9iAS: Programmatically change data source for Java/J2ee bc4j application

Background: We obtain a copy of our customer's live data daily for support issues. We'd like to be able to keep up to date as possible and get files early in the morning. due to the size of the database, it takes a few hours to download and import into our Oracle database. what I'd like to do is use two different schemas/users for the data, alternating on each day so that the loading of one, does not affect the running of the other. To make this seamless, I'd like to have a script perform the changes after the download and restart the server. The issue is how/where to change the data source so that my application will pick it up each time? I'm using an application specific data source from EM.
Any ideas?
Thanks,
Jeff

If it is intended to be accessible from Reports servlet then you can use "ssoconn" command line option where by the user name and password is stored in OID (Oracle Internet Directory)
Pls see publishing reports to web document --> command line options -> rwservlet

Changing Data Source for command objects

Hi,
My report (designed in CR 10) is running based on the Stored Procedure call using a command object; which is running successfully in the DEV environment. The report data source connectivity is a DSN.
Now i want to switch it to QA environment with different DSN name. When i tried to update the Change Data Source option, it doesn't allows to update the existing command with a new command!!!!
I don't know how to fix this. Could any one of you have idea, pls. share it here???
Thanks

If you have same table structure in new data source then you can change the datasource connection.
Follow the steps in this article
KBase Article ID:c2016958
Article refers to:Crystal Reports 10
Symptom
In Crystal Reports (CR) 10, can you change the database connection of an existing command object to use a different database connection without the use of a Crystal Repository?
Resolution
Yes, you can change the database connection of an existing command object to use a different database connection without the use of a Crystal Repository by using the following steps:
====================
NOTE:
You must apply the CR 10 Monthly Hot Fix (cr10win_en.zip) and the CR 10 Database and Export Drivers Monthly Hot Fix (dbex10win_en.zip) before starting the steps below.
You can download these hot fixes at http://support.businessobjects.com/search
====================
1. Open a report with a command object.
2. Go the 'Database' menu and click 'Set Datasource Location'.
3. In the 'Set Datasource Location' dialog box, select the connection for the command object (the connection appears as a cylinder with a plug).
4. In the lower window, select the new connection and log on to the database.
5. Ensure the connection is highlighted for the command object in the top window, and the connection is highlighted for the new command object in the bottom window.
6. Click Update.
The database connection for the command object now changes to use the new database connection information.

Raghavendra

Change Data Source for a lot of Crystal Report

I have a lot of reports which use Visual FoxPro as datasource. We will mirgrate to MS SQL Server and change the names of tables. Is there any way to set data source to new table in new ODBC other than do it manually ? Please advice.
Thanks.

Hi Leo,
If you use Business Objects Enterprise, then you can use a tool called 'Schedule Manager' to update the datasource of all your reports to SQL Server - at one go!
If you don't then, well, it gets laborious and you'll have to get into every single report and use 'Set datasource location' within CR.

Setting a session via post data on a Java/J2EE server application

Hi.
I can't seem to find anything like a Session.getSession(String sessionId) method, nor can I find anything like a request.setSession(HttpSession) method. Is there any way I can get ahold of a session object by ID rather than relying on the HttpServletRequest object to automagically give me the session object it thinks I want?

HttpSession is directly tied to Session.
HttpSessionContext is there but is depricated now:

Trying to change the data source for a Crystal Report.

The method below represents my best attempt to programatically change the data source of a Crystal Report. The goal is to have a routine that will update the data source for reports after they have been distributed to production servers. So far I have not been successful in saving the report back to the CMS. No exceptions are thrown, but when I view the Database Configuration of the report in the CMC nothing has changed.


Am I missing a step, or is there another way to accomplish this?


Thank you.

Justin,

Thank you for the reply. Time constraints have not allowed me to post back to this tread
till now. I will try your suggestion. My assumption is that Save the report back to the
info store refers to IInfoStore.commit(IInfoObjects).


I'm afraid that I do not understand why I don't want to change the report client document,
or why successfully exporting the report with the new login/password is not what I
want to do. Any explanation on that statement would be appreciated.


