Accessing a database in dynpro

Hello,
I'm new to dynpro. My requirement is to access a database ( MaxDB or Oracle ) through dynpro application. The database is present on WAS.
I have to fetch data from database & display it in dynpro interface. Also update to database by entering data through dynpro interface should be possible.
Is direct access to databse in dynpro possible? Any solution to this?
Thanks

Hi Prasanna,
You can also check the tool which will create Java classes for the tables in Database.

Can I use web Dynpro to access other database

Hi Experts,
Can I use web Dynpro to access other database? Like we have a Siebel Database, can web dynpro application read data from there? If yes, How can I do it?
Thanks a lot!!!

Hi,
I think you should be able to write Native SQL in the supply function or the methods of the Assistance Class.
Hope this helps.

<snip>The subject of this forum is Oracle databases. How does your problem relate to that subject?
Two bits of advice:
1) Make sure you ask questions in a forum related to your problem.
2) If you want to be taken seriously as a professional, drop the MS IM Speak and use the language of the forum. In this forum it is English, which is successfully used by many people for whom English is far from their native language.

An error has occurred while accessing SQL database or system resources. If this is the first time you have seen this message, please try again later. If this problem persists, please contact your administrator.

I have SP Server 2010, and when I try to DELETE a rule within an existing Audience, "Property (Account Name) = domain/username", I get this error, "An error has occurred while accessing SQL database or system resources. If this
is the first time you have seen this message, please try again later. If this
problem persists, please contact your administrator." When I try to "MODIFY" the rule I get this error, "One or more values typed on this page are not valid. Check the text for the indicated fields."
The last time I checked it was working, I'm not aware of any new updates installed recently? I did a full Profile Synchronization as well, but still not working, please advise? -- Evenstarline

Hi Sara,
First of all thank you very much for your prompt responses. Here are my comments to each of your suggestions below, and just to let you know I am using a Farm Admin account.  I
was able to do this way after we upgraded from SP 2007 to SP 2010 as well.   I would like to mention I'm not a SP expert, just been given the responsibility due to another person handling it just left, so apologize with some of
my novice questions below?
1. When I change the Operators to "Contains" or "Not Contains" get generates this error below.
     Error generating in red towards top of the audience page..."One or more values typed on this page are not valid. Check the text for the indicated fields."
     Error occurred where you enter your "Value"..."Could not resolve the user identity. Please re-enter the account name."
2. We have a 3-server-tier topology (SPWeb, SPDB, and SPFarm). Does the updates only apply to where the Central Admin is installed, which is the "SPFarm"? I checked all
3 servers, and NONE of the updates (KB2899494, KB2889845, and KB2883055) you'd mentioned are installed.
3. I'm new to IISRET, I need to be extra cautious of what I run in production, is this safe to run with no problem? What does it do? And How do I run it?
4. I'm also new to viewing the ULS log. I'd just downloaded a viewer for it. I'm assuming the only logs I need to be concern with viewing are within the SPAdmin (where Central
Admin is installed)? There's so many of them, what should I be looking for exactly?

How to access multiple database present in single instance

Hi Team,
In oracle 11.2, can there be multiple databases in an instance??? In one of our environment, I could see multiple databases in an instance. Could you please help me in giving the data dictionary or query to access those databases?
Actually, querying v$database, I could see only one database which is same as instance name. But in inventory, there are multiple database in an instance?
I am still not exactly clear about this. Can someone help me with this?
Thanks!
Vidhya

In Oracle one instance manages one (1) database. A database consists of multiple *schemas*.
Other vendors erroneously call a schema 'database'.
So, no, you didn't see multiple databases.
There is also one datadictionary, consisting of a set of views.
All views beginning with dba_ list the entire database, all schemas.
All views beginning with all_ list the objects you have access to.
All views beginning with user_ list your own objects.
The view DICT show you the contents of the datadictionary.
Oracle also has online documentation at http://docs.oracle.com
From your question it is clear you should read the document called the 'Oracle Concepts Manual'.
You can find all documentation for 11gR2 here Oracle Database Online Documentation 11g Release 2 (11.2)
Too many people here don't make any effort to read it. This is probably the reason why you got no response.

Not able to access the Database & Clusterware from OEM Console.

hi,
I had installed Oracle RAC 11g R2 in RHEL 5.3 Operating environment. I had installed my Oracle RAC with Enterprise Manager Console.
Its with the defailt port 1158. After the installation when i try to access my EM Console, i was not able to access the Database and Clusterware from EM Console.
When i access the EM console with url, I found with Startup and Perform Recovery option. But whereas my database is already startup and running.
So when i click startup its saying database is already started. Since it is a prodution environment i dont want to go with Perform recovery option.
Please tell me hw to attach files in this thread so that i can send the snap shot of the console for your reference.

hi,
As mentioned due to not having the default listener port 1521, we are facing this problem.
As meniotned i had changed the emoms.properties file and changed the port and my emctl page is opening.
But am not able to access the other parameters like ASM, Servers, Clusters etc bcoz since in some file it is looking for 1521 default port.
So is it better to go for emctl deconfig and config again or to change the port the files which required.
If i do in what are the file the default port will be located related to emctl.

"Failed to retrieve data for this request" occurred when I tried to access a database.

