Dynamically creating DataSources

Our current client requirements dictates that as new Engineering projects are started that a seperate instance of our Engineering database needs to be set up. I have a login screen in which a user enters the project number they need to connect to and the application then connects to the correct DataSource and everything works as planned. However, new projects are added daily and I need to be made aware of the additions and update the datasources.xml then restart oc4j. This is becoming a maintenence nightmare. The way I plan on circumventing this is to catch the NamingException when a lookup on a nonexistent datasource is done then dynamically create the datasource by modifing the datasources.xml file. This I have succeeded in doing but the oc4j container still requires a restart. Can I programitically bind the required datasources to the JNDI tree so they are available without a restart or is there some other way I could accomplish this.

Buster -- You cannot programmatically bind the data source but you could call out to admin.jar to create a new data source for you and then you do not need to restart OC4J.
Thanks -- Jeff

Hi John,
weblogic 5.1 doesn't have API allowing dynamic creation
of datasources. 6.1 does.

How dynamically create connection pool and Datasource

Hi
How I can dynamically create a connection pool and Data source in Oracle 10g Application server. In our J2EE application the user will be login with db user name, password and database name. I want to create connection pool and data source on the fly while login the user with database name. I our application we have access approximate 80 Databases. so my approach is given bellow
1) Planning to create 80 connection pools and 80 Data sources so when user logs in while selecting the db name i will call the appropriate data source and create the DB connection. Is there any limitation to create number of data sources in oracle app server?
2) Create DB connection with out using connection pool and data source. But i am not prefer this approach coz we need to handle some transaction in our application.
Kindly throw some light on managing connection pool programmatically or in application run time.
I would really appreciate if any one can provide any links or any inormation on this issue.
Thanks in advance.

Kindly let me know is there any drawbacks to create 80 Data Sources to connect 80 database in Oracle 10G App server and each data sources should have one connection pool. so i need to create 80 connection pool. Please let me know is this right approach or any work around to create Data source on fly for each request for corresponding database.

Cannot Create Datasource through Java Application

Hi All,
I tried to create a datasource through my Java application
JDBCDescriptor jdbcDescriptor = new JDBCDescriptor();
          jdbcDescriptor.setDataSourceName("ds_venky");
          jdbcDescriptor.setDriverClassName("org.gjt.mm.mysql.Driver");
          jdbcDescriptor.setDriverName("mysql");
          jdbcDescriptor.setInitConnections(2);
          jdbcDescriptor.setMaxConnections(10);
          jdbcDescriptor.setPassword("xxxx");
          jdbcDescriptor.setURL("jdbc:mysql://172.22.76.8:3306/wise");
          jdbcDescriptor.setUsername("xxxx");
Properties ctxProp = new Properties();
               ctxProp.put(
                    Context.INITIAL_CONTEXT_FACTORY,
                    "com.sap.engine.services.jndi.InitialContextFactoryImpl");
               ctxProp.put(Context.PROVIDER_URL, "myServerName:50004");
               ctxProp.put(Context.SECURITY_PRINCIPAL, "xxxx");
               ctxProp.put(Context.SECURITY_CREDENTIALS, "xxxx");
               InitialContext context = new InitialContext(ctxProp);
               DataSourceManager dsm =
                    (DataSourceManager) context.lookup("dbpool");
               dsm.createDataSource("ds_venky", jdbcDescriptor);
But i get the following exception

How to create datasource/connection pool programatically?

Hello,
We are developing a system that connects to multiple databases by dynamically switching datasources, using ADF 12.1.3. Application is deployed on weblogic and glassfish.
There is no problem on switching and working on multiple datasources which is created previously on the application server (weblogic/glassfish).
Now we need to create a datasource while system is running.
Is it possible to create datasource programatically, and list datasource previously created?
Jdeveloper/ADF: 12.1.3.
Thanks,
Ganbat Bayarbaatar.

Dear Ashish,
Thank you for your response, but that is not what I was looking for.
I haven't any problem on changing datasources. I would like to create new datasource on application server.
On Andrejus's post, there is a comment about what I'm asking:
Syed : Nice Post. To enhace this more further. How can we get list of JDBC Data sources available in weblogic in the ADF Application.
Andrejus: By using WebLogic API this should be possible or by accessing MBean...
Is there any more-detailed blog post or doc, about "Weblogic API", "MBean" and using them to create datasource?
Thanks,
Ganbat.

