Difference between XI adapter and HTTP adapter

Hi,
I am not very clear on the exact difference between XI adapter and HTTP adapter.
I want to know, when should we use XI adapter and when to use HTTP adapter.
Regards,
Santosh

Hi,
We use HTTP Adapter in case of the Application is trying to post the HTTP Request message to XI and able to receive the HTTP Message from XI also.
While using the HTTP as Sender , HTTP Sits on ABAP Stack and can able to communicate with the Integration Server Directly, No need of any Adapter here, it is adapterless communication
In Case of Client Proxies
Source application can directly interact with the XI by executing the report in SAP R/3 & will be able to send the XML data to IS,
So no need of the XI Adapter in this case to post xml to XI.
In Case of Server Proxies
Now XI has to post the xml data to the Target Application, here some thing shld be there to establish the medium with the Target System. So we use XI adapter here.
In the receiver case, we need XI Adaper to communicate XI integration Server with the Local Integration Engine( Which we made in SAP R/3's Business system as local IE) to post the data
Basically XI adapter will be used in normal scenarios also to communicate Adapter Engine with Integration Server internally while delivering the msg.
Check this Msg Flow how the XI Adapter is used in Normal Scenarios

Difference between Personalized url and Vanity url

Hi All,
Can any one plz let me know the difference between Personalized url and Vanity url interms of Weblogic Portal ?
thanks,
XXXXX

I'm not familiar with these concepts of personalized URLs and vanity URLs, but after a little bit of research it appears to pose the same issues as Search Engine Optimization as it relates to informative URLs.
Search on this forum for Search Engine Optimization or SEO and you'll find some ideas that should be equally applicable to personalized/vanity URLs.

Difference between urn and url

what's the difference between urn and url?

What is an URL
An Uniform Resource Locator (URL) is the term used to identify an Internet resource, and can be specified in a single line of text.
What is an URN
An Uniform Resource Name (URN) is the term used to identify an Internet resource, without the use of a scheme, and can be specified in a single line of text.
What is an URI
An Uniform Resource Identifier (URI) is used by a browser to identify a single document, and it too can be specified in a single line of text
The general form of an URL has four parts
A scheme followed by a colon.
Invokes a TCP/IP-based application level protocol
Schemes are: http, https, ftp, news, mailto, file, telnet.
A server name.
A // followed by the host name or IP address of the server
Not needed if the server is the default
news server
mail server
An optional port number. Standard or default port numbers are:
ftp *
ssh 22
telnet 23
smtp 25
gopher 70
http 80
nntp 119
SSL 443
A path.
Consisting of folders and/or files.
May include a file extension which identifies the type of document.
May also include a QUERY_STRING with arguments.
Ftp uses port 20 for data and port 21 for flow control.
DIFFERENCE BETWEEN URN & URI
The idea is that a URL is a mechanical link to a resource's location, where it can be downloaded. For this reason, a URL contains a hostname and a local part, all of which can be resolved anywhere on the Internet.
What a URN tries to do is different. It tries to give a description of a resource without actually pointing at it. For example:
urn:isbn:90-365-17273
URI: is a string that identifies any resource. Indentifying the resource does not necessarily mean we can retrieve it. URI is a superset of URL and URN.
files/reports/marketing/report.html
URL: URI that specify a common Internet protocol such as HTTP or FTP are also called URLs. URL is an informal term an is not used in technical specifications.
http://www.foo.com/files/reports/marketing/report.html
URN: A URN is an identifier the uniquely indentifies a resource but does not specify how to access that resource.

