Report model to have multiple data sources

Hi,
We have requirement to develop report model in 2008 having multiple data sources which includes SQL SERVER 2012 and Oracle database so end user can all the relevant data in one place to run in report builder. So please advise how this can be achieved.
One option I can think of pulling all the data into one database through SSIS and then build a smdl on it.
I heard it might be possible to build Tabular cube and then use Report builder on it not sure which is the best option unless any other solution.
Thanks,

There are multiple options
1. If its just for need of a single report then you don't necessarily need to use SSIS and bring all data to single database for that. SSRS supports multiple heterogeneous datasources so you can simply create multiple datasources one fro SQLServer and one
for Oracle. Then you can create datasets based on these datasources and use them inside reports to display the data from the two systems.
One thing to note here is that SSRS provides only limited capability to merge fields from multiple datasets within same container through the use of Lookup, LookupSet etc functions so if you want to do lots of comparison ,manipulation of fields against two
datasources then you need to go for common database approach itself. This involves building a datawarehouse/datamart which will assmeble data from various sources and change them into format which report expects. Then its just a matter of using single
datasource pointing to this common repository for your reports.

Possible to have multiple data sources within 1 SQL querey?

Hi All,
Is it possible to join to a table in a different datasource within 1 SQL Querey?
Something like...
Connection 1
Select *
From Table
Join
Connection 2
On
Connection1.Table1.Field1 = Connection2.Table2.Field2 Thanks,
John

Is it possible to join to a table in a different datasource within 1 SQL Querey?Called distributed joins - joining a table from one database with that of another database. Also possible to do heterogeneously across different database products - e.g. joining an Oracle table with a SQL-Server table.
As already explained, some kind of communication interface is needed from the local database to the remote database, in order for the remote table to be read and joined to the local database. This interface is called a database link in Oracle.
The basic steps. First define the database link:
create database link <linkname>
connect to <account>
identified by <password>
using <connection-string>Complete syntax details and examples are in the SQL Reference Guide (see http://tahiti.oracle.com)
After the database link has been identified, you should now be able to address remote tables as follows:
select * from <remote-table>@<link-name>A distributed join would look something like the following:
select
from <local-table> t1,
<remote-table>@<link-name> t2
where t1.. = t2..However... this is almost always a BAD IDEA to do distributed joins. It seldom performs well. Performance is immediately constrained to the speed, bandwidth and latency of the network link between local and remote databases. It cannot scale with data volumes and increased frequency of use.
So if the remote table is not small, the network link not robust and reliable, and join not infrequent, it is bad idea to make use of distributed joins. In which case other alternative (and far superior) features need to be considered instead - like materialised views.

Increase performance in a multiple data source report

Post Author: ArturoFromPeru
CA Forum: General
Hi everybody.
I have a big problem, when i make a report that have multiple data sources the performance decrease considerably, i still don't know the reason. Is it true that using multiple data sources is too slow?.
I tell you a fact: I made the report connecting via "Field Definition File", and it take at least 2 minutes to show itself but it only have 170 records, and i'm very sure that the sql statements to each data source were executed very faster.
I even heard about index, but i think they only are useful when i connect directly to the database.
All my partner told me, that Cristal Report
Thanks you in advance
Regards.

Thanks you, but I explain better what i was doing.
I've made a report called "Kardex de Producto" which show the behavior of the products according to its sales, purchases.
The end result which is showed by the report is correct. I used three data source in the report, so links between each table is correct. The only problem i have is the performance because i still don't know why is too slow. In fact the sql statement is very heavy, but i think it doesn't matter to the report because when it takes the data from the database (connecting via Field Definition File) even if the very heavy sql statement returns twenty record Cristal Report must show itself very quickly. I don't want to believe that Cristal Report is very slow when it works with multiple data sources.
Do you mind if i give you my report? if not please leave me your email address.

Multiple data sources in endeca

Hi,
I have multiple data sources in endeca like web crawler, xml,database, txt or pdf etc.
Can all be configured through dev studio or all through cas or some from cas and some from dev studio?
Pls let me know..Thanks!

You will most probable need both CAS as well as dev studio. Web crawls and ingesting docs will have to be configured through CAS. Database and txt files (if they are delimited) can be ingested through pipeline.
You can send the data from CAS (record stored) directly to forge as input OR you can send it to the pipeline if you need further modifications to it.

CFTransaction & Multiple data sources

We have the need to update to multiple data sources under
CFTransaction. We have two MSSQL databases so I was able to create
a view in one to the other and that works (unless someone knows of
a problem that could cause). But we also have a MSAccess db that
gets hit too under the same CFTransaction. CF does not allow you to
have multiple data sources under one CFTransaction. If all the
tranasction control is on the db side, why does CF care if there
are different data sources?
Thanks.

