Converting an OLTP oracle 9i DB to a Datawarehouse DB

Hi Gurus,
I have a 9.2.0.6 DB running as an OLTP DB. now customer want us to configure this same DB as datawarehouse in same server.
need a quick help from you guys on this please... !!
appreciate any quick responese... thanks in advance...

Again, not too clear what it is you, or your client is asking. Is this server:
1. Being re-commissioned as a DWH server
2. Being asked to host another Oracle instance
3. Being asked to use a single instance for both OLTP and DWH responsiblities
Which is it please?
In regards to steps for transformation and hardware, those will actually come from the business requirements. You need to gather the requirements for the warehouse from the business owners and developers of the warehouse.
How much data will the warehouse hold and for how long?
What is the expected growth rate?
What will be the archive and purge policy?
What is the expected IOPS?
How much data do you expect to process per month, per day, or per hour?
Is there a requirement for a near-real time warehouse, or is processing only hourly, daily, monthly?
So many questions... these will determine your hardware requirements, physical and logical design.
Oracle along with vendors such as Sun, Dell, HP, IBM, not only offer warehouse reference architectures, but now also different 'warehouse appliances' (aka Oracle Optimized Warehouse Initiative)which are complete systems for warehouse databases based on size, and usage. See this link (http://www.oracle.com/solutions/business_intelligence/optimized-warehouse-initiative.html) for a look at the designs for a baseline to get you started.

How to I convert data from oracle database into excel sheet

how to I convert data from oracle database into excel sheet.
I need to import columns and there datas from oracle database to microsoft excel sheet.
Please let me know the different ways for doing this.
Thanks.

asktom.oracle.com has an excellent article on writing a PL/SQL procedure that dumps data to an Excel spreadsheet-- search for 'Excel' and it'll come up.
You can also use your favorite connection protocol (ODBC, OLE DB, etc) to connect from Excel to Oracle and pull the data out that way.

Error while converting schema from oracle to SQL server

Hello,
I am getting following error while converting schema from oracle to SQL server using SSMA.
I get Errors 1-3 while migrating procedures and error 4 while migrating a table.
1- O2SS0050: Conversion of identifier 'SYSDATE' is not supported.
2- O2SS0050: Conversion of identifier 'to_date(VARCHAR2, CHAR)' is not supported.
3- O2SS0050: Conversion of identifier 'regexp_replace(VARCHAR2, CHAR)' is not supported.
4- O2SS0486: <Primary key name> constraint is disabled in Oracle and cannot be converted because SQL Server does not support disabling of primary or unique constraint.
Please suggest.
Thanks.

The exact statement in oracle side which causing this error (O2SS0050:
Conversion of identifier 'to_date(VARCHAR2, CHAR)' is not supported.) is below:
dStartDate:= to_date(sStartDate,'MON-YYYY');
Statement causing error O2SS0050:
Conversion of identifier 'regexp_replace(VARCHAR2, CHAR)' is not supported is below.
nCount2:= length(regexp_replace(sDataRow,'[^,]'));
So there is no statement which is using to_date(VARCHAR2,
CHAR) and regexp_replace(VARCHAR2, CHAR) in as such. 'MON-YYYY' and '[^,]'
are CHAR values hence SSMA is unable to convert it from varchar2 to char.
Regarding SYSDATE issue, you mean to put below code in target(SQL) side in SSMA ?
dDate date := sysdate;
Thanks.

Convert CHARACTER in Oracle to TIMESTAMP

Hi,
One of the mapping in which our team works has one of the source columns from Oracle with Data type as timestamp.One of the sample data looks like
13-OCT-06 03.10.52.448000 PM.
When we pull in the data structure of source in Informatica, this column appears as a 'LONG RAW'. And it is moved forward in transformation as 'BINARY'.
This mapping fails if we do no modification to the data types in Informatica. We manually edited it to 'DATE', it worked but the data comes out with no Millisecond value in the target; I.e. the data is truncated. We need to retain the milliseconds portion of the date as well.
can anyone guide us how to convert CHARACTER in Oracle to TIMESTAMP, as we find the conversion can help us if we can not do it within Informatica
thx

TO_TIMESTAMP('13-OCT-06 03.10.52.448000 PM', 'DD-MON-RR HH12.MI.SS.FF AM')Regards...

