C++ Application and Oracle Data Source

Hi everyone,
I am a bit of a newbie in this domain so am a bit confused with some of the options I have for my task. My task is to have a C++ application which will write/read/update data to/from an Oracle database. What are my options in this case?
I have read about OCI and OCCI, about ODBC drivers etc. but how does it fit in. If I use OCI or OCCI, do I need an ODBC driver (since from what I have seen, these aren't available for free and free is also one of the requirements)? If not, what do I need to be able to use OCI or OCCI?
If I am wrong and there are free ODBC drivers for Linux, where can I find them?
Or does this whole question sound like garbage? :(
Thanks in advance.

Hi,
This is my experience, if you know for sure that your application is going to execute always against a Oracle Data source, perhaps you shouldn't use ODBC and you should go for OCCI. This should be a good starting point:
http://www.orafaq.com/faq/oci
And here is another question, how can I set up a development environment to compile a C++ application (written using ODBC) on a Solaris server? I need the headers and the library against which I have to link the application. My Oracle database is 9.2.0.4.0.
Any help will be appreciated. Thanks!

Maintaining the structure of a SQL Server staging area and dwh aligned with the Oracle data source

Hi,
I'm working in a context where the data source system, in Oracle, is a continuos work in progress. Each 1-2-3 weeks the data source system in the prod environment is updated with new tables or updated table (with new columns or altered columns). So, it is
important to apply in a rapid manner the related changes in the data structure of the SQL Server staging area and dwh.
The issues to solve are:
a. maintaining SQL Server data structure of the staging area aligned with the data structure of the Oracle data source;
b. maintaing SQL Server data structure of the staging area aligned with the data structure of the SQL Server staging area.
In order to solve these issues it could be useful to think to an authomatic manner to alert when a data structure change occurs and a simple manner to apply the changes on SQL Server data structure.
Any suggests, please? Many thanks

We use Oracle CDC service in SQLServer. It has a flag to indicate the schema changes happening at the Oracle end. We track the schema changes using it and then apply changes to sqlserver side. And regarding automation you can use Biml as suggested or .NET
scripts inside script task.

Can SQL*Plus connect via ODBC to NON-Oracle data source?????

I am struggling to understand something. I downloaded Oracle instance client, SQL*Plus and ODBC components with the hopes of being able to connect via SQL*Plus to a non-Oracle/ODBC compliant database.
Is this possible? Or is SQL*Plus ability to connect via ODBC only to an Oracle data source??
Thanks...

sqlplus only connects to oracle. you can use the odbc driver from instant client to allow other applications to access oracle via odbc (e.g. excel). if you need to connect to non-oracle odbc database (ms-access, foxpro, etc.) you need odbc driver for those sources.
you can use sqldeveloper to connect to oracle and non-oracle databases. check otn product info for sqldeveloper for more details.

How to define data-sources-alias.xml to use Oracle data source

Hi,
I created Oracle jdbc Data Source named "MYDS" in Visual Admin. I added the alias = MYDS_ALIAS. I set the Initial Connection to 2. On the Monitor tab, I see a green line running across the screen. The datasource MYDS is connected to the Oracle.
Now, I would like to define "data-sources-alias.xml" to use MYDS.
When creating data-source-aliases.xml it creates the alias by default on ${com.sap.datasource.default} which is the default DB.
I followed the link --> How to point data-source-aliases.xml to another Datasource
and my data-sources-alias.xml is now:
<data-source-aliases>
     <aliases>
          <data-source-name>$</data-source-name>
          <alias>BRANCH50DS</alias>
     </aliases>
</data-source-aliases>
The "EAR generatation has finished successfully", but when "Deploy to J2EE Engine", I got the error below:
1) How to define data-sources-alias.xml to use Oracle data source?
2) I found the link (SDA Deployment error) talking about "sda-dd.xml". How to create "sda-dd.xml" and make it use substitution variables "MYDS"

Powerpivot Data Refresh Not working with Oracle Data Source in sharePoint 2013

I created a simple Excel 2013 PPIV workbook with an oracle data source and uploaded that to SharePoint 2013, but no change in the results - still getting the above error.
What is this error? We have installed Oracle client (64-bit, since we use 64-bit Excel and Sp is also 64-bit) on SSAS PPIV Server and SharePoint Content DB Server. Do we need
to install it anywhere else?
Thanks,

