Dynamically switch phisical data source

Hi,
Is it possible to dynamically (during one session) change connection pool data source parameter in OBIEE 11g?
In my case there are 4 OLAP cubes with the same structure dedicated for different regions. I like to change data source standing behind report after user select region in dashboard prompt.

It's possible but there is important limitation in AWM when we speak about OLAP data sources. You can't duplicate dimension names within one database schema. Also, I didn't find a way to parametrize database schema. You can only dynamically switch database name so need separate database per OLAP cube.
1) Define separate database definitions in TNSNAMES.ORA file (in my case db name is country name).
2) In admin tool create variable and init block that will set default database name.
Manage -> Variables... -> Action -> New -> Session -> Variable
3) Use variable as data source:
Connection Pool -> Data source name -> VALUEOF(NQ_SESSION.COUNTRY_DATABASE_NAME)
4) In analytics use dashboard prompt with list of countries (same as database names defined in TNSNAMES.ORA). With prompt set request variable (COUNTRY_DATABASE_NAME)
Let me know if you found better way to achieve similar functionality.

Setup dynamic Web Service Data Source

Hi all,
is there a way to setup a "dynamic" web service data source like
WSDL-URL = 'http://${server_ip}:${server_port}/XYZService?wsdl
and passing in the server_ip and server_port variables from outside upon document rendering?
As far as we have seen, there is not way to do so - leaving us with a static web service data source configuration that is only able to point to one specific WSDL.
The use case we have here goes like this:
1) We have one specific template for a specific document to be rendered.
2) Depending on the caller, the data source must be different, i.e. the same web service at different endpoint addresses must be called to fetch the right data.
Any ideas?
Thanks in advance.
Best regards,
Stefan

Hi Klaus,
thanks for your reply. We also had that idea with the router web service ;-) But a little more flexibility would be great for us due to our decentralized system landscape.
Currently, we are in the evaluation phase of BI publisher to replace our local reports (sales documents) with BI Publisher reports having one central instance of BI Publisher and n local store instances all providing a getSalesDocument() web service.
To be able to call the correct web service, a dynamic config of web service endpoints would be helpful.
Best regards,
Stefan

XSL - dynamically select XML data source

I need to create an XSL file that will be used to transform
one of many XML
files. The XML files are structurally identical, but they
contain different
data. I would like pass a parameter (most likely in the query
string)
identifying the appropriate XML to an ASP page that includes
an XSL
transformation that would select the appropriate XML file as
its data
source. Can anyone point me in the right direction?

Perhaps you did not set to evaluate the variable as expression

Can we set the dynamic data source when using getReportParameters() ?

Hello!
I have a report where one of its parameters refers to a list of values (LOVs). This list of values is an SQL Query type. When the data source used in the report is defined in the BI Publisher server, I'm able to get the report parameters using the getReportParameters() function in my application. However, if the data source is not defined the function throws an exception, which is understandable.
I decided to dynamically set the data source so that even if the data source used by the report is not defined in the BI Publisher server, it still will be able to get the LOVs for the parameter. I tried setting the JDBCDataSource of the dynamicDataSource for the ReportRequest object that I passed to the getReportParameters() function. Please see the sample code below:
reportRequest.dynamicDataSource = new BIP10.BIPDataSource();
reportRequest.dynamicDataSource.JDBCDataSource = new BIP10.JDBCDataSource();
setReportDataSource(reportRequest.dynamicDataSource.JDBCDataSource, connectstr, jdbc, dc); //function to set the values for JDBCDataSource object
reportParams = webrs.getReportParameters(reportRequest, uid, pwd); //call the getReportParameters
I was expecting this to work as this is what I did to dynamically set the data source before calling the runReport function. So, my question is -- can we set the dynamic data source when using getReportParameters() ? I tried this both in versions 10g and 11g. It does not seem to work on both versions.