Problem with embeding the same view in dynamically created view container

Hello Experts,
              I am getiing a dump when i try to embed the same view inside the dynamically created view container of
dynamically created tabs of a tabstrip
The requirement go like this, i have 2 views in which i have have to embed the 2nd view to view1 where i have an empty
tabstrip without tabs. During runtime i create tabs as well as view containers accordingly and then try to embed view2 in tabs.
I have put the below mentioned code in HANDLEIN,
DATA: lref_vcntlr TYPE REF TO if_wd_view_controller,
        lref_comp    TYPE REF TO if_wd_component_usage,
        lv_embed_pos TYPE string.
lref_vcntlr = wd_this->wd_get_api( ).
lv_embed_pos = 'FILE_PERS_EDIT/VC_GENERAL'.
TRY.
      CALL METHOD lref_vcntlr->do_dynamic_navigation
        EXPORTING
          source_window_name        = 'FILE_PERSISTENCE_WND'          " Window
          source_vusage_name        = 'FILE_PERS_EDIT_USAGE_1'       " Source View usage
          source_plug_name          = 'TO_EDIT_LAYOUT'                       " Outbound plug
          target_view_name          = 'PERS_EDIT_LAYOUT'                  " Second view to be embedded
          target_plug_name          = 'IN'                                                  " Second view inboun plug
          target_embedding_position = lv_embed_pos
        RECEIVING
          component_usage           = lref_comp.
    CATCH cx_wd_runtime_repository .
ENDTRY.
wd_this->fire_to_edit_layout_plg( ).
This works fine for the first time.
However onaction tab select i change the embeding position( 'FILE_PERS_EDIT/view container name of different tab') of the view2 an try to embed view2 in a different tab.
At this point i get a dump stating View2 already present in the window 'FILE_PERSISTENCE_WND' of component.
I think, the view2 embediing has to be removed before i add the view2 in a different tab
Kindly let me know how to remove view2 embedding from tab1 before i add a view2 to a different tab or is there any other
means to handle this problem?
Thanks & Best Regards,
Srini.

Hello Srini,
I found a solution to your problem, because I had a similar task.
In WDDOINIT I changed the method do_dynamic_navigation to if_wd_navigation_services_new~prepare_dynamic_navigation:
DATA:
    l_view_controller_api TYPE REF TO if_wd_view_controller.

How can i create datasource on apache server for ADF application?

Hi All,
i my use case i have created simple adf application using ADF BC and want to deploy on Apache server 6.x.
So my question is that how can i create Data Source i have goggling and find two different way to do this.
1. write following line of code on apache server conf/Context.xml file.
<Resource name="jdbc/TestDB" auth="Container"
              type="javax.sql.DataSource"
               driverClassName="oracle.jdbc.OracleDriver"
              url="jdbc:oracle:thin:@localhost:dst"
              username="jagrandb" password="jagrantest" maxActive="20" maxIdle="10"
              maxWait="-1"/>
but when i have used this way i got following exception.
org.apache.tomcat.dbcp.dbcp.PoolingDataSource$PoolGuardConnectionWrapper cannot be cast to oracle.jdbc.OracleConnection
check link-
https://forums.oracle.com/thread/2564233
2. write following line of code apache conf/Server.xml file
<GlobalNamingResources>
    
    <Resource name="UserDatabase" auth="Container"
              type="org.apache.catalina.UserDatabase"
              description="User database that can be updated and saved"
              factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
              pathname="conf/tomcat-users.xml" />
<Resource name="jdbc/TestDB" auth="Container"
              type="oracle.jdbc.pool.OracleDataSource"
              description="User database that can be updated and saved"
              driverClassName="oracle.jdbc.driver.OracleDriver"
              factory="oracle.jdbc.pool.OracleDataSourceFactory"
              url="jdbc:oracle:thin:@//172.31.43.207:1521:dst"
              username="jagrandb" password="jagrantest" maxActive="20" maxIdle="10"
              maxWait="-1"   />
</GlobalNamingResources>
and add this line in context.xml file inside <context> tag
<ResourceLink global="jdbc/TestDB" name="jdbc/TestDB" type="oracle.jdbc.pool.OracleDataSource"/>
but when i have run application i have got following error

Hi Lindalnci
i have already tried this tutorial and in my post i have defined first way to do using this procedure.
in that case i have got following exception as i have mentioned above
org.apache.tomcat.dbcp.dbcp.PoolingDataSource$PoolGuardConnectionWrapper cannot be cast to oracle.jdbc.OracleConnection

Is there a way to use a statically defined appearance stream in a dynamically created annotation?

Hello,
I want to create a document with cascading 'popups'. Not the built-in text-only popup, but an annotation containing an appearance stream that defines text and images. I'm currently using widget annotations based on a pushbutton field.
Each page in my document has many citations that refer to other pages in the document. When a user hovers over the citation, I want a 'popup' to appear containing a depiction of the destination. However, as the destination will itself have citations, I also want the 'popup' to contain citations that the user can hover over, triggering another popup, etc. In this way, a user could navigate throughout the document without leaving the page or even clicking the mouse.
Obviously, with even a modest number of citations per page, pre-calculating and statically defining all of these widgets causes a combinatorial explosion, making the document sluggish and very large.
Instead, I'd like to statically define appearance streams once per document, and then dynamically create annotations and assign the appropriate appearance stream using JS as the user navigates.
So far I've created a named AP in the names dictionary, but I haven't been able to use it to dynamically set an appearance stream of a dynamically created widget annotation.
Also, I've called Doc.getIcon(), passing in the named AP, which returns an Icon object. However, after field.buttonSetIcon() and passing in the named AP, the button does not display the icon.
Is there a way to use a statically defined appearance stream in a dynamically created annotation?
Thank you,
Dave