Hi Sonal,
To use PowerPivot for SharePoint on SharePoint 2013, it is required to install PowerPivot for SharePoint with the Slipstream version of SQL Server 2012 SP1. If you install SQL Server 2012 and then use the upgrade version of SQL Server 2012 SP1 to upgrade,
the environment will not support SharePoint 2013.
I would suggest you refer to the following articles:
Install SQL Server BI Features with SharePoint 2013 (SQL Server 2012 SP1):

Performance issue with Oracle data source

Hi all,
I've a rather strange problem that I'm stuck on need some assistance on.
I have a rules file which drags data in via an SQL data source thats an Oracle server. If I cut/paste the 3 sections of "select" "from" and "where" into SQL-Developer and run the query, it takes less than 1 second to complete. When I run the "load data" with this rule file or even use the "Retrieve" with the rules file edit, it takes up to an hour to complete/retrieve the data.
The table in question being used has millions of rows and I'm using one of the indexed fields to retrieve the data. It's as if the Essbase/Rule file is ognoring the index, or I have a config issue with the ODBC settings on the server that is causing the problem.
ODBC.INI file entry for the Oracle server as follows (changed any sensitive info to xxx or 999).

One other thing that I've seen is that if your Oracle data source and Essbase server are in different geographic locations, you can get some delay when it retrieves data over the WAN. I guess there is some handshaking going on when passing the data from Oracle to Essbase (either by record or groups of records) that is slowed WAY down over the WAN.
Our solution to this was remove teh query out of the load rule, run it via SQL+ on a command line at the geographic location where the Oracle database is, then ftp the resulting file to where the Essbase server is.
With upwards of 6 million records being retrieved, it took around 4 hours in the load rule, but running the query via command line took 10 minutes, then the ftp took less than 5.

CrystalReports error in XI 3.1 with Oracle Data Source

Having trouble running Crystal Reports with Oracle data source off XI 3.1 SP3. Reports hang through CMC or InfoView. Have no trouble on identical environment (presumably) with the same reports. Basically this happened after migration.
Report can be run on designer on the server box (suggesting the connection is good) however once uploaded to CMS, it hangs with error. This is not about an specific report only reports with Oracle Data source (Oracle client already installed and connection established)
Any comments appreciated.

Thank you for your reply.
Seems like a re-boot resolved the problem.

Help with Creating a Oracle Data Source

Hello:
I am trying to create a Oracle Data source.
I was successful in creating a JDBC Conection Pool.
But I am stumped creating a new datasource that uses the Oracle Connection Pool.
It asks for a JNDI Name and I have no clue what I should enter in this box.
Can somebody help me?
Thanks.
venki

Enter whatever name suits you. This is the name you will use when looking up your datasource in the JNDI tree, i.e.
Context ctx = new InitialContext();
DataSource oracleDS = (DataSource) ctx.lookup("myJNDIName");

Using Oracle Data Source in SSIS using Attunity

Hi,
I am using the oracle data source in SSIS.
* Created the expression that will have query to select source column.
* I need to extract only rows having specific date. This date is a dynamic one i.e Created a variable1 which will be update by function call(return type is datetime) for time being i have assigned the
value(datetime type).
* I have created one more variable2(string type) which will extract only date(dd-mon-yyyy). Below is the query i used.
{"select cast(DATEPART(dd, @[User::Cob_Dt] )as char(2))+'-'+cast(DateName(mm,DATEPART(mm, @[User::Cob_Dt] )) as varchar(3))+'-'+cast(DATEPART( yyyy, @[User::Cob_Dt]
) as varchar(4)) "}
* In source query expression i have used the variable but it showing "as missing expression". Though i tried a lot i cant get. some one please help. Below is thquery
{select * from table_name where ud.system_date =@[User::Date]
and... }
I have tried different formats like enclosing that between quotes(shows same error), then used to_Date() in oracle again shows same error.
If i hard code the value instead of @[User::Date] means its working well.
SomeOne please help me why that error is showing. I cant able to figure out. trying for whole day. PLEASE.
Thanks,

Directly in the source component, or in the expressions property of the data flow?
If the latter, what happens when you preview your expression?

Oracle Data Source for Essbase

Hi, Good Morning to ALL,
I have a doubt using Oracle Data Source with Essbase. When we use Oracle as the Data Source to load the data into Essbase cubes which of the following options would be better?
1. Is it better to create a single table or view, when the data is in multiple tables and then load into essbase?
OR
2. Is it better to join the tables by entering the SELECT statement in the Administration Services Console during the data load?
Which of these methods can be processed faster?
Please Advice.......
Thanks for the help in Advance...........

