Retreiving a date from database and converting it into a string in a format

hi all,

If the field is a Date in your database, you can use the ResultSet.getDate() method, which will return a java.sql.Date (which extends java.util.Date).
You can then use SimpleDateFormat to format it the way you like.
See the API doc for more details.

How to query data from database and store it into Managed Bean ?

Hi all,
In our application we have requirement to store information within Managed Bean to be accessed by ADF pages.
The information is stored in database tables.
The question is :
What is the efficient / recommended way to do that ?
I do not use apps module to query the data because the information is required in View layer not the model layer
Thank you for your help,
xtanto

Xtanto,
if the information is stored in the database then the question is if there is a database connect open already. If yes, then why not using this connection to query for the data you want to access and store. Alternatively you can directly open a JDBC connection in a managed bean or access an EJB session bean. However, this comes with the price of an extra database connection.
Make sure the managed bean is in session scope if you want to share the information without re-fetching it

How to Extract Data from SAP and Load it into Essbase

Hi All,
Can you recommend some ways to extract data from SAP and load it into Essbase?. I have no knowledge about SAP, not sure how I can perform this task. Can I use ODI for this job?
Thanks

hi,
Not sure if this helps but give a try
you can create connection from EAS to SAP .. using a plug-in .. if you have access to oracle Support go for [ID 968961.1]
or
below are steps
1. In EASPATH\console, open components.xml in a text editor.
2. Under <PluginList>, enter <Plugin archiveName="SAP" packageName="com.essbase.eas.sap.ui"/> before the closing </PlugIn> tag.
3. Save and close the file.
4. In EASPATH\console\bin, open admincon.lax in a text editor.
5. Search for lax.class.path= and append ;..\lib\sap_client.jar;..\lib \sap_common.jar to the entry. Save and close the file.
6. In EASPATH\server\bin, open adminsvr.lax in a text editor.
7. Search for lax.nl.java.option.additional, and append -DRFC_INI=EASPATH\server\saprfc.ini. Save and close the file.
8. Create a new environment variable, RFC_INI, with a value of EASPATH\server\saprfc.ini
9. Copy librfc.dll andsapjcorfc.dll to EASPATH\server\bin. You may need to obtain these files from SAP.
let me know if it works :)

Selecting the data from database and sending to users using javamail

how to select the records from database table in oracle and send automatically to users using javamail. I am able to send the txt msg. but dont know how to send the selected table data to users automatically.
can anyone suggest how to write the steps with database connection to send msgs containing data to different users
Thank You

using JDBC..you want to
1. create the connect
2. open the connection
3. query the table for the data
4. loop through the resultset to retrieve rows of data
5. do something with the data
6. email the result
once you have the data, it is up to you to determine the format to send to the user using JavaMail. It is easiest to send plain text
here's a site that give code example (for all steps above relating to JDBC):

Dynamically fetch data from database and display it in the report

Hi,
We have a requirement in developing a report which needs us to dynamically fetch data from the database and display it in the report.
We have a column called WORKER in the report.
For each worker there is a measure(PSA) associated with it.
In the report we have to display both the WORKER and the PSA column.
What we want is, when we display the list of the workers, the corresponding workerid_id of the worker will be passed and the value of his PSA will be fetched from the database and displayed in the report.
Or anything similar to this.
We also have drill applied on this WORKER column. So after any drill up or drill down also the value for PSA should change.
Is there any way of doing this?
Please help if possible.
Thanks,

Extracting data from SAP and dumping it into Non SAP System

Hi All,
We have an MS based in house system. For our business process improvement, we need to import our customer's data and dump it into our application that has SQL server database - Our customers are running SAP. Wanted to find out what steps we need to follow from the design perspective... also I am assuming we wll need an access to our customer's system to code RFCs - is that correct ? Any information will be highly appreciated.
Thanks,
Neelima.

Hi,
it's really hard to answer your question without additional knowledge of your landscape. SAP support many ways of integrations. One way is using RFC. You would simply call function modules from your .NET application using RFC library. Another way is using web services. You can easily expose any RFC enabled function module as web service (if you are on NetWeaver). Another solution is using REST interface. Recently, there have been many articles dedicated to this approach here on SDN. This can be pretty nifty solution. Another way is file based integration (IDocs or simple flat files transfered via FTP).
Cheers

How to extract data from CLOB and insert them into DB?

Hi PL/SQL Gurus,
I have no experience in PL/SQL, but I have a requirement now where I have to use it.
We have a table with 10 columns, one of them is a CLOB and it holds XML data. The XMLs are very huge in size.
Two new columns are added to the table and the data has to be filled for the existing records from the corresponding XML. The XML has all the data as attributes. I started searching on the internet and tried if I could extract the data out of XML.
SELECT extractValue(value(x), '/Order/Package/@Code',
'xmlns:ns0="http://mycompany.com/Order/OrderType.xsd"' )
FROM ORDER_TABLE A
, TABLE(
XMLSequence(
extract(
xmltype(A.XML_DATA)
, '/ns0:Root'
, 'xmlns:ns0="http://mycompany.com/Order/OrderType.xsd"'
) x;
But this isn't working. Could anyone please provide some ideas.
I just want to confirm that I am able to extract data. Once this is done I would like to create a procedure so that all the existing records can be updated.
Thanks in advance.
Regards,
Fazzy

How to fetch data from SolMan and move it into SAP BI?

Hi all,
I have the portal activity report data residing in the SolMan ( achieved by configuring portal and SolMan). I need to extract this data from Solution Manager into SAP BI, such that i can report on the data in SAP BI using the BEx tools. How will i proceed with it ? Your response is higly appreciated.
Regards,
Divya.

Hello Divya,
You must set up E2E Diagnostics for the managed system (portal system).
You can accomplish this by running transaction solman_setup in the Sollution Manager and ensure that Initial and Basic Configurations are performed. Afterwards, you must follow the Managed System Configuration (also in solman_setup) for the managed system.
Afterwards you must activate some specific Portal Activity Data Collectors following the note 1309740.
Best regards,
Guilherme Balbinot

Extraction of data from Planning and load it into Oracle/SQL server (RDBMS)

Hi All,
ODI can extract data from Oracle/SQL server RDBMS and load it into Hyperion planning, but I wanted to know if it is possible to extract data from Hyperion Planning through ODI and load it into Oracle or SQL server RDMBS i.e the other way round.
Kindly let me know if that is possible or not,If yes then please let me know what is the exact process to achieve this through ODI.
Thanks & Regrads,
Gurpreet

Yes this can be done. Remember that Planning data is actually stored in Essbase so the Knowledge module you will need to use is LKM Essbase to SQL (DATA)
