Database independant application [urgent]

Hi,
I need to design an application that should be database
independant, meaning backend could be even MS Access. What are
all the consideration one should take care off ?. Obviously, I
can't have stored procedure, then where these business logic
should reside ?, business logics can be there in middle-tier (eg.
OAS) ?.
Is there any douments available on net ?
If anyone worked these kind of application, please help me.
Thanks,

How to make an webapplication database independent.

Dear All SDN's,
I have developed an EJB appliction to call into portal.
Calling into portal is the other part of this.
But here what i want to be clear is, i have designed an webapplication which is database independent.
i.e., like, to connect to any database in SAP J2ee Engine we need to configure the JDBC Connector of Visual administrator.
I had configure the same in the visual administrator by adding an alias to the existing (System) datasource.
when i try to access the datasource from the jsp using the following line,
<b><sql:query dataSource="jdbc/ONLINE_SR_POOL" var="srtype">SELECT * FROM TMP_SR_TYPE</sql:query></b>
it returns errors. Please advise what it goes wrong. All my web pages run ok from Oracle Application Service or Sun Application Server
What do you suggest me to establish a database connection so that the JSP can query the data from the data tables? Should I use JavaBean instead of using<sql:query dataSource="jdbc/ONLINE_SR_POOL" var="srtype"> inside the jsp page?
Tell me where i am going wrong.
Your inputs will be appreciated,
Regards,
Sireesha.B

Hi,
Plz specify the errors, what r u getting and in which perspective......

Database independant ETL in ODI for SQL Server and Oracle

Hi,
We have a requirement to create ETL which can be run for both SQL Server and Oracle.
We have some tables to be filled from operational database to data warehouse using business requirement.Our goal is to create code which should be database independant.
We will provide all DB details at the start of execution and it will code for as per provided details.
The same can be achieved by Talend.
I wanted to know if same can be achieved in ODI.
Any pointers regarding this would be helpful.
Thanks,
Mahesh

A quick trick: Provide one more value at the start of execution. It is something like a flag. For example db_flag. It can be either 'O' or 'S'.
Open both oracle and sql server KM. Copy one of the KM code to other KM and put an if condition to check the flag.
if (#DB_FLAG.equalsTo("O")){
Oracle code goes here...........
}else{
SQL Server code goes here...........
Its a pure KM customization.

Webdynpro ABAP independent application

hello,
I have developed independent application of webdynpro ABAP
i want to integrate it on portal
i have page, create iview, assign application url to the iview - all this i do in portal content administration etc
but in later versions, instead of iview etc, there is bankend transaction code, ie tcode in R/3 where I can assign my web dynpro application to portal
I need the name of that transaction code. kindly help with your inputs
thanks
bhakti

Hi Bhakti,
AFAIK there is no such kind of facility available so that you can directly assign your webdynpro into the portal using any t-codes.
But the SAP Enterprise Portal supports the Web Dynpro application development with functions like:
Event handling of portal events
Navigation between Web Dynpro applications within the portal or to any portal content
WorkProtect mode
And With Web Dynpro you create interactive Web-based user interfaces for business applications. The portal allows the role-based and secure access to different kinds of information (structured or non-structured), services, and applications using a Web Browser.
For portal integration, refer the below document which will give you an idea.

Centralized Database and Application Control

Hi,
I am looking for idea to centralized control software to manage (start/stop/display status) oracle database, oracle application or other component on unix box, it become harder to manage database (i.e. which command, where is database location/server name) when in organize have lots of database/application/server/version to manage. How is it managed from other people, idea is appreciated.
Thank you.

And I assume that you are familiar with all the Enterprise Manager plug-ins that let you monitor non-Oracle systems from Enterprise Manager.
If you are looking for enterprise management software that has no relationship to Oracle, any enterprise software company is likely to have something for you. But if you specifically want to exclude Oracle's offerings I'm not sure why you would post this request in an Oracle forum. Surely, if you want to use HP software or IBM software or some other vendor's software, it would be more appropriate to post in a HP forum or an IBM forum...

How to improve database and application performance

Hi,
Any body please help me out that how can we improve the database and Application performance.

Regards,
Bhatiathere is no simple answer. There is no DATABASE_FAST=TRUE initialization parameter. There are a myriad of reasons why an application is performing poorly. It could be that the application (code and data relationships) is poorly designed. It could be that individual SQL statements are poorly written. It could be that you don't have enough cpu/memory/disk bandwidth/network bandwidth.
You need to determine the root cause of poor performance and address it. If you application is poorly designed, you can tune the database until the cows come home and it won't make any difference. If you are trying to run 100k updates per second against a database hosted on hardware that only meets minimal requirements to install Oracle ... well, hopefully you get the picture.
First, go to tahiti.oracle.com. Drill down to your selected Oracle product and version. There you will find the complete doc library. Find the Performance Tuning Guide
Second, go to amazon.com and browse titles by Tom Kyte and Cary Milsap. I particularly recommend "Effective Oracle by Design" and "Optimizing Oracle Performance", though I see a lot of new titles that look promising (I think I'll be doing some buying!)

Differences in the characterset used by the database & Oracle Applications

Hi All,
I have encrypted one column in the database using Oracle DBMS_OBFUSCATION tool package.When the same field is viewed from the application the characters appear different from those that are there in the database and also sometimes the value is truncated from the applications.
Could anyone please help me understand why it is happening.
Is there any difference in the characterset used by the database & Oracle Applications ??
Please help me ASAP.
Thanks in Advance,
Aush

What I mean by the characters displayed on the form in the Oracle Applications is different from the database value is that suppose the value in the database is 8¿x¿"h the characters(part of the string) displayed in the form are different from what is present in the database.

Failed to checkout SRService application module. Ensure your datasource name is SRDemo [case-sensitive!] and that connection settings are properly defined for a database with the SRDEMO schema installed. See server log for more exception details...
Apparently you guys have figured out a fix for this, but my command of JDeveloper/J2EE jargon is pretty limited at this point in my learning curve. (I've heard about Jndi, but have no idea what it does). Is there a statement I can add to the web.xml file that will fix this? If so, what is that statement, and where does it go in web.xml?
Thanks in advance.

Agents for database and application servers

hi all,
I have to go to a client site this week to install Gagents onto some database servers, some will be RAC and some application servers. it is on AIX. are there different agents for database and applications? In a RAC cluster do I need an agent per node?
rgds
alan

When installing agents in a cluster (read - RAC), during the installation, on one of the screens, you will have the option of picking up all the nodes in the cluster. Else, if you are using a push or agent deploy method, you just have to pass the correct flag (can't remember) and then list all the nodes in the cluster.
To your other questions, you do not need different agents for database, and app servers etc. The only time you would need different agents is when you are installing on different platforms.

MAP Database to Application Mapping

Experts,
Can MS MAP(Microsoft Assessment and Planning ) tool be used to extract database to application mapping information for an environment.
If yes, would it be able to extract info for MS Applications only or all the applications.
Thanks

Hi,
the MAP is possible to collect information from other software besides MS, for this you must install the SQL Management Studio, Connect the MAP Database "(localdb) \ maptoolkit" and execute the query.
