I am new to BizTalk. I got a requirement as below.
Requirement is below:-
Source: Oracle (table). I created a generated schema in BizTalk.
Target: Webservice which receives "object array" (Table of source records from BizTalk) as an input.
Source and Target systems have same structure. Hence no mapping should be implemented. Logic should be in pipelines or orchestration.
Need info on below two topics:
How to incorporate the logic in pipeline or orchestration to map data from source schema to target WS schema.
This question was posed (now deleted) on the other big BizTalk forum. So I'll share my answer here.
What you're asking is simply not possible. It doesn't matter that the source and destination are logically the same. They are represented by two different schemas in BizTalk. There is no way around this except by developing the Web Service to accept the WCF Oracle message directly.
Because of that, you must transform from the source to the destination. Maps are how that is done. While there are technically other ways, they are harder to write, bug prone and would likely offer a less desirable performance profile.
A ban on Maps is just counter-productive and as a long time BizTalk Developer I could not accept a project with such a requirement.
It's not very clear what you are asking for to be honest. Your requirement states that no mapping is required, but then you go on to ask how to incorporate mapping in pipeline or orchestrations.
A standard approach to delivering this would be;
Setup your input process from Oracle by using "Consume Adapter
Service" from visual studio's "add generated item". Use the oracle
binding, setup connection properties for typed polling along with
your query (see here for an example on MS SQL) change to a
service contract type (for inbound operations) and you'll get a set
of schemas representing your dataset, and a binding for your type
receive port poller.
Use "Consume WCF Service" to point to your "sending" web service and
you'll get the schemas, binding and a helpful orchestration with
port types add to your project
Create a simple map mapping your inbound oracle recordset schema to
your web service schema - this should be pretty straight forward if
they are identical, although I suspect you'll have to deal with
multiple sets of data - depends on your data.
Complete by wiring together your orchestration.
I appreciate this is a high level view of what you need to do, but there are plenty of example you can google to get you started. Hope that helps.

Can I access persisted data of running orchestration Instances from the BizTalk database?
My BizTalk application deals with long-running processes and hundreds of orchestration instances can be running at a time.
I would like to access data persisted by these orchestration instances and display it on my application's UI. The data would give an insight about how many instances are running and at which state each of them is.
EDIT :
Let me try to be a little more specific.
My BizTalk application gets ticket requests (messages) from a source and after checking some business rules they are to be assigned to different departments of the company. The tickets can hop between inbox of different departments as each department completes its processing.
Now, the BizTalk orchestration instances are maintaining all the information that which department owns a particular ticket at a given time. I would want to read this orchestration information and generate inbox for each of the department at runtime. I can definitely do this by pushing this information to a separate database and populate the UI from there BUT as all this useful information is already available in the form of orchestration instances I would like to utilize it and avoid any syncing issues.
Does it make any sense?
The answer to your specific question is NO.
BAM exists for this purpose exactly.
Yes it is doable. Your question is little confusing. You can't get the data which is persisted for your orchestration instance, however You can get number of running or dehydrated instances using various options like WMI, ExplorerOM library. As a starting point you can look at some samples provided as part of BizTalk installation under SDK\Samples\Admin folder. Also you should be looking at MSBTS_ServiceInstance WMI class to get the service instances. You can also look at a sample http://msdn.microsoft.com/en-us/library/aa561219.aspx here. You can also use powershell to perform the same operation
I'm new to non-php web applications and to nosql databases. I was looking for a smart solution matching my application requirements and I was very surprised when I knew that there exist graph based db. Well I found neo4j very nice and very suitable for my application, but as I've already wrote I'm new to this and I have some limitations in understending how it works. I hope you guys could help me to learn.
If I embed neo4j in a servlet program then the database access I create is shared among the different threads of that servet right? so I need to put database creation in init() method and the shutdown in the destroy() right? And it will be thread safe.(every dot is a "right?") But what if I want to create a database shared among the whole application?
I heard that graph databases in general relies on a relational low level. Is that true for neo4j? But if it is then I see an high level interface to the real persistence layer, so what a Connection is in this case? Are there some techniques like connection pooling or these low level things are all managed by neo4j?
In my application I need to join some objects to users and many other classification stuff. any of these object has an unique id (a String). then If some one asks to view some stuff about object having id=QW then I need to load the vertex associate to object.QW. Is this an easy operation for graph datbases?
If I need to manage authentications, so as I receive the couple (usr,pwd) and I need to check whether exists this couple in my graph. Is the same problem as before or there exist some good variation for managing authentications?
thanks
If you're coming from PHP world in most cases you're better of running Neo4j in server mode and access it either via REST directly or use a client driver like https://github.com/jadell/neo4jphp. If you still want to embed Neo4j in a servlet environment, the GraphDatabaseService is a shared component, maybe stored within the ServletContext. On a per request (and therefore per-thread) basis you start and commit transactions.
Neo4j is a native graph database. The bare metal persistence layer is optimized for navigating from one node to its neighbors as fast as possible and written by the Neo4j devteam themselves. There are other graph databases out there reusing other persistence technologies for their underlying persistence.