Hi,
I installed the sql server 2008 Client on my pc, so that I can connect to a remote sql server 2008 Enterprise cluster. Here is what happened:
0. Added myself as a db_owner on the two databases in the sql server cluster.
1. On my windows xp pro, I typed the server name and log in.
2. After I logged in, I clicked on the Databases to expand the node. However, an error prompt says,
"Failed to retrieve data for this request. (Microsoft.SqlServer.Management.Sdk.Sfc)
The server principal "DomainName\MyName" is not able to access the database "DevicelockDB" under the current security context. (.Net SqlClient Data Provider)"
I only need to connect to two databases that I created on the sql cluster. I don't know why the DevicelockDB is needed before I can access two databases. What does DevicelockDB do? Do I need it for connecting to a database? Let me know, thanks in advance.

I had the same problem , this one resolved the problem , thank you deshmukhsdineshd

Trying to access 10gr2 database from sqlplus utility but it connects to 11g

Hi All,
I am facing below issue while access 10gr2 database from sqlplus.
I am having two oracle homes on one server one belongs to 11gr2 and another belongs to 10gr2.
I want to access a 10gr2 database through sqlplus utility.but instaed of connecting to 10gr2 it is connecting to 11gr2 after I enter a user name and passowrd.
I have set all the env variables such as oracle_home ,oracle_sid and path with respect to Oracle 10gr2.
Can you please let me kno what I need to do to connect to 10gr2 database and not 11gr2 database through sql plus.
Let me know if I need to give any more details on this.
Best Regards,
Dipti S

Hi Rocky,
I got the resolution.
I made a mistake by creating an oracle instance/service(e.g. fsdmo) when Oracle_home was pointing to 11gR2 Directory.so that service was refering to 11gr2 oracle home.
hence when I was setting oracle_sid(fsdmo) and trying to access database instance from 11g sqlplus utility ,it was directing to 11g and not 10g since oracle service was pointing to 11g.
So now after chnaging the oracle home directory to 11g,I am creating a service and its working fine.
thank you so much for responding.
hope I am clear with my reply.
Best Regards,
Dipti S

The server principal "XYuser" is not able to access the database "Ydb" under the current security context

SQL2005 on winserver 2003. I have a view in Xdb that accesses tables in 2 different databases (Xdb and Ydb) on the same server. I have mixed mode security. I have a SQL user (XYuser) that has read access to all tables and views on both databases, yet when I try to access the view using a C# windows application I get the following error:
The server principal "XYuser" is not able to access the database "Ydb" under the current security context
This same scenario works under SQL 2000. I looked through the postings and tried to set TRUSTWORTHY ON on both databases but that didn't help. I can access any other views or tables on the SQL 2005 server, just not the one that joins the tables cross databases. Any help is much appreciated... john

This appears to be a Login/Database Mapping issue. I was having this problem, but was able to resolve it as follows:
Using the SQL Server management Studio:
In the Object explorer, under the SERVER security folder (not the database security folder), expand Logins.
That is: ServerName -> Security -> Logins
NOT: ServerName -> Databases -> DatabaseName -> Security -> Users
Select the Login that is having the troubles. Right click on the Login and select ‘Properties.’
The ‘User Mapping’ page should list all databases on the server with a check mark on the databases that the Login has been mapped to. When I was getting the error, the database in question was not checked (even though the Login was assigned as a User on the database itself). Map the Login by checking the box next to the database name. Set the default schema. Then select the roles for the Login in the Database role membership list box. I selected db_datareader and public. After clicking OK to save the changes, the problem was resolved.
In order to ‘Map’ the Login, the Login must not already be as User on the database, so you may have to go to the database security (ServerName -> Databases -> DatabaseName -> Security -> Users) and delete the Login from the list of database Users before mapping the Login to the database.

SQL Developer 1.5.4 failed to migrate MS Access 2002 database

Hello,
I tried to migrate a MS Access 2002 Database to Oracle.
Migration of tables failed in both ways:

Error #5 - XMLExporter - Ungültiger Prozeduraufruf oder ungültiges Argument c:\Access\Stammdaten_Beton_test.mdb Database Schema Export did not complete successfully.

When using quick migration wizard also an error "Ungültiger Prozeduraufruf oder ungültiges Argument" is raised after Access starts.

Any ideas?

Logical database vs direct access of database table

Hi
I have created a FI report. I am trying to get data from large FI tables like BSAK, BSEG, BKPF, RSEG. eventhough there are 10 records as per my criteria, system is taking morethan an hour time even in background processing. This may be becaz of lot of conditions that I am applying to filter the data. But still trying to improve the performance
For fetching data which is the better way for getting optimum performance of the report.
a) directly fetching data from database tables
b) using logical database collecting data into an itab

If you are accessing the database tables more than once with different criteria then definetly it will take more time. In such case write only one Select statement on the table and get all the required data into an internal table and then process this internal table as per your logic.
Use of LDBs is definetly faster but filter conditions might not match with your filter conditions. In such case direct access of database table is preferable but as i said in above paragraph.
thanks,

Accessing shared database throws exception from one of 2 web roles

Setup:
Shared database
Main site and "admin site" each using separate web roles accessing shared database.
I had things working and running correctly until about 2 days ago. Then, only the "admin site" stopped working. I am using the same code to access the database across both sites but am getting the following exception when trying to access the
database in the admin site:
Message: Unable to open connection to "Microsoft SQL Server, provider V2.0.0.0 in framework .NET V2.0".

NOTE: I've tried to go to the v4 provider but get the same error (except with v4 in place of v4). I would suspect something amiss with my application if I didn't have a working one using shared code...though I'm still not ruling out that I'm doing
something wrong, just waiting for input from here.
Thanks in advance.

Hey there, and apologies for the lack of response. Are you still having this issue and still needing help? If so can you tell me a little more. Where is the application running (web/worker rolls)? what are the details on the SQL Database?
Thanks Guy
