Setting a data source for a tableView

Greetings
I'm trying to learn cocoa touch by following the Apple's code example called SQLiteBooks.
there is a data source assignment within the MasterViewController code:
- (void)loadView {
tableView = [[[UITableView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame] style:UITableViewStylePlain] autorelease];
tableView.delegate = self;
tableView.dataSource = self;
self.view = tableView; }
Can anybody explain how "tableView.dataSource = self" associates an NSArray "books", which actually has the data, with this tableView?
Best regards,
-Eugene

I can give you a Cocoa-specific answer. Unfortunately, with the new iPhone SDK there are tons of new people posting questions about the iPhone. That is why I didn't respond yesterday. My answer may or may not make sense for the iPhone.
When you setup a data source, the table view will call two methods on that data source to get data. It will call "numberOfRowsInTableView:" to get the number of data elements and "tableView:objectValueForTableColumn:row:" to get a specific value for a cell.
Your data source should implement those methods and return data for the table view to dipslay.
Full details are available in Apple's documentation

Trying to programmatically set the data-source for a Crystal reports report.

I've got the following existing procedure that I need to add to in order to programmatically set the data-source (server, database, username, and password) for a Crystal reports report.
I added the connectionInfo parts, but can’t figure out how to attach this to the existing
this._report object.
This is currently getting the connection data from the report file, but I now need to populate this connection data from a 'config.xml' text file.
Am I trying to do this all wrong?

Cannot set up data source for SQL Server 2005

Is it possible to use Microsoft's Beta 2 version of the SQL Server 2005 JDBC driver with WebLogic 9.0? I've downloaded the driver and added it to my server classpath, but when I try to create a new data source using the admin console, the drop-down list for Microsoft SQL Server only contains drivers for the 2000 version. If I select "Other" from the list and try to move on, I get a cryptic, page-long error on the admin console. If I just select the 2000 driver and try to manually modify the parameters on the next set of screens, I still get errors when I try to test the configuration. I've successfully used a third-party driver before, but this one does not seem to be working. Any help would be greatly appreciated.

Sabrina

on the next set of screens, I still get errors when I try to test the configuration. I've successfully used a third-party driver before, but this one does not seem to be working. Any help would be greatly appreciated.
Regards,
SabrinaHere I describe the steps I took to bypass the console in making a new pool.
1 - Edit the script %DOMAIN_HOME%\bin\startWebLogic.cmd to add a line like this:
set CLASSPATH=%CLASSPATH%;\new_ms_driver\beta2\sqljdbc_1.0\enu\sqljdbc.jar
In other words, you have to explicitly add a third party driver's classes to
the CLASSPATH that will be in effect for the server. Just adding the driver
to your window's class path will do nothing.
2 - Go to the directory %DOMAIN_HOME%\config\jdbc, where you will find
files of the name *-jdbc.xml. Each of these represents a DataSource.
Copy one of them, perhaps either examples-demo-jdbc.xml, or
examples-demoXA-jdbc.xml depending on whether you want to make an XA
or non-XA pool. Make you new file's name like the name of the DataSource,
still ending in -jdbc.xml. Eg: MS_Beta-jdbc.xml
3 - Edit this file to change as much as would be clear for the
driver you want. Eg: change the driver class to the class you want,
the user name, URL, test table etc. Also, change the pool's initial
capacity to 0. This is so the pool can be created without making a
connection. We need that because the password is encrypted, and
there is no manual way for you to add the correct one yet.
4 - go one directory up, and edit the config.xml. Find a
jdbc-system-resource entry corresponding to the original
resource file you copied. Make a new entry in the config file,
like the original, but change the Datasource name to your new one.
5 - If this all went well, reboot your server and go to your data
source in the console, and edit it. Alter the password to what it
really should be, and you can also change whatever else you might
want.
6 - shut down again, and reboot, and you should then be able to go to
your data source in the console and test a connection.
That's it. Here is an example of a jdbc.xml file I made, and
the entry I made in the config.xml:
config/jdbc/newpool-jdbc.xml:
<?xml version='1.0' encoding='UTF-8'?>

How to set up data source for JDeveloper's embedded OC4J Server?