As I said in my original post, in order for a transaction to
span multiple databases, you need to do what's called "2-phase
commit" or "distributed transactions". This is not a trivial thing
to do, nor is it something that is often needed (especially in
Coldfusion, which is 99% of the time talking to a single database).
Why do you need to do 2-phase commit? and why isn't it
trivial?
"2PC is an acronym for 2 Phase Commit. This is a protocol by
which data being committed to a database is committed in two
phases. In the first phase, the transaction processor checks that
all parts of the transaction can be committed. In the second phase,
all parts of the transaction are committed. If any part of the
transaction indicates in the first phase that it cannot be
committed, the second phase does not occur. ODBC does not support
two-phase commits."
http://docs.openlinksw.com/virtuoso/twopcimplementation.html
I don't think Access supports 2-phase commit. Access isn't
really intended for the kinds of things that need 2-phase commit,
which Microsoft readily admits (hence MS SQL Server).
> My thought is that it is not allowed because CF only
remembers one data source per cftransaction therefore can only send
one commit or rollback instruction. If that's the case, it sounds
like a simple enhancement.
No, this isn't allowed because distributed transactions is a
non-trivial thing. This isn't all handled on the database side, as
you reference. If you're dealing with one datasource, yes, it does.
Once you pull in a 2nd datasource, you need something that can talk
to all databases involved (a transaction coordinator) and 1) check
to make sure everything can be committed safely then 2) commit
everything (hence 2-phase commit).
Basically, you're trying to do something that's non-trivial,
you don't understand why it's non-trivial, so you're getting
frustrated. I realize you're not a Java shop. I was simply trying
to explain to you why it was non-trivial, and a method to work
around that if you so desire.

Report Viewer and Multiple Data Sources

I know that it is possible to create a report in Crystal Reports using multiple data sources. But is it possible to use just the Free Report Viewer to view a report with Multiple Data Sources?
Our company uses Crystal Reports XI. I do not use the program myself, I am in the IT Department. I have limited knowledge of Crystal and do not do any of the report writing.
If this is possible, and if someone could help me out with what would need to be done, or point me in the right direction of a Knowledge Base or Help Topic that explains this, that would be great.
Thanks.

I believe it can but both data sources need to be set up. Ask a report designer to help you use the Designer to test this and see what is required.

BI+ Reporting With Multiple Data Sources

Hi -
We've been using BI+ Reports with multiple data sources on separate grids. We are wondering if there is a better way to ensure the user has their point of view bar in sync between the the data sources. In our case, both Data Sources are separate HFM applications with all the dimensions identical except the account which is defined on the report. We are not using Metadata Management.
I'm aware of the "Merge Equivalent Prompts" in the Preferences > Financial Reporting window, but this does not always ensure the users have the same point of view.
What practice are other companies using to make sure the user runs the reports accurately with both point of view bars pulling the same entity/year/period.
Thanks in advance.

Thanks for your answer, however my question - I know it looks quite messy - is not directly related to data templates, my problem is that at the moment I am using a stored procedure following - almost exactly - what another procedure does in oracle EBS to call a BI publisher report.
1. This procedure populates some temporary table with the xml data where the concurrent request picks it up and uses it to populate the BI publisher template.
2. However I can't go and specify the XML location in my data template as this is not an option for us (i.e. reading the xml from the temporary table), so I am looking for another way to populate the BI publisher template (Note: I can't as well include the SQL queries in my Data template).
Thanks ;)

Can we combine multiple data sources in single report?

<span style="font-size: 10pt; font-family: Verdana">Can we combine multiple data sources in single report?</span>

If you can't do this at the Metalayer (BVs or Universe) - then subreports and shared variables are the method for CR to use multiple datasources in the same report.