I did find a way to accomplish my goal. It involved adding the SSOKEY property to the
logon property bag. Below you'll see my revised code which modifies the report logon and
server. I have no idea what
this does, and SAP support has not been able to tell me why it works. However, what I
discovered is that if I changed the report option, Database Configuration -> When
viewing report:, in the CMS to Use same database logon as when report
is run from Prompt the user for database logon, then the
SSOKEY property had been added to the logon property bag having an empty string as its
value. This allowed me to successfullyupdate and save the modified logon back to the CMS.


So I took a chance and added code to always add the SSOKEY property with an empty string
as its value, and I could then successfully modify and save the report's logon info
and server. Again, I don't know what this means, but it has worked so far. If anyone has
some insight or comments, either are welcome. Thank you in advance.

How to change the jta-data-source for projects in EJB 3

Hi all,
Sorry my english! :)
I'm learning the EJB 3.0 and I'd like to change jta-data-source for projects in JDeveloper 10.1.3.1.
I explain:
In the same Application, I have a project with all Entitys and Session Beans. At the moment, the persistence.xml file is there with the jta-data-source tag.
I make a new project with JUnit (Cactus) for test the EJB's that I'd like jta-data-source reference the test database.
I make another project, with Servlet/JSP/JSF that use EJB's with interface and I'd like jta-data-source reference another database.
What kind of changes (workaround) I could make to solve this problem?
Thanks a lot!
Luciano

Hi,
There are COOM data source which may suits your needs.
please check data source

Are Multiple (Concurrent) ABAP Data Sources for AS Java UME Possible?

Hi All,
We have a solution which is using a JAAS logon module for partner authentication. for reason's I won't go into we have decided that it is best to use an ABAP data source. We will also be using the same JAAS approach for other ABAP applications in the future. Ideally we would configure the same JAAS server to use ABAP UME data sources from ABAP server 1 and ABAP server 2.
I see there are provisions in the documentation for multiple UME data sources of different types but it doesn't clearly say about different concurrent data sources. IS this even possible? If so is it wise?
Thanks,
Doug

Julius,
Thanks again for your reply. This is confusing. We have an existing .Net logon application where we centrally administer accounts and where users log in. On successful login they are issued a .net Auth cookie. Our JAAS module takes that cookie, does a web service call back to .Net and authenticates them. So authentication is done on the basis of the .Net cookie, not the java UME. We simply need a java ume to allow users to execute the application that invokes the JAAS module. The application invokes the JAAS module and if they successfully authenticate they are forwarded to the requesting SAP application. So the JAAS ume is really just needed to allow various users to run the JAAS invoking application starter. Ideally we'd use the same starter application for users of SAP Application 1,2,3, etc.
So that's where the question came from on multiple ABAP UME data sources for a single Java instance.
Hope that makes sense. Regardless the answer I guess is not possible but you see the method to our madness. And yes it is madness.
Thanks,
Doug

Data source for reports

hi all,
we r using 10g application server along with the reports service to deploy J2EE application
The data source for the application is specified using the JNDI lookup
Is it possible to use the same strategy for reports as well.
i.e., we are using jdbcpds. so is it ok if i give the JNDI look up name as P_JDBCPDS
If not is there any other way to make the P_JDBCPDS connection generic, so that i can change the username and database name without having to change the cgicmd.dat file
Any help is greatly appreciated.
Thanks & regards,

Unable to generate "Export data source" for Master data infoobject

Hi Gurus,
I'm in BW 3.5
I need to generate "Export data source" for a master data info object.
I followed below steps:
I ticked the checkbox "Characterist. is export data source" in the master data Info object maintenance screen.
In the Infosource area, for the desired Infoobject --> Right click --> Generate export datasource --> a dialog box displays saying "The generation of DataSource was successful"
Problem:
Even after refreshing, etc.. I couldn't find the generated datasource 8**** for the above master data. I also tried to replicate the datasource from the myself source system, but couldn't find it even there. I don't know where the generated export data source is hiding ???
Could anyone please help ????
Thanks,
Venkat

Hi Venkat,
I guess that after creating an export datasource for infoobject this DS should appear in the RSA1-Source systems - MYSELF - datasource overview (with name starting with 8). Since it's a datamart, it should appear also as system generated infosource. And in this case you would be able to assign in URs of data target the appropriate infosource (make sure that in Infoproviders tab of RSA1 you have inserted your infoobject as a data target).
However, there are some bugs related to export data source. CHeck if you see you export data source in RSA6.
If you don't see it - consider applying OSS Note #816892 - "30BSP26: Export DS for master data is not generated".
Note #876845 - "30BSP29: InfoObject change: Export DataSource not adjusted" is also may be useful.