Best thing is to run the Neo4j online course at http://www.neo4j.org/learn/online_course.
see SecurityRules
As the Neo4j is NoSql Graph Database,
Genration of the Unique ID you have to handle using the GUID(with 3.x autonincremented proery also supported for particular label),
as the Neo4j default genrated id is unique but can be realocated to the another object once the first assigned object is deleted,
I am .net developer in my project I used the Neo4j rest api it works well, i will sugesst you to go with that,as it is implemented using async-awit programing pattern, so long running operation you can pass to DB and utilize your web server resources in more prominent way.
I'm working on the following scenario:
I have a console up that populates a SQL Server database with some data. I have one more web app that reads the same database and displays the data on a front-end. Both of the applications use Entity Framework to communicate with the database (they have the same connection string).
I wonder how can the web app be notified for any changes that have occurred to the database. Bear in mind that the two applications are not referenced, whatsoever.
Is there event provided by EF that fires when some has changes. In essence, I would like to know when a change has happened, as well as, the nature of that change
I had a similar requirement and I solved it using the EF function:
[context].Database.CompatibleWithModel(throwIfNoMetadata: true)
It will return if your model matches the underlying database structure using the metadata table.
Note that I was using a Code First approach.
The msdn definition is below:
http://msdn.microsoft.com/en-us/library/system.data.entity.database.compatiblewithmodel(v=vs.103).aspx
Edit:
Just found an amazing article with a demonstration:
http://blog.oneunicorn.com/2011/04/08/code-first-what-is-that-edmmetadata-table/
This is not something that is related to EF at all. EF is just a library that makes SQL calls and maps them to objects. It has no inside knowledge of the database. As such, when data changes in one application, another application doesn't know unless they query to see if that data changes (and you're not going to be constantly running queries to know that, it's too impractical).
There are, potentially some ways to do this, such as adding triggers to the database, which then call extended stored procs to send messages to the app, but this is a lot of work to go through, and it can possibly compromise the robustness of the database.
There used to be something called Notification Services, but that was deprecated. There's now something called SqlDependency objects, which may help you in some cases.. but it all depends on what you're trying to do exactly.
In any event, it's usually easier to find a different way to do what you want. This is complex topic, and really requires a lot of sql server knowledge.
Need to make a tool to search XML data from BizTalk messagebox.
How do I search all XML data related to lets say a common node called Employee ID from all data stored in the BizTalk MessageBox?
The BizTalk Message Box (BizTalkMsgBoxDb database) is a transient store for messages as they pass through BizTalk. Once a message has finished processing, it will be removed from the Message Box.
You probably want to research Business Activity Monitoring (BAM) which will allow you to capture message data as messages flow through BizTalk; message data can be exposed through its generic web-based portal. BAM is a big product in its own right and I would suggest that you invest time in researching all of the available features to find the one that suits your particular scenario. There are many, many resources available, however you might start by taking look at Business Activity Monitoring. There is also a very good book specifically on BAM: Pro BAM in BizTalk Server 2009
Alternatively, take a look at using the built-in BizTalk Administration Console tools for querying the Tracking database (BizTalkDTADb) which will hold messages for later reference based on your pre-defined configuration options. See Using BizTalk Document Tracking.
Finally, you could consider rolling your own message tracking solution, writing message contents to a SQL Database table, as messages are received in a pipeline for example.
Check out the BizTalk Message Decompressor on CodePlex! I've been using this tool for a couple of years with excellent results. Since you're hitting the messagebox directly, you should be very careful and be very familiar with the queries that you choose to execute.
As noted by a previous poster's answer, BAM and the integrated HAT queries in the admin console are the official, safest, and Microsoft prescribed answers.
A lot of our use cases for Biztalk involve simply mapping and routing HL7 2.x messages from one system to another. Implementing maps and associating them to send/recieve ports is generally straightforward, but we also need to do some content based filtering on the sending side.
For example, we may want to only send ADT A04 and ADT A08 messages to system X if the sending facility is any 200 facilities (out of a possible 1000 facilities we have in our organization), but System Y needs ADT A04, A05, A8 for a totally different set of facilities and only for renal patients.
Because we're just routing messages and not really managing business processes here, utilzing orchestrations for the sole purpose to call out to the business rule engine is a little overkill here, especially considering that we'd probably need a seperate orchestration for each ADT type because of how schemas work. Is it possible to implement filter rules like this without using using orchestrations? The filters functionality of send ports looks a little too rudimentary for what we need, but at the same time I'd rather not develop and manage orchestrations.
You might be able to do this with property schemas...
You need to create a property schema and include the properties (from the other schemas) that you want to use for routing. Once you deploy the schema, those properties will be available for use as a filter in the send port. Start from here, you should be able to find examples somewhere...
As others have suggested you can use a custom pipeline component to call the Business Rules Engine.
And rather then trying to create your own, there is already an open source one available called the BizTalk Business Rules Engine Pipeline Framework
By calling BRE from the pipeline you can create complex rules which then set simple context properties on which you can route your messages.
Full disclosure: I've worked with the author of that framework when we were both at the same company.