Multiple Data Sources In One Logical Table

I am new to OBIEE and I have came accross an issue. I appologize if this information is in the forum somewhere but I have searched and cannot find it.
My situation is that I would like to have one logical table that contains multiple data sources which have all the same columns. I already have session variables setup to differentiate the user's security through a row-wise variable for a specific column and a session variable for another column which determines the user's association to the data source in which they belong to. This security works well when the data sources are seperated in the Business Model and Mapping portion but the issue that arises is that the user's cannot share reports when the data sources are seperated in the BM&M.
I have dragged and dropped a table from the Physical model to the BM&M, I then dragged the second data source (with same meta data structure) over to the "Sources" folder in the first data source table in the BM&M. On the Content tab or each data source table I have defined the WHERE clause as such, where VALUEOF(NQ_SESSION."SCHOOL") session variable is my row-wise column filter and the VALUEOF(NQ_SESSION."GROUP") filter is my data source determinative:
sandbox."".SANDBOX.OBIEE_CROSS_ENROLLMENTS.HOME_SCHOOL = VALUEOF(NQ_SESSION."SCHOOL") AND sandbox."".SANDBOX.OBIEE_CROSS_ENROLLMENTS.DATA_SOURCE = VALUEOF(NQ_SESSION."GROUP")
Unfortunatley this only returns values in the BI Answers for the first drag and drop Pysical table in the BM&M layer and not the second Physical table drug into the "Sources" folder. I have also tried to create a new logical table and drag both tables into the "Sources" folder to no avail. I have experimented with the Fragmentation content on the "Content" tab of the seperate logical tables, checking the "This source should be combined with other sources at this level", which gives me an error in BI Answers that a column does not exist which really does.
What could I be missing? Advanced thanks to those who reply.
Thank you,
Kyle

Stijn,
Thank you for the article link. That was very helpful! It seems that I had a few things off as you do need the "This source should be combined with other sources at this level." checked. In my two table source columns for DATA_SOURCE I defined a literal ('086496' and '085597' for the other) in the Column Mapping tab. I pasted the following in the Fragmentation content, checking the "This source..." box on the Content tab:
eSIS.SANDBOX4_SCHOOLS.DATA_SOURCE = '086496'
And pasted the following into the WHERE clause, checking "Select distinct values" on the Content tab:
sandbox4."".OBIEE.NWOCA_SCHOOLS.SCHOOL_CODE = VALUEOF(NQ_SESSION."SCHOOL") AND sandbox4."".OBIEE.NWOCA_SCHOOLS.DATA_SOURCE = VALUEOF(NQ_SESSION."GROUP")
This took care of my user's security, utilizing the session variables in the WHERE clause. I am now able to generate reports that only one user can access from one data source and share that same report with another user who can only see data from the other data source.
Many thanks!!!

Any examples of a data template using multiple data sources?

I'm looking for an example report using multiple data sources. I've seen one where they do a master/detail but I'm just looking to combine results in sorted order (sorted across all data sources). The master/detail used a bind variable to link the two defined queries, I'm thinking what I want won't have that, so I'm lost on how to make that happen. I have reports using multiple sql queries and there is a way in the data source pulldown to tell it to combine the data sources. It appears to be a more manual process with data templates, if it's even possible.
Any pointers/links would be appreciated.
Gaff

Hi Vetsrini :
That's just it. Mine is simpler than that. There is no master/detail relationship between the two queries. I have the same exact query that I run in two databases and I want to merge the results (ordered, by, say eventTime) in one report. So I think my results are going to be two separate groups (one for each data source) which I'll have to let BI merge vis XSLT or whatever it uses. That's fine for small result sets but for larger ones, it would be nice if the database did the sorting/merging.

Bursting with multiple data sources

Hello all,
I am working in a retail environment and we are building reports for the stores. There are several reports and they all receive the same reports. We are using BIP Entreprise with the bursting feature and it works very well.
The problem is that there are too many reports and we would like to combine all reports of the same store within the same PDF. We use the multiple data source feature and was able to concatenate all reports together.
Using this new report and template, we can not make the bursting functionality to work properly: the bursted report do not contain all the required report components.
For example, I have 2 queries A and B each producing reports for 3 stores: 2, 4 and 5. Without bursting, the output is as is:
Query A - Store 2
Query A - Store 4
Query A - Store 5
Query B - Store 2
Query B - Store 4
Query B - Store 5
With bursting into a file using the store number, I get the following:
File 1 - Store 2 - Query A
File 2 - Store 4 - Query A
File 3 - Store 5 - Query A
+ Store 2 - Query B
+ Store 4 - Query B
+ Store 5 - Query B
I would like to have the following output:
File 1 - Store 2 - Query A
+ Store 2 - Query B
File 2 - Store 4 - Query A
+ Store 4 - Query B
File 3 - Store 5 - Query A
+ Store 5 - Query B
The main question is: can this be done using BI Pub Enterprise? We using version 10.1.3.3.2
If it is, can you provide me with help on how to configure either/or the requests and template to accomplish this task?
I create an SR and Oracle Support does not have an answser and suggested that somebody in the Forum might help.
Thanks in advance,
Minh

I would like to have the following output:
File 1 - Store 2 - Query A + Store 2 - Query B
File 2 - Store 4 - Query A + Store 4 - Query B
File 3 - Store 5 - Query A + Store 5 - Query B
the bursting level should be give at
File 1 - Store 2 - Query A + Store 2 - Query B
so the tag in the xml has to be split by common to these three rows.
since the data is coming from the diff query, and the data is not going to be under single tag.
you cannot burst it using concatenated data source.
But you can do it, using the datatemplate, and link the query and get the data for each file under a single query,
select distinct store_name from all-stores
select * from query1 where store name = :store_name === 1st query
select * from query2 where store name = :store_name === 2nd query
define the datastructure the way you wanted,
the xml will contain something like this
<stores>
<store> </store> - for store 2
<store> </store> - for store 3
<store> </store> - for store 4
<store> </store> - for store 5
<stores>
now you can burst it at store level.

