Hi
This is the classificatio os Session Bean.
(1) Statfull
(2) Stateless
Stateful means u will persists the state of the object.

In a Banking system u can use the statful session just for maintaing the

(2) STATELESS: that's mean u do't want to persists any state of the object. that's mean a single Request is coming ,do the desire and give the output.

What's the difference between Routing and Service Callout in ALSB?

I am puzzled by that.
what's the difference between them.
Or what's the situation should use Routing, and that of service callout?

There is little difference between routing and service callout.
Routing is symbolizes the transition of request thread to a response thread starts. (in OSB every invocation of proxy is undertaken by different request and response threads ). So by this definition, there can be only one route node in a pipeline.
Service call out is also used for similar actions as route node , but in pipeline. So service callout can be either in request pipeline (request thread) or in response pipeline (response thread ) . So in a proxy you can have multiple ServiceCallouts but only one route node.
There are some other slight differences.

Difference between party and service

Hi,
I know when we are going to party and service (Normally party means. when we are doing Business to Business ) but what is exact difference between party and service.. and if possible definitions also..
Thanks
Babu.

Babu,
Refer to url http://help.sap.com/saphelp_nw04/helpdata/en/87/1d6e3fefa13042e10000000a114084/frameset.htm
An excerpt
Services without a party are typically used when configuring company-internal processes. Parties (with assigned services) are typically used when configuring cross-company processes.
Also refer to one of your previous forum questions and my response Re: Business System and Business Service Posted: Nov 28, 2007 4:31 PM in response to: BABU
You usually use business system services when configuring internal company processes.
You usually use business services when configuring cross-company processes. In this case, you only make your interfaces known to the business partners involved and either do not make any details about your own system landscape available, or only specific details.
Hope this helps,
Mike

Difference between a WEB service and a Enterprise Service?

Can Anybody explain me the difference between a WEB service and a Enterprise Service?

Hi Anilkumar K Naidu ,
Web service
A Web service is a self-contained, modularized functionality, which can be published, discovered, and accessed across a network using open standards and which is supported by SAP NetWeaver. Web services cover services provision for integration within an enterprise as well as cross enterprises on top of any communication technology stack, whether asynchronous or synchronous, in any format.
Web Services in the NetWeaver framework play an important role in facilitating the integration of disparate applications from various departments or trading partners and thus increasing business productivity. This benefit allows small and medium businesses also to integrate their business applications with larger trading partners. The benefit derived from this seamless integration introduces security concerns when all the business logic is now being exposed through a standard interface that is a catalyst for security vulnerabilities. SAP Security Managers must use automated diagnostics tools to ensure that the security vulnerabilities are caught in pre-production and in post-production phase.

Enterprise Service
Enterprise Service-Oriented Architecture (Enterprise SOA)
Enterprise SOA is a blueprint for an adaptable, flexible, and open IT architecture for developing services-based, enterprise-scale business solutions. With SAP NetWeaver as a technical foundation, enterprise SOA moves IT architectures to higher levels of adaptability and moves companies closer to the vision of real-time enterprises by elevating Web services to an enterprise level.
An enterprise service is typically a series of Web services combined with business logic that can be accessed and used repeatedly to support a particular business process. Aggregating Web services into business-level enterprise services provides a more meaningful foundation for the task of automating enterprise-scale business scenarios.

Difference between party and service without party

Hi all,
Please tell me the difference between Service and Service without party and also let me know what is Business system, Business service and Integration process.
regards,
sudha

Hi Sudha
Party
Party is used to represent a Business Partner (doesnt belong to the current landscape) which is defined in B2B Scenarios.So All the systems/services accociated with the Party are referred only as Services.
Service without Party
It is used to represent any service within the landscape and is used in A2A communication.
Check the Threads for reference...

Basic difference between stateful and entity beans???

Could anyone please explain the basic diff between stateful bean and an entity bean.as per my understanding,stateful beans are extensions to clients.they perform a job of a client and they r not persistent.also their state goes off when the server crashes or the machine is reeboted.while in contrast,an entity bean can retain its session coz' they represent a persistent field in the DB.What i have seen in few books(O'reilly,etc)where a session bean can insert some values into the DB,which means it also represents a persistent object in the DB,which contradicts the statement that "stateful session beans dont represent any persistent object in the DB".Could anyone please elaborate on this.Thanks in advance.
Jameel

Thank u very much crackers for ur valuable
suggestions.I'll throw a different one in here for free: clarity of writing is a highly-valued and useful skill in a software professional. This is especially true these days when concepts need to be clearly explained to a variety of technical peoples from all over the world. And then there's the other side of the coin: Management.
You have to get your thoughts across in a very precise manner and, unfortunately for those who have to learn it as a second lanugage, English seems to be the overall preferred medium. Which makes it even more important to use "correct" English in written communications. If you don't, your credibility diminishes and you appear to be (horrors!) unprofessional It's not that much harder to type "you" than it is to use a single letter. Besides, most people that "pay by the byte" appreciate the clarity, as well (as I've seen on Usenet, by way of covering my ass).
Now, back to our regularly scheduled post...
Is this wat u were trying to say if i
understood u correctly.Yes, the EntityBean is directly related to the data being persisted: in this case, a database table. So, using your example from below, the DB table would have two fields: a VARCHAR 'Name' and an INT 'Age.' The EntityBean would have corresponding fields/properties/variables, String name and int age.
"WHICH BEAN (Entity
or Sateful Session) SHOULD I GO 4???"No easy answer. The best one is: it depends. On what? It depends upon what you're trying to do with the data, how it's presented/manipulated, load requirements, environmental requirements, caching strategies, and about another dozen or so other high-level requirements.
My personal preference is if I need caching and the number of EntityBeans actually in existence is pretty "low" (another nebulous and arbitrary value, depending), I'll use a StatelessSessionBean as a Facade (search for "patterns" here in the forum), with the persistence in CMP EntityBeans. Which is influenced by the fact that I like playing with CMP. ;D

