I created a data warehouse in oracle 10g n with three Dimension and one cube after that it crates 4 tables . How to use an insert sql statement to insert data in those tables n how to access them.
View 7 RepliesWe have this archicture:
OLPT DB --> OLPT DB (Physical Standby, active dataguard) --> Data warehouse DB
We only allowed to connect to OLPT DB (Physical Standby, active dataguard) from Data warehouse DB. If there is possibility to use some of Oracle "native" method of data extraction (replication) from OLPT DB (Physical Standby, active dataguard) to Data warehouse DB.
As far as I know we cannot create materialized view log in OLPT DB (Physical Standby, active dataguard) in order to do data replication, but maybe there is some others ways?
We have got a new requirement wherein, The customer wanted the DBA Vendor (US) NOT to access the confidential information (ALL Columns) in the DB tables of PRODUCTION database. This is for few applications to comply with with export control rules. The thin support by Customer DBA will be allowed to access the Data, if required .
1) Web Based Interface ?.
2) DB Encryption (But if we encrypt ALL columns Serious performance issue expected, File level will not restrict DB level access)
3) Special setting on DB (DBA to do only backup and restoration related work only - But cannot access data)
4) Standard Tools / Utilities / Others ??.
Technologies are Oracle ,SQL
My data warehouse application involves partitioned tables where indexes are originally unusable on the last partition and only built until the next partition is created. We have a query tool that our users use to query this table that has an option "include not indexed data", which is essentially telling the tool whether to include that last partition in the query. IF this is checked, and they are filtering against on of the indexed fields, there is the potential for an Oracle error stating it tried to use an unusable index so our tool basically builds the query like this:
select ... from (
select ... from table where partition_key < (last usable partition key)
union
select /*+ NO_INDEX */ ... from table where partition_key >= (last usable partition key)
)
where
index_field = :value
I have had a difficult time getting reasonable data to test this myself, so I'm asking the question here:
Is Oracle probably pushing that outer filter into the inner individual queries in the UNION? If we were to move the index_field filter into the inner query against each of the individual queries in the union, would it make a difference performance-wise?

I am trying to build a data warehouse for Consumer Price Index and so I have downloaded data from the Bureau of Statistics.It is in excel format and since I am working with Oracle Warehouse Builder I have converted it to .csv file so that I can use it as a data source.
Question1: Is it practical to use single .csv file as a source of data for a data warehouse?
Question2: I have 3 dimensions tables and a fact table.The dimensions are one for the Region(as the date is organized in region,states etc),two is the consumer goods and services (as the data is organized in groups of goods and services, services/goods types) and finally time(year and month),
Now how am I going to do the mapping here?Is it possible to do a one to one mapping here as all data required by the dimensions is located in the .csv file.
Before I begin, I want to clarify that I am newbie in the administration of data warehouse.I need to know how to calculate the sizes of the archive and redo on data warehouse DB, in order to make an initial sizing of the BD on disks level.
Is there a formula to calculate the size?

We are working on a Data warehouse (ard 50G ) architecture with the following acquired environment:
Single server X3650 M4 Dual CPU ( 16 core in total ) with 48G ram
Oracle standard 10g x64
Windows 2008 x64
128 SSD x 8
IBM ServeRAID M5110e SAS/SATA Controller
Due to budget concern, we will be running the App server(Business OBjects 4.0 w/ Tomcat and DB server on the same machine. ) We have a user base of around 30 ppl on the app server.
We intend to have external redundancy using IBM raid card on raid 10 configuration. I wonder what kind of disk config yield better performance if we only have write update in the morning and 95% read for the rest ?
Raid 1 for OS (128SSD x 2 including DB logfile )
Raid 10 for DB server ( 128 SSD x 6 )
I heard ASM provides better disk management but just wonder it increase performance in anyway.
The following code is a stored procedure I plan to use to populate a Data Warehouse dimension using data from two OLTP tables which already exist in my database. Notice that in my cursor select statement, I calculate an attribute using substr and instr, and I also assign a true or false value to a flag using a CASE statement.
CREATE OR REPLACE PROCEDURE populate_product_dimension
AS
v_Count NUMBER := 0;
v_NumRecs NUMBER;
/*Declare a cursor on the following query which returns mulitple rows of data from product and price_hist tables*/
[code]....
In my mind, Product_Code is declared correctly in the Cursor declaration Select statement.
I'm writing a Procedure which Updates or Inserts data in Multiple tables. Selected fields of 10 tables need to be updated or Inserted. For this I created a table which comprises of fields related to all 10 tables. Then I write Procedure. Under this I create a Cursor which uploads the data from the newly created table which contains different fields of 10 tables. Then I write Update and Insert statements one by one for all 10 tables.
Sample Procedure below.
-------------------------------------------
Create or replace procedure p_proc as
spidm spriden.spriden_pidm%type;
cursor mycur is select * from mytable;
begin
for rec in mycur
[code]......
----------
Note: I created table on my server because data is coming from different server. They will upload the data in the table from there I pick and update the tables. Is updating or Inserting data in different tables one by one is correct?
I need to export only the data from schemas or tables, how to do that with Oracle Data Pump? when we use schemas parameter this export all schema, not only the data right?

