Application Server and Oracle Apps - basic doubts

Hello
I am pretty new to Oracle 9iAS and Oracle Apps 11i
Please clarify my basic doubts
Read that Oracle9i AS Components are :
- J2EE and Internet Applications (sub-components are Oracle HTTP Server, OC4J, Web services etc)
- Portals
- Wireless
- Web cache
- Business Intelligence
- E-Business Integration
Read that middle tier of Oracle Apps has following servers
- Web server
- Forms server
- Concurrent Processing server
- Reports server
- Discoverer server (optional)
- Admin server
My doubts are -
1. When Oracle Apps 11i is installed, Oracle 9iAS becomes the middle tier of it
Yes / No / Partailly ?
2. If partially, then only the 'J2EE and Internet Applications' component is installed
Yes / No / Partially ?
3. If partially, then Web server (Oracle HTTP Server) and Forms server come from Oracle 9iAS and Report Server, Concurrent Processing server, Admin server etc seperate components only specific to Oracle Apps 11i ?
Yes / No
Please let me know the answers with the explanation
Thanks a ton

Oracle Applications 11i uses Oracle 9iASv1 (10222, specifically) as the underlying midtier technology stack. The latest release of 11i (11.5.10), to be released this summer, can leverage specific features of Oracle AS 10g (904), namely SSO authentication and OID user management, Portal, and Discoverer. This capability will be backported to 11i releases 11.5.8 and 11.5.9, and is currently available now to limited customers through the Early Adopter program. When installed in this configuration, there is a 9iASv1 tech stack installed as part of the 11i installation, and a separate AS 10g installed for SSO, OID, Portal, Discoverer, and any other AS products the customer may be using. Aside from SSO, OID, Portal, and Disco, 11i does not yet run on other components of 9iAS or 10g (e.g., OC4J). Applications plans to move to 10g as the underlying tech stack in a future release.

9i application server and oracle 7.3.3.5

we are planning to deploy 9i application server and have an origin database(8.1.6). however we have an old database(7.3.3.5) running on IBm mainframe and I am wondering wilkl it be possible to access that database using 9i application server. if yes, pls. help.
Thanks---

We have developed several form apps using the products in
question. We have experianced minor GUI problems but many of
these had patches. You can check by going to: ftp://oracle-
ftp.oracle.com/dev_tools/patchsets/dev2k/Win95NT/2.1/
I never experianced the scroll-bar problem the first response
talks about, not saying it isn't possible. Possibly a different
database platform.
All in all we have had good luck with the applications, little
bit of a setup learning curve, but once we were up and running
we produced some very effective web applications.

What is diff between oracle application server and weblogic server?

what is the exact difference between oracle application server and weblogic application server?

The difference between Oracle Application Server AND WebLogic Server has been discussed in a lot of forums dated 2008 and earlier comparing OAS10g with WebLogic10.0/WebLogic9.2
But, now since Oracle has taken over WebLogic, this is not really important.
Now, OAS has no further releases post 10g. WebLogic Server will be the Oracle's strategic application server going forward.
So, if your query is for choosing one of them for a new environment, you are better of with WebLogic Server 10.3.6 OR WebLogic Server 12g
As we will not have further releases of OAS and also OAS10g will be end of life soon, we recommend Oracle WebLogic Server.
If you still want to know the differences, here is one such old oracle documentation link that talks about it
http://docs.oracle.com/cd/B10467_16/migrate.904/b10425/asmwl02.htm

How to setup the SMTP server in Oracle apps?

Hi,
How to setup the SMTP server in Oracle Apps? Is it mandatory to keep the SMTP server on the same host where the Oracle data base is installed? Also can someone help how we can set up the SMTP server on different host (not the Database server) and we can use the same for Workflow notification mailer.
Thanks,

How to setup the SMTP server in Oracle Apps? Is it mandatory to keep the SMTP server on the same host where the Oracle data base is installed? No, it is not mandatory. Also please note that the mails are sent out from concurrent manager mode. Not from the database node.