Help needed. I Created a BMP EJB and tried to test
it with JDeveloper's( version 9.0.3) embedded
OC4J server. For JDBC, I created a data source
in data-source.xml lacated in JdeveloperHome\j2ee\home\config. However,
when I run the test client. I got the error
from JNDI lookup:
java.rmi.RemoteException: jdbc/entdatasource not found
Could anybody with similar experience help?
Thank you in advance.
-John Wang

Try making your changes in the data-source.xml located @ JDev_root\jdev\system9.0.3.1035\oc4j-config.
You can tell that this is the one to be modified by watching the log when you start the OC4J server. Look for the line that says C:\JDEV\JDK\bin\javaw.exe -ojvm -classpath . . .
the -config option will point to where the server.xml is used from, the same dir should be where you get your data-source.xml

How to set JDBC Data Sources in Oracle MapViewer for Oracle database 12c Release 1 (12.1.0.1)

How to set JDBC Data Sources in Oracle MapViewer for Oracle database 12c Release 1 (12.1.0.1)?
The following is my configuration in the conf\mapViewerConfig.xml:
<map_data_source name="mvdemo12"
jdbc_host="127.0.0.1"
jdbc_sid="orcl12c1"
jdbc_port="1522"
jdbc_user="mvdemo"
jdbc_password="7OVl2rJ+hOYxG5T3vKJQb+hW4NPgy9EN"
jdbc_mode="thin"
number_of_mappers="3"
allow_jdbc_theme_based_foi="true"
editable="true"/>

But it does not work.
After use "sqlplus mvdemo/[email protected]:1522/pdborcl", it connected to the Oracle database 12c.
Does anyone know it?
Thanks,

For 11.1.1.7.1 use the syntax for jdbc_sid, i.e.
//mypdb1.foo.com as described in the README,
- MapViewer native (non-container) data sources can now use database service name in place of SID. To supply a db service name, you will use the same jdbc_sid attribute, but specify the service name with double slashes in front, such as follows:
<map_data_source name="myds"
 jdbc_host="foo.com"
 jdbc_sid="//mypdb1.foo.com"
 jdbc_port="1522"
/>
For 11.1.1.7.0 use a container_ds instead.
i.e. instead of using
<map_data_source name="my_12c_test"
 jdbc_host="mydbinstance"
 jdbc_sid="pdborcl12c"
 jdbc_port="1522"
 jdbc_user="mytestuser"
 jdbc_password="m2E7T48U3LfRjKwR0YFETQcjNb4gCMLG8/X0KWjO00Q="
 jdbc_mode="thin"
 number_of_mappers="6"
 allow_jdbc_theme_based_foi="false"
 editable="false"
 />
use
<map_data_source name="my_12c_test"
 container_ds="jdbc/db12c"
 number_of_mappers="6"
 allow_jdbc_theme_based_foi="false"
 editable="false"
 />
In my case the Glassfish 3.1.2.2 JDBC connection pool definition was
Property
url jdbc:oracle:thin:@mydbinstance:1522/pdborcl12c.rest_of.service.name
Uncheck the Wrap JDBC Objects option in Advanced panel, i.e. the Edit JDBC Connection Pool Advanced properties page.
Add a JDBC resource for that newly created pool
Use that in mapviewerconfig.xml as above