Stephanie

report_id column of apex_application_page_ir_rpt can help us uniquely identify each saved report.
We can assign this report_id value to a page item and this page item can be put in the Report ID Item text box of the Advanced section of the Report Attributes page of the IR.
This should load the saved report identified by report_id and you can get rid of javascript

Switching Data Source for a report with stored procedure

Post Author: ysbn
CA Forum: Data Connectivity and SQL
I've created a report and deployed it on a Crystal Server. The report is based on a certain stored procedure which also exists on other DB machines in my environment (Oracle machines). When I try to switch my report object to work with other machines (not the one originally used when the report was designed) the activation of the report fails. The error I see in the preview window is:
Error in File <my rpt file name>: Failed to retrieve data from the database. Details: [Database Vendor Code: 6550 ]
When I try the same thing with a report which is based on a view and not a stored procedure the switching of Data Source works perfectly.
Is there a problem switching between data sources from the server when the report is based on stored procedure? Are there any configurations I need to do in order to support this scenario?
Thanks!

Hi everyone~
i am now facing the same problem
i am using CR2008 and Visual Studio 2008 c# to write a window program
because we have 2 db environment (one is production , the other one is development) so i have set a prarameter to switch db connection in c# code.
the database is Oracle, and the the report will connect to Oracle procedure (which it is stored in package) this procedure will return reference cursor, so the report will loop up this cursor to generate report.
at first time, it work fine when i open the report in CR2008 designer and point to dev database (ie datasource point to oracle procedure) . but when i want to deploy this win application to client and point to prod database, it show (vendor error 6550)
i found that i cannot change the datasource during runtime in c# code...
am i miss something in code? here attached a part of this code...
private void setDBLogonForReport(ConnectionInfo info, ReportDocument doc)
            Tables myTables = doc.Database.Tables;
            foreach (Table myTable in myTables)
                TableLogOnInfo logOnInfo = myTable.LogOnInfo;
                logOnInfo.ConnectionInfo = info;
                logOnInfo.TableName = myTable.Name;
                myTable.ApplyLogOnInfo(logOnInfo);
                //myTable.Location = info.UserID + "." + "pkg_crystal_report." + myTable.Name;
                //someone suggest i have to set the 'Location' for change the datasource, but i am not sure how to construct a
                //string for point to oracle prcedure
i will check it freq ... hope any expert can give me some advice ~
thank you very much!!!

Dynamically modify data sources

We have a need to dynamically modify our data sources and I need to know if this is possible and what the syntax is? Can we do this as a transaction and/or in the javascript / jquery logic of the UI? I know that basically everything is configurable as a transaction or as a script. I need a little assistance in configuring the below items for a data source.
DaysRetention
Description
IP
MaxRetryCount
Port
QueryTimeout
RetryInterval
ServerPackage
Writable

Data server configuration properties are easily modifed from the editor page in the Menu, and is typically an initial or configuration setting made before building application content (query templates).
At runtime overloading the Server property within or in addition to a query template is quite easy, but no standard provisions are in place for modifying the data server configuration itself.
Why would you have a need to modify them dynamically through code?

Change Data Source in SMSY from "manual" to "SLD"

Hello,
unfortunately some of my systems appear in SMSY with data source "manual" although the data is collected automatically via SLD. How can I switch the data source to "SLD" for these systems?
I already tried to delete the system in SMSY. After the next SLD-Sync-Run the system still has the setting "manual".
Can someone help?

I have the situation where I have a system in the SLD but cannot get the SLD to update it. The data source is Manual (Automatic Refresh). I've tried changing this to the other manual data source, running the landscape fetch, changing back to manual (automatic refresh) and running landscape fetch again. Still, the data source says Manual (Automatic Refresh). I even tried to delete everything about this system and add it back. I couldn't get the corresponding system component deleted but did manage to delete everything else. After re-creating, I still have the problem. I can't find the solution. Any ideas from anyone? Thanks!