Adhoc Query Requirement with Multiple Data Source

Hi All,
I have a Adhoc Query Requirement with Multiple Data Source. Is there any way to achive it. Other than Resultant set and bring into Model.
Thanks
SS

You can compare stuff in the EL, but I don't think this is what you need.
You can just use Java code in the backing bean class for all the business logic. You can use DAO classes for database access logic. Finally for displaying you can use the JSF tags such as h:outputText.

Data Extraction from Multiple data sources into a single Infoprovider

Hi Experts,
Can anyone send me links or examples on how to extract data from multiple data sources into 1 Cube/DSO.
Can anyone send me example scenarios for extracting data from 2 data sources into a single Cube/DSO.
Thanks
Kumar

Hi Ashok,
Check the following link from SAP help. Ths is probably what you are looking for.
[ Multiple data sources into single infoprovider|http://help.sap.com/saphelp_nw70/helpdata/en/e3/e60138fede083de10000009b38f8cf/frameset.htm]
Data from multiple data sources which are logically related and technicall have the same key can be combined into single record.
For example, if you have Sales order item and sales order item status .
These both have the same key - sales order and item and are logically related.
The Sales order item - provides information on Sales order item - material , price, quantity, plant etc.
The item status - povides information on delivery status, billing status, rejection status....
These are two different data sources 2LIS_!1_VAITM ad 2LIS_11_VASTI.
In case you have few master data attributes coming from different systems ie tow data sources in different systems say completely defines your master data. Then you could use a DSO or infoobject to combine the records.
If you want to see aggregated data you use a cube.
ie say you want to analyzae the customer revenue on a particular material and a particular project.
The project details would come from Project syatem and Sales details fom sales flow.
The data is then combined in the DSO with key cutomer and sales area say.
Then it is aggregated at cube level...by not using sales order in the cube model...so all sales order of the same customer would add while loading the cube.. to give direct customer spend values for your sales area at aggregated level.
Hope this helps,
Best regards,
Sunmit.

Does OBIEE has ability to create a single cube from multiple data sources?

Hi all,
Does OBIEE has the ability to create a single cube from multiple sources and does it has the ability to join multiple cubes?
Looking forward to ur reply.

Hi
OBIEE can join multiple data sources to make a single data model, but it's not a cube in the multi-dimensional sense like Essbase or Oracle OLAP.
To be able to join datasources together they need to have a common dimension or FK relationship depending on what the source is and what you want to do with it.

Report using excel sheet as data source not working when deployed to production.

I have a set of SSRS reports that use an excel sheet as a datasource.
Now when I preview the reports or run them in the Visual Studio IDE on my local machine i.e
the development machine, the reports run fine & display all correct results.
However, when we deploy the reports to the Production machine which is on a separate server,
the following error message is displayed :
"The current action cannot be completed. The user data source credentials do not meet the requirements to run this report. Either the user data source credentials are not stored in the report server database, or the user data source is configured not to
require credentials but the unattended execution account is not specified. (rsInvalidDataSourceCredentialSetting)"
I've copy pasted the connection string used for connecting to the excel file as reference :
Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\MyFolder\CurrentFile.xlsx;Extended Properties="Excel 12.0;HDR=Yes;";
The excel file has also been uploaded to the machine housing the reporting server (i.e to C:\MyFolder location)

Hi Aaakar,
From the error message, please try to change the setting of Credential type for the data source on report manager as follows:
Go to the Data Sources properties page.
For the Connect Using option, select Credentials stored securely in the report server.
In User Name and Password, type credentials that can be used to access the database. If you are using SQL Server as the data source, the user name must be valid for both logging on to the server and for accessing the database that contains the data for
the report.
If the user name and password are credentials for a Windows account, select Use as Windows Credentials.
If you want the report server to pass the credentials of the user accessing the report to the server hosting the external data source, click Windows Integrated Security. In this case, the user is not prompted to type a user name or password.
For more details about Configure Data Source Properties, please see:
http://technet.microsoft.com/en-us/library/ms155882.aspx
Hope this helps.
