Emulated Data sources?

Hi experts,
What is emulated datasources , where they are used? what is the functionality of emulated datasources?
I will ASSIGN POINTS FOR YOUR VALUABLE ANSWERS.........

Hi...
You must be aware of the fact that the Data Source Concept has been changed from BW 3.x to BI 7.0.
BW 3.x data sources will use Transfer rules and update rules.
BI 7.0 data sources will use Transformation in place of Transfer rules and update rules.
Emulated Data Source :
When you install a Data source from the R/3 Source system, it will prompt you to choose between
1. 3.x Data source
2. Data source (means BI 7.0)
Here you have to choose 3.x Data source.
If u right click on this data source you will have the Option to create transformation etc..
This feature is called Emulated data source.
Advantage: it allows to the use the 3.x data source as BI 7.0 Data source before actually migrating.
Cheers....

Emulated or non emulated data source ?

Hi All,
We are in the process of moving our application code from JDBC to Toplink. As we are in this process , the application code is a mixture of Toplink and JDBC calls (some individual method also mixture ). We are using External Transaction Controller for Toplink. Now I am just wondering if Emulated data source is good enough or should I go for Non-emulated data source for this situation.Can some one guide me on this. We have some connection pooling issues like connections reached max and Time Out exception..etc
Giri.

More to add to the above issue:
I have a method which executes some JDBC and toplink calls in a loop . Toplink calls are releasing connections to the pools but JDBC call are not releasing connections to the pool.Both connections use the same data source.

Emulated Data source

We recently upgraded from 3.x to 7.0. But we are not ready yet to convert our datasources to the new version, so we are running them as 3.x emulated datasources.
However in our test environment one of the data sources is the new version. This data source is 3.x in our dev & prd environments. I need to have this data source be an emulated 3.x version in our test environment too. Is there any way I can revert it back to a 3.x emulated data source?

AQJMS Exception - Nonemulated Data Sources

In the Application Server Containers for J2EE Services Guide 10g Release 2 (10.1.2) , Cap 4, DataSources, (pg 4-4) the doc shows two notes (plz see below) - one mentions an AQJMS Exception when you use a nonemulated data source and a non-Java-enabled database.
My Question no1: What type of exception is that (oracle.jms.AQjmsException ?) and what's the message (what does getMessage() return ? ) ?
My Question no2: reffers to the second note - for nonemulated ds the physical connections stay open even after a deploy of the app - doesn't this mean that after a set of deploy/undeploys we get the connection pool full of (the unclosed) connections from the very first moment ?
I have an environment with a set of mbds using the same datasource,oc4j 10.1.2.0, on solaris, using the OCI DRIVER, OJMS, with a max no of connections set to 90 and min to 30. I get a AQjmsException: Closed Connection at deploy time, but not constantly - only about 25% of the time.
Nonemulated Data Sources
Nonemulated data sources provide full (nonemulated) JTA services, including
two-phase commit capabilities for global transactions. [...]
Oracle recommends that you use nonemulated data sources for distributed database
communications, recovery, and reliability. Nonemulated data sources share physical
connections for logical connections to the same database for the same user.
Note: You must use a Java-enabled database to run a nonemulated
data source. When you use a nonemulated data source and a
non-Java-enabled database, deploying any MDB application (AQJMS)
generates an exception, thrown to OC4J stdout. If you switch to an
emulated data source or a Java-enabled database, deployment
proceeds correctly.
Note: When an application using a nonemulated data source is
undeployed, the physical database connection is not removed from
OC4J until OC4J is restarted.
Any help much appreciated.

Unable to collect 3.x data source replica in a request

Hi,
When i tried to collect a data source replica(3.x data source) in a request it is throwing an error.
But when i tried to collect a data source replica which is migrated to 7.0 it is aloowing me to do.
Please suggest me a solution.I want some datasources as 3.x only.

Hello,
Goto Transaction RSDS and delete the replicated BI7.0 datasource and choose BW3.x datasource while replicating.
Restoring 3.x DataSources
1. In the maintenance screen of the DataSource (transaction RSDS) in the original system (development system), choose DataSource ® Restore 3.x DataSource.
2. Enter a transport request.
3.If required, delete the dependent transformation (R3TR TRFN) and data transfer process (R3TR DTPA) objects.
4.Transport the restored 3.x DataSource (R3TR ISFS), along with its dependent objects, into the target system.
Emulation, Migration, and Restoring DataSources
Thanks

Regarding BI7 Data sources

Hi
I have replicated the data sources in BI7 for SD and fincial after activating them in R/3.
Now i am getting only Emulated version of data sources. Means 3.X version of data sources , all have square mark on data source name.
Please let me know how i will get BI7 data sources, Or does Data sources exist in bi7 version or not if they exist in bi7 version they why i am not getting them.
Thanks & regards
Micky

