How connect to DataSource in iAS

I have set up the Oracle thin client and create a Data Source in the iAS
server. Is it possible to access the DataSource from an application outside
iAS using JNDI? Thanks for anyone who can give some samples or pointers
related to this.
Regards,
Keith

Thanks for your reply, Anuj.
But after I updated the DB Adapter I received a set of new error report.
Exception occured when binding was invoked.
Exception occured during invocation of JCA binding: "JCA Binding execute of Reference operation 'queryByExample' failed due to: JCA Binding Component connection issue.
JCA Binding Component is unable to create an outbound JCA (CCI) connection.
*IMS2MRDBapp:FeiYeConn [ FeiYeConn_ptt::queryByExample(Mrdblite,MrdbliteCollection) ] : The JCA Binding Component was unable to establish an outbound JCA CCI connection due to the following issue: javax.resource.spi.IllegalStateException: [Connector:199176]Unable to execute allocateConnection(...) on ConnectionManager. A stale Connection Factory or Connection Handle may be used. The connection pool associated with it has already been destroyed. Try to re-lookup Connection Factory eis/DB/FeiYeConn from JNDI and get a new Connection Handle.*
*The invoked JCA adapter raised a resource exception.*
Then after I check the data source and find nothing wrong, I test the project again, it gives me another error report still about connection:
*Exception occured when binding was invoked.*
*Exception occured during invocation of JCA binding: "JCA Binding execute of Reference operation 'queryByExample' failed due to: Could not create/access the TopLink Session.*
This session is used to connect to the datastore.
Caused by java.lang.ClassCastException: oracle.tip.adapter.db.DBConnectionFactory.
*The invoked JCA adapter raised a resource exception.*
*Please examine the above error message carefully to determine a resolution.*
it's now again similar with the first time I posted.
Any idea what can I do now?

How to use DataSource and External transaction in 9ias?

I'm working on a project that the application server needs to connect to over 100 databases.
I'd like to use connection pooling and external transaction service defined in OC4J's Datasources.
I wonder if anyone has an example of using datasource and external transaction service for OC4J.
Right now, I export toplink project to a java source and do the initialization there manually but I don't know how to use Datasource to get connections and how to use the external transaction service in the java code for OC4J.
I really appreciate you help.
Wei

Here is a fill in the blank example on how you could set this up through code:
Project project = new MyProject();
// alternatively, use the XMLProjectReader
server = project.createServerSession();
server.getLogin().useExternalConnectionPooling();
server.getLogin().setConnector(new JNDIConnector(new javax.naming.InitialContext(), "jdbc/DataSourceName"));
// the next line depends on the type of driver you want to use.
server.getLogin().useOracleThinJDBCDriver();
server.getLogin().useOracle();
server.getLogin().setUserName("username");
server.getLogin().setPassword("password");
server.getLogin().useExternalTransactionController();
server.setExternalTransactionController(new Oracle9iJTSExternalTransactionController());
server.logMessages();
server.login();

You will need to use the JSR 88 API to access deployment descriptor configuration.

How to Upgrade datasources from 3x to 7x versions

Hi Experts
How to Upgrade datasources from 3x to 7x versions.
I am planning to upgrade exisisting 3x data sources which are used in data loading are there any risks involved in upgrade
Thanks

Hi,
When you migrate a 3.x DataSource (R3TR ISFS) in an original system, the system generates a DataSource (R3TR RSDS) with a transport connection. The 3.x DataSource is deleted, along with the 3.x metadata object mapping (R3TR ISMP) and transfer structure (R3TR ISTS), which are dependent on it. If a PSA and InfoPackages (R3TR ISIP) already exist for the 3.x DataSource, they are transferred to the migrated DataSource, along with the requests that have already been loaded. After migration, only the specifications about how data is loaded into the PSA are used in the InfoPackage.
You can export the 3.x objects, 3.x DataSource, mapping and transfer structure during the migration so that these objects can be restored. The collected and serialized objects are stored in a local table (RSDSEXPORT).
You can now transport the migration into the target system.
When you import the transport into the target system in the after-import, the system migrates the 3.x DataSource (R3TR ISFS) (as long as it is available in the target system) to a local DataSource (R3TR RSDS), without exporting the objects that are to be deleted. The 3.x DataSource, mapping (R3TR ISMP) and transfer structure (R3TR ISTS) objects are deleted and the related InfoPackages are migrated. The data in the DataSource (R3TR RSDS) is transferred to the PSA.