I have to cleanup data from our tables (Production Environment) that contain millions of rows. The question is apart from the solution of the partitioned tables what alternative recommended solution suggests Oracle?
To delete these tables by using a cursor PL/SQL block or to import all the database and in the tables that we want to remove the old rows to use the QUERY option of the data pump utility.
I have used both ways and i have to admit that datapump solution is much much faster than the deletion that suffers from I/O disk.The question again is which method from these two is more reliable and less risky for the health of the database.
I came across an implementation where data from DB2 tables are moved to Oracle tables, for BI solutioning, using some oracle procedures called from MS SQL DTS packages which are scheduled jobs.Just being curious, can this be done using OWB or ODI rather than the above detour. I suppose there are some changes being done in those procedures before the data is being loaded into Oracle tables, can't this be done using OWB/ODI? Can it be scheduled too as jobs using OWB/ODI?
View 1 Replies View RelatedI would like my application to have access to 2 different data sources [reached by two different database links]:
- DS_ONLINE that would be the main data source dedicated for an ONLINE access
- DS_OFFLINE, consisting of some materialized views which would refer to the objects of the DS_ONLINE data source, maintained in case of the DS_ONLINE's temporary inaccessibility A flag DS_ONLINE_ACCESS_FLAG indicating the DS_ONLINE's accessibility would be maintained.
I would like to make the choice of the current data source TRANSPARENT to my PL/SQL application [I wouldn't like the logic of determining the current data source to be embedded in my application code]. How can I do it?
I thought I could write the code as follows:
OPEN CURSOR c FOR
SELECT A, B, C FROM TABLE_SYNONYM;
Where the definition of the TABLE_SYNONYM would change in function of the DS_ONLINE_ACCESS_FLAG flag.
It could be done as DDL statement of "create or replace synonym ..." placed in a procedure dedicated to set the DS_ONLINE_ACCESS_FLAG flag...
...but I'm not sure if it is going to work and even so
when i create db link then it show below:

Is there a way to apply changes to a data field on oracle forms for specific users?
For example, I have an oracle form that applies the below masking code for a certain field called CUSTOMER_ID
IF :SYSTEM.BLOCK_STATUS = 'QUERY' THEN
SET_ITEM_PROPERTY('CUSTOMER_ID',CONCEAL_DATA,PROPERTY_TRUE);
ELSE
SET_ITEM_PROPERTY('CUSTOMER_ID',CONCEAL_DATA,PROPERTY_FALSE);
END IF;
But I only want this masking to be applicable to CERTAIN users. For example, the psuedo code would be like
IF :SYSTEM.BLOCK_STATUS = 'QUERY' and USERS_LIST = 'SUPERVISORS' THEN
SET_ITEM_PROPERTY('CUSTOMER_ID',CONCEAL_DATA,PROPERTY_TRUE);
Note that this users_list is a group of oracle database users, so I am a member of this group. Also note that this form is applied via the web via the application server.

View 8 Replies View RelatedI have installed APEX on my local machine, created a workspace, and added a few users with roles.
I am creating an application, similar to a Library app, where I have a table that stores Books information (BOOK_ID, BOOK_NAME, etc). I'd like to create another table BOOK_USER with two columns, BOOK_ID and USER_ID. BOOK_ID would refer to the BOOKS table, and I want USER_ID to refer to the table that stores user details of the workspace that I am using. The data entry would happen from a page that has two LOVs, one for book name (using BOOK_ID as the value) and another for user name (USER_ID, or whatever field APEX uses to store user's ID). Can I do that in APEX? I've found ways to access and authenticate a user for a page, but how to get data of all users in the workspace? In other words, how to get all usernames in a LOV?
Is it possible for Access to extract data from an Oracle database and upload it directly?
Currently we have a business process where data is being extracted in scheduled queries (30+) to Excel spreadsheets, then manually edited to remove heading lines and imported to an Access database. I see an opportunity to automate a time consuming manual activity by having the Access db extract the data and directly upload it.