Need inputs on CONVERT function in oracle.

My source DB is : US7ASCII
My target DB is : AL32UTF8
Basically I am using oracle CONVERT funciton to convert the data.
Unforutnately AL32UTF8 is not predefined in CONVERT function.
So, is there are any other ways to convert the data ? Plz let me know.
Thx,
Vi.

You have two databases. Database A uses a US7ASCII character set. Database B uses an AL32UTF8 character set.
- Is all the data in Database A actually US7ASCII data?
- What version of Oracle is Database A running? What version of Oracle is Database B running?
- On which database are you running the CONVERT function?
- Why do you believe you need to use the CONVERT function? If you are moving data from one database to another, Oracle should automatically take care of character set conversion.

Problem when converting to pdf - Oracle Reports 6i

Hi all,
Im using Oracle reports 6i and Oracle Database 10g Release 10.2.0.5.0 - 64bit Production.
In My database NLS_LANGUAGE is GREEK & NLS_CHARACTERSET is EL8MSWIN1253.
So i have greek language texts in the database..
When run the report, in the previewer the greek letters are fine,
But when i try to convert it into PDF, all the greek letters are not supported and letters are unknown characters.
i tried following,
SRW.DO_SQL ('ALTER SESSION SET NLS_LANGUAGE = '||'''GREEK''')
But still same problem....
Any workaround on this.. ?
Regards
SankarMN
Edited by: SankaraNarayanan.M.N on Dec 21, 2012 9:01 AM

Hi O.Developer,
I have set the greek language in the registry already, but still same problem persists.
In the Registry, i have the following value same as i have in the database nls parameters,
HKEY_LOCAL_MACHINE -> SOFTWARE ->ORACLE -> ORACLE_HOMES -> NLS_LANG -> AMERICAN_AMERICA.EL8MSWIN1253.
EL8MSWIN1253 is GREEK.
I could store greek values in the database and i can retrive it in the forms and reports as well.
My only problem is, when i try to convert the report into pdf, it is unknown characters.
And also i tried with modifying the file uifont.ali. But still no result...
Any other try is there to overcome ?

Date Calculation fails on Converted Access to Oracle Migration

I have converted an Access application to oracle database.
A select query calculates the months between the system date and a date stored in the Oracle Tables and it works you can view the results.
Another program using this query as source fails with a message
ODBC--Call Failed
[Oracle][ODBC][Ora]ORA-30081:invalid data type for datetime/interval arithmetic(#30081
This select query works displays the calculated “MONTHS_OLD” column
SELECT PR_main.PR_NUMBER, PR_main.SUBMISSION_DATE, Int((Now()-PR_main!submission_date-1)/30) AS Months_old, Int(Now()-[PR_main]![submission_date]) AS Days_old, PR_main.PROGRAM_ID, ATA_chapter_list.ATA_FUNCTIONAL_GROUP, PR_main.CURRENT_STATE
FROM PR_main INNER JOIN ATA_chapter_list ON PR_main.ATA_CHAPTER = ATA_chapter_list.ATA_CHAPTER_NUMBER
WHERE (((PR_main.CURRENT_STATE) Not Like "*Closed*"));
This query using the query above as the source, gives you the error
SELECT Count(ATA_time_query!pr_number) AS Count30, ATA_time_query.ATA_FUNCTIONAL_GROUP, ATA_time_query.PROGRAM_ID
FROM ATA_time_query
WHERE (((ATA_time_query.Months_old)<1))
GROUP BY ATA_time_query.ATA_FUNCTIONAL_GROUP, ATA_time_query.PROGRAM_ID;

I dont understand what you are asking? I think u are saying a part of our transformation is not right? Can you be specific about the function or where this is broken for you?