Difference between web server and presentation service

What are the differences between the Caching and the Software Update Services

New to working with OS X Server and am confused about the differences between the Caching Service and the Software Update Service...it seems to me that they overlap in that i) the Caching Service updates OS X software, iOS software and any apps purchased from the app store while ii) the Software Update service updates OS X software.
If the above is correct they why would one run both Services? I would think that one would run the Caching Service and call it a day!
And while on the subject, what about caching and pushing third party apps like MS Office?

Linc Davis wrote:
The simple answer is that you almost certainly don't need the Software Update service. Just use the Caching service. Neither one works with content that doesn't come from Apple.
Appreciate the response but could you please explain the difference between the two as that is the one item that remains unanswered.
Thanks,
Joel

Difference between service and communication user

Hi,
We ran into a big problem in our CRM system getting millions of Dynpro_Send_in_background dumps while processing inbound queues R3AD* from R/3 system to CRM. Lots of Updates getting failed with CRM_SCHEDLIN_UPDATE_DU function module while executing report LCRM_SCHEDLIN_DUU01.
Error Details - CRM_ORDER_MISC 002: Error in updating object SCHEDLIN
We posted to SAP as well but did not find root cause. SAP saying we need to change RFC user "S_ECC_PR0400" from Service user to Communication user, that would stop the dump problem.
I want to know what is the unique difference between these users(Service & Comm) which will resolve the dump problem though I know the common difference between these users.
Thanks
Anju

Hi Anju ,
Communication 'C' User :
Use the user type Communikation for dialog-free communication between systems (for RFC or CPIC service users of different applications, for example, ALE, Workflow, TMS ZBV).
Dialog logon is not possible.
Service 'S' User :
A user of type Service is a dialog user available to a large anonymous set of users. It usually has closely-restricted authorizations.
Service users are e.g. used for anonymous system access via an ITS service. You can change a session which began as an anonymous session with a service user into a personal session under a dialog user with an individual authentification.
There is no check for obsolete/initial passwords at logon. Only the user administrator can change the password.
Multiple logon is allowed.
Hope this may help you.
Thanks
Gyan

Difference Between Service Account and User Account

What is the Difference Between Service Account and User Account

Hello Mohit,
Basically there are two types of approches which you should understand.
In many environments, administrators prefer to simply create a domain user account and assign appropriate privileges to it. Then this user account is used in order to start a specific service on a computer.
In that case there is really no difference between a user account and the so called service accounts. Since this service account is simply a domain user, all the task related to managing the domain users apply to it. For example you
should keep the password up to date manually. Some environment move step forward and assign
Deny Logon Locally of this type of service account in order to enhance the security.
The second concept is Managed Service Accounts. There are plenty of differences between a Managed Service Account and a User Account.
The Display Icon is different from a view perspective.
The type of object is different.
Managed service accounts password management is automatic.
You can not create Managed Service Accounts using GUI. They are only created using Powershell.
You can refer to link below for more inormation:

Difference between user directory and native directory in Shared Services

Hi,
Please any one can help me......
I am new to Hyperion, what is difference between Hyperion Shared services Native directory and User/Active directory.
thanks in advance..............

Hi,
Shared Services native directory, as the name suggests, is a user directory (i.e. ldap) that is native to Hyperion. It allows you to create users, groups and define access rights to Hyperion Products. User/Active directory is the directory where users in your company reside. Shared Services can connect to it and retrieve the list of users and groups. You can define the access rights for these users if you configure the system in a way that it works with Active Directory.
You can use both combined also. Meaning, you can create user groups in native directory and assign native directory users into them and define access rights onto user groups and/or users.
Cheers,
Alp

Difference between automatic and non-automatic page attributes

Hi,
Can anyone tell me difference between automatic page attributes and non-automatic page attributes?
and also difference between stateful and stateless mode with examples?
Thanks
Narendra

Hi Mullapudi,
If you mark a page attribute as u2018automaticu2019 (auto in the system), the attribute automatically gets its values via the calling URL or
via the navigation process from other pages.
This kind of attribute only has to be declared for one page.
It is identified by its name equivalence.
If another page uses a parameter with the same name,
at runtime that parameter automatically
gets the same values as the attribute.
Non-automatic page attributes
If you flag a page attribute as non-automatic, the attribute gets its values from the class attribute.
The visibility of page attributes when parameters are transferred between BSP pages depends on whether the navigation is explicit or implicit.
Explicit navigation
For example, if navigation->goto_page(page.htm)
Implicit navigation
With implicit navigation, the page attributes are transferred automatically from OnInputProcessing to OnInitialization, both in stateful and stateless mode.
The auto page attributes are refilled by the request, both in stateful and stateless mode.
Reward if Useful...
Regards,
Anita. B