Using Oracle BI Server as a Data Source for Third Party Tools

I have been researching how to use the Oracle BI Server as a data source for two days now. I have not yet found a solution to my problem.
We have a remote user who is pulling data from one of our Oracle databases using automated tools. This data base is essentially being replaced by Oracle Analytics. However, we do not want this user to get at the physical tables of Analytics, rather, we want the user to be able to connect to the Oracle BI Server itself, and issue Logical SQL to pull data.
Here are the requirements which I need to be fulfilled:
1) The ability for a remote user to connect to the BI Server as a data source.
2) The remote user must be able to do this on a Unix box.
3) The remote user must be able to automate the process of issuing SQL to the BI Server. (Command line interface is preferable)
4) The solution needs to be easily implementable, that is, this solution will be implemented many times over.
I found many articles explaining how to set up a Windows box to connect to the BI Server in this way. However, these articles outline how to use tools like Excel and Microsoft Query to pull data from the BI Server. Our current user is using SQLplus.
If possible, I would like the user to continue using SQLplus as the tool for connecting to and retriving information from our BI Server. I have tested using SQLplus many different ways to no avail. I have also tried using other tools, such as Oracle SQL Developer.
Is there a program out there that will fulfill the needs I have outlined above? Or, does someone know of a way to use SQLplus to connect to the Oracle BI Server as a data source? Or, is there a series of solutions which will fulfill the needs outlined above?
Edited by: user11177366 on Jun 11, 2009 11:46 AM

I agree it would be inefficient but only because you are using OBIEE for something it was not designed to do. You are basically asking for a "DB feed" and that should designed using PL/SQL, DB Links, Web Services or whatever is your entreprise standard to send data from one system to another. Using OBIEE for this seems a bad architecture decision to me.You are correct, the BI Server is not really intended to be queried like another Oracle Database remotely. However, the reason we are trying to do it this way is twofold:
1) We want to enforce data level security.
2) The BI Server has been fine tuned for high performance.
Forcing the end users to go through the BI Server rather than directly to the physical tables or other sorts of systems built on top solves both of these issues.
I think you are wrong. I don't see why SQLPlus should be able to query the BI Server. The BI Server can sit on top of many different DBs not just Oracle, even flat files etc. So you can't really expect the BI Server to able to translate all that into Oracle SQL output so you can query it using SQLPlus. The BI Server is not an Oracle RDBMS.You're right again. The BI Server isn't an Oracle RDBMS, and I have been wanting to treat it like one. From the data I have gathered SQLPlus can't query the BI Server.
However, my research has led me to realize that the BI Server supports the JDBC API. Therefore, (I should have went down this route in the first place) one can use the JDBC driver provided by Oracle (bijdbc14.jar) to interface with the BI Server. There are many programs and applications out there that support the JDBC API and let us connect to BI Server the way we want to. Furthermore, these programs are mostly platform independent, as they are mostly written in Java.
Lastly, from what I understand the NQCMD program can be installed on any platform as well (provided by Oracle). This is another option to connect to the BI Server as well.
Thanks for your help and your comments as I went through this process of discovery.

Problem in data sources for transaction data through flat file

Hello Friends,
While creating the data sources for transaction data through flat file, I am getting the following error "Error 'The argument '1519,05' cannot be interpreted as anumber' while assigning character to application structure" Message no. RSDS016
If any one come across this issue, please provide me the solution.
Thanks in Advance.

Hallo,
just for information.
I had the same problem.
Have changed the field type from CURR to DEC and have set external instead of internal.
Then, the import with flatfile worked fine.
Thank you.

Using MS Access as a Data Source for BW

I have used MS Excel spreadsheets and 'mainframe' databases as data sources for BW in the past.
The company I ma working with has a large MS Access database containing historical sales data (from an R/3 3.1H system) that they wish to upload into BW v3.5 for comparison purposes.
My undersatnding was that MS Access was not a valid data source for BW. Could someone point out the error of my thinking and suggest how to set up MS Access as a data source.
Thanks in anticipation

Hi Austen,
Welcome onboard!
True, as far as I know, MS Access is not supported by BW. But you can use MSSQL instead. MSSQL is supported. I think the free version of MSSQL called MSDE (Microsoft SQL Desktop Edition) is also supported (Although I have not tried it yet)
Importing MSACCESS data to a similar table in MSSQL is very easy. Just use the Data Transfer Utility bundled with MSSQL. It will bulk insert data from MSACCESS to MSSQL. Then from MSSQL, you can set up BW to connect to it and you are done...
Hope I have helped. if I did, please grant points...