Converting MSACCESS into ORACLE Db

HI there,
would anybody happend to know how to convert MS access database into a Oracle Db.
I have heard that it is certainly possible, yet I am not sure how to do it.
Any info woudl be appreciated.
Thanks
Beno

One suggestion - don't use java. Not that java can't do it, but it is going to take a lot less time (but to run and to implement) using existing tools.
Use MS Access to export the data to text files. You get to it via the GUI.
Oracle has a import tool which reads in text files. I believe you need to create a description file. It uses that to figure out what the data looks like in the text file.
I believe that this is also fully explained in the Oracle docs or at least on the Oracle site. They might even have a tool there that does the entire process for you.

Converting a simple Oracle Report to XML Publisher report template

Hello,
I have a simple Oracle Report 9i which displays data from four tables. It uses three different queries to get the data. How can I simply generate a template file(say RTF) or atleast an XML source from that report? I tried joining the queries (like outer join) but wasn't able to get the format which report 9i was generating. Could anyone please help me out with a clear approach?

Hi,
Are you referring to how to get xml out put from seeded report i mean from EBS that already in oracle reports,
then you need to query from respective application by creating new concurrent program and then change the out put to XML, you will get xml file then save it to your system.
By using this input xml fle you can create RTF template whatever you want the foramat, after that you upload back this RTF file to EBS using XML PUBLISHER ADMINISTRATOR responsibility.
hope this might give you idea,
let us know if it is not clear or you are asking different question,

Convert shapefile to oracle spatial

Hi All,
I have a road network which is shapefile format and i want to export it to oracle spatial format using any free tool, any suggestion or guidance would be highy appretiated. I am using arcgis 9.3.1 and Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bi,
Best Regards,
Mich

Hi Mich,
That must be one of the most commonly asked questions on this forum, so have a search for "shape" and you won't be short of ideas.
A Google search will also give you countless suggestions. https://www.google.com/search?q=oracle+spatial+shape+file
For a GUI driven tool, I would recommend using the GeoRaptor plugin for SQLDeveloper which has an excellent shape file importer/exporter (http://sourceforge.net/projects/georaptor/).

Convert Date using ORACLE WAREHOUSE BUILDER

Hi,
I need to convert date format from 'DD/MON/YYYY' to 'YYYY/MON/DD'. The data is varchar(2) and in the database is stored as date. I am using expression component.
I used this expressionS REPLACE(TO_CHAR(INGRP1.FROMDATE), 'YYYY-MON-DD') REPLACE(TO_CHAR(INGRP1.TO DATE), 'YYYY-MON-DD') and it gave me an error: literal does not match format string.
Can anyone help me! PLEASE. IT'S URGENT

You are in the wrong forum. This is the forum for the SQL Developer tool. You wll get better answer from Warehouse Builder forums or from then SQL and PL/SQL forum.
To convert varchar to date use the to_date function, In your case something like
to_date(date_field,'DD/Mon/YYYY');

Convert!(SQLSERVER- Oracle!!)a trigger question!!

in the SQLSERVER,the trigger is writed this:
CREATE Trigger OnInsertBbname
on dbo.bbname
for insert
as
declare @bbname varchar(20)
declare @Sql varchar(1000)
select @bbname = bbname from inserted
if Not Exists( select * from Sysobjects where id = object_id(N'[dbo].['+@bbname+']') and objectproperty(id,'IsUserTable')=1 )
     begin
          set @Sql =
          'Create Table temptable'+
               temp varchar(10)
          exec(@Sql)
     end
question:
to covert oracle??

You cannot execute DDL in a trigger, since Oracle issues an implicit commit before and after DDL statements and you are not allowed to commit in a trigger. If you really need to create a table in response to inserting a row in this table, you would need to do so asynchronously either by scheduling a job or queueing a message and having the job/ queue consumer create the table.
I would seriously question the need to create the table, though. While individual sessions can create tables in SQL Server, temporary table definitions in Oracle are always visible to all sessions, though the data is visible only to individual sessions.