OIM 9.1.0.2 - Weblogic JDBC Multi Data Sources for Oracle RAC

Does OIM OIM 9.1.0.2 BP07 support Weblogic JDBC Multi Data Sources (Services>JDBC>Multi Data Sources) for Oracle RAC instead of inserting the "Oracle RAC JDBC URL" on JDBC Data Sources for xlDS and xlXADS (Services>JDBC>Data Sources> xlDS|xlXADS > Connection Poll> URL) ?
If yes, is there are any other modifications that need to be made on OIM, or just changing the data sources?

Yes, it's supported. You install against one instance directly of the Rac Server. Then you update the config.xml file and the jdbc resource in your weblogic server with the full rac address. It is documented for installation against RAC. http://docs.oracle.com/cd/E14049_01/doc.9101/e14047/database.htm#insertedID2

Using Oracle BI Server as a Data Source for Third Party Tools

I have been researching how to use the Oracle BI Server as a data source for two days now. I have not yet found a solution to my problem.
We have a remote user who is pulling data from one of our Oracle databases using automated tools. This data base is essentially being replaced by Oracle Analytics. However, we do not want this user to get at the physical tables of Analytics, rather, we want the user to be able to connect to the Oracle BI Server itself, and issue Logical SQL to pull data.
Here are the requirements which I need to be fulfilled:
1) The ability for a remote user to connect to the BI Server as a data source.
2) The remote user must be able to do this on a Unix box.
3) The remote user must be able to automate the process of issuing SQL to the BI Server. (Command line interface is preferable)
4) The solution needs to be easily implementable, that is, this solution will be implemented many times over.
I found many articles explaining how to set up a Windows box to connect to the BI Server in this way. However, these articles outline how to use tools like Excel and Microsoft Query to pull data from the BI Server. Our current user is using SQLplus.
If possible, I would like the user to continue using SQLplus as the tool for connecting to and retriving information from our BI Server. I have tested using SQLplus many different ways to no avail. I have also tried using other tools, such as Oracle SQL Developer.
Is there a program out there that will fulfill the needs I have outlined above? Or, does someone know of a way to use SQLplus to connect to the Oracle BI Server as a data source? Or, is there a series of solutions which will fulfill the needs outlined above?
Edited by: user11177366 on Jun 11, 2009 11:46 AM

I agree it would be inefficient but only because you are using OBIEE for something it was not designed to do. You are basically asking for a "DB feed" and that should designed using PL/SQL, DB Links, Web Services or whatever is your entreprise standard to send data from one system to another. Using OBIEE for this seems a bad architecture decision to me.You are correct, the BI Server is not really intended to be queried like another Oracle Database remotely. However, the reason we are trying to do it this way is twofold:
1) We want to enforce data level security.
2) The BI Server has been fine tuned for high performance.
Forcing the end users to go through the BI Server rather than directly to the physical tables or other sorts of systems built on top solves both of these issues.
I think you are wrong. I don't see why SQLPlus should be able to query the BI Server. The BI Server can sit on top of many different DBs not just Oracle, even flat files etc. So you can't really expect the BI Server to able to translate all that into Oracle SQL output so you can query it using SQLPlus. The BI Server is not an Oracle RDBMS.You're right again. The BI Server isn't an Oracle RDBMS, and I have been wanting to treat it like one. From the data I have gathered SQLPlus can't query the BI Server.
However, my research has led me to realize that the BI Server supports the JDBC API. Therefore, (I should have went down this route in the first place) one can use the JDBC driver provided by Oracle (bijdbc14.jar) to interface with the BI Server. There are many programs and applications out there that support the JDBC API and let us connect to BI Server the way we want to. Furthermore, these programs are mostly platform independent, as they are mostly written in Java.
Lastly, from what I understand the NQCMD program can be installed on any platform as well (provided by Oracle). This is another option to connect to the BI Server as well.
Thanks for your help and your comments as I went through this process of discovery.