It depends on the operating system you are using. If you are using *nix then sendmail needs to be configured.

Compare SQL Server and Oracle syntax

Hello, I am very new to the Oracle DB as I have been working with MS SQL Server for many years. I have a SQL statement that works fine in MSSQL but seems to not work in Oracle. Is this a syntax problem or do I need to look elsewhere?
DECLARE @as_master_key varchar(26)
EXEC [dbo].[GET_UNIQUE_MASTER_KEY]
     @as_project_name = N'CMDEMO',
     @as_database_site = N'CMPL',
     @as_user_initials = N'SK',
     @as_table = N'SUBMITTAL_CATEGORY',
     @as_master_key =
     @as_master_key
OUTPUT SELECT @as_master_key as N'master_key'
This is what I use in MSSQL and it works fine - but I am porting this application to an Oracle backend and it fails. Any suggestions?
Thanks in advance to this newbie. :)

SQL Server and Oracle are two completely different RDBMS'.
You'd be best not to try and port SQL Server code to Oracle SQL or PL/SQL directly as it will not favour the power of Oracle's features correctly.
I'm not sure what your code is supposed to be doing (I find SQL Server code awful to read, and never understand the need for "@" before variable names, that just seems to show a lazy parser (or lazy coder who designed the parser)).
From what I can guess it's going to be something like...
SQL code...
create or replace sequence my_master_key;PL/SQL code...
DECLARE
as_master_key number;
as_project_name varchar2(20) := 'CMDEMO';
as_database_site varchar2(20) := 'CMPL';
as_user_initials varckar2(5) := 'SK';
as_table varchar2(30) := 'SUBMITTAL_CATEGORY';
BEGIN
select my_master_key.nextval
into as_master_key
from dual;
-- In 11g you could replace this select with just:
-- as_master_key = my_master_key.nextval;
END;This get's a unique sequence value into a variable and declares all the other variables. What you want to do with them after that I don't know.

Difference between Oracle Application Express and Oracle Forms/Reports

hi guys,
i have just use oracle apex to create some report generation tools through the web. know that this is what is known as html db in the past.
however, i have not really touch oracle forms and reports before, neither have i really seen how they work.. but soemhow i feel oracle report/forms seems to be more.. then this oracle apex.
it includes integration with web services, java and pl/sql .
but i still cant really figure out what is the actual general main difference ?
is it that for oracle forms there can be some programming logic inside , whereas for apex , it is just using what is available from what oracle provides ..
i am read oracle form white paper, but seriously, i am not a very web guy. it has alot of components that i am not familiar with.
so i hope you guys can just give me a more general rough idea.
regards,
Noob.

Hi, my .05$
... most Forms & Reports users will tend to be old installed base customers using applications developed many years ago in F&R such as insurance company cores and even banking cores. Going from client/server F&R6 to "web" F&R10g is costly as you have to license an application server and most likely need to migrate to recent versions of the DB in case the customer is still on oracle 8 (common occurrence). So many customers opt. to not migrate or to simply invest in new web enabled solutions.
Using the migration tool f&r installed base will have an easier job of migrating and at a price of whatever DB edition they are using and probably be able to do it with the same people who maintain their f&r systems provided they learn a bit about web technologies.
what might be interesting to see is performance perception of users on f&r vs. apex...

How to pull all the txt files from an application server to oracle server

hi
i got some 30 txt files on java application server. i have two questions
1) can java guys will be able to move those files to some oracle directory that will be used by create external table command.
2) can oracle do that using a stored procedure ..but then for it i think i have to create ftppkg and ftpbdy and call and connect each time...
which one is better and why?
regards
raj

Hi,
You can create procedure to move file from application server to oracle server.
Code for list all files in directory
ops$tkyte@8i> GRANT JAVAUSERPRIV to ops$tkyte
2 /
Grant succeeded.
That grant must be given to the owner of the procedure.. Allows them to read
directories.