Hi Micky
3.x DataSource
In the past, DataSources have been known in the BI system under the object type R3TR ISFS; in the case of SAP source systems, they are DataSource replicates. The transfer of data from this type of DataSource (referred to as 3.x DataSources ) is only possible if the 3.x DataSource is assigned to a 3.x InfoSource and the fields of the 3.x DataSource are assigned to 3.x InfoSource InfoObjects in transfer structure maintenance. A PSA table is generated when the 3.x transfer rules are activated, thus activating the 3.x transfer structure. Data can be loaded into this PSA table.
If your dataflow is modeled using objects that are based on the old concept (3.x InfoSources, 3.x transfer rules, 3.x update rules) and the process design is built on these objects, you can continue to work with 3.x DataSources when transferring data into BI from a source system.
DataSource in 7.0
As of SAP NetWeaver 7.0, a new object concept is available for DataSources. It is used in conjunction with the changed objects concepts in data flow and process design (transformation, InfoPackage for loading to the PSA, data transfer process for data distribution within BI). The object type for a DataSource in the new concept - called DataSource in the following - is R3TR RSDS.
When you activate the DataSource, the system generates a PSA table in the entry layer of BI. You can then load data into the PSA. You use an InfoPackage to specify the selection parameters for loading data into the PSA. In the transformation, you determine how the fields of the are assigned to the BI InfoObjects. Data transfer processes facilitate the further distribution of data from the PSA to other targets. The rules that you set in the transformation are applied here.
There fore got to transaction code RSDS or right click on the 3x data source and then go with MIGRATE
Main menu Datasource -> "Migrate 3.x datasource -> datasource" select with export datasource.
After do soo , always go with export so that the meta data will match the existing 3x data source to the new 7 x data source
Hope this helps you

Data source for application using both pooled and non pooled connections

Hi guys.
I am integrating Oracle's connection pooling into an existing application that had formerly used dbConnectionBroker. It looks like this task should be quite straightforward. However, for consistency, I would also like to replace other Connection logic within the application to use Oracle classes. This will involve using OracleDataSource to obtain a Connection object. ( without pooling ).
So in this case, the application will use both pooled and non pooled Oracle connections. They will be connecting to the same database. The question I have is in regard to the use of data-sources.xml.
Are there any special considerations for the required attribute values within data-sources.xml under this scenario ?
Help will be greatly appreciated.
Regards.
Steve.

Hi Steve -
It should be feasible for you to define a single datasource using multiple location entries to indicate what sort of pooling behaviour you wish to use.
If you lookup and use the "location" attribute, you will receive a javax.sql.DataSource object which will not provide connection pooling.
If you lookup and use the "ejb-location" attribute you will receive a DataSource object that will support connection pooling operations.
Note that this is using the emulated datasource approach, and transaction support is limited to a single resource (one database) for these datasources - you won't get 2PC support for transactions.
If you need a transaction to span two separate resources (ie two databases in same tx) then you will need to use the non-emulated datasource approach.
There is a chapter in the J2EE Services Guide which describes the datasource model we have with OC4J. This might provide you with some more useful information. See Chapter 11 - http://otn.oracle.com/docs/products/ias/doc_library/903doc_otn/generic.903/a97690/ds3.htm#1004903

Error in Creation of BW data source

Hi All,
While creating a data source, i am selecting the Origin type Business ware house cube & in the RFC destination field i can able to select the BW syste. The problem is when i go to the next filed BW report and try to get the relevant BW report from F4 the system shows a log error as "System error in System" Message no. CRM_MKTTG_DS_MISC033.
In second case
I have taken an existing BW Data source and tried to recreate it manually filling all the fields with existing data source, RFC destination, BW report, Business partner and Function module.
In this case the system doesnu2019t throws any error, it is working fine if I create manually.
I am in a dilema why the system behaving like this. could you please throw some light on this issue.
Thanks in advance,

Unable to capture the Data Source into a Transport Request

Hi All,
We have a product hierarchy and we are using the data source :4R_PRODH_D_LGEN_HIER for the hierarchy.
Now we need to transport this structure to the quality environment but we were not able to capture the datasource:4R_PRODH_D_LGEN_HIER into a transport request.
When ever we activate the data source:4R_PRODH_D_LGEN_HIER it is asking for the Package and the Transport Request Number.If we give these details and save it, data source is not getting captured in the request, only the "bject Directory Entry" is getting captured.
Can someone please guide me on how to capture the datasource under "Data Sources in BW" in a transport request.
Regards,
Sachin Dehey.

