Can I change Data Source dinamically at runtime?

I need to execute the same reports on testing environment and production environment. How could I to change DataSource at runtime, depending on users want to execute reports querying testing database or production database without modifyng report definition?

Hi,
what I'd recommend in your case: setup your development/test systems as separate systems parallel to your production system. Clone your production environment to those development systems. Then a developer can login to the development system and run the reports (and modify there without touching real production system) and normal users work on the production system and just for validating the new developments they login to the test system.
That's a standard approach in software development and IT systems operations.
How does your infrastructure look, I have the impression that you have on BI server and two databases (prod and test)? Why not setting up a test environment for the BI server, too?
best regards,
David.

Change data source

Hi,
In portal EP6.0
In System Administrator->System Configuration->UM Configuration here in Data Source Tab already data source is assigned to "Read-only microsoft ADS ( Deep Hierarchy ) + Data base". I changed this data source to "Read-only SAP System + Data base" and saved.
But it is giving warninig message saying 'you are not allowed to select dataSourceConfiguration_R/3.xml as Active configuration file. This will lead to inconsistancy'.
How can we change data source?
Thanks in Adv.
Ganesh

Hi Ganesh,
You want to change the configuration to this "Read-only SAP System + Data base" rite ?
Dont change from here -System Administrator->System Configuration->UM Configuration in Data Source Tab
Start the Config Tool by executing j2eeconfigtoolconfigtool.bat.
Switch to Edit mode.
In the tree, navigate to Global server configuration ® services ® com.sap.security.core.ume.service
Here change the value of the property ume.persistence.data_source_configuration to the one you want to apply(for example dataSourceConfiguration_R/3.xml)
Click on "Apply Custom" Save the changes.
Restart the cluster.
This should work.
Let me know if you need any other help.
Thanks,
Samta

I can not map field after changing data source location

Hi
I have a small problem that I got a report file and database from my customer, after that I setup database, open the file and change data source to my setting. but some filed can not map. The field mapping widonw does not display all field in the table. Of course I have checked the missing fields are existing in the table.
OS:Windows7
DB:Oracle11
CR:XI Release 2
Does anyone have an idea?

hi,
In Map Fields window, there is an option "Match Type".
Please Unchek that option, so that you will be able to see all the fields from that table.
Also, while mapping please verify the datatypes of source and target fields.

Thanks in advance.You have to use Reports Trigger named BEFORE PARAMETER FORM and write the following sql
select sysdate into :Parameter_name from dual;
give your format mask at Parameter_name.
Hope this will help you

Change data source dynamically

is it possible to change data source dynamically when using ibatis frame work...?

We don't need a Java reporting tool to change data source dynamically.
In Oracle Reports we can use:
- lexical parameters
- dynamic ref cursors
- XML runtime customization

903/902/BC4J can't get data-sources.xml conn pooling to work in production; help

I have several BC4J ears deployed to a 903 instance of OC4J being configured as a standalone
instance. I've had this problem since I started deploying in development on 902. So it's
some basic problem that I've not mastered.
I can't get data-sources.xml managed connection pooling to actually pool conn's. I'm wanting
to declare my jndi jdbc source connection pool in j2ee/home/config/data-sources.xml.
Have all BC4J apps get conns from this JNDI JDBC pool. I've removed all data-sources.xml from my BC4J ears,
and published the jndi jdbc source in my oc4j common data-sources.xml. I've tested that this is
the place controlling the conn URL/login passwd by commenting it out of config/data-sources.xml
and my BC4J apps then throw exceptions, can't get conn.
I've set the oc4j startup cmd line with the BC4J property to enabled connection pooling:
-Djbo.doconnectionpooling=true
symptom
Connections are created and closed. Instead of being put back into the pool managed by oc4j,
what ever BC4J is doing or my data-sources.xml is doing, the connections are just being created and
closed.
I can verify this via (solaris) lsof and netstat, where I see my oc4j instance under test load
with only 1 or 2 conns to the db box, and the ephemeral port is tumbling, meaning a new socket is
being opened for each conn. ;( grrrrrrr
Does anyone have a clue as to why this is happening?
Thanks, curt
my data-sources.xml
<data-sources>
 <data-source
 class="com.evermind.sql.DriverManagerDataSource"
 connection-driver="oracle.jdbc.driver.OracleDriver"
 ejb-location="jdbc/DEVDS"
 location="jdbc/DEVCoreDS"
 name="DEVDS"
 password="j2train"
 pooled-location="jdbc/DEVPooledDS"
 url="jdbc:oracle:thin:@10.2.1.30:1521:GDOC"
 username="jscribe"
 xa-location="jdbc/xa/DEVXADS"
 inactivity-timeout="300"
 max-connections="50"
 min-connections="40"
 />
</data-sources>