Setting Crystal Report data source at runtime

In advance, I've read all of the posts on here about dynamically changing the data source for your report at runtime and none of it seems to work.
I developed a report against my development database using an MySQL ODBC connection. At runtime I want to pull the data from the production database. I've tried clearing the DataSourceConnections. I've tried the SetDatabaseLogon as well as Table.LogOnInfo, Table.ApplyLogOnInfo, SetConnection, everything.
I am using the pull method for getting the data, so CR has entire control over the mechanism used to fetch the data.
But when I am setting some other data source I am greeted with a logon screen for the database, I i check use itegrated security then it says logon failed and if I uncheck use integrated security checkbox then it shows unable to load report and an exception is thrown
Anyone have any ideas? I'm using Visual Studio 2010 and Crystal Reports 2011 developer edition.Apart from this my Database is in mysql and I am binding report with the MySQL Procedure.
Note: Both these database just differ in name, Infact they are same database just I have changed the name, so the procedure and the fields are same.
Thanks in advance.

So if ODBC doesn't allow me to change the data source, can't it be done in some other way without mingling with each and every report.
BDW I am able to change the data-source at designer mode,
Currently the connection string being used is
private readonly ConnectionInfo crConnectionInfo = new ConnectionInfo
            DatabaseName = "DB NAME",
            IntegratedSecurity = true,
            Password = "admin",
            ServerName = "localhost",
            UserID = "root"
I just want it to read from same copy of database place at some other location so the connection string will be modified as
private readonly ConnectionInfo crConnectionInfo = new ConnectionInfo
            DatabaseName = "Same copy of database record may change but structure will be same",
            IntegratedSecurity = true,
            Password = "admin",
            ServerName = "IP address of the machine",
            UserID = "root"

How to dynamically populate data from a data source

What I am trying to do:
I am building a simple blog reader application with two screens, 'Home' and 'FeedR'.
The data needed for this to work is an excel table 'Blogs'; which has the following columns:
BlogName, image, Source
I have created about 6 REST data sources from the RSS feeds of these blogs and added their names into the excel table.
The home has an "Image Gallery with Text", which has the blog image and BlogName on it. On the select event, I want to navigate to the second screen and populate the text gallery with the feed details.
The Problem:
So, when I have only feed, I can do something like:
'Navigate(FeedR, ScreenTransition!UnCover);Collect([@blogposts], rss_aspx!channel!item)'.
When I have more than one feed; I would like to be able to do something like:
'Navigate(FeedR, ScreenTransition!UnCover);Collect([@blogposts],
(Blogs!Source)!channel!item)'.
The Question:
Is dynamically populating the name of the data source work? If yes, how do I do it? If no, is there a way around it?
I was looking at UpdateContext(), but does not seem like a feasible option.
Thanking you...
Hemanth

you wanted a onchange for a htmlb:inputfield which would also trigger server event. try the following code.
<htmlb:inputField id            = "test"
                            alignment     = "LEFT"
                            size          = "6"
                            required      = "TRUE"
                            doValidate    = "TRUE"
                            type          = "INTEGER"
                             />
<bsp:htmlbEvent id="myid" onClick="myonclick" name="ValueChanged" />
<script for="test" event=onchange type="text/javascript">
alert(this.value);
ValueChanged();
</SCRIPT>
if the value in the inputfield is changed it would trigger a alert at the client side and also trigger a server event. now you can caputre the value in oninputprocessing.
Hope this helps.
do let us know if you need help in how to capture this value in oninputprocessing.

Dynamic File Name in Data Source?

In Data Model, there is a option "File" as Type. My question is can file name be dynamic, say I set a parameter "ReportID", can this parameter be part of file name. something like
{$ReportID}.xml
or
{:ReportID}.xml
If yes, what is the syntax.
Thanks.

I don't think you can do that. When you speficy 'File' as the type for the Data source, it expects an existing XML data file stored in the directory that has been set up by the Administrator.
There is no way to define a parameter for the file name and then use this instead..
Thanks!