Hi Sachin,
Hierarachy datasource is not captured as Attributes and Text Datasource. So what ever you have done is correct.
What ever is captured in Object Directory Entry is correct. So go ahead with your transports, once transport is done check the Hierarchy Infopackage with Available OLTP hierarchies and load the data.
Most important thing first see that the all Master & Transactional Datasources are transported in R/3 Dev to QA to PRD
In BW, datasources are not transported, only their replica is transported.
Transportation of Datasource is done in R/3. Only their replica is transported in BW.
So wht ever you have done till now is correct. So go ahead.
While attaching Hierarchy Datasource it is captured only in "Object Directory Entry"
Regards,
Vishnu.

Using a SQL data source and XML data source in the same template

I am trying to develop a template for the Request for Quote report generated in Apps 11.5.10. I have loaded the data from the XML output into the template, but I am missing one field - I need the org_id from the po_headers table. Is it possible to use a sql data source (i.e., "select org_id from po_headers_all where po_header_id = [insert header_id from xml data]...") in addition to the xml data source to populate the template at runtime? When you use the Insert > SQL functionality is it static at the time the template is created, or does it call to the database at runtime? I've looked through all the docs I could find, but this isn't clear.
Thanks for any help or suggestions you may have.
Rhonda

Hi Pablo
Thats a tough one ... if you go custom with a data template you will at least get support on the data template functionality ie you have a problem when you try and build one. You will not get support on the query inside the data template as you might have gotten with the Oracle Report, well you could at least log a bug against development for a bad query.
Eventually that Oracle Report will be converted by development anyway, theres an R12 project going on right now to switch the shipped OReports to data templates. AT this point you'll be fully supported again but:
1. You have to have R12 and
2. You'll need to wait for the patch
On reflection, if you are confident enough in the query then Oracle will support you on its implementation within a data template. Going forward you may be able to swap out your DT and out in the Oracle one without too much effort.

"Open sql" report no data sourced defined in windows

when I want to import data from sql database, the Open sql window report error
"There are no data sourced defined. Please create one to continue",
but I have defined the odbc data source using windows 's odbc administrator, why the error?
chuliang

A couple of possibilities.
First are you licensed for Sql interface? If not, you might get that message.
Second, where did you create the ODBC connection on your computer or the server. It has to be on the server.
Third, did you create the odbc as a system driver? it needs to be so
Fourth, what operating system? If it's unix or AIX there is a hole bunch more you need to do to get odbc connections working. If it's windows, it's pretty easy.
Fifth, did you test the connection before trying it in Essbase?

Excel-2007 cannot connect to Oracle ODBC data source, Control Panel can.


I cannot make an ODBC connection from Exce-2007 to Oracle work. I am an expert Excel and VBA user (since 1994) and I have frequently used Excel to access ODBC databases, including Oracle (I have done this with Excel-2003 both with worksheet queries and have written VBA ADO-connection routines). And even though in Excel-2007 a worksheet ODBC query is supposed to be easier to create than in previous version of Excel, my connection fails. Any suggestions and all help are welcome and much appreciated.
DETAILS


1) What is my system? I am using Excel-2007 on Windows Vista x64 and Oracle server v.11g on my computer (all this is on my computer, no network issues).
2) Why use Excel with Oracle at all? I use Excel-2007 to access Oracle rather than Access-2007 (or any other application like TOAD, etc.) because I do engineering calculations with the data stored in Oracle. These calculations are easier done in Excel (I suppose that one alternative to this could be to use some sql or Access to get the data from the database, then store it as plain vanilla CSV file, then open this file in Excel, then do the math (the math involves complex optimisation algorithms), then save the results as CSV, then use some sql or Access to put the data back into the database. Howwever this does not strike me as a quick or neat solution. And after all Excel has been designed to access ODBC databases, so why not use it?)
3) What do I do in Excel-2007 that won't work? I create an ODBC link to Oracle that does not work. In Excel-2007 this is straightforward:

<ul>
<li>define an ODBC connection (Data tab --> From other sources --> From data connection wizard);</li>
<li>define a query on the worksheet -- that's it, this is all!</li>
</ul>

I start with creating an ODBC connection:
a) I choose an ODBC data source type: ODBC DSN
b) Excel-2007 displays the list of the available ODBC data sources. I see in it my Oracle database name and I select it.
c) Excel-2007 displays the Data Link Properties:
- the "Provider" has a list of the OLE DB drivers with preselected "Microsoft OLE DB Provider for ODBC Drivers". I keep this default selection.
- the "Connection" tab has a connection string "DSN=<my database name>" which I keep, it also has fields for the user name and the password, which I fill with the correct credentials.
- Finally there is a button "Test Connection", which when I click produces the following error message:
"Test connection failed because of an error in initializing provider. 
Unespecified error"