Hi George, I've gotten named APs to work, and I expect hidden buttons will follow. Thank you very much!
Quick follow-up - I will have many documents embedded within the same pdf file, and some of these documents will contain identical popups. However, I don't want to store identical icons in each document on account of file size.
Instead, I'd like to store one instance of each icon for all documents in the file.
Can I store all of the icons in a single document, and then access them by calling <DocName>.getField().getIcon() from any document in the file?
Thank you again,
Dave

Creating Datasource and Extracting from SAP R/3 ECC 6.0

Hello Gurus,
I am very new in BI field, I am learning through notes provided in this Blog.
Curretnly I need to know how we create Datasource at SAP R/3 ECC 6.0 (is there any difference b/t these?)
and how we may extract data from R/3 ECC 6.0 Source System.
Looking for your kind reply
Thanks in Advance
KK

You can use any specific Extractors to Create Data Source in R/3 side.
Let me explain with Generic Extraction
Goto SBIW--> you can see all the extractions here
Generic extractors are of 3 types:
1. Based on table/view
2. Based on Info set Query
3. Based on Function module
If you would like to create a custom table, then goto SE11>Select Table>Click on Create (Now create you own table here & use this table while creating Transaction data)
Goto RS02-->Select Transaction data.
Click on Create
Choose an application component to which the data source is to be assigned
Click on Generic Delta
Specify the Delta-Specific and the type for the field.
Specify a safety interval
Select Data type>Save> Now Data source was generated successfully
After generating the data source , you will find Delta Flag checked.
Please go through the following link for Generic Delta
[https://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/84bf4d68-0601-0010-13b5-b062adbb3e33]
Once you've done with Data Source in R/3 side--> u need to Replicate it to BI
Goto RSA1>source system>Select the Source system in which u've created Data source>R.C select Data Source Overview>Select the Application Component to which Data source is assigned>R.C Select Replicate dataSorce>here you can see your NEW Data source
Hope it helps!

Table for creating datasource .

Hi Experts
I am trying to create a report.
The report output is as follows
Companycode | business partner type | Business partner No | vendor no | customer no |cheque no | cheque date | cheque amount | check status | bank account no |.

Hi,
There is no provision in WD for getting screen coordinates and then placing the UI element.
You to add the UI element to layout editor and based on the layout type it will add the UI element to respective position.
I would advice not to create dynamic UI elements( instead you can create them statically and then play with visibility status through context binding ). This will be more effective way and less error prone. This is also recommended practice.
still,For dynamic creation you can refer to following wiki:

Error while creating datasource from table MBEWH

Hi all,
I am facing an error message while creating datasource from table MBEWH
"Invalid extract structure template MBEWH of DataSource "; This operation failed, because the template structure quantity fields or currency fields, for example, field LBKUM refer to a different table.
Can anyone help me that why system is not allowing me to generate generic datasource for table MBEWH to transfer my month wise inventory data.
thanks and regards.

Hi Zakir,
      This was comming for classification data... when ever you want to extract some classification related data then we can't create generic datasources directly.. for that you need to go with CTBW ( tcode ) and   create one datasource...
   so, you need to check that   related table also.. for that MBEWH table..
    ALL THE CLASSIFICATION RELATED DATASOURCES WE CAN'T CREATE DIRECTLY... JUST LIKE AUSP table also.. liek this..

Error while creating datasource userdsn for oracle 10g Errorcode (998)

while creating datasource userdsn for oracle 10g i am getting error "The setup routines for the oracle in OraDb10g_home1 odbc driver could not be loaded due to system error code 998" please give reply soon

Thanks for your reply , Steve.
I noticed that there is a default datasouce on the EM with the following parameters:
<data-source
          class="com.evermind.sql.DriverManagerDataSource"
          name="OracleDS"
          location="jdbc/OracleCoreDS"
          xa-location="jdbc/xa/OracleXADS"
          ejb-location="jdbc/OracleDS"
          connection-driver="oracle.jdbc.driver.OracleDriver"
          username="scott"
          password="->pwForScott"
          url="jdbc:oracle:thin:@localhost:1521:oracle"
          inactivity-timeout="30"
     />
The location and xa-location attributes that I use for my "test" data source are the same as the default one. So, could this be the issue?
What should be the values for location and xa-location attributes from my "test" data source?
Any help will be greatly appreciated.
Thanks,
Shyam

Error while creating datasource from view ZBSIS_VIEW

Hi all,
I could not create the datasource on the database table BSIS as it said "Invalid extract structure template BSIS of Datasource". I had suggestions that I should create a view and then create the Datasource on it. So I created the view and tried. But still I am facing an error message while creating datasource from custom Database View ZBSIS_VIEW.
"Invalid extract structure template ZBSIS_VIEW of DataSource"
Can anyone help on this regard.
thanks.

Hi,
Yes. You need a create a view on tables BSIS, BKPF and T001 as the currency/quantity fields in BSIS have reference fields from the other 2 tables.
In BSIS, in the currency/quantity fields tab, you have some ref tables and fields. You would need to include these tables and join in the view. You would also need to include the ref fields like WAERS, HWAE2, HWAE3, etc in the view. Then you would be able to create the datasource.
