About application server

Hi All,
I created a log file in application server, but lot of dump created in the file(very big file).
I am using Delete dataset <filename> ,but that file is not deleting.
Please help me.

check if sy-subrc = 0.
after delete dataset statement.
First you open dataset for input which will retun sy-subrc if the file exists.
then proceed for delete dataset

Questions about application server architecture

Hello guys,
I have few questions about application server architecture�
I have a task to build a server application which will do the following: Clients (special java clients) will connect to it and send some data for further processing on server side. Chunks of data will be relatively small but they will take a lot of time for processing (it is ok that it will be quite slow).
Also server will run some sort of �database� where all clients� working data will be stored. So, in case a client loses its data he/she is always able to download it from the server.
For me it seems, like server will consist of the following components:
1. �Reception�. This part will be responsible for all client-communication procedures.
2. �Data storage�. This part will simply store all clients� data and provide some API interface for clients through �reception� to manage it (add/get/delete and so on).
3. �Processor�. Some sort of dummy-sophisticated module. It will take some input data from �data storage� when it receives order for this and process it. �Processor� will have two states: �busy� which means �processor� processing some data and �available� which means �processor� ready to process new data.
4. �Manager�. This part will always check �data storage� for new data and �processor� for availability. When �processor� and new data are available �manager� will make an order for �processor� to take new data from �data storage� and process it.
So, my question is the following: Which technology and approaches I should use to realize my plan?
I think that I can make �reception� as a Session Bean, but I don�t know yet, what are the best for the rest, for example �manager� and �processor�. I was thinking about writing my own application server (and I can do it), but I would like to learn j2ee technologies, so I think it is a perfect chance for me (I read a lot about j2ee before I wrote this post, but all examples have only �account�-�bill�-�money transfer� I think it is quite far away from reality or I am doing something wrong ;-)!
p.s. I am thinking about using JBoss as an Application Server. I tested it and wrote some tests. They work and run fast enough, so I like it. Moreover it has module architecture.
Please, give me some advises and tips!
Thank you in advance!

1. �Reception�. This part will be responsible for all
client-communication procedures.Session bean with remote interface.
2. �Data storage�. This part will simply store all
clients� data and provide some API interface for
clients through �reception� to manage it
(add/get/delete and so on).Session bean that will use entity beans or hibernate to work with persistant data.
3. �Processor�. Some sort of dummy-sophisticated
module.Use a message driven bean. Make Reception to enqueue a message when new data is available for processing. Processor will process the data and store the resut in database using Data Storage session bean.
4. �Manager�. This part will always check �data
storage� for new data and �processor� for
availability. When �processor� and new data are
available �manager� will make an order for
�processor� to take new data from �data storage� and
process it.It's redundand component, because application server will manage messages and processors.

I need information about Application Server Features

I am looking for detailed information regarding what the Application Server offers and what are the possibilities, both Technichal and Business related. I have looked at the oracle web-site. But information seems to be scattered in multiple pdf and other documents. Is there a better source for the information?
Thanks

Hi,
You can have a look at the Oracle Application Server Concepts 10g Release 2 (10.1.2) - it details the Technical & Business possibilities to a reasonable degree :-

About application server flat files

I am comparing flat file with database table the flat file is in application server .flat fiel width is some 50000+records.I am executing the program it is continuously keep on executing i waited upto 5 hours still it is executing can u plz help me how to execute the report.

Hi Pranitha
I guess it will be better if you can post your code to identify if the problem is with the code or with the database.
Alternatively, you can do below steps to identify whatz happening in the background.
1. Go to Transaction SM50.
2. Select the process(check box) where your job is executing.
3. Use Menupath: Program/Mode -> Program -> Debugging.
By doing this it will open a new session in debugging mode of your current execution. Maybe by doing this it might help you identify if there are any problems like the index of the loop, no of records extracted from file, no of records from table...
Hope the above info can lead you in resolving the problem.
Kind Regards

My Application Server has installed Win2003 .
Do i must install windows terminal server on the Win2003 if i want to run window application?

Yes, you would need to have Windows Terminal Services enabled on the server first.

Interface: it is a program that performs communication with External system from SAP.
There are two types of interfaces:
1. Inbound Interface: External system sends the data to SAP
2. Outbound Interface: SAP sends the data to External system.
Let's take a scenario:
There are two Systems SAP ERP and Seibel CRM
Scenario1: Whenever an Order is created in Seibel CRM system it has to be transferred to SAP where the Order confirmation, Delivery and Billing will be performed. This can be enabled by using IDOC as inbound interface.
Scenario2: Whenever a New customer is Created in SAP ERP this customer data has to be transferred to Seibel CRM using Outbound IDOC / RFC.
Basically interfaces are implemented using RFC, BAPI, ALE/IDOC.
INTERNALLY SAP IS 3-TIER ARCHITECTURE

Installation of forms reports and oracle application server 10g

Hi,
I have been using client server till now, now planning to move to 10g. Got the developer suite 10g.
Tell me how and where to install forms/reports and Oracle application server... I mean forms reports should be on developer PC then what about application server? should it be on a different dedicated server? or can i have it on database server?
in case, if I install application server on one server and database is on another server then what about forms and reports?
please tell me which is the right option?

please tell me which is the right option?Ideally, you should have two separate server machines.
One for the database server.
One for the Application Server.
The Application Server is basically used for hosting your forms and reports, so you dont have to place the forms and reports on the developer PC or at any other server.