4) Additional food for thought:
a) In the above walk-through the only data, which I type, are the user name and password, everything else is selected from lists offered by Excel-2007, hence any possibility of typos being the cause of the problem can safely be discarded.
b) I can test the ODBC driver in the Control Panel and it shows that it can connect to the Oracle database:
- in Control Panel --> Admin Tools --> Data Sources (ODBC) on the "User DSN" tab I can see the list of the available ODBC data sources (same list as in Excel-2007, point 3b above) with the name of my database in it;
- selecting the name of my database from the list of the sources and clicking "Configure" button opens a tab with Data Source Name (same as in Excel-2007), TNS Service Name and User ID. I enter <user name>/<password> and click "Test Connection" button. A message "Connection successful" appears (just for a test I enter incorrect user credentials and "Unable to connect" message appears)
BOTTOM LINE


The procedure for using an ODBC connection from Excel is very simple, in the past I have created and used such connections numerous times with Excel-2003 and earlier on Win-XP and earlier. But now on Excel-2007 and Vista-x64 I cannot make it work.
Also, testing an ODBC connection driver is really easy and simple to be done in the Control Panel. There testing the same ODBC connection, which fails in Excel-2007, results in success.
I am frustrated by the simplicity of the problem and yet the persistant error. I have lost now two full days in failed attempts to make the simple procedure work and in searching the internet for answers.
All help is highly appreciated <img class="emoticon" src="images/emoticons/happy.gif" border="0" alt="" width="16" height="16" />,
Plamen


Did you find the solution to your problem?
If not, I think I may know.
Excel 2007 is a 32-bit application.
When installing 32-bit applications in a 64-bit environment, the "default" location is:
C:\Program files (x86)\...
Excel then launches from this location.
However, when it connects to Oracle and passes the name of the calling program, Oracle attempts to "interpret" the value of (x86) as if
the value within the parenthesis are being passed as a reference. Of course, iOracle doesn't find anything, so the result is (),
and then it cannot return the connection info back to the calling application.
I corrected it by installing Excel in C:\Program Files\, and once launched from that location, it works the same as on the 32-bit machines.
However, at my location, they are FORCING Excel to be installed in the(x86) location.
What I'm trying to discover now is:
Is it possible to flag Oracle to NOT process the embedded variables?
Or, is it possible to assign a variable in Oracle such that x86 = "(x86)", so that the end result is viable?
Have you had any luck with your installation?
thanks,
Paul

Refreshing the Data Source View in Analysis Services

I have added columns to the SQL Database table that is used as a dimension in an Analysis Services Cube. The new columns will be used as additional Property Fields for the dimension. When I attempted to refresh the Data Source view so that the additional columns are present, I am given the following error:
System.Data
Property not accessible because 'Parent Columns and Child Columns don't have type-matching columns'
I have done nothing to the columns used for the parent of child and the error message provides nothing to gon on. Does anyone have any ideas on this?
Gary

Olga,
Thanks for your response. I will try and answer your questions
1) I have not tried removing the columns yet. I will try that this afternoon but have limited hope. The two columns I added are simple text columns that will be used as attributes in the dimension. I have made no change to the parent or child columns.
2) The table I modified is the source table for a parent-child dimension.
3) The reference to the "check list" does not take me to any kind of check list.
4) The parent-child dimensions I am trying to modify have been in use for months and the parent and child columns do have the dame data types.
5) I have also check the data types between the dimension table and the fact table. they use the same data types (small int).
6) I have not made a collection for the parent key, it is a single column. The remainder of your last paragraph is not clear to me. Can you give me an example.
I am fairly inexperienced with Analysis Services, please talk slow and use small words :-)
Thanks again for your help!
Gary

Then I decided to use eis/DB/SOADemo for testing.
For JDeveloper project, after I deployed to weblogic server, it works fine.
But for OSB project referencing wsdl, jca and mapping file from JDeveloper project, still got the same error as follows:
BEA-380001: Invoke JCA outbound service failed with application error, exception:

You may need to configure the connection settings in the deployment descriptor (i.e. DbAdapter.rar#META-INF/weblogic-ra.xml) and restart the server. This exception is considered not retriable, likely due to a modelling mistake.
It almost drive me crazy!!:-(
What's the purpose of 'weblogic-ra.xml' under the folder of 'C:\Oracle\Middleware\home_11gR1\Oracle_OSB1\lib\external\adapters\META-INF'?