Difference between connection pooling and simple connection

Anybody please tell me what is the Difference between connection pooling and simple connection and also where we define connection pooling and how.
Thanks
Please reply soon
amitindia

Creating and closing connection to the database is a relatively slow process. Equally connections use database resources so you can't just open as many as you want.
A connection pool maintains a number of open connections throughout the lifetime of the application. Instead of opening and closing the connections your application just "borrows" them from the pool when they're needed.
If the pool runs out of connections it will usually create new ones as needed until you reach some predefined upper limit.
A good connection pool will also manage connections which have failed for any reason, and report code which fails to return connections to the pool (ie connection leaks).
The number of connections created at startup is referred to as the "low water mark" and the maximum number that the pool will allow to be opened at any given time is the "high water mark". If no connections are available client code will generally block until one is released.
If by "defined" you mean where can you get a working implementation then your database or application server vendor is likely to provide one. Also the Apache Jakarta Commons includes [url http://jakarta.apache.org/commons/dbcp/]an implementation which you can use with any JDBC driver.

Namespaces: Difference between URN & URI

hi,
Namespaces can either be defined according to URN or URI standards. Wanted to know if there is any fundamental difference between the two and when would one be prefered over the other, i.e. in what circumstance would you use URN and when would you opt for URI.
Manpreet

Hi Manpreet,
you use URI i.e. http://<name> when you wish to export your namespaces over the web.
This link will help you understand the concept in a much better manner:

Difference between webservices model and adaptive webservices model

hi
Can any one explain me regarding Difference between webservices model and adaptive webservices model.
Thanks

Hi,
In old WS Model, ithere was no concept of logical destinations.
There if you are using a WSDL located on a server and if the location of the WSDL
changes, your application won't run. The deployed application using the WS Model will have trouble finding
the WSDL. As a result you'll have to again import the
model. Moreover old WS Model does not have re-import functionality.
But incase of AWS Model, you can desine logical destinations and even if the location of the WSDL changes, all you have to do is change the new url in the Visual Admin and not import the model again.
You can visit the following link for more details:

Difference between RFC adapter and a proxy

Can any one tell me the technical difference between RFC adapter and a proxy?
reg

There are advantages / disadvantages for RFC / Proxies / Idocs. So if I am in your position depending upon the requirement I will choose one. Some of the differences are:
RFC and Proxy:
RFC/BAPI has its own overhead of function call.
Proxies communicate with the XI server by means of native SOAP calls over HTTP .RFC does not, so you have to convert from SOAP to RFC calls and vice versa. So XML conversion is required.
ABAP Proxies uses Webservice and Http Protocols.
If you use ABAP Proxy , you can reduce the overhead calling the function again and again.
Proxy and Idoc:
IDOC : After recieving the strucutred data It processes it using a Function Module associated with it.
Proxy : Proxy is a structure where there is no processing function module associated. You need to explicitly write the Business Logic/Call the subroutines here
This is my absolutely my view. Another guy has his own response. So first go through your requirements and then you can decide for what to go.
Also go through this urls which may help you:

Hi,
Upgrade SAP or Installation of SAP R/3 and ECC
What is ECC? Where to find the installation steps of ECC 5/6.0 with SQL as database and on windows platform with the steps including Solution Manager installation?
http://service.sap.com/instguides
ECC means Enterprise Central Component.
There are all the relevant installation guides. You NEED SAPNet access because without a registered and licensed SolMan installation number you will not be able to generate the SolMan key for the ECC installation.
Upgrade to 4.7
Have you gone through an upgrade to 4.7?
What are the difference or changes associated with 4.7.
If you are currently on 4.6C and are inching forward to upgrading to 4.7 then this information might be useful to you.
There is very little difference between 4.6 and 4.7, the only "steps" you should need are steps in SU25 ( skip step 1) Then go through all your role and perform a merge old new to bring in the new authorization objects
Just to forewarn you of a potential problem which have been encounter at the point of writing.
After updating/ modifying roles in step 2C, when going back into 2C to make sure all roles are now green, 70% have gone back to red!
The maintenance done is ok, but there seems to be a problem while trying to go back into the roles again to re-generate.
SAP recognizes them as needing "adjustment", so you cannot pick them up in mass generate in PFCG as they do not come in, even though the authorizations tab is red.
This problem is currently with SAP and it is confirmed that nothing have been done wrongly.
Generally, the work is quite manageable in the upgrade, but don't be surprised at how big the upgrade is when compared to upgrading from 46b to 46c.
If we have full software of 46c and 47E is it possible to upgrade 46c to 47E or there is a seperate 47E upgrade software need to be requested from SAP?
Where I can get the document with upgrade steps on the service market place?
It is of course possible and supported:
http://service.sap.com/inguides
--> SAP Components
--> SAP R/3 Enterprise
--> (choose your version)
at the bottom there is an "Upgrade guide" for Windows and Unix.
For Upgrades it is recommended to read ALL the notes mentioned in the
upgrade guide and to make sure one is using
- the correct version of the "tp" program
- the correct version of the "R3trans" program
- the correct version of the "R3up" program
All that is explained in the upgrade guide and in the corresponding notes.
If this is your first upgrade you should take a person, that has some experience on doing that for the first time.
Installation of SAP R/3
Currently we are going to install SAP on a new IBM server from the existing COMPAQ server. Where can I get the steps for that.
Configuration is :
   OS - windows 2003 server
   DB - Oracle 9i
   SAP 4.7
http://service.sap.com/instguides
--> SAP Components
--> SAP R/3 Enterprise
--> SAP R/3 Enterprise Core 4.70 / Ext. Set 2.00 (SR1)
--> Inst. Guide - R/3 Enterprise 4.7 x 2.00 SR1 on Win: Oracle
The above url is the SAP Service Marketplace with all the information you need to install, configure and run system. You need to be a valid licensed customer with a user ID and PASSWORD to use that.
Without access you won't be able to successfully run any SAP systems because it has notes, patches etc.