Adding another application server.

Hi Experts,
My company is having 2 system landscape.
DEV & QAS in one and PRD in one server.
in recent years, my company is growing faster.
i.e increasing number of End users and database growth.
and now the task is to add 2 or more application servers.
my doubts about application server are as follows:-
1 *Deploying application server means is tht installation of sap central instance in
new server or installing an Dailog instance ?
2 *How to add new installed application server to the existing land scape ?
3 *how to group up the added application servers in to a group , so that the
user will get connected to sap by tht group of application server?
requesting you to give some inputs on adding new application server and
solution for database growth ?

Hi graham,
You mean to say, if i install Dailog instance in new server and connected to lan with same ip class as PRD server. that will appear in SMLG.
so, there is no concept of selecting new server from PRD. i.e by STMS router or RFC .
and after adding the new application server i can create new group in SMLG
(by combining all the application servers, so tht user logons will be distributed.)
is that right.
if any RFC connection has to maintained from PRD to new application server.
please let me know that.
thanking you

Application server architecture 2

Hello guys,
I have few questions about application server architecture�
I already was asking similar question (http://forum.java.sun.com/thread.jspa?threadID=654898) and got few replies which were looking for me quite ok, but after reading more docs I doubt that suggested approach is right.
So, I have a task to build a server application which will do the following: Clients (special java clients) will connect to it and send some data for further processing on server side. Chunks of data will be relatively small but they will take a lot of time for processing � up to one or two days.
Also server will run some sort of �database� where all clients� working data will be stored. So, in case a client loses its data he/she is always able to download it from the server.
For me it was seeming like server will consist of the following components:
1. �Reception�. This part will be responsible for all client-communication procedures.
2. �Data storage�. This part will simply store all clients� data and provide some API interface for clients through �reception� to manage it (add/get/delete and so on).
3. �Processor�. Some sort of dummy-sophisticated module. It will take some input data from �data storage� when it receives order for this and process it. �Processor� will have two states: �busy� which means �processor� processing some data and �available� which means �processor� ready to process new data.
4. �Manager�. This part will always check �data storage� for new data and �processor� for availability. When �processor� and new data are available �manager� will make an order for �processor� to take new data from �data storage� and process it.
I got few suggestions:
1. Make �Reception� stateless session bean. I agree with it. It is quite reasonable.
2. Make �Data storage� as a session bean that will use entity beans or hibernate to work with persistent data. It is also seems quite reasonable and as it was suggested I would like to implement my own data access mechanisms instead of using those which provided by J2EE server.
3. !!! �Processor�. Suggestion was the following: �Use a message driven bean. Make Reception to enqueue a message when new data is available for processing. Processor will process the data and store the resut in database using Data Storage session bean.� It is quite reasonable, except one little thing: I read that Message Driven Beans are not designed for long time processing. Moreover, for example in my JBoss server, Message Driven Beans have attribute KeepAliveMillis=30000. For me it seems that after 30 second my message driven bean will be killed by server and now I doubt: is message driven bean a good solution for implementation long time running processor?
Now I am thinking that �processor� component should run as an additional application outside of J2EE server and from time to time (when data is finally processed and �processor� available again) send messages to my j2ee server.
So, whole picture will look like this (please have a look on the picture: http://www.flickr.com/photos/77716401@N00/35565234/ ):
1. j2ee server always on and ready to create �reception� session stateless EJB to serve remote clients. At the beginning it thinks that �processor� offline and doesn�t attempt to interact with �processor� in any way.
2. When clients appear to interact with server they simply send or receive package of data without complex interaction. �Reception� simply receives data from clients, pass it to �data mapper� component and tells to �manager� that new data available for �processor� to process. �Data mapper� component stores received data in �database�.
At this point j2ee server does two simple things:
- Collecting information for further processing from remote users
- Returning backups of received information to its owners.
3. �Processor�. �Processor� talks with my j2ee application via �Manager� stateful EJB. When �processor� runs first thing it does it asks �manager� for data to process. If there is new no data to process, �processor� does nothing but �manager� remembers that �processor� is ready to work. If there is data to process �manager� passes data to �processor� and remembers that �processor� is busy.
4. When �processor� finishes processing it does the following:
a. Returns data to �manager�. �Manager� passes processed data to �Data Mapper�. �Data Mapper� stores processed data in database.
b. Asks �manager� for new data to process if there is new data to process, �processor� does nothing but �manager� remembers that �processor� is ready to work. If there is data to process �manager� passes data to �processor� and remembers that �processor� is busy.
5. When client submits new data �reception� tells to �manager� that new data available and it �processor� state is �ready for work� �manager� sends order to process to processor.
And so on. Now for me it seems quite reasonable architecture.
But, since I am very new in j2ee technologies I ask few questions:
1. Is my approach right at total?
2. Is it ok that I would like to make �Reception� stateless EJB, �Data Maper� BMP EJB and �manager� stateful EJB?
3. I know that JMX is a basic concept of J2EE, so I would like to register my database as a resource in my J2EE server. Is it right?
4. I need some sort of component which runs all the time from time server started till it is off. If there is anything like this?
Please, give me some advises and tips!
Thank you in advance!

