execution of first method ie AddUserDtls.
Problem I am facing is :
I have a single transaction and in that I have all the methods.
After the execution of first method,with out commiting i will go to second method.
and if any error occurs in second method.
I will rollback everything including the changes made by first method also.
Here one issue is there.
Since I am not committing the changes made by first method,
While I am executing the second method I am getting error that 'No user Name exists'
I understood that if we commit the transaction before the second method starts ,it will solve the issue.
But then it creates another problem.If some problem araise in the second method,then I cannot rollback the changes made by first method since it aleready commited.

Are there any transactions around multiple webservice calls.Let me start with a commonly used example -- the travel agency. A customer intends to create a travel plan through an online travel agency. To do this, the online travel application calls the following three Web services:
-Air ticket booking
-Hotel reservation
-Taxi reservation
These three services are available from three separate vendors. If any one of these three services fails, the customer does not wish to proceed with the transaction (again, either all three services must succeed or none at all).My language programming is Asp.net c#.

I am trying to delete three related objects on one submit. Delete fails on one of the child objects, because of foreign key contraint with another table, It deletes one (the parent) but not the two child objects. All in one SubmitChanges(). I even used the TransactionScope, still same thing. So here is the scenario:
I have an object called Page which has a collection of objects called Webinars. There is another object Called Product which is one to one with Webinar.

I am looking for an accepted pattern for using MVC 2 and EF. Especially I am interested on how to implement updates. Where should the ObjectContext be created, where should the queries be, how to pass a model object from the controller and have it persisted with minimum robust code. I also want to be able to use transactions when updating multiple objects.
I used Linq in an asp.net application (code behind model). With EF I was hearing it was much more n-tier friendly, but I don't find it any different, rather than people talking about POCO which to me, all it means is satisfying the desire of those that want to have control of every piece of code being created.

In my project's earlier version I used Stored Procedures (SPs) & directly used them inside presentation layer. SP contains multiple Insert & Update queries for multiple tables.
Now I have decided to use a DAL(Typed DataSets & TableAdapters)
How can i use the same SPs with TableAdapters or If not possible how to wrap Multiple TableAdapters inside Transactions.
1 more thing in my earlier version i was using Transaction in SPs & Presentation Layer.

I have used ASD.NET code using SQL Database for Transaction operation successfully. By changing the Database Code to interface with MYSQL an Error occurs. If I remove the Transaction Code from within the the application, it works OK by displaying the MYSQL data (Read Only) in the layout of the application. I am using Mysql Essential-4.1.22-win32 and MYSQL Connector ODBC-3.51.2. My objective is to EDIT the MYSQL Data.

Here is my beginning code which deals with one database:

In my web application, I have 2 totally different databases - one that's being used mostly by a CMS from which we'd like to get page information on non CMS pages on the same website, & one that contains totally different data. Is it possible to use Spring.NET's Open Session In View module with multiple session factories for both of those databases, so in this case I have 2 objects defined in spring.config of type Spring.Data.NHibernate.LocalSessionFactoryObject?

Is it better for a collection of ASP.NET web apps to share the same session database, or should each one have its own? If there is no significant difference, having a single database would be preferable due to easier maintenance. Background My team has an assortment of ASP.NET web apps, all written in either Monorail 1.1 or ASP.NET MVC 1.0. Each app currently uses a dedicated session state database. I'm working on adding a new site to that list, and am debating whether I should create another new session database, or just share an existing one with another app.

I am supposed to develop an enterprise-class ASP.NET Web Application that connects to multiple databases. For example when the web form loads, I should populate different ASP.NET controls (GridView, DataPager, TextBox, DropdownList etc) from multiple databases (SQL Server, Oracle, DB2, SAP Server etc) and also, edit the data in the controls and save the data to the respective databases on button submit.
Should I use Web Service or WCF for data integration, if so is there a limit on the size of the data?
What should be the architecture considering the application should be scalable and easy to maintain?

I have a quick question about best practices and especially expected performance for the following scenario:
If I want to query data from multiple servers that contain schematically identital sql databases, would having each server provide a web method that a single client application can consume be an appropriate (and relatively fast) solution?
The data just needs to be consolidated on the client end, where several web methods would have to be consumed serially (or in parallel?) to provide the data to the client. Each server would also be implementing Entity Framework as an ORM.
Performance is my main concern here, would it turn out excessively slow as we start to scale up to more and more servers?

I'm currently working on an C#/ASP.NET project that will host several differents e-commerce websites, all running in the same application.I use LinqToSql (moving to PLINQO soon) to access my database. The database contains both informations on the website structure (pages, ...) and the products/orders/users data.
My question is, should I use only one database for all the websites, or sould I create a new database (same model) for every new website?I'm now using a single database (with SiteIDs in some tables) but I have a big security concern, I can't just backup/restore the database for ONE website if something goes wrong (e.g. somebody erase all the products on ONE website) and it's an important requirment of the application.
So I was wondering what are the good practices in that case? Is there big cons if splitting dbs?(I would have to make changes to several database instead of one in case of structural changes, but i guess i can make a db version/update system).How the existing CRMs are dealing with that?Is it a performance problem if a database server host a lot of different DataBases? A complex backup/restore tool would be better?
Subquestion:To make a website replication easy, I can also split the pure CMS data (Pages, Texts, ...) in one DB and the e-commerce data (products/categories/orders in another). It can be achieved by some select/insert functions but it would be easier by just copying a database of course.

Consider that I want to create 10 websites in IIS, each of them pointing to the same website on local hard drive, each one running the same code, but on different subdomain.subdomain1.domain.com, subdomain2.domain.com, ..., subdomain10.domain.comHow can I add multiple connection strings in my web.config file and bind each connection string to a different subdomain ?I want to do this because every website will have a different database with different data.