http://www.sapmaterial.com/tablecontrol_sap.html
Custom Controls
A custom control is an area on a screen. You create them in the Screen Painter, and, like all other screen objects, they have a unique name. You use custom controls to embed controls. A control is a software component on the presentation server, which can be either an ActiveX control or a JavaBean, depending on the SAPgui you are using. They allow you to perform tasks, such as editing texts, locally on the presentation server. The control is driven by the application logic, which still runs on the application server.
The SAP Control Framework
The controls on the presentation server and the ABAP application programs on the application server communicate using the Structure link SAP Control Framework. This is programmed in ABAP Objects, and contains a set of global classes that you can find in the Class Browser under Basis ® Frontend services. These classes encapsulate the communication between the application server and presentation server, which is implemented using Remote Function Call.
All application controls are encapsulated in a global class. You can find the SAP Basis controls in the Class Browser under Basis ® Frontend Services or Basis ® Component Integration. Programs that use controls on a screen work with the methods and events of the global classes that encapsulates them.
Container Controls
Before you can work with a custom control on a screen, you must assign a Structure link SAP Container Control to it. Container controls are instances of special global classes from the SAP Control Framework. The global class for custom controls is called CL_GUI_CUSTOM_CONTAINER. To link a custom control to a container control, pass the custom control name to the CONTAINER_NAME parameter of the container control constructor when you instantiate it.
As well as using custom containers, you can link controls to a screen using a SAP Docking Container. This is encapsulated in the global class CL_GUI_DOCKING_CONTAINER. The SAP Docking Container does not place the control within a screen. Instead, it attaches it to one of the four edges. You can nest containers. For example, you can use the SAP Splitter Container (classes CL_GUI_EASY_SPLITTER_CONTAINER or CL_GUI_SPLITTER_CONTAINER) within other containers. This allows you to split a custom control or docking control into more than one area, allowing you to embed more than one control.

Differences between 6500-E and 6500 chassis?

Can someone please provide a link to a Cisco url/document describing the differences between the 6500-E and 6500 series chassis? I've heard references to an increase in backplane/switch fabric throughput and also an increase in number of POE devices supported but nothing that can be verified on the Cisco site. Thank you in advance.

Long,
I have not seen a specific document that compares the 6500 and 6500-E Chassis.
The only major difference between the 6500 and 6500-E Chassis is the 6500-E series switches offer enhancements to scale beyond the 4000W power supply. The 6500-E provides higher density PoE deployments that require more power than the original 6500 chassis can deliver. My undertanding is, there is no difference in backplane throughput between the 6500 and 6500-E Chassis.