What is their difference betwwen Sun ONE Application Server and J2EE serv

Sun ONE Application Server is Sun implementation of J2EE server.
But it seems even no Sun ONE Application Server, use J2EE SDK command
j2ee -verbose
we still can launch an Application Server that support EJB, JSP....
what is their difference betwwen Sun ONE Application Server and J2EE server provided by J2EE SDK ?
Thanks,

Sun ONE generally refers to the Sun ONE Application Server version 7.x. This is a J2EE 1.3 compliant application server from Sun. Sun also released a Reference Implementation version (RI) as a requirement of the J2ee 1.3 spec. This is the J2EE server you are refering too. The Sun ONE Application Server 7 is a more robust production ready App Server.
Going forward, Sun combined the 2 seperate groups to include just 1 release. The J2EE 1.4 Reference Implementation is the Sun Java System Application Server Platform Edition version 8. SJS AS 8 PE is both free and production ready. Other version will include High Availability, Managing and Monitoring features.

RE:difference between application server and web application server

hi,
i am a fresher to SAP.please tell me the difference between application server and web application server so that my doubt will be clarified.

Hi,
the SAP Web Application Server is the reliable, open standard-based application server from SAP. It supports both J2EE and ABAP, and serves as the underlying infrastructure for all new and upcoming SAP solutions, like SAP R/3 Enterprise, SAP Portal, SAP Exchange Infrastructure, and all other SAP components.
The SAP Web Application Server is not a new product, it is the natural evolution of proven SAP application server technology formerly known as SAP Basis. It provides the platform to develop, execute, and operate Web applications and Web services as well as traditional SAP GUI based applications
if it helpful rewards points are appreciated

Basically an application server has more functionality than a webserver, such as enterprise javabeans. That is assuming we are taking about a java webserver like Tomcat.

What are the commands available to read a file from application server and

What are the commands available to read a file from application server and store the file into an internal table?

Hi,
To read a file from an Application Server to an Object there is a command in ABAP called <b>READ DATASET</b>. After that file is transported to that object you have to do a loop and put that data in an Internal Table.
This statement exports data from the file specified in dset into the data object dobj. For dobj, variables with elementary data types and flat structures can be specified. In Unicode programs, dobj must be character-type if the file was opened as a text file.
For dset, a character-type data object is expected - that is, an object that contains the platform-specific name of the file. The content is read from the file starting from the current file pointer. After the data transfer, the file pointer is positioned after the section that was read. Using the MAXIMUM LENGTH addition, the number of characters or bytes to be read from the file can be limited. Using ACTUAL LENGTH, the number of characters or bytes actually used can be determined.
In a Unicode program, the file must be opened with an arbitrary access type; otherwise, an exception that cannot be handled will be triggered.
If the file has not yet been opened in anon-Unicode program, it will be implicitly opened as a binary file for read access using the statement
OPEN DATASET dset FOR INPUT IN BINARY MODE.
. If a non-existing file is accessed, an exception that can be handled can be triggered.
Influence of Access Type
Files can be read independently of the access type. Whether data can be read or not depends solely on the position of the file pointer. If the latter is at the end of the file or after the file, no data can be read and sy-subrc will be set to 4.
Influence of the Storage Type
The import function will take place irrespective of the storage type in which the file was opened with the statement OPEN DATASET.
If the file was opened as a text file or as a legacy text file, the data is normally read from the current position of the file pointer to the next end-of-line marking, and the file pointer is positioned after the end-of-line marking. If the data object dobj is too short for the number of read characters, the superfluous characters and bytes are cut off. If it is longer, it will be filled with blanks to the right.
If the file was opened as a binary file or as a legacy-binary file, as much data is read that fits into the data object dobj. If the data object dobj is longer than the number of exported characters, it is filled with hexadecimal 0 on the right.
If the specified storage type makes conversion necessary, this is executed before the assignment to the data object dobj. Afterwards, the read data is placed, byte by byte, into the data object.