Question on Dynamic Query Data Source and Form Folders in Oracle Forms 6i

Hi there -
I have one interesting requirement in Oracle Forms.
This is what I wanted to do.
1. Have a LOV and Go button on Form.
2. From LOV, I will select a pre-defined custom table and click Go.
3. Based on the selected custom table, I have to populate the Block (Tabular Format).
4. User should be able to do update, delete, insert on this block.
5. User should be able to use the Oracle Form folders functionality (select only necessary column and save views etc. Std folder functionality).
6. If user selects a different custom table name in the LOV on top, I need to refresh the data from the block based on this new table. Remaining functionality should be as it is (steps 3 to 5).
You can see here, I am going to have dynamic query data source (Table Name as well as column mapping) on the block. I do not know before hand how many columns the user selected table has!
This is what I have planned for this so far but I have some major questions before I can move on with this design:
1. I am going to create a table structure with fixed number of column in form (40 cols assuming that the custom table will not have more that 40 cols). (Kind of limitation but it's okay as of now).
2. Dynamically populate the block based on the table name selected by the user from LOV. Dynamically change the table column names based on the table selected etc.
3. Perform insert, update, delete using PL/SQL package.
So far it looks okay.
Now my real question is,
Can user still be able to user "Folders" functionality here? I have never done this kind of development before and I doubt the dynamic column naming, dynamic column data source will really work for "folders"!
Also, I am not really sure whether user will be able to save these "folder" queries?
Okay so form experts, can you ppl suggest me if this is really going to work? Are there any better ways to do this?
Initially I tried to do this in OA Framework but I got stuck at because as per OAF developer guide "I cannot user OAF personalization for dynamic items, regions etc".
For more info on that thread see this link...
Re: setUserCustomizable issue!
Thanks in advance for the help.

How to select column dynamically with sharepoint list as data source in ssrs report

<FieldRef Name="title2" />
</ViewFields>
</RSSharePointList>

Hi MNRSPDev,
Sorry for the delay.
According to the current description, I understand that you want to specify column name in dataset query designer dynamically when using SharePoint list data source.
Based on my research, this is not supported by default. As a workaround, you can use XML data source. The XML content can be embedded directly within the query. This lets you use the expression capabilities within the processing engine to build queries and
data dynamically within the report. And it can be used for retrieving XML data directly from an external data source, passing it using parameters, and embedding it within the query.

Hope this helps.

Dynamic data source in Excel Pivot Table

Hello there,
I am trying to have dynamic data source in pivot table using INDIRECT but getting the error "Reference not valid". Here is how I setup the reference:
Named range: ConsolLink = "'R:\Root\Sub1\Sub2\Consol File.xlsm'!Source_OpexConsol"
"Source_OpexConsol" is defined in the source file as a dynamic name using offset formula.
In the pivot data source, I have tried "=INDIRECT(ConsolLink)" as the data source but that does not work.
I have also tried using INDIRECT in ConsolLink and just referencing "ConsolLink" as the data source. That does not work either.
I am not using Power Pivot. Appreciate it if someone can help.
Thanks.

If it is open, then try
Named range: ConsolLink = Range("Consol File.xlsm'!Source_OpexConsol")
And if it is not currently open, then try
Dim W As Workbook
Set W = Workbooks.Open("R:\Root\Sub1\Sub2\Consol
File.xlsm")
Named range: ConsolLink =
Range("Consol File.xlsm'!Source_OpexConsol")
W.Close False

Using an Excel file as a dynamic data source? Opinions needed...