Suman

How connect a 27 cinema display to HP Pavilion with VGA video output

how connect a 27 cinema display to HP Pavilion with VGA video output

If it is a thunderbolt version of the apple 27" display, you don't. The TB displays can only work with a TB source.
I also think you are out of luck with the mini-displayport versions of the apple 27" as well. This would imply converting an analog VGA output to a digital input of the 27". I suspect that there is not enough data supplied by VGA for that to work and I do not believe any adapters exist for this.

BI 7.0: How to bring DataSource fields to InfoSource in design

We've replicated the generic datasource from R3 to BW and we have created an InfoSource with blank fields. We remember on BW 3.x version that we could bring Datasource fields to InfoSource by clicking somewhere, but on BI 7.0, we are trying to do the same thing, but can't find some function to do this. Then we try to right click the InfoSource and then select 'Create Transformation', and then to select the source system and the datasource, but of course we would get the error msg like "There are no fields in target TRCS InfoSource_Technical_Name". Any idea on how to bring Datasource fields into the blank InfoSource on BI 7.0?
Thanks!

Hi,
Instead of bringing the DS fields into a blank infosource, ideally, what you can do
is, you can create a new infosource based on your generic data source, which would make your process easy..
cheers,
Pattan.

How connect External monitor to iMac?

How connect External monitor to iMac?

How to do that depends on the iMac variant you have. iMacs have been in continuous production since 1998 in four broad families that are not 100 percent alike in behavior.
Please look at the iMac images and descriptions in the links on this site:
http://www.everymac.com/systems/apple/imac/index-imac.html
and tell us what variant you believe you have.
iMacs from the first through third-generations (G3, G4, and G5 processors) that support an external monitor were not set up to do anything other than "mirroring"--you see on the external exactly what is on the built-in display.
Your description sounds like you have a newer iMac than this forum covers because, starting with the Intel iMacs in 2006, external monitors were allowed to do both mirroring and "extended desktop." The latter is what I believe you are seeing.
Try this first: press the F7 key. On many Macs capable fo using external monitors, this was a shortcut to toggle between mirrored and extended display. If your keyboard has an "fn" modifier key, you may need to press that to get the F7 key to work.
If you have an intel-powered iMac I can ask the Hosts to move you to that forum, which is much more active than this one which is for pre-2006 iMacs.

Hi Les,
in R/3 Tcode CMOD and create, if does not already exist a project, for example ZBW1 (is simply a definition). Then enter in Components of the project selecting the corresponding flag and then select EXIT_SAPLRSAP_002 Exit Function.
Then double click on the word ZXRSAU... at the right of word INCLUDE.
In the next screen you introduce your code.
Hereunder an example for vendor:
DATA: L_BIW_LFA1_S LIKE BIW_LFA1_S,
 l_tabix LIKE sy-tabix.
CASE i_datasource. (this is always necessary)
WHEN '0VENDOR_ATTR'.
 LOOP AT i_t_data INTO l_BIW_LFA1_S.
 l_tabix = sy-tabix.
 SELECT XEGLD FROM T005
 INTO V_XEGLD
 WHERE LAND1 = l_BIW_LFA1_S-LAND1.
 IF V_XEGLD = ' '.
 l_BIW_LFA1_S-ZZXEGLD = 'E'.
 ELSE.
 IF l_BIW_LFA1_S-LAND1 = 'IT'.

 ENDIF.
 ENDIF.
 ENDSELECT.
 MODIFY i_t_data FROM l_BIW_LFA1_S INDEX l_tabix.
 ENDLOOP.
ENDCASE. (this is always necessary)
Ciao.

How to generate datasource for inforsource in BW 7

Hi all:
Could you please tell me how to generate datasource for inforsource in BW7, it seems that the way
is different from other lower edition BW 3.x. Should I choose Tranformation ? and then how ?
Thank you very much!
Edited by: jingying Sony on May 9, 2009 8:41 AM

1) First thing is that in BI 7.x the infosource is optional.You can directly create a transformation between datasource and data target (e.g. cube). If you still want to use a infosource then you will require 2 transformations. 1 will act as a transfer rule and other one will act as a update rule. This is a crude example showing the comparision between 3.x and 7.x.
2) Infopackage in 7.x will load the data only till PSA. From PSA to data target you will need DTP. DTP will load data from PSA to data target. So you need to ensure you create a complete flow from datasource to data target and create infopackage & DTP.