I've run another test using local data-source.xml, that's packaged in the .ear. Still
pooling under BC4J doesn't work??
A piece of info is that the 903 oc4j release notes states that global conn pooling doesn't
work. Infering that the j2ee/home/config/data-sources.xml data sources aren't pooled or ??
I just tested so called local connection pooling, where I edited the data-sources.xml that
gets packaged in the ear, to include the min/max params and re-ran my test.
Still, the AM creates a new conn, it's to a new socket, and closes the conn when done. Causing
each conn to not be pooled, rather opened then closed to the DB box. As verified with lsof and
netstat, checking the ephemeral port # on the DB box side, always changes, meaning it's a
new socket and not an old pooled conn socket.
???? What the heck??
Surely if the AM conn check out / return code works properly, OC4J's pooling JDBC driver would
pool and not close the socket??
Has anywone gotten JDBC Datasource connections in BC4J to actually be pooled under OC4J??
Since I couldn't get this to work in my early 902 oc4j testing, and now can't get it to work
still under 903 OC4J, either it's my config or BC4J AM's code or OC4J?
Any thoughts on how to figure out what's not configed correctly or has a bug?
Thanks, curt

How to change data source name and context root during deployment

Hi,
Env:
WLS 10.1.3
JDev 11.1.1.6
Hudson
I need to deploy two instances of my ADF application on the same development enviroment. We are using Hudson to deploy. My question is how to change data source name and application context root before second deployment.
Kuba

I don't believe there is an inbuilt facility to do this.
Previously how I've done this is when checking files out using Hudson jovs, before the build I then use an Ant extension called XmlTask (http://www.oopsconsultancy.com/software/xmltask/) to modify the required XML files.
Can I ask why you're doing this in the first place please? Multi-tenancy? 2 versions of the same app?

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
Viswa

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.

Trying to Change Data Source but is not highlighted

I have a pivot table running with inventory and we are doing a server upgrade so i need to change the path, but the "Change Data Source" button is not lit up and will not let me do this. Anyone know why this might be happening? Thanks!!!

Hi Frank,
We can directly update the existing connection string to connect to new server. Please take a look at the following articles:

Can we change data in string object.

Can we change data in string object.

Saw this hack to access the char[]'s in a String in another thread. Beware that the effects of doing this is possible errors, like incorrect hashCode etc.
import java.lang.reflect.*;
public class SharedString {
        public static Constructor stringWrap = null;
        public static String wrap(char[] value, int offset, int length) {
                try {
                        if (stringWrap == null) {
                                stringWrap = String.class.getDeclaredConstructor(new Class[] { Integer.TYPE, Integer.TYPE, char[].class });
                                stringWrap.setAccessible(true);
                        return (String)stringWrap.newInstance(new Object[] { new Integer(offset), new Integer(length), value });
                catch (java.lang.NoSuchMethodException e) {
                        System.err.println ("NoMethod exception caught: " + e);
                catch (java.lang.IllegalAccessException e) {
                        System.err.println ("Access exception caught: " + e);
                catch (java.lang.InstantiationException e) {
                        System.err.println ("Instantiation exception caught: " + e);
                catch (java.lang.reflect.InvocationTargetException e) {
                        System.err.println ("Invocation exception caught: " + e);
                return null;
        public static void main(String[] args) {
                char[] chars = new char[] { 'l', 'e', 'v', 'i', '_', 'h' };
                String test = SharedString.wrap(chars, 0, chars.length);
                System.out.println("String test = " + test);
                chars[0] = 'k';
                chars[1] = 'a';
                chars[2] = 'l';
                chars[3] = 'l';
                chars[4] = 'a';
                chars[5] = 'n';

How can you change data on a SQL 2012 application database that uses availability groups from BizTalk server?

If you use the WCF-SQL adapter it is recommend that you set UseAmbientTransaction to true if you are changing data. I think this requires MSDTC to be enabled on the SQL server that you are changing the data on. (http://msdn.microsoft.com/en-us/library/dd787981.aspx)
I think that Availability groups does not support MSDTC. (http://msdn.microsoft.com/en-us/library/ms366279.aspx).