No, this is really nothing more than an introduction for people that have never seen a SAPgui screen before. Most ABAPers can skip right over this course. If you understand the NetWeaver architechure, then I would suggest to start withe BC400.

Question about the choice of containers of the J2EE application server

Hello,
I need to be clarified about the J2EE technology. After read some documentation about J2EE, I saw that it is possible to use different kind of containers in order to develop a J2EE application.
Actually I use an application server (JONAS) with tomcat embbeded so I develop my application that is composed by EJB and servlet. So when I build and deploy my application at the end I have got a .ear, and everything works well.
But my questions are:
1- If I installe a J2EE server where a web server (Tomcat or another) is already installed can I use this web server as my web container.
2- If it is possible how can I indicate to my J2EE server that I want to use this web server as a web container?
3- And for my application does the .ear will work or do I have to split my entire application in .jar for the EJB and .WAR for the servlet.
4- My last question, how my .war and .jar will know that they have to work together, in fact do I have to precise a link between them if yes how?
Thank you very much for any information

1. Every J2EE server must have a web container, so one will always be installed. As long as you write a compliant .war that is deployed either stand-alone or as part of an .ear, you can be guaranteed it will deploy and run.
2. The fact that you are deploying a .war or an .ear that contains 1 or more .wars is enough for the J2EE product to know you need to run the web-application on the web container. Many people uses the terms
web server and web container interchangeably. Often people are more likely to use the term web server if it runs as a separate process. If it helps, you can think of the J2EE web container as being an implementation of a servlet and jsp container that runs on top of a regular HTTP engine, but J2EE vendors don't necessarily have to have separate products for each.
3. You can either deploy a standalone .war or embed 1 or more .wars within an .ear.
4. The fact that you have a .war and an ejb-jar within the same .ear tells the application
server that they're part of the same application. If you need to talk between your web application
and the ejb, there are number of ways to express that dependency. E.g., if you want to invoke on
an ejb through its Remote client view, you would define an ejb-ref in the environment of the web-application.

About Oracle Application Server 10.1.3.1

Hi friends,
I got a software and in its installation guide, it says the software supports Oracle Application Server +10.1.3.1+.
How could I find where to download a pure Oracle Application Server 10.1.3.1 rather than the SOA suite. The suite is very large and slow. There're many components such as ESB,BPEL,Process Manager which we don't use. But It seems to me I can not find the standard Oracle Application Server 10.1.3.1.
Would anyone kindly help me about this?
-Ricky

when you start the application, you will have to choose the version that not include SOA, for this you will nead a database, if you dont have it you wont be able to install, and if you dont want it, in the installer, you will be ableto choose versions, choose between those that don't include SOA, SOA is 1 of 4 options.

Need help about Oracle Application Server Terms

Is Oracle Application Server called Weblogic Server?
What is the difference between it and the HTML_DB or Application Express? are they the same? Can all run JSP? and what other supported languages?
I am just little bit confused about those terms(Middleware, Application Server, HTTP Server, HTML_DB, Application Express, Oracle Fusion)
Would appreciate if someone can explain them briefly with examples for getting more clear.
Thanks.

The name of this forum is "Installation." What does your question have to do with installation?
Information on Oracle's strategy for replacing the 10g App Server code line with the BEA WebLogic code can be found by going to http://otn.oracle.com and searching for information on Middleware Strategy.
This forum is not an appropriate place to answer your other questions either: Use google.

What do you think about IPlanet 6.x Application server?

Hi,
Right now our company is developing an important project with J2EE. Our customer has IPlanet 6.5 application server. So far, we have had lots of problems with it.
What do you think about it?.
Would we consider to change the application server?.

We also have had a lot of problems, although to be fair we have got it running reasonably reliabily now but only after disabling some of its features such as clustering. Make sure you have the maintence pack 1 installed. Ask Sun about the problems you are having often we would get a reply saying it was a known bug etc, unfortunatly no bug list is made available by sun...