There are a couple of theories for loading Essbase from relational sources.
To be optimal there are techniques that you can create in the relational database to make joining more efficient.
Single View/Table
Everything you need in one large view. You can create one of these every period if you are performing incremental loads.
Star Schema
One large fact table all dimensions are represented with single Id foreign keys
One dimension table per dimension whose primary keys are connected to the fact
Snow-flake Schema
One large fact table all dimensions are represented with single Id foreign keys
Mutiple dimension tables per dimension whose primary keys are foreign keys in each connecting table then to the fact
These are the "text book" options; many other hybrid ways have been developed in recent years.
I would recommend using EIS against any relational source, as it will guide you through the OLAP loading process.

SQL LOADER , EXTERNAL TABLE and ODBS DATA SOURCE

hello
Can any body help loading data from dbase file .dbt to an oracle 10g table.
I tried last day with SQL LOADER, EXTERNAL table , and ODBC data source.
Why all of these utilities still failing to solve my problem ?
Is there an efficient way to reach this goal ?
Thanks in advance

export the dbase data file to text file,
then you have choice of using either sql loader or external table option to use.

Oracle Data Source Question

Can anyone tell me if the communication between a ColdFusion oracle data source and the Oracle database itself is encrypted or clear text by default? I'm assuming it is clear text unless other features, such as Oracle Advanced Security, have been implemented.
If it is data transmission is clear text, are the data source user name and password passed in clear text as well?

I dunno about the authentication info, but I'd say the rest of it would be clear text.
It might pay to have a look at the JDBC spec, or the docs for the driver you're using. That'll have the relevant info.

OBIEE report with HFM and Essbase Data source

Hi All,
Just want your though can we get the data from HFM and Essbase data source in a single report i.e. for some account i want to show budget data from HFM and Forecast data from essbase in a single OBIEE report? If yes how can we model both Data source in rpd?

It possible but the challenge is to try to align the account hierarchy and the entity hierarchy between Essbase and HFM. HFM is looking the data at a top side consolidation level where planning will have more granular details to forecast correctly. The best solution is either to build a custom table in to import both sources, or to use HFM data into Essbase, or to use EPMA. The best in class solution stays to align hierarchies and metadata across applications. We implemented BI Financials Dashboard for the General Ledger, built a custom Dashboard connected in Real Time to Planning and are installing OFMA to connect HFM. Once done, you can rationalize metadata if not done before and start to link the different data into single reports. You will also have to ensure the data is refreshed at the same time to avoid inconsistency.

Mapping deploy for Non-Oracle Data Source hangs

Hi All,
I am trying to deploy mapping for Non-Oracle Data Source and it hangs.
Oracle version is 10.2.0.3 and OWB version is 10.2.0.1.3.1
It would be really appreciated if you can help.
Thanks!
PS.

That helpes quite a bit. I still can't get the app to retrieve data, but I am getting a more useful message in the log:
[Error in allocating a connection. Cause: Connection could not be allocated because: ORA-01017: invalid username/password; logon denied]
As you suggested, I removed the <default-resource-principal> stuff from sun-web.xml and modified it to match your example. Additionally, I changed the <res-ref-name> in web.xml from "jdbc/jdbc-simple" to "jdbc/oracle-dev".
The Connection Pool "Ping" from the Admin Console is successful with the user and password I have set in the parameters. (it fails if I change them, so I am pretty sure that is set up correctly) Is there another place I should check for user/pass information? Do I need to do anything to the samples/database.properties file?
By the way, this is the 4th quarter 2004 release of app server. Would it be beneficial to move to the Q1 2005 beta?
Many thanks for your help so far...

Not able to connect to Oracle Data source in Oracle Essbase Studio 11.1.2.2

Hi,
When i tried to connect to Oracle data source, i get this error "Unable to establigh connection. Ensure that the server is running, the user name and password are correct, and the ohter data fields match the server's configuration" when i tried to select database.
If i change server name from to localhost, it allows to select database and does not give any error. but clicking on next button says localhost is not accepted, it needs machine name. Then how to connect to Oracle Data source?
Edited by: User006 on Oct 10, 2012 12:45 PM

It is possible the Oracle db has not been installed correctly, I take this is a personal install on a laptop, if so did you install the loopback adaptor.
Have you tried the connection using the ip of the machine.