Jkyle

SAP HANA as a data source for Analysis Services

I tried to use SAP's .net provider for HANA as a data source for an Analysis Services cube but to no avail.   I can connect, create a named query and preview data from the data source view designer but when SSAS actually tries to run the query,
it wraps the named query in another query and produces a syntax error.
For example, if the named query is "select * from ENTHANA.MARA",
SSAS sends a query like this "SELECT [test].* FROM (select * from ENTHANA.MARA) AS [test]" (Test is the name of the named query).
I know SSAS wraps queries and that's fine - except that brackets are not a valid way to quote an identifier in HANA. HANA uses double quotes like Oracle.
Is there any setting in SSAS that can affect this behavior?   Will HANA ever be a fully supported data source for SSAS? If so, when?

Hi David,
According to your description, you are creating a SQL Server Analysis Services project, now what you want is using SAP HANA as the data source, right?
SSAS support many type of data source. However, as you can see on the link below, SAP HANA data source was not listed on that link. So this type of data source is not supported in current version of SSAS. Microsoft will update that document when it is supported.

Data Source for reused bounded task flow

Hi,
I am using JDeveloper 11.1.2.4.0.
I have a project from which I exported a bounded task flow to be used in other projects.
When I include that bounded task flow in a separate project, its data source does not appear in the Databindings.cpx of the project in which it is reused.
How will the data source for the reused task flow be set in the separate project?

I have a project from which I exported a bounded task flow to be used in other projects
By that you mean that you have crated a adfLibrary from the the task flow?
When I include that bounded task flow in a separate project
By that you mean you have added the adfLib created above to the other project from the resource palette, right click and 'add to project'?
How will the data source for the reused task flow be set in the separate project?
Once you have added the project you refresh the data control and the other task flow should show up.

Data source for this data connection isn't registered for Power BI

Hi, I am getting this error when I set Schedule Data Refresh to refresh data from db. How do I register my connection to the data source? Is this a fix on SQL server or Power BI?

Thanks for your help.

I'm running into the same issue, I did configure the Gateway and then the data source in Power Bi.
When I go to the Power BI Admin Center and click on "Test Connection" it seems to be working. But when I refresh the data from Power BI it doesn't work. Now if I edit the spreadsheet in excel and refresh the data in PowerPivot then it works. So
not sure why the solution doesn't refresh from the automated service in Power BI without this useless error.
Thanks
Fabian
In case it helps this is the actual error:

Data source for report

Hi guys.
Can somebody let me know how to set data source for report?
I did import "import.zip" and "bootstrp.zip".
I did run "HFPBMMAK.PRO".
I did create model connection of "HFPBM"
Best Regards,
Chul.

Chul,
You only have to import either import.zip OR the bootstrap.zip, not both.
I don't know if you have SSM 7.5 or SSM 10, this will be for 7.5
If you have followed the set-up correctly, you should be able to open the demolauncher -
http://localhost:50000/strategy/pilotworks/demolauncher.htm
Where localhost = server 50000 = port
You should open the Administrator interface of your demo and Set Scorecard Defaults. For a context make sure that the PAS Model Connection is set for the model connection you set - HFPBM.
You also need to make sure that Manage Application Groups have your user added for the context you selected.
(For 10 the application groups are managed in NetWeaver)

Bob

Recommendation for setting up Data Guard for EBS R12 12.1.3

Hello Experts,
I would like to get some experts opinion and recommendation on setting up Data GUARD for EBS R12.1.3 running on Linux based systems.
Firstly I would wanna let you all know that I am just geek in this subject matter so do excuse me for any mistakes.
While we are planning on setting up Data Gurad fro R12 what are the best practices to consider ?.
We have 2 node rac enabled database and would wanna have non-rac based physical standby, based on this I believe that having db tier on remote or standby site is enough ?
if db node is enough for standby location what are things to be done when a fail over / switch over / role transitioned to standby for the app node from primary site to point db on the
standby location or do we have to have both apps and db tier @ stand by location
--However having a apps tier/node at standby will be of no use as we are planing to run db on mounstate meaning not a active data guard setup.
Please do reply with your recommendation/suggestions/pointers
Thanks in Advance.