I have posted this topic before, but as always; in order to get the relevant correct answer you have to ask the correct question.
I'm trying to create a number of Pricelists linked to an Excel/CSV file. I have a Excel file that contains Pricelist information which is Product specific.
I have had a number of suggestion that follow:
A direct link to the Excel file. PROs: Excel file can be uploaded on FTP and overwritten if (and when) amended. Linking this is easy peasy in Dreamweaver. Person browsing can download info straight away on request - no hassle. CONs: Simply, not everyone has Excel and those who don't can not access the information.
Import Excel file as tabular data. PROs: Fairly easy to do in Dreamweaver. Person browsing can see info straight away. CONs: Can be time consuming on larger Excel files. NOT amendable (so a number of price changes becomes a big job). Can't simply overwrite Excel file on FTP. Larger Excel files can take a lot of page space and thus require tonnes of scrolling).
Use the Excel file as a dynamic data source. --Not entirely sure how I would go about doing this (any suggestions/links/tutorials etc)-- PROs: ? CONs: Contributor added this suggestion is not a good idea as it performs poorly on the web.
Create a dynamic page using a database and import the Excel file to that....or maintain the price list in the database rather than an Excel file. --Again not entirely sure how I would go about doing this (any suggestions/links/tutorials etc)-- My understanding of this option is that it will require XML data and SPRY work. Is this correct? Can this be someone who is not an advanced user?
If once again, I'm off the mark and better suggestions can be thought - please do so.
As you can see I'm at a bit of a crossroads so an suggestions, comment, help, links, tutorials or applause would be greatly received.
Thanks in advance and looking forward to seeing the comments this throws up!

Hi
Although not everyone has excel just about everyone can open csv files in some way, if not offer the option to download "open office" which is free for the pc, as for the mac they have a program installed by default to use csv files.
The import tabular data is not really an option for the reasons stated.
Use excel as data source - not a good idea, requires asp.net to work correctly otherwise it does run slow and is not recommended if you are expecting more than a very small number of users.
As for the dynamic with database, this can be done with xml and spry but if you have a large amount of data this is almost as bad as the option above. You are probably better creating a database and importing your excel spreadsheet into this, for tutorials on creating a php/mysql database and set-up of testing server see - http://www.adobe.com/devnet/dreamweaver/application_development.html.
No matter which way you go with the last option it will require a fair amount of knowledge and experience to do correctly, efficiently and securely.

Dynamic parameters data source

Database: Sybase ASA 9
Crystal: Developer 11 SP4 , activex viewer
Application: Powerbuilder 11
I am embedding crystal reports into a powerbuilder 11 application. The crystal reports (.rpt files) are created in Crystal reports developer 11 sp4. The application programmatically change the DSN for the crystal reports to connect to the database that the customer is using. This works fine except when the report contains dynamic parameters (parameter select values from table in database to select from). The dynamic parameter(s) still references the DSN used in development as appose to the new (changed) DSN , although the rest of the report use the "new" DSN. I have spend many many hours on this and are at a lost on how to fix this ?
Following is in short the code I use:
FOR li_table = 1 TO iole_crx_report.database.tables.count
// get connection properties collection for this table
iole_crx_connection_info = iole_crx_report.database.tablesli_table.connectionproperties
iole_crx_connection_info.DeleteAll()
iole_crx_connection_info.add("DSN",itrx_database_info.Lock )
iole_crx_connection_info.add("User ID",itrx_database_info.userid)
iole_crx_connection_info.add("Password", itrx_database_info.dbpass)
iole_crx_connection_info.add("UseDSNProperties",TRUE)
iole_crx_connection_info.add("AllowCustomConnection", TRUE)
NEXT
iole_crx_Database.Verify()

Hi Ludek,
Thanks for the reply.
The machine that I am testing on have an installed version of CR 11 SP4 development. I can change the report source for any report that does not have dynamic parameters. At the moment the reports that I am testing does not have subreports. It is a very simple two table report using dynamic parameters.
Changing the datasoure programmatically with both data sources (DB servers) running on the machine eveything works fine. When I refer to the two data sources I mean the data source that was used to create the report and the datatsource that I want to change to in the application to retrieve data from.
Does reports with dynamic parameters auto create subreports for the dynamic parameter(s) ?
I have tested this and it does not seem so. That could have possibly explained this.
I hope this gives you a clearer idea of what is happening?
